Abstract: We sequenced most of the mitochondrial genome of the sawfly Perga condei (Insecta: Hymenoptera: Symphyta: Pergidae) and tested different models of phylogenetic reconstruction in order to resolve the position of the Hymenoptera within the Holometabola, using mitochondrial genomes. The mitochondrial genome sequenced for P. condei had less compositional bias and slower rates of molecular evolution than the honeybee, as well as a less rearranged genome organization. Phylogenetic analyses showed that, when using mitochondrial genomes, both adequate taxon s ling and more realistic models of analysis are necessary to resolve relationships among insect orders. Both parsimony and Bayesian analyses performed better when nucleotide instead of amino acid sequences were used. In particular, this study supports the placement of the Hymenoptera as sister group to the Mecopterida.

Abstract: Despite the extraordinary morphological and ecological ersity of Neritimorpha, few studies have focused on the phylogenetic relationships of this lineage of gastropods, which includes four extant superfamilies: Neritopsoidea, Hydrocenoidea, Helicinoidea, and Neritoidea. Here, the nucleotide sequences of the complete mitochondrial genomes of Georissa bangueyensis (Hydrocenoidea), Neritina usnea (Neritoidea), and Pleuropoma jana (Helicinoidea) and the nearly complete mt genomes of Titiscania sp. (Neritopsoidea) and Theodoxus fluviatilis (Neritoidea) were determined. Phylogenetic reconstructions using probabilistic methods were based on mitochondrial (13 protein coding genes and two ribosomal rRNA genes), nuclear (partial 28S rRNA, 18S rRNA, actin, and histone H3 genes) and combined sequence data sets. All phylogenetic analyses except one converged on a single, highly supported tree in which Neritopsoidea was recovered as the sister group of a clade including Helicinoidea as the sister group of Hydrocenoidea and Neritoidea. This topology agrees with the fossil record and supports at least three independent invasions of land by neritimorph snails. The mitochondrial genomes of Titiscania sp., G. bangueyensis, N. usnea, and T. fluviatilis share the same gene organization previously described for Nerita mt genomes whereas that of P. jana has undergone major rearrangements. We sequenced about half of the mitochondrial genome of another species of Helicinoidea, Viana regina, and confirmed that this species shares the highly derived gene order of P. jana.

Abstract: Birds are important hosts in the life cycle of some species of ticks. In Colombia, there are few eco-epidemiological studies of tick-borne diseases the existing ones have been focused on areas where unusual outbreaks have occurred. This study describes the identification of ticks collected from birds and vegetation, and the detection of bacteria in those ticks and in blood s les from birds in an urban fragment of tropical dry forest in the department of Magdalena, Colombia. Bird s ling was carried out monthly in 2021, and 367 birds, distributed among 41 species, were captured. All collected ticks were identified as Amblyomma sp. or Amblyomma dissimile. The presence of rickettsiae in ticks collected from birds was evaluated by molecular analysis of the gltA, ompA and sca1 genes. 16S rRNA meta-taxonomy was used to evaluate rickettsiae in ticks collected from vegetation and in blood s les from birds. The presence of the species “Candidatus Rickettsia colombianensi” was detected in ticks from birds. Bacteria of the family Rickettsiacea was the most abundant in ticks collected from vegetation. Bacteria of the families Staphylococcaceae, Comamonadaceae and Pseudomonadaceae were prevalent in the s les of blood from birds. Rickettsia spp. was also detected in low abundance in some of the bird blood s les.

Abstract: We characterized the organization of mitochondrial genes from a erse range of hymenopterans. Of the 21 taxa characterized, 12 had distinct, derived organizations. Some rearrangements were consistent with the duplication-random loss mechanism, while others were not. Local inversions were relatively common, i.e., rearrangements characterized by the movement of genes from one mitochondrial strand to the other, opposite or close to their ancestral position. This type of rearrangement is inconsistent with the duplication/random loss model of mitochondrial gene rearrangement. Instead, they are best explained by the operation of recombination. Taxa with derived organizations were restricted to a single, monophyletic group of wasps, the Apocrita, which comprise about 90% of all hymenopterans.

Abstract: Domiciliated Rhodnius prolixus and sylvatic R. colombiensis were analyzed in order to confirm their genetic ergence and verify the risk that the latter represents in the domiciliation process, and to provide tools for identifying the sources of possible reinfestation by triatomines in human dwellings allowing control programs to be undertaken. Comparison of random lified polymorphic DNA lification patterns and cluster analysis suggests reproductive discontinuity between the two species. The calculated statistical F value of 0.24 and effective migration rate of 0.6 in iduals per generation are insufficient to maintain genetic homogeneity between them and confirm the absence of present genetic flow. R. colombiensis presents higher intrapopulation variability. Polymerase chain reaction of ribosomal DNA supports these findings. The low genetic flow between the two species implies that R. colombiensis do not represent an epidemiological risk for the domiciliary transmission of Trypanosoma cruzi in the Tolima Department. The lower variability of the domiciliated R. prolixus could result in greater susceptibility to the use of pesticides in control programs.

Abstract: In the present study, we determined the mitochondrial DNA (mtDNA) sequence of three Neritas, Nerita versicolor, Nerita tessellata, and Nerita fulgurans. We present an analysis of the features of their gene content and genome organization and compare these within the genus Nerita, and among the main gastropod groups. The new sequences were used in a phylogenetic analysis including all available gastropod mitochondrial genomes. Genomic lengths were quite conserved, being 15,866bp for N. versicolor, 15,741bp for N. tessellata and 15,343bp for N. fulgurans. Intergenic regions were generally short genes are transcribed from both strands and have a nucleotide composition high in A and T. The high similarity in nucleotide content of the different sequences, gene composition, as well as an identical genomic organization among the Nerita species compared in this study, indicates a high degree of conservation within this erse genus. Values of Ka/Ks of the 13 protein coding genes (PCGs) of Nerita species ranged from 0 to 0.18, and suggested different selection pressures in gene sequences. Bayesian phylogenetic analyses using concatenated DNA sequences of the 13 PCGs and the two rRNAs, and of amino acid sequences strongly supported Neritimorpha and Vetigastropoda as sister groups.

Abstract: We sequenced the entire mitochondrial genome of Abispa ephippium (Hymenoptera: Vespoidea: Vespidae: Eumeninae) and most of the mitochondrial genome of Polistes humilis synoecus (Hymenoptera: Vespoidea: Vespidae: Polistinae). The arrangement of genes differed between the two genomes and also differed slightly from that inferred to be ancestral for the Hymenoptera. The genome organization for both vespids is different from that of all other mitochondrial genomes previously reported. A number of tRNA gene rearrangements were identified that represent potential synapomorphies for a subset of the Vespidae. Analysis of all available hymenopteran mitochondrial genome sequences recovered an uncontroversial phylogeny, one consistent with analyses of other types of data.

Abstract: Despite recent efforts, hypothesised phylogenetic relationships among apocritan wasps remain unresolved. In this study, molecular analyses were employed to analyse a dataset that included the 16S, the 28S and the COI genes of 87 apocritan representatives. Partial sequences of the 18S gene were also generated and added to this dataset. The topological effects of outgroup choice, method of phylogenetic analysis, and inclusion of the 18S data were systematically investigated, with particular focus on the relationship of the Chalcidoidea with other members of the Proctotrupomorpha (Platygastroidea, Proctotrupoidea, Cynipoidea). We report that ingroup topology was sensitive to the choice of outgroup, the method of phylogenetic analysis, and inclusion of 18S data. However, the Proctotrupomorpha were always monophyletic, and the Chalcidoidea were recovered, in every analysis except one, as the sister to the diaprioid complex (Diapriidae + Monomachidae + Maamingidae). The single exception, where the Chalcidoidea + Platygastroidea were recovered, utilised a more distant outgroup (Symphyta : Cephidae : Hartigia), maximum parsimony, and excluded the 18S data. Our results suggest the Chalcidoidea + (Diapriidae + Monomachidae + Maamingidae) relationship is more likely.

Abstract: We sequenced most of the mitochondrial (mt) genomes of 2 apocritan taxa: Vanhornia eucnemidarum and Primeuchroeus spp. These mt genomes have similar nucleotide composition and codon usage to those of mt genomes reported for other Hymenoptera, with a total A + T content of 80.1% and 78.2%, respectively. Gene content corresponds to that of other metazoan mt genomes, but gene organization is not conserved. There are a total of 6 tRNA genes rearranged in V. eucnemidarum and 9 in Primeuchroeus spp. Additionally, several noncoding regions were found in the mt genome of V. eucnemidarum, as well as evidence of a sustained gene duplication involving 3 tRNA genes. We also report an inversion of the large and small ribosomal RNA genes in Primeuchroeus spp. mt genome. However, none of the rearrangements reported are phylogenetically informative with respect to the current taxon s le.Key words: mitochondrial genomes, molecular evolution, hymenoptera.

Abstract: Parasitoses are an important health problem and its post-infectious consequences can cause high morbidity and mortality, worldwide. Epidemiological data is scarce in our region. We aimed to obtain frequency and circulating genotypes of Giardia intestinalis in two cities of the Caribbean Coast. To identify parasites in s les, a fecal concentration and microscopical examination were performed. For further identification and genotyping of G. intestinalis, molecular analyses were performed using specific available primers. Only 22.1% of participants had gastrointestinal symptoms (most frequently: abdominal pain and diarrhea). Microscopy examination was positive in 72.7% of the s les. The most frequent parasite was G. intestinalis (48.1%) and we found mixed parasitic infections in 46.7% of the participants. All the s les from Santa Marta were molecularly characterized as assemblage A of G. intestinalis, while in Cartagena we confirmed the presence of assemblages A and B. Molecular tools are important in the diagnosis of parasites and to increase comprehension of their distribution. In this study, a higher frequency of parasites, mostly protozoa, was observed.

Abstract: Although more reptiles are illegally traded in Colombia than any other group of animals, for both local and international markets, little is known about ticks associated with reptiles or pathogens associated with these ticks. In this study, ticks were collected from reptiles in Magdalena, Cesar and La Guajira regions in northern Colombia, and identified morphologically using taxonomic keys and molecularly by sequencing of the COI gene. In addition, Rickettsia spp. were detected by PCR lifying the gltA, 16S rRNA, and sca1 genes. Ticks were identified as Amblyomma dissimile, representing the first record for this species in 17 of the 26 species of reptiles s led. Additionally, our data expand the distribution range for this tick in Colombia. Rickettsia spp. DNA was detected in 18 ticks (3.6%) from 16 reptiles. Sequence analyses indicated that most of the Rickettsia were members of the R. monacensis clade, most closely related to Rickettsia sp. strain Colombianensi. We detected one tick infected with a Rickettsia with 99% identity to R. bellii.

Abstract: Objetivo Comparar secuencias de nucleótidos y de aminoácidos de la proteína no estructural 1-NS1 de cepas DENV-2, aisladas de pacientes febriles de diferentes paises suramericanos, que cursaron cuadros clínicos con severidad o sin ella.Materiales y Métodos El análisis filogenético fue realizado a partir de 28 secuencias moleculares completas (1 056 pb) del gen NS1 del serotipo DENV-2. Se realizó un análisis filogenético bayesiano utilizando el software MrBayes v.3.2.0, con el modelo SYM+G y un análisis filogenético con el método Neighbor-Joining con el modelo Jukes-Cantor. Además, las secuencias de aminoácidos fueron alineadas y comparadas entre sí, mediante el programa Clustal W incluido en el software MEGA v. 5.2.Resultados En las secuencias de aminoácidos asociadas a sangrado, la sustitución más frecuente fue isoleucina® treonina, en la posición 93. Estas secuencias presentaron un mayor porcentaje (94,6 %) de homología de aminoácidos de la proteina NS1 en comparación con el porcentaje de homología (74 %) de los aislamientos DENV-2 no asociados a sangrado. Se identificaron cinco clados que agrupan la mayoría de las secuencias analizadas (19/24 79,2 %) con valores de probabilidad posterior mayores o iguales al 58 %. Siete (87,5 %) secuencias asociadas a sangrado se relacionan filogenéticamente dentro de los clados 4 y 5, con valores de probabilidad posterior del 58 % y 97 %, respectivamente.Conclusion No se encontraron características filogenéticas ni t oco diferencias entre las secuencias de aminoácidos de la proteína NS1-DENV-2 estudiadas, que pudieran ser relacionadas, de manera directa, con la severidad de la enfermedad.

Abstract: This is the first report of the mitochondrial gene order and almost-complete DNA sequence of a representative of the Neritimorpha, the highest-ranking gastropod clade lacking such data. Mitochondrial gene order in Nerita is largely plesiomorphic. Its only difference from the cephalopod Octopus vulgaris is a tRNA transposition shared by Vetigastropoda and Caenogastropoda. Genome arrangements were not informative enough to resolve the evolutionary relationships of Neritimorpha, Vetigastropoda and Caenogastropoda. The sister-group taxon of Neritimorpha varied in sequence-based analyses. Some suggested that Neritimorpha is the sister group of Caenogastropoda plus Heterobranchia and some that Neritimorpha and Caenogastropoda are sister groups. No analysis significantly supported the hypothesis that Vetigastroda is more closely related to Caenogastropoda than is Neritimorpha.

Abstract: The aim of the present study was to provide insight into the ersity of tick-borne pathogens circulating in Italy, carried/transmitted by Ixodes ricinus, one of the most abundant tick species in the country. A total of 447 specimens s led in five areas of northeastern, central and insular Italy were analysed by polymerase chain reaction and sequencing for the presence of rickettsiae, borreliae and babesiae. Several rickettsial species of the spotted fever group of zoonotic concern and other zoonotic pathogens were found, such as Borrelia burgdorferi s.s., Borrelia afzelii, Borrelia garinii, and Babesia venatorum. These findings confirm a wide distribution of tick-borne bacterial and protozoan species in Italy, and highlight the sanitary importance of I. ricinus, often recorded as feeding on humans.

Abstract: The comparative phylogeography of marine species with contrasting dispersal potential across the southern Caribbean Sea was evaluated by the presence of two putative barriers: the Magdale-na River plume (MRP) and the combination of the absence of a rocky bottom and permanent upwelling in the La Guajira Peninsula (ARB+PUG). Three species of rocky shallow bottoms were selected with different dispersal potentials: Acanthemblemaria rivasi (PLD & 22 days), Cittarium pica (PLD & 6 days), and Nerita tessellata (PLD & 60 days). We generated a set of SNPs for the three species using the ddRad-seq technique. S les of each species were collected in five locations from Capurganá to La Guajira. For the first time, evidence of a phylogeographic break caused by MRP is provided, mainly for A. rivasi (AMOVA: ФCT = 0.420). The ARB+PUG barrier causes an-other break for A. rivasi (ФCT = 0.406) and C. pica (ФCT = 0.224). Three populations (K = 3) were identified for A. rivasi and C. pica, while N. tessellata presented one population (K = 1). The Mantel correlogram indicated that A. rivasi and C. pica fit the hierarchical population model, and only the A. rivasi and C. pica comparisons showed phylogeographic congruence. Our results demon-strate how the biological traits of these three species and the biogeographic barriers have influ-enced their phylogeographic structure.

Abstract: Ehrlichia canis and Anaplasma platys are intracellular tick-transmitted bacteria that infect dogs there is evidence for limited zoonotic potential as well. The prevalence of E. canis in Colombia has been evaluated in different regions however little is known about the prevalence or distribution of A. platys. Neither pathogen has been studied in the Magdalena region, thus the purpose of our study was to assess the prevalence of these pathogens in dogs attending veterinary clinics from the cities of Santa Marta and Ciénaga, and to assess possible associated risk factors for infection. A. platys and E. canis infections in blood were evaluated by Taqman PCR assays. E. canis was detected in 26/170 (15.3%, 95% CI 10.4%-21.8%) and A. platys in 34/168 (20.2%, 95% CI 14.6%-27.3%) of all dogs tested. Eleven dogs (6.5%, 95% CI 3.4-11.7%) were coinfected with both pathogens. Sequencing results showed low ersity within E. canis and within A. platys strains, however a strain of E. canis detected in our study area is genetically distinct from strains reported in another city of Colombia. Our results suggest that for A. platys, Santa Marta dogs were at greater risk than Ciénaga dogs, and that purebred dogs were at slightly lower risk in both areas. The confirmation of these pathogens in northern Colombia should cause concern for the possible co-transmission of these agents to humans or animals in the region.

Abstract: We sequenced the complete mitochondrial genome of the Heteronemertea species, Micrura ignea. The genome was lified with a combination of short and long PCRs that were subjected to 454 sequencing. The mitogenome of M. ignea is a circular molecule of 15,333bp in size and encodes the 37 genes typically found in metazoans, and one non-coding region. The order of the genes is the same as for all the other Heteronemerteans. All genes are encoded on the heavy strand except trnT and trnP. The phylogenetic analyses recovered M. ignea as a basal taxon in the Lineidae family, no differences were found in the topology of the phylogenetic trees in comparison with previous studies.

Abstract: Horses are among the domestic animals that closely interact with humans and are highly parasitized by ticks, which are the primary vectors of zoonoses. As horses in Tayrona National Natural Park (PNNT) are used as a means of transporting goods, luggage and people, they are in constant contact with wild animals, workers and tourists from different countries. These factors increase the transmission risk of hemoparasites. The purpose of this study was to determine the presence of Rickettsia sp., Anaplasma sp., and Theileria sp., in horse ticks in this protected area using conventional PCR. We collected 343 ticks of genera Amblyomma, Rhipicephalus and Dermacentor. Of the 61 s les analyzed by PCR, 18 (29.5%) in iduals were positive for Rickettsia sp., 15 (24.5%) for Anaplasma sp. and 4 (6.6%) for Theileria sp. This is the first report of these hemoparasite genera in ticks associated with horses in this preserved natural area, demonstrating the importance of additional studies on the presence and epidemiology of hemoparasites and their vectors in domestic and wild animals in conserved areas with a high flow of tourists.

Abstract: La entomología forense es una disciplina que utiliza insectos para obtener información útil en la determinación del intervalo postmortem (IPM). Las moscas de la familia Calliphoridae son muy utilizadas en entomología forense, sin embargo, su identificación a nivel de especie puede dificultarse cuando el in iduo se encuentra incompleto o en estadio inmaduro. En el presente trabajo, se evaluó el potencial de la región ITS2 del genoma nuclear para la identificación de especies de Calliphoridae en Colombia utilizando tres aproximaciones: comparando distancias genéticas utilizando la metodología de códigos de barra, haciendo una reconstrucción filogenética, y con enzimas de restricción (PCR-RFLPs). Se secuenciaron un total de 520 pb en 44 in iduos pertenecientes a 16 especies. Se calcularon los valores de distancia intraespecífica e interespecíficas utilizando el modelo K2P. Los valores de distancia intraespecífica oscilaron entre 0 y 0,252 %, mientras que las distancias interespecíficas fluctuaron entre 3,6 y 18,9 %, evidenciándose que esta técnica puede ser utilizada como código de barras genético en la identificación de especies de la familia Calliphoridae. Tanto en los análisis de Neighbour-Joining como en los análisis bayesianos el 90 % de los géneros presentan una monofilia sustentada en probabilidad posterior de 0,89 a 1. En todos los casos la especie Blepharicnema splendens agrupa con el género Lucilia. Con base en las secuencias obtenidas se utilizó la aplicación NEBCutter para identificar cuatro enzimas de restricción las cuales se probaron en el laboratorio y se comprobó su utilidad para la identificación rápida de especies de Calliphoridae en Colombia.

Abstract: Debido a la gran cantidad de especies y a las dificultades en su identificación morfológica, muchos estudios taxonómicos actuales de tardígrados se basan en el uso de técnicas genéticas y moleculares. En Colombia son necesarios estudios enfocados en esta disciplina que permitan complementar la información morfológica por consiguiente se analizaron siete secuencias del gen COI en el género de tardígrado Paramacrobiotus de la cuenca baja del río Manzanares, en Santa Marta, y se compararon con las secuencias del mismo género presentes en la base de datos de GenBank a través de un análisis de ergencia específica y análisis de vecino más cercano (NJ). Las secuencias obtenidas en el estudio mostraron una clara diferenciación de las secuencias de GenBank y una baja distancia intraespecífica, obteniéndose el código de barras genético correspondiente a una sola especie. Las diferencias de los resultados con el análisis morfológico reflejan la eficacia de técnicas moleculares como los códigos de barras y evidencian la importancia de la integración de técnicas moleculares a los estudios taxonómicos de los tardígrados.
