Actualización de la distribución geográfica de especies de Leishmania, caracterizadas por genética molecular, en el macrofoco de leishmaniasis del Caribe colombiano.

Martínez, Lily | 2019-10-28

En Colombia existe un limitado conocimiento sobre la distribución geográfica de las especies que causan leishmaniasis, lo cual se debe a que el diagnóstico de la enfermedad y la instauración del tratamiento se basa casi exclusivamente en el examen microscópico directo, sin precisar la especie de Leishmania causal, a pesar de que existe una susceptibilidad diferencial del parásito a los medicamentos empleados. En este trabajo se actualiza la distribución geográfica de las especies de Leishmania en el norte de Colombia.

Brumptomyia hamata (Psychodidae), un nuevo aporte a la fauna flebotomínea del Caribe colombiano.

Pérez Doria, Alveiro | 2019-10-11

The sand fly fauna of the Colombian Caribbean is still not completely known and furthersurveys are needed in order to determine the richness of species over the region.Entomological samplings were performed in the municipality of Colosó, departmentof Sucre, using two modified CDC traps, in January and March of 2007. Two malesbelonging to Brumptomyia hamatawere identified. It is the first record of this sand flyspecies from the Colombian Caribbean. With the exception of the distribution of spineson the style in three distinct groups, all other morphological characters of the individualsof B. hamataagree with the original description of the species. The observed differencecould be attributed to intraspecific variation among geographic populations.

Cambios en el extremo carboxilo terminal de citocromo b como carácter taxonómico en Lutzomyia (Diptera: Psychodidae).

Vivero, Rafael José | 2019-10-16

Morphological characters have been traditionally used for identification of sand flies of the genus Lutzomyia; however, their utility is limited in some species. In this work, we characterized the mitochondrial DNA region coding for the carboxyl-terminal domain of cytochrome b protein in seven species of Lutzomyia: L. trinidadensis, L. panamensis, L. cayennensis cayennensis, L. dubitans, L. gomezi, L. rangeliana and L. evansi. A total of 134 polymorphic sites were detected in the gene (40.98%) and 29 sites in the protein (26.6%). The very high level of polymorphism observed in cytochrome b, included replacement of amino acids, use of alternative stop codons, and differences in the size of the protein. The utility of the studied region in the identification of Lutzomyia species is discussed.

Canis familiaris, un nuevo hospedero de Ornithodoros (A.) puertoricensis FOX, 1947 (Acari: Ixodida) en Colombia.

Paternina, Luis E. | 2019-10-15

Ticks are very important from the biomedical point of view, by their hematophagic activity and their role in the transmission of pathogenic microorganisms to man and animals. The main goal of this work was to establish the tick species parasiting dogs in three rural localities of the Colombian Caribbean. From August to December 2006, an active search of ticks on dogs was carried out in the localities of El Campín, Sabanas del Potrero and Escobar Arriba, department of Sucre. The collected ticks were preserved into eppendorf tubes with 70% ethanol, and identified using standard morphological keys for each family. Argasid species were determined by measuring external morphological characters. Of 134 examined dogs in the three localities, 50 were found infested by ticks, representing a infestation rate of 37,3%. A total of 420 ticks were collected from dogs and identified as Rhipicephalus sanguineus, Rhipicephalus (Boophilus) microplus, and Amblyomma ovale of the Ixodidae family, and Ornithodoros puertoricensis of the Argasidae family. R. sanguineus was the predominant species (92,1%) in the stages of larva, nymph and adult, following by O. puertoricensis larvae recorded in low numbers in the three regions sampled. The tick O. puertoricensis is recorded for the first time as ectoparasite of domestic dogs in America. Additionally, the presence of this tick species is confirmed in Colombia.

Caracteres moleculares para la determinación taxonómica de tres especies de Lutzomyia (Diptera: Psychodidae), vectores potenciales de Leishmania presentes en el valle de Aburrá, Colombia.

Pérez Doria, Alveiro | 2019-10-18

To date, 143 species of Lutzomyia França are recorded in Colombia, but less than 7% is incriminated in the transmission of Leishmania spp. Alternative taxonomic characters are necessary to correctly identify the particular sand fl y fauna in each Colombian region, and the separation of morphologically similar vector and non-vector species. In order to detect useful molecular characters for the taxonomic determination of three potential vectors of Leishmania present in the Valle de Aburrá, Colombia, the present work sequenced the 3’ end of the mitochondrial cytochrome b gene in Lutzomyia hartmanni (Fairchild and Hertig), L. columbiana (Ristorcelli and Van Ty), and L. tihuiliensis Le Pont, Torrez-Espejo and Dujardin. Polymorphic sites, pairwise genetic distances (p), and entropy were determined from the multiple alignment of the nucleotide sequences. Numbers of silent and non silent substitutions were calculated from the amino acid sequences deduced from the nucleotide sequences of the gene. In the multiple alignment of the cytochrome b nucleotide sequences from Lutzomyia hartmanni, L. columbiana and L. tihuiliensis, 83 polymorphic sites were detected. A total of 18 amino acid replacements were found in the partial nucleotide sequences of the protein. Genetic distances varied from 0,137 between L. tihuiliensis and L. columbiana, to 0,215 among L. columbiana and L. hartmanni. Nucleotide and amino acid sequence polymorphisms within the cytochrome b gene and protein, respectively, constitute molecular characters potentially useful for the taxonomic determination of these sand fl y species.

Comparación y utilidad de las regiones mitocondriales de los genes 16S y COX1 para los análisis genéticos en garrapatas (Acari: Ixodidae).

Paternina, Luis Enrique | 2019-10-01

In recent decades the analysis of mitochondrial genes has been used for population and phylogenetic studies of ticks allowing many advances in their systematics. Mitochondrial ribosomal 16S (16S) subunit is one of the most frequently used among those genes available for tick analysis, whereas cytochrome oxidase gene 1 (COX1) has recently been used and proposed as an alternative to the traditional 16S gene marker. The main objective of the present investigation is To evaluate the usefulness of 16S and COX1 in genetic studies of ticks by analyzing sequences of three species commonly found in the Caribbean region of Colombia.

Confirmación de la presencia de Lutzomyia Lutziana (Diptera: Psychodidae) en Colombia.

Bejarano, Eduar Elías | 2019-10-23

The presence of the sand fly Lutzomyia lutziana in Colombia is confirmed by one male specimen collected in the Serranía de La Macarena National Natural Park. This male was collected with a mouth aspirator, while resting in an armadillo nest. Lutzomyia lutziana resembles L. campograndensis, the former differing essentially by the slender tip of the genital filaments and the proportion of the length of the genital filaments and genital pump greater than 2,1.

Descripción de una nueva especie de Trichomyia (Diptera: Psychodidae) de los Andes Colombianos.

Bejarano, Eduar Elías | 2019-10-15

Trichomyia risaraldensis sp. nov., a new species of Psychodidae from the Colombian Andes, is described and illustrated. The type material was collected using a CDC light trap in the municipality of Marsella, department of Risaralda, Colombia. Morphologically speaking, Trichomyia risaraldensis sp. nov. resembles Trichomyia amata Barretto, Trichomyia brasiliensis Satchell, Trichomyia pseudodactylis Quate, and Trichomyia quatei Bravo, but can be distinguished from those species by traits of the head, wing and male genitalia. With the description of Trichomyia risaraldensis sp. nov., the number of Neotropical species in the genus Trichomyia is increased to 71.

Descripción del ARN de transferencia mitocondrial para Serina (UCN) de Lutzomyia columbiana (Diptera, Psychodidae).

Pérez Doria, Alveiro | 2019-10-16

Description of the mitochondrial serine transfer RNA (UCN) of Lutzomyia columbiana (Diptera, Psychodidae). The sand fly Lutzomyia columbiana is considered a suspected vector of Leishmania mexicana and Leishmania braziliensis in Colombia. Lu. columbiana belongs to the Lutzomyia verrucarum species group, which included some sibling species. This has motivated the search for molecular markers to distinguish these taxa. In this paper, we described for the first time the putative secondary structure of the mitochondrial serine transfer RNA that recognizes the codon UCN of Lu. columbiana (tRNASer). DNA was extracted, amplified and sequenced from six individuals collected in human biting activity. The secondary structure of the tRNASer was inferred using the program tRNAscan-SE 1.21. The tRNASer gene length was 67 pair of bases (pb), and a single haplotype was detected among the six specimens sequenced. In the inferred secondary structure of the tRNASer of Lu. columbiana, the acceptor arm consisted of 7 bp, the dihydrouridine (DHU) arm of 3 pb, the anticodon arm of 5 pb, and the ribothymidine-pseudouridine-cytosine (TøC) arm of 5 pb. Similarity, the estimated size of the loops was 5 nucleotides in the DHU, 7 in the anticodon, 4 in the variable, and 7 in the TøC. Lu. columbiana differs from other Lutzomyia and Phlebotomus species sequenced to date by the presence of guanine in the nucleotide position 64, which induce a non-canonical base pair conformation type uracil-guanine in the acceptor arm. More studies are necessary to confirm the usefulness of the tRNASer as a suitable molecular tool for sand fly species identification.

Description of Lutzomyia velezi, a new species of phlebotomine sand fly (Diptera: Psychodidae) from the Department of Antioquia, Colombia.

Bejarano, Eduar Elías | 2019-10-10

The phlebotomine sand fly Lutzomyia velezi sp.nov. was described and illustrated from male specimens collected by light trap in the Reserva Natural Cañon del Río Claro in the Central Cordillera of the Colombian Andes. The new species belongs to the series sanguinaria of the subgenus Helcocyrtomyia, which is represented in Colombia by Lutzomyia cirrita, Lutzomyia hartmanni, Lutzomyia sanguinaria, Lutzomyia scorzai, Lutzomyia sp. of Pichindé and Lutzomyia tortura. The new species can be differentiated from others of the subgenus by the combination of the fol- lowing characteristics: long antennal ascoids, reaching level of the papilla, coxite with a single basal seta and fifth palpomere longer than or equal to the sum of the lengths of the third and fourth palpomeres.

Detección de anticuerpos anti-leishmania (trypanosomatidae) en poblaciones caninas del departamento de Sucre, Colombia.

Paternina Tuirán, Luis Enrique | 2019-10-01

The aim of this survey was to determine prevalence of antibodies against Leishmania in dogs from Sucre, Colombia. We analyzed 122 dogs in rural areas from municipalities of Sampués, Ovejas and Sincelejo, by indirect immunofluorescence (IFA). Anti-Leishmania antibodies were detected in 69.6 % (95 % CI = 61.1 to 78.2) of the selected canine population. In the municipality of Sincelejo, Sampues and Ovejas, the seropositivities were 72 % (95 % CI = 61.1 to 82.8), 68.4 % (95 % CI = 52.3 to 84.5) and 55.5 % (95 % CI = 21.2 to 86.3) respectively. Seropositive animals were mainly young and adult dogs. The 17.6 % of seropositive dogs showed clinical signs compatible with canine leishmaniasis; onychogryphosis, alopecia and cachexia were the most common ones. The detected high frequency of canines with antibodies against Leishmania in the present study, highlights the hyperendemicity status of canine leishmaniasis in this area of the country and the high risk of disease outbreaks.
