Díaz, Francisco J. | 2019-11-22

An important aspect of virological surveillance is the identification of the detected viruses. Broad surveillance, that typically employs deep sequencing of collected tissue samples, provides the investigator with many sequence files constructed from overlapping stretches of DNA sequences. Directed surveillance for viruses of a specific taxonomic group provides the investigator with sequence files from cDNA amplified using specific primers to conserved viral regions. Here we will describe general approaches to identify hemorrhagic viral agents through phylogenetic analysis of cDNA sequences obtained during surveillance activities.

...
Peters, Brian M. | 2019-09-24

We recently reported that a Candida albicans endosomal trafficking mutant continues to grow after treatment with the azole antifungals. Herein, we report that the vps21Δ/Δ mutant does not have a survival advantage over wild-type isolates after fluconazole treatment in a mouse model of vaginal candidiasis. Furthermore, loss of VPS21 does not synergize with established mechanisms of azole resistance, such as overexpression of efflux pumps or of Erg11p, the target enzyme of the azoles. In summary, although loss of VPS21 function enhances C. albicans survival after azole treatment in vitro, it does not seem to affect azole susceptibility in vivo.

The increasing prevalence of the asthma at world-wide level makes the investigation necessary of factors that influence their etiology and pathogenesis. In Colombia the prevalence of asthma is as high as in the industrialized countries. A study of clinical histories in the municipality of Santiago de Tolú (Colombia), showed to a high percentage of consultation by asthma and allergic rhinitis in the infantile population. With the objective to determine the frequency of asthma in the general population a descriptive study of cross-sectional was made, starting off of the information collected with a designed and proven questionnaire. A total of 316 people were asked, with representativeness of age groups and socioeconomic status. The diagnosis was confirmed by means of spirometry and measurement of the levels of total IgE in blood. As result, 8.9% of the people asked showed to clinical symptoms and positive spirometry for asthma with levels of total > IgE 100 UI/ mL, being the children between 5 and 15 years the most affected (71.5%). The survey allowed to evaluate sensitivity to environmental factors, being the house dust and smoke cigarette the most associated to the disease. The presence of mites in the accumulated dust in mattresses was confirmed, being Dermatophagoides pteronyssinusand Blomia tropicalis the most frequent species.

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.

The taxonomic identification of the Phlebotominae associated with the epidemiological cycle of leishmaniasis is based on morphological characters of the adult insect. Teratologic changes in anatomic structures of taxonomic importance may eventually induce to errors in the species identification. Herein, we described the morphologic anomalies found in three species of the subgenus Micropygomyia Barretto, 1962. Insects were collected by using suction devices in the urban area of Sincelejo, Sucre, Colombia. Five spines were observed in males of Lutzomyia cayennensis cayennensis (Floch y Abonnenc, 1941), Lu. atroclavata (Knab, 1913), and Lu. micropyga (Mangabeira, 1942), and three spines in one male of Lu. cayennensis cayennensis.

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.

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.

Aliota, Matthew T. | 2019-09-27

Zika virus (ZIKV; Flaviviridae, Flavivirus) has emerged out of Africa and caused outbreaks of febrile disease in Yap islands of the Federated states of Micronesia [1], French Polynesia [2], and Oceania; and in late 2015 Brazil reported the first known local transmission of ZIKV in the Americas [3]. The current outbreak in the Americas is cause for great concern because ZIKV appears to be spreading nearly uncontrolled with at least 24 countries and territories experiencing autochthonous spread, including Puerto Rico. Eventual local spread in the southern United States seems inevitable. Clinically, infection with ZIKV resembles dengue fever and several other arboviral diseases [4], but has been linked to neurological syndromes and congenital malformation [5,6]. Alarmingly, the rate of microcephaly (small head, reduced brain size, impaired neurocognitive development) in infants born to pregnant women has increased significantly (20-fold in 2015) in areas with high ZIKV incidence in Brazil [7]. There is increasing evidence that ZIKV infection may be causing this and other birth defects [6]; resulting in numerous CDC travel advisories and several countries recommending women delay pregnancy for up to two years. Prior to this, ZIKV existed in relative obscurity with only sporadic human infections until the end of the last century.
