Phlebotomine sand flies, vectors of leishmaniasis, have not been well studied in the Sierra Nevada de Santa Marta, and likewise, are not well known in other regions of the Department of Magdalena, Colombia. To date only thirteen species of Lutzomyia have been recorded as occurring in the Department. The present note adds three species and includes an additional subgenus. Collections were made in the lower foothills of the Sierra Nevada de Santa Marta at elevations ranging from 117–130 m in the communities of Seywiaka, Las Tinajas and Calabazo. Eighty-four percent of the 885 phlebotomines sand flies collected were obtained from CDC light traps, 11 % from Shannon trap and 5 % from typical resting sites using an electric aspirator. The following nine species were identified from the collections: Lutzomyia gomezi, Lu. panamensis, Lu. trinidadensis, Lu. carpenteri, Lu. evansi, Lu. dysponeta, Lu. dubitans, Lu. shannoni, and Lu. micropyga. The most abundant species were Lu. gomezi and Lu. panamensis, which, respectively, accounted for 69 % and 14 % of the specimens. Of the nine species, Lu. carpenteri, Lu. dubitans and Lu. dysponeta represent new records for the Department of Magdalena. Also, a few female specimens were encountered of a species belonging to the Lu. osornoi series of the subgenus Helcocyrtomyia, which represents the first record of this subgenus in the Caribbean region of Colombia.

Vivero, Rafael José | 2019-10-11

This is the first report of Lutzomyia longipalpis (Lutz & Neiva, 1912), L. shannoni (Dyar, 1929), L. micropyga (Mangabeira, 1942) and L. atroclavata (Knab, 1913) in the surroundings of an urban settlement in the Caribbean coast. Phlebotomine sandflies were collected by active search using suction devices and mouth aspirators in trees around the city of Sincelejo, the capital of the department of Sucre. Epidemiological importance derived from this finding is discussed due to the vectorial capacity of L. longipalpis, the natural vector of Leishmania infantum Nicolle, 1908 in America.

Phylogenetics of South American Biomphalaria and description of a new species (Gastropoda: Planorbidae).
...
Estrada, Victoria E. | 2019-10-24

The planorbid snail Biomphalaria edisoni n. sp. is described from morphological and molecular characters, based on specimens collected at two localities in Colombia. The new species has the typical features of the genus, as well as the following characteristics: vaginal pouch, numerous prostatic diverticular arranged in racemes, penis sheath/prepuce ratio of approximately 2 and a penial complex half the length of the cephalic portion of the female duct. These elements differentiate it from B. kuhniana, which was also present in one of the localities, and also from B. prona,B. helophila and B. nicaraguana, with which it has greater morphological similarities. Phylogenetic analysis of the nucleotide sequences of the internal spacers of the ribosomal DNA transcript (ITS1, ITS2) of B. edisoni n. sp. and 14 neotro-pical Biomphalaria species indicates that the former belongs to the monophyletic group including B. prona and B. sp. from Cuba. The genetic distances within this monophyletic group are however great enough for B. edisoni n. sp. to be regarded as a separate species. Thus morphology, phylogenetic tree topology and genetic distances all support the recognition of B. edisoni as a new species.

Predicción de la estructura secundaria del tRNASer (UCN) mitocondrial del flebotomíneo Lutzomyia hartmani (Diptera: Psychodidae).
...
Pérez Doria, Alveiro | 2019-10-09

Lutzomyia (Helcocyrtomyia) hartmanni is a sand fly that has been implicated in the transmission of Leishmania (Viannia) colombiensis, an etiologic agent of cutaneous leishmaniasis in Colombia. The objective of this work was to explore the potential usefulness of the mitochondrial serine transfer RNA (UCN) (tRNASer) in the taxonomic determination of L. hartmanni. Mitochondrial DNA was extracted, amplified and sequenced from entomological material collected in Envigado, Antioquia, Colombia. The tRNASer gene length was 68 nucleotide pairs, with an average adenine-thymine content of 80,9%. The studied tRNASer differs from other sand fly tRNASer known to date, on the basis of its primary and secondary structure. The observed number of intrachain base pairing was 7 in the acceptor arm, 3 in the dihydrouridine (DHU) arm, 5 in the anticodon arm, and 5 in the ribothymidine-pseudouridine-cytosine (T C) arm. The size of the DHU, anticodon, variable and T C loops was estimated to be 5, 7, 4, and 8 nucleotides, respectively. The notorious absence of non-Watson-Crick base pairs in the four arms of the tRNASer distinguishes that of L. hartmanni from others Lutzomyia spp.

...
Victoria, Robin Jesús | 2019-09-24

Leptospirosis is one of the most frequent zoonoses worldwide and occurs in tropical, subtropical and temperate areas. The genus Leptospira comprises saprophytic and pathogenic species. The latter isolated from several animals that serve as reservoirs and carriers. The presence of bats in urban areas has increased for various reasons, profusion of plants, lack of predators, presence of luminaries, which has increased the chances of contact between bats, humans and/or pets. The aim of this work was to investigate the presence of pathogenic Leptospira in bats captured in the city of Sincelejo, using the molecular PCR technique. Mist nets were used to capture the bats and these were sacrificed using ether to obtain samples of renal tissue. A fragment of the LipL32 gene was amplified by PCR technique. We identified three families of bats amongst our sample and 26% of them presented pathogenic Leptospira DNA. This represents a great risk to the community in this region.

Bejarano, Eduar Elias | 2019-10-31

American visceral leishmaniasis (AVL) is a potentially fatal disease of neotropical countries, chiefly affecting children aged under 5 years, caused by ~ishmania (Leishmanial &a& Cunha & Chapas. which is indisiinguishablk from the ‘Old World’ paiasite Le. (Le.) injuntum Nicolle, of which it may be a synonym. AVL is transmitted to human or other mammalian hosts by the bites of the phlebotomine sandflies Lutzanzyia (Lutzomy&z) Zongt$alpis (Lutz & Neiva) or Lmmnyiu (Lutzomyia) evami (Nufiez-Tovar) (GRIMALDI et al., 1989; TRAVI et al., 1996). Although Lu. longipalpis is the most widespread and important vector of AVL, Lu. evarnsi has been confirmed as a primary vector in rural areas of the Caribbean coast of Colombia and in some areas of Venezuela (AGUIUR et aE., 1995; MONTOYA, 1996; FEIJCLWGELI et al., 19991. While conducting entomological studies in the urbad area of Sincelejo &y (9’ 18’ N. 75” 25’ WI in northern Colombia. we found adults of Lzk. eeransi ih houses and in peridbmiciliary environments. This is the first record of Lu. evansi from an urban area in Colombia.

Studies of the insects associated with the epidemiological cycle of leishmaniasis on the Caribbean coast of Colombia have been focused on the departments of Sucre and Córdoba. The phlebotomine sand fly fauna of the rest of the Caribbean region remains little known. In the present study four species of the genus Lutzomyia are reported from the department of Cesar for the first time. Sand flies were sampled using two CDC light traps with blue color LEDs at Balneario Hurtado, a tourist area in the city of Valledupar. A total of 50 phlebotomine sand flies were collected, of which the species Lutzomyia cayennensis cayennensis (38 % of the sample) and L. trinidadensis (14 %) were already known from the departament. Specimens of L. evansi (28 %), L. venezuelensis (10 %), L. micropyga (6 %) and L. rangeliana (2 %) represent the first records of these species for Cesar, raising the number of known occurrences from the department to eight species. Noteworthy among the new records is the sandfly L. evansi, recognized vector de Leishmania spp. in the Colombian Caribbean coast.

Sampling Design and Mosquito Trapping For Surveillance of Arboviral Activity.
...
Paternina, Luís E. | 2019-11-22

Mosquitoes are the most important vectors for arboviral human diseases across the world. Diseases such as Dengue Fever (DF), West Nile Virus (WNV), Yellow Fever (YF), Japanese Encephalitis (JE), Venezuelan Equine Encephalitis (VEE), and St. Louis Encephalitis (SLE), among others, have a deep impact in public health. Usually mosquitoes acquire the arboviral infection when they feed on viremic animals (birds or mammals), so their infection can be detected along the year or in short periods of time (seasons). All of this depends on the frequency and seasonality of the encounters between viremic animals and vectors. With the convergence of several phenomena like the increasing traveling of human populations, globalization of economy and more recently the global warming, the introduction of nonendemic arbovirus into new areas has become the current scenario. As examples of this new social and environmental frame we can mention the outbreak of West Nile Virus in North America in the late 1990s and more recently the outbreaks of chikungunya and Zika virus in the Americas. The present chapter deals with one of the first steps in the development of research studies and diagnosis programs, the surveillance of arboviruses in their vectors, the sampling design and mosquito trapping methods. The chapter also includes some important considerations and tips to be taken into account during the mosquito fieldwork.
