Bovine brucellosis in dual-purpose cattle herds and its potential economic impact in the Colombian Caribbean region.

Bovine brucellosis (BB) is a cosmopolitan zoonotic disease caused by certain bacteria of the genus Brucella. It has negative health implications for the cattle, economic implications for the owners and is present in numerous cattle and wildlife populations worldwide. To determine the seroprevalence of BB in dual-purpose herds and assess its impact in the southern part of the Department of Atlántico, northern Colombia.

Trypanosoma spp. infection in urban and wild ecotopes of the caribbean region in Colombia.

Motivation for the study. The role of bats as hosts of Trypanosoma spp. in the Atlantic department in Colombia, as well as its taxonomic diversity has been poorly studied.

Phlebotomine (Diptera: Psychodidae) species and their blood meal sources in a new leishmaniasis focus in Los Montes de María, Bolívar, in northern Colombia.

Introduction. El Alférez, a village in Los Montes de María (Bolívar, Colombia) and a macro-focus of leishmaniasis, recorded its first case in 2018, evidencing changes in the distribution and eco-epidemiology of the disease, although interactions between vectors and local fauna remain unknown. Objective.

Phlebotomine sand flies (Diptera: Psychodidae, Phlebotominae): Diversity of potential Leishmania vectors in northern Colombia.

Phlebotomine sand flies are critical vectors of Leishmania parasites, impacting public health significantly. This study focused on assessing the diversity of sand flies in a rural area of El Carmen de Bolívar Municipality, northern Colombia, employing rarefaction curves and Hill numbers to understand potential vector communities and inform environmental management. From January 2018 to April 2019 (five samplings), sand flies were collected using CDC light traps with blue LED in domestic/peridomestic/sylvatic ecotopes, identifying species per Young and Duncan (1994) and Galati (2003).

Molecular survey of tick-borne infectious agents in cricetid rodents (Rodentia: Cricetidae) in Central and Southern Chile.

Tick-borne infectious agents (TBIAs) include several bacteria and protozoa that can infect vertebrates, including humans. Some of these agents can cause important diseases from both a public health perspective, such as Lyme disease, and from an animal health and production viewpoint, such as Texas fever. In Chile, several studies have assessed the presence of tick-borne disease agents in vectors and mammal hosts, mainly in the northern regions, but few studies have assessed the presence of these agents in Central and Southern Chile.

Survey and Molecular Characterization of Sarcocystidae protozoa in Wild Cricetid Rodents from Central and Southern Chile.

In Chile, studies of parasites from the family Sarcocystidae (Apicomplexa) have mostly been related to domestic animals. We aimed to assess the presence of Sarcocystidae taxa in cricetid rodents from Central and Southern Chile. We studied 207 rodents, encompassing six species, from 13 localities.

Molecular detection of the natural infection by trypanosomatid parasites in Didelphis marsupialis from a rural area in northern Colombia.

We studied the prevalence of infection by trypanosomatid parasites in Didelphis marsupialis and its relationship with morphological/age aspects in a rural area of El Carmen de Bolivar, Colombia. Five visits were made to the Vereda El Alférez; each of which lasted three consecutive nights. During these visits, Tomahawk® traps were installed in the peridomestic and wild ecotopes of the Vereda El Alférez.

Molecular diagnosis of trypanosomatids in from Los Montes de María: a first report of from Colombian Caribbean region.

is a primary reservoir of , etiologic agent of American Trypanosomiasis-AT or Chagas Disease-CD, in America. Some findings of have been recorded in this mammal, in sympatry with . In Los Montes de María, Bolívar, Colombian Caribbean, triatomine insects and potential parasite host has been registered, but little is known about the relationship between these parasites and .

Surveillance of phlebotomine fauna and Didelphis marsupialis (Didelphimorphia: Didelphidae) infection in an area highly endemic for visceral leishmaniasis in Colombia.

Introduction: The study of the interaction between the parasite, the vector and the mammalian hosts, including man, allows to understand the behavior of the leishmaniases.

Objective: To determine the presence of Lutzomyia species and to detect the Leishmania infection in Didelphis marsupialis in an endemic area for visceral leishmaniasis.

Materials And Methods: Phlebotomine fauna and individuals of D.
