Novel genotype of Ehrlichia canis detected in samples of human blood bank donors in Costa Rica
(Ticks and Tick- borne Diseases, 2017-09-23)
This study focuses on the detection and identification of DNA and antibodies to Ehrlichia spp. in samples of blood bank donors in Costa Rica using molecular and serological techniques. Presence of Ehrlichia canis was ...
Brucella neotomae infection in humans, Costa Rica
(Emerging Infectious Diseases, 2017-06)
Several species of Brucella are known to be zoonotic, but B. neotomae infection has been thought to be limited to wood rats. In 2008 and 2011, however, B. neotomae was isolated from cerebrospinal fluid of 2 men with ...
Morphological and molecular characterization of the metacercaria of Paragonimus caliensis, as a separate species from P. mexicanus in Costa Rica
(Parasitology International, 2017-04)
The trematode Paragonimus mexicanus is the etiological agent of paragonimiasis, a food-borne zoonotic disease in
Latin America. This species, as well as Paragonimus caliensis, have been reported from Costa Rica, but it ...
Salmonella isolates in the introduced Asian house gecko (Hemidactylus frenatus) with emphasis on Salmonella weltevreden, in two regions in Costa Rica
(Universidad Nacional, Costa Rica, 2015-09-17)
The Asian house gecko Hemidactylus frenatus has been widely introduced in Costa Rica and tends to establish in human settlements. Some studies in other invaded countries have suggested that this gecko plays a significant ...
Persistence of Brucella abortus in the bone marrow of infected mice
(Journal of Immunology Research, 2018-12-03)
Brucellosis is a zoonotic bacterial infection that may persist for long periods causing relapses in antibiotic-treated patients. The ability of Brucella to develop chronic infections is linked to their capacity to invade ...
Salmonellosis detection and evidence of antibiotic resistance in an urban raccoon population in a highly populated area, Costa Rica
(WILEY, 2019-07-29)
Wild animals are involved in zoonotic disease transmission cycles. These are generally complex and poorly understood, especially among animals adapted to life in human ecosystems. Raccoons are reservoirs and effective ...
Brucellosis caused by the wood rat pathogen Brucella Neotomae: two case reports
(Journal of Medical Case Reports, 2017-12-19)
Background: Brucellosis is a chronic bacterial disease caused by members of the genus Brucella. Among the classical species stands Brucella neotomae, until now, a pathogen limited to wood rats. However, we have identified ...
Brucella canis is an intracellular pathogen that induces a lower proinflammatory response than smooth zoonotic counterparts
(Infection and Immunity, 2015-09-29)
Canine brucellosis caused by Brucella canis is a disease of dogs and a zoonotic risk. B. canis harbors most of the virulence determinants defined for the genus, but its pathogenic strategy remains unclear since it has not ...
Detection of antibodies against Chlamydophila abortus in Costa Rican sheep flocks
(Open Veterinary Journal, 2015-09-01)
A total of 359 sheep samples from 15 flocks were analyzed for the presence of antibodies against Chlamydophila abortus using a commercial Enzyme linked Immunosorbent Assay (ELISA). Antibodies were detected in 19 (5.29%) ...
What have we learned from brucellosis in the mouse model?
(Veterinary Research, 2012)
Brucellosis is a zoonosis caused by Brucella species. Brucellosis research in natural hosts is often precluded by
practical, economical and ethical reasons and mice are widely used. However, mice are not natural Brucella ...
