Cutaneous Leishmaniasis in dogs: Is high seroprevalence indicative of a reservoir role?
(Cambridge University Press, 2015-05-20)American cutaneous leishmaniasis (ACL) is a complex disease with a rich diversity of animal host species. This diversity imposes a challenge, since understanding ACL transmission requires the adequate identification of ... -
Cutaneous Leishmaniasis and sand fly fluctuations are associated with El Niño in Panamá
(PLOS ONE, 2014-10)Cutaneous Leishmaniasis (CL) is a neglected tropical vector-borne disease. Sand fly vectors (SF) and Leishmania spp parasites are sensitive to changes in weather conditions, rendering disease transmission susceptible to ... -
Counts, serovars, and antimicrobial resistance phenotypes of salmonella on raw chicken meat at retail in Colombia
(International Association for Food Protection, 2013-10-21)The objective of this study was to determine Salmonella counts, serovars, and antimicrobial-resistant phenotypes on retail raw chicken carcasses in Colombia. A total of 301 chicken carcasses were collected from six ... -
Comparison of the antibody response in adult cattle against different epitopes of Brucella abortus lipopolysaccharide
(Blackwell, 2001)The comparison of serological responses in a sample of adult, vaccinated and held-infected bovines with Brucella abortus is reported. Indirect enzyme immunoassav (EIA) titration curves and Western blotting tests for ... -
Flora bacteriana cloacal y nasal de Lepidochelys olivacea (Testudines: Cheloniidae) en el pacífico norte de Costa Rica
(Universidad de Costa Rica, 2005-07-05)The aerobic cloacal and nasal bacterial flora of 45 apparently healthy female olive ridley sea turtles (Lepidochelys olivacea) was studied at Nancite nesting beach, in Santa Rosa National Park (Costa Rican North Pacific) ... -
Clinical and pathological findings of a sac-like formation in the tunica vaginalis of a nelore (Bos indicus) bull
(Blackwell, 2010)Contents A seven-month-old purebred Nelore calf was diagnosed with a bilateral finger-shaped swelling although more prominent at the left side of the scrotum, located longitudinal and parallel to epididymis corpus. The ... -
Climatic variability and landscape heterogeneity impact urban mosquito diversity and vector abundance and infection
(Ecosphere, 2011-06-23)Urban habitat heterogeneity can modify interactions across species and lead to spatially fine grained differences in b-diversity patterns and their associated ecosystem services. Here, we study the impacts of landscape ... -
Climatic fuctuations and malaria transmission dynamics, prior to elimination, in Guna Yala, República de Panamá
(BioMed Central, 2018-02-20)Background: Malaria has historically been entrenched in indigenous populations of the República de Panamá. This scenario occurs despite the fact that successful methods for malaria elimination were developed during the ... -
Childhood leukaemia in Costa Rica, 1981-96
(Blackwell Science, 2002)Childhood leukaemia incidence in Costa Rica during 1981-96, among the highest in the world, was analysed by histology, gender, birth year, time period of diagnosis, age at diagnosis and region. Numbers of cases were extracted ... -
Characterization of Brucella abortus lipopolysaccharide macrodomains as mega rafts
(Blackwell Science, 2005-09-28)The lipopolysaccharides (LPS) of intracellular Proteobacteria such as Brucella, Chlamydia, Legionella and Rickettsia, have properties distinct from enterobacterial LPSs. These properties include deficient LPS induction of ... -
Characterization of Brucella abortus and Brucella melitensis native haptens as outer membrane O-type polysaccharides independent from the smooth lipopolysaccharide
(American Society for Microbiology, 1996)Brucella native haptens (NHs) extracted with hot water from smooth (S)- type B. abortus and B. melitensis were purified to high levels of serological activity and compared with the polysaccharide obtained by acid hydrolysis ... -
Characterization of a recent malaria outbreak in the autonomous indigenous region of Guna Yala, Panama
(BioMed Central, 2015-11-17)Background: This study aims to describe the epidemiological and entomological factors associated with a recent malaria outbreak that occurred in 2012 in a socially marginalized population from Guna Yala Comarca in Panama. ... -
Changes in Phlebotomine Sand Fly Species Composition Following Insecticide Thermal Fogging in a Rural Setting of Western Panamá
(PLOS ONE, 2013-01-09)American Cutaneous Leishmaniasis, ACL, is a zoonotic disease with a large richness of co-occurring vector species in transmission foci. Here, we describe changes in patterns of phlebotomine sand fly (Diptera: Psychodidae: ... -
Chagas' disease: Risk factors for house infestation by Triatoma dimidiata, the major vector of Trypanosoma cruzi in Costa Rica
(The Johns Hopkins University School of Hygiene and Public Health., 1991)The reduction of domiciliary infestation by insect vectors, the key to controlling Chagas' disease, depends on identification of housing features associated with infestation. In this study, log-linear modeling was used to ... -
Chagas disease in dogs from endemic areas of Costa Rica
(Memórias do Instituto Oswaldo Cruz, 2002-06)Dogs with the presumptive diagnosis of Chagas disease are commonly sent to our School of Veterinary Medicine by independent veterinarians. This prompted us to evaluate the prevalence of canine trypanosomiasis in some ... -
Canine mycotic keratoconjuntivitis caused by Acremonium kiliense
(Oxford University Press, 1985)Mycotic keratoconjuntivitis caused by Acremonium kiliense in a German Shepherd bitch was diagnosed with the aid of laboratory tests. The dog presented with photophobia, tearing, corneal edema and reduction of the visual ... -
