Abstract INTRODUCTION: Norway rats (Rattus norvegicus) are zoonotic reservoirs for Leptospira spp. and Toxoplasma gondii, and influence diseases in urban areas. METHODS: Free-ranging and laboratory-raised rats from two zoos in southern Brazil were tested for Leptospira spp. and T. gondii using micros...

Abstract Background and aim Brucellosis is an infectious, contagious and zoonotic disease that occurs worldwide. The family members of an index case of brucellosis may be especially susceptible, due to sharing the same source of infection and similar risk factors for brucellosis. In this study, we propo...
A cross-sectional study using 99 serum samples of dogs from southern Chile was conducted to determine the diagnostic utility of a rapid immunochromatography assay for the detection of Leptospira specific IgM antibodies as screening test and as a potential aid in the diagnosis of leptospirosis in animals ...
Abstract INTRODUCTION: Leptospirosis is an important health concern in Brazil. Currently, information on the epidemiology of the disease in the rural areas of the country is lacking. METHODS: Serological and molecular techniques were used to characterize a clinical isolate of Leptospira. RESULTS: T...

Abstract New World Nonhuman Primates are highly susceptible to clinical toxoplasmosis. Serum samples from 126 recently captured Leontopithecus chrysomelas, from an exotic and invasive population, were tested for Toxoplasma gondii antibodies by the modified agglutination test (MAT, cut-off 1:25); all were...

Abstract INTRODUCTION: Brazilian native species are reemerging as increasingly free-ranging populations. METHODS: Sera from 31 capybaras (Hydrochoerus hydrochaeris) and 28 peccaries (Pecari tajacu and Tayassu pecari) were tested for anti-Leptospira and anti-Toxoplasma gondii antibodies using microsco...

Objetivo. Evaluar si el uso del panel de 19 cepas de leptospiras, sugerido por la Sociedad Internacional de Leptospirosis para la microaglutinación (MAT, por sus siglas en inglés), permite mayor confirmación de casos que el de 12 cepas. Material y métodos. Estudio observacional de corte transversal. ...
The destruction of natural ecosystems has caused several problems to humans and other animals; herein we investigate the close relationship among vampire bats, humans and domestic animals. Toxoplasma gondii and Leptospira spp. infections are two worldwide zoonoses that provoke serious damage to animals. ...
Com o objetivo de se avaliar a freqüência de caprinos leiteiros soropositivos para Neospora caninum, no estado de São Paulo, e se verificarem possíveis associações com idade, sexo e problemas reprodutivos, nos capris, e, também, presença de cães, nas propriedades, foram obtidos soros de 923 capr...
