Coxiella burnetii associated with BVDV (Bovine Viral Diarrhea Virus), BoHV (Bovine Herpesvirus), Leptospira spp, Neospora caninum, Toxoplasma gondii and Trypanosoma vivax in reproductive disorders in cattle

Abstract This is a cross-sectional study to assess the presence of antibodies in ruminants against selected pathogens associated with reproductive disorders in cattle in four Brazilian states, including the zoonotic agent Coxiella burnetii. The used tests were Virus Neutralization Assay for IBR and BVD, ...

Risk factors associated with leptospirosis in swine in state of Pernambuco, Brazil

Arq. Inst. Biol; 86 (), 2019
Leptospirosis is a major public health threat, and swine are one of the most important reservoirs and sources of Leptospira infection for man. The aim of this study was to investigate the epidemiological situation of leptospirosis in swine in the state of Pernambuco, Brazil. Blood samples from 265 swine ...

Prevalencia de casos sospechosos de leptospirosis en pacientes reportados con diagnóstico de dengue al SIVIGILA, en el departamento de Boyacá 2016

Introducción. La leptospirosis es una zoonosis causada por bacterias del género Leptospira. En el hombre la enfermedad puede ser asintomática o cursar con un cuadro febril, hasta convertirse en una falla multisistémica, el diagnóstico diferencial se realiza con varias enfermedades, sin...

Occurrence of antibodies against Leptospira spp. in donkeys of São Paulo state

Arq. Inst. Biol; 86 (), 2019
Among the diseases that affect equines, bacterial diseases play an important role from a health and economic point of view, especially leptospirosis and brucellosis. The study aimed to provide information on the occurrence of anti-Leptospira spp. and anti-Brucella abortus antibodies in donkeys of São Pa...

Identification of pathogenic and nonpathogenic Leptospira species of Brazilian isolates by Matrix Assisted Laser Desorption/Ionization and Time Flight mass spectrometry

Braz. j. microbiol; 49 (4), 2018
ABSTRACT Matrix Assisted Laser Desorption/Ionization and Time of Flight mass spectrometry (MALDI-TOF MS) is a powerful tool for the identification of bacteria through the detection and analysis of their proteins or fragments derived from ribosomes. Slight sequence variations in conserved ribosomal protei...

Occurrence of serological reactions for serogroup Sejroe (CTG and Prajtino) in female buffalo in the state of Pernambuco, Brazil

Braz. j. microbiol; 49 (4), 2018
ABSTRACT The objective of this study was to evaluate the occurrence of anti-Leptospira spp. antibodies in female buffalo in the state of Pernambuco. A total of 123 female buffalo blood samples were collected from five properties distributed in the state of Pernambuco. The microscopic agglutination test w...

Development and validation of a modified TaqMan based real-time PCR assay targeting the lipl32 gene for detection of pathogenic Leptospira in canine urine samples

Braz. j. microbiol; 49 (3), 2018
Abstract A modified TaqMan real-time polymerase chain reaction targeting a 138 bp fragment within the lipl32 gene was developed to identify exclusively pathogenic Leptospira spp. in dog urine samples. Thirty-five samples from dogs with suspected clinical leptospirosis and 116 samples from apparently heal...

Isolation of saprophytic Leptospira spp. from a selected environmental water source of Argentina

Rev. argent. microbiol; 50 (3), 2018
Ten Leptospira spp. strains were isolated from water samples from Nievas stream, Olavarría, Buenos Aires province (Argentina). The isolates showed the typical motility and morphology of the genus Leptospira under dark field microscopy, developing in liquid EMJH medium after eight days of incubation at 1...

Efficacy of leptospiral commercial vaccines on the protection against an autochtonous strain recovered in Brazil

Braz. j. microbiol; 49 (2), 2018
Abstract In swine and bovines, leptospirosis prevention and control is carried out via vaccination of susceptible animals using bacterins. However, the efficiency of leptospirosis vaccines has been questioned. This work aimed to investigate the potency of five leptospirosis vaccines sold commercially in ...
