The objective of this study was to isolate and characterize Streptococcus spp. in Nile tilapias (Oreochromis niloticus) reared net-pens earth nurseries. Eight intensive tilapia-rearing farms were investigated north Paraná, Brazil from April 1st 2001 30th 2002. fish a system hapas nets on four nurseries other farms. A total 370 samples analyzed material collected 120 (brain, liver, kidney, skin scrapes, ascites liquid eye) that sown BHI agar (Brain Heart Infusion) supplemented with 1% yeast...
Epidemiological data describing bovine herpesvirus 1 (BoHV-1) infection in Brazilian cattle herds are scarce. A cross-sectional study was conducted the state of Paraná between December 2001 and July 2002 with objective estimating apparent prevalence BoHV-1-seropositive animals identifying potential risk factors for farms breeding Southern Brazil. The divided into seven regions based on livestock production dynamics different areas. Sampling performed two stages. Initially, were randomly...
The aim of this study was to determine the prevalence anti-Leptospira spp. antibodies and risk factors for Leptospira infection in breeding cattle herds south central region Paraná state. It based on statistic delineation/serological samples information regarding selected farms employed bovine brucellosis state context National Program Control Eradication Brucellosis Tuberculosis. A total 1.880 females aged >24 months from 274 non vaccinated were studied. Serum tested against using...
O objetivo deste estudo foi determinar a prevalência de rebanhos positivos (focos) e identificar os fatores risco que possam estar associados com infecção pelo herpesvírus bovino 1 (BoHV-1) em bovinos atividade reprodutiva, na região Oeste do Estado Paraná. delineamento estatístico, amostras soro informações referentes às propriedades foram as empregadas para o da brucelose bovina no Paraná dentro contexto Programa Nacional Controle Erradicação Brucelose Tuberculose. Foram avaliadas 1930...

This study evaluated 12 intensive breed of Nile tilapia (Oreochromis niloticus) in four properties localized the north Parana State, Brazil. In period 13 months, 71 fishes were collected and analyzed hapas nets that presenting morbidity mortality tilapias. Parallel, to evaluate quality water these nets, there was measured temperature, dissolved oxygen, pH, alkalinity, nitrite ammonia. Of fishes, 220 biological samples. 17 (23.94%) positive for Streptococcus spp. 53 samples from 24 (45.28%)...
Chlamydophila abortus é o agente etiológico do aborto epizoótico bovino, cujas manifestações clínicas mais freqüentes são aborto, nascimento de bezerros prematuros e animais fracos, natimorto repetição cio em intervalos irregulares. O objetivo deste trabalho foi estimar a prevalência anticorpos anti-Chlamydophila spp. fêmeas bovinas propriedades rurais com histórico selecionadas dentro delineamento amostral Plano Nacional Controle Erradicação da Brucelose Tuberculose no estado Paraná.

De 88 vacas primíparas, oriundas de quatro rebanhos leiteiros, foram colhidas 1985 amostras leite, ao longo dos 120 dias pós-parto, das quais 457 (23,02%) apresentaram resultados microbiológicos positivos. Os estafilococos coagulase negativos (ECN) isolados em 316 (69,14%) amostras, Corynebacterium bovis 56 (12,25%), estreptococos 41 (8,97%) e positivos (ECP) 38 (8,31%). Mastite clínica foi detectada nove (10,23%) vacas. No primeiro dia 57 (64,77%) animais 114 (32,66%) quartos exames...
Staphylococcus is one of the most frequent etiological agents bovine mastitis, causing economic losses to milk farming. This study aimed describe production and management practices in 15 herds located three microregions State Rondônia identify antimicrobial resistance profile 97 isolates genus from these herds. The were subjected susceptibility tests using agar diffusion method. Twenty-nine S. aureus selected determine their minimum inhibitory concentration (MIC). In farms studied, breeding...
Staphylococcus aureus is the main etiological agent of bovine mastitis worldwide and knowledge about its diversity virulence factors vital in controlling infections caused by this pathogen. The present study aimed to perform molecular characterization a population S. (n=153 strains isolated from 1994 2014 seven Brazilian states) pulsed-field gel electrophoresis (PFGE) evaluate their profiles via polymerase chain reaction (PCR). PFGE identified 93 pulsotypes, with isolates organized into 26...

Bacterial count (SPC) and somatic cell (SCC) are considered universal indicators of milk quality. The objective this study was to identify SPC SCC clusters in samples from three microregions the state Rondônia evaluate influence year period tank type on these indicators. A total 566 cooling tanks linked dairy industries with Federal Inspection Service located Ariquemes, Ji-Paraná Porto Velho were evaluated. results geographical coordinates obtained industry database; focused official...
Two hundred primiparae cows from 12 milk properties in the west region of São Paulo state and north Paraná state, were studied. About animals studied, 86 (43%), showed infections 140 (17,56%) quarters on seventh day after parturition. On first 150 days lactation, 2372 samples achived. them, 504 (21,24%) positive according to bacteriological test. From 14th lactations on, microorganisms isolated more often, coagulase negative staphilococci (CNS) 213 (13,52%) samples, Corynebacterium spp 97...
