The pathogenesis of a Streptococcus agalactiae was evaluated in three-period experiment. Two groups 40 fishes were intraperitoneally (i.p.) challenged each experimental period with different infective doses the pathogen. Doses varied from 1.0 x 10(6) to 1.5 10(8) CFU/fish. One group tilapia i.p. injected tryptic soy broth (TSB) used as control period. Mortalities 67.5% 8 (infective dose CFU/fish) 90.0% 1 CFU/fish). Significant differences mortalities found only between and other groups,...
The etiology and pathologic findings of bovine respiratory disease (BRD) in adult dairy cows (n = 35) from a commercial herd Southern Brazil were investigated. Pulmonary samples examined for histopathologic patterns specific features within these patterns, while immunohistochemical (IHC) assays designed to detect the intralesional antigens viral infectious agents Mycoplasma bovis. Pneumonia was diagnosed 91.4% (32/35) cases; neither pneumonia nor any pathogens evaluated occurred three cows....
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...
Streptococcus agalactiae is a major causative agent of streptococcosis in Nile tilapia (Oreochromis niloticus) and understanding its etiology important to ensure the sustainable development global farming. Our research group recently observed contrasting disease patterns animals infected with two different S. serotypes (Ib III). To better understand basis for these divergent responses, we analyzed brain transcriptome following bacterial exposure. findings revealed significant variation...
Tilapia aquaculture is one of the fastest-growing segments fish production in Brazil. Nile tilapia (Oreochromis niloticus) largely cultivated state Parana, where Streptococcus agalactiae cause severe disease outbreaks. The objective this paper was to evaluate an inactivated S. vaccine for control streptococcal Tilapia, weighing approximately 20 g each, were intraperitoneally (i.p.) inoculated with 0.1 mL at a dose 2.0 × 108 colony-forming unit (CFU) mL−1. One group (treatment 1) received...
The pyometra is a disease that affects middle age and elderly female dogs during diestrus. Hormonal, microbiological, biochemical hematological aspects are well described. However, few studies have evaluated the role of each in prognosis canine pyometra. aim this study was to identify markers associated with clinical worsening We prospectively 80 treated surgically. Group 1 consisted were discharged within 48 hours after surgery 2 those who required prolonged hospitalization or died....
Although leptospirosis has been considered a major concern in urban areas, no study to date spatially and simultaneously compared both owner dog serology households of cities. Accordingly, the aim present was assess seroprevalence Leptospira antibodies, evaluate associated risk factors conduct spatial analyses 565 randomly selected households, which included 597 owners 729 dogs Londrina, Southern Brazil. Seropositivity by MAT were detected 11/597 (1.84%) 155/729 (21.26%) dogs. The evaluated...
The bovine respiratory disease (BRD) complex is a multietiological and multifactorial associated with wide range of viral bacterial pathogens. This study evaluated the contribution specific infectious agents in development BRD cattle from Brazil determined if virus within malignant catarrhal fever (MCFV) group
Abstract This study evaluated the seroprevalence of Toxoplasma gondii, Neospora caninum and Leptospira spp. in dogs from Foz do Iguaçu, Paraná, Brazil. Indirect immunofluorescent antibody test was used to detect antibodies anti-T.gondii anti-N. caninum. Immunoenzymatic assay microscopic serum agglutination were for screening anti-Leptospira spp., respectively. The results were: 67.02% samples reactive T.gondii 1.38% N. caninum, both without statistically significant variables. For indicated...
A mastite em ovelhas da raça Santa Inês apresenta-se como um problema de grande proporção e gravidade é dificilmente tratada com sucesso. O objetivo deste estudo foi caracterizar aspectos clínicos, epidemiológicos etiológicos clínica corte criadas no norte do Paraná. presente realizado entre os meses outubro 2009 a setembro 2010 envolvendo 54 rebanhos ovinos diferentes raças. Durante as visitas às propriedades, questionário preenchido finalidade o problema. Setenta foram examinadas amostras...
This study investigated the occurrence of selected pathogens bovine respiratory disease in fetal pulmonary tissue cattle and associated these with patterns disease. Fetal (n = 37) tissues were evaluated by histopathology; immunohistochemical assays identified intralesional antigens alphaherpesvirus 1 (BoAHV1), viral diarrhea virus (BVDV), parainfluenza 3 (BPIV-3), syncytial (BRSV), Mycoplasma bovis. Molecular performed to amplify reproductive gammaherpesvirus 6 (BoGHV6) from 12 lungs. The 2...
Resumo Piometra é uma afecção resultante da interação bacteriana com a hiperplasia cística do endométrio. O objetivo deste estudo foi identificar bactérias em condições de aerobiose e anaerobiose secreção intrauterina cadelas piometra, presença síndrome resposta inflamatória sistêmica, status cérvix, peritonite, dosagens bioquímicas séricas comparar o prognóstico tratadas cirurgicamente. Utilizaram-se 15 submetidas à ovariohisterectomia. Hemogramas ureia, creatinina, FA ALT foram realizados...
Streptococcus agalactiae, also known as Group B (GBS), is a Gram-positive bacterium that colonizes the gastrointestinal and genitourinary tract of humans. This has been isolated from various animals, such fish cattle. Non-coding RNAs (ncRNAs) can act regulators gene expression in bacteria, pneumoniae pyogenes. However, little about genomic distribution ncRNAs RNA families S. agalactiae. Comparative genome analysis 27 agalactiae strains showed more than 5 thousand regions identified...
The current paper contains a report on the isolation of Streptococcus iniae in Nile tilapia (Oreochromis niloticus) Brazil and South America.S. is an important pathogen often associated with significant losses fish production.It also known for causing invasive infections humans.An outbreak characterized by exophthalmos, erratic swimming, ascites melanosis occurred intensive farming.Samples kidney, brain liver seeded into culture medium yielded beta-hemolytic, gram-positive cocci isolate from...
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...
