Botulismo em bovinos resulta da ingestão de toxina previamente formada. No presente trabalho são descritos sete surtos intoxicação onde os dados clínico-patológicos, epidemiológicos e achados laboratoriais indicaram a possível através água contaminada. O coeficiente médio mortalidade foi 20,1%, com letalidade 99,92%, morbidade 31,62%. Dos cerca 9.000 envolvidos nos surtos, 2.844 morreram quadro clínico predominantemente superagudo agudo. A alta foram registradas num curto período tempo...

Surtos de botulismo causados pelos tipos C e D da toxina botulínica são freqüentes no país, estando originalmente associados à osteofagia ingestão alimentos água contaminados. No presente trabalho descritos os aspectos epidemiológicos, clínico-patológicos laboratoriais sete surtos intoxicação em bovinos corte leite alimentados com cama frango, ocorridos nos estados São Paulo Minas Gerais entre 1989 2000. Cinco ocorreram rebanhos confinados ou criados extensivamente suplementados o...

Abstract Effects of fibrinogen binding to M protein‐positive and ‐negative streptococci on fixation the third component human complement (C3) were determined. In all test cultures serological groups A, B, C, G C3 was observed in normal serum as revealed by quantitative fluorescent immunoassay. Fibrinogen inhibited streptococci. The degree inhibition proportional extent binding. Thus, most pronounced strongly fibrinogen‐positive not demonstrable fibrinogen‐negative C G. Trypsinization...

Abstratc: Bovine periodontitis is a progressive purulent infectious process associated with the presence of strictly and facultative anaerobic subgingival biofilm epidemiologically related to soil management in large geographic areas Brazil. This study aimed detect species genera Porphyromonas Prevotella, which occurr periodontal pockets cattle lesions deeper than 5mm (n=26) gingival sulcus animals considered periodontally healthy (n=25).

ABSTRACT: This study aimed to review cases of blackleg (Clostridium chauvoei infection) diagnosed in cattle from Midwestern Brazil 1994 2014 considering epidemiological, clinical, necropsy and histopathological findings. Also the following laboratory tests were used for diagnosis some blackleg: microbiological culture identification agent, agent by polymerase chain reaction (PCR), formalin fixed paraffin embedded tissues (FFPE). Criteria presumptive included necrohemorrhagic emphysematous...

Introduction. Periodontitis, one of the most common oral disorders in sheep, is caused by a mixed and opportunistic microbiota that severely affects health welfare animals. However, little known about ecological processes involved composition associated with development disease. Hypothesis/Gap Statement. Using high-throughput sequencing 16S ribosomal RNA gene network analysis it would be possible to discriminate microbiomes clinically healthy sheep those periodontitis possibly identify key...

Periodontitis in cattle is an infectious purulent progressive disease associated with strict anaerobic subgingival biofilm and epidemiologically related to soil management at several locations of Brazil. This study aimed detect Treponema species periodontal pockets lesions deeper than 5mm the gingival sulcus 6 24-month-old animals considered periodontally healthy. We used paper cones collect materials, after removal supragingival plaques, kept frozen (at -80°C) up DNA extraction polymerase...

O diagnóstico da intoxicação nos animais foi baseado nas características clínico-patológicas, epidemiológicas ou laboratoriais. Dos evolução clínica crônica botulismo, cujos foram três pela tipo D, um complexo CD dos negativo na...

The serological response of beef calves was evaluated with different vaccination regimens against blackleg, using an official strain (MT) and a field-collected Clostridium chauvoei as antigens. Sixty were randomly allocated to four groups submitted distinct protocols commercial polyvalent vaccine. Group G1 first vaccinated at months age booster shot given after weaning, eight months. G2 the dose 30 days later. G3 only once control group not vaccinated. These alternative proposed in effort...

ABSTRACT: Periodontal diseases are multifactorial infectious processes caused by complexes of microorganisms, with damage to health, production, and animal welfare. The aim the present study was evaluate efficacy virginiamycin in prevention control two early forms periodontal disease: gingivitis necrotizing gingivitis. Ten weaned calves, aged four six months, were permanently kept a single lot under same rotational grazing regime newly reformed area Panicum maximum. Five calves orally...
