Vianna, Luís Carlos; Muller, Ernst Eckehardt; Freitas, Júlio César de; Pretto-Giordano, Lucienne Garcia; Salvador, Rogério; Dias, Juliana AlvesOne hundred fourteen primiparous cows wre analized. They wre from nine milk properties of the west region of São Paulo sate. On the seventh day of lactation. 42 (36.84%) showed infections in 69 (41.07%) quarters. The main aetiologic agents of the intramammary infections on the seventh day were coagulase-negative staphylococci (CMS) with 53,62%, followed by Corynebacterium spp with 26r08% and coagulase-positive ...

Alfieri, Amauri Alcindo; Silva, Caio Abércio da; Muller, Ernst Eckehardt; Freitas, Júlio César de; Reis, Antônio Carlos Faria dosWe describe the first occurrence of Swine Hemorrhagic Syndrome (SHS) in Paraná State, Brazil. Forty seven pigs, raised in an intensive production system farm were affected by SHS dying within 24 to 72 hours of starting the clinical signs. All animals presented progressive joint swollen with hemorrhagic skin and oro-nasal bleeding. Hemorrhagic lesions, located on subcutaneous and muscular tissues, were observed ...

Alfieri, Amauri Alcindo; Alfieri, Alice Fernandes; Freitas, Julio Cesar de; Silva, Caio Abercio da; Freire, Roberta Lemos; Barros, Andrea RodriguesThis work describes the etiology of a postweaning diarrhoea focus in a intensive piggery. The results of identification procedures showed the simultaneous occurrence of Escherichia coli, rotavirus, picobirnavirus and Cryptosporidium parvum. In VERO cells culture, was detected the LT (termolabile toxin) production by three E. coli samples and VT (verotoxin) production by five samples.; No presente trabalho é des...
Subclinical mastitis by Corynebacterium bovis in catle from northern Paraná, Br...
Mettifogo, Elena; Muller, Ernst Eckehardt; Freitas, Julio Cesar de; Megid, Jane; Alfieri, Amauri Alcindo; Beloti, VanerliA total of 493 hollander cows were examinated through California Mastitis Test (CMT) in the northern Paraná, for the purpose of studying the occurence of Corynebacterium bovis on subclinical bovine mastitis. Among the 225 milk samples that were positive in the CMT, the C. bovis was isolated in 58 (25,77%). The average microscopic count of somatic cells in milk samples with C. bovis was 1.032.420 cells/ml and th...

Beloti, Vanerli; Muller, Ernst Eckehardt; Megid, Jane; Rocha, Lindolfo Coelho; Mettifogo, Elena; Freitas, Julio Cesar deA total of 493 hollanders cows were examinated through California Mastitis Test (CMT) in the North region of Paraná, with target of studing the occurence of coagulase negative staphylococci on subclinical bovine mastitis. From these ones, 150 (30,4%) were positives in one or more quarters, making up a total of 225 milk samples. In 98 (43.5%) cultures, were isolated staphylococci, being 40 (40,8%) coagulase nega...
Isolamento, caracterização e susceptibilidade a antimicrobianos de estafilococo...
Muller, Ernst Eckehardt; Freitas, Julio César de; Alfieri, Amauri AlcindoForam estudadas 71 cepas de estafilococos coagulase-positivas isoladas de cães com lesões características de piodermatite. Através das diferentes provas bioquímicas utilizadas, 52(73,24%) amostras foram identificadas como S. intermedius e 19 (26,26%) como S. aureus. Todas as cepas foram testadas frente a 10 substâncias antimicrobianas, demonstrando uma acentuada resistência para a penicilina G, ampicilina, tetr...

Vidotto, Marilda Carlos; Muller, Ernst Eckehardt; Freitas, Julio César de; Alfieri, Amauri AlcindoNo presente trabalho foram estudadas 25 culturas de E.coli isoladas de leitões com diarréia, quanto a produção dos seguintes fatores de virulência: enterotoxina terlábil (LT), enterotoxina termoestável (STa) e os fatores de colonização K88 e K99. Foi testada a produção de hemolisina, colicina V e resistência a drogas antimicrobianas, além do estudo de transferência por conjugação dos plasmidios Col V, STa, Hly ...
