Perfil de susceptibilidade a antimicrobianos de bactérias isoladas em diferentes sistemas de cultivo de tilápia-do-nilo (Oreochromis niloticus)
Provedor de dados: 45
Autores: Carneiro,D.O.; Figueiredo,H.C.P.; Pereira Júnior,D.J.; Leal,C.A.G.; Logato,P.V.R.
Caracterizaram-se as populações bacterianas isoladas de três sistemas de cultivo de tilápias, sem utilização prévia de antimicrobianos. No sistema 1 usou-se tanque de alvenaria com arraçoamento, no sistema 2, tanque de terra com arraçoamento e no sistema 3, tanque de terra com adubação orgânica. Posteriormente, foi verificado o perfil qualitativo de resistência a antimicrobianos de 98 amostras bacterianas. Membros da família Vibrionaceae predominaram nos três sistemas analisados. Observou-se elevado número de bactérias resistentes principalmente à ampicilina e à eritromicina. Bactérias resistentes à norfloxacina e à gentamicina não foram freqüentes e cerca de 50% das amostras dos isolados bacterianos foram resistentes à tetraciclina. Dentre as amostras...

Streptococcus agalactiae associado à meningoencefalite e infecção sistêmica em tilápia-do-nilo (Oreochromis niloticus) no Brasil
Provedor de dados: 45
Autores: Figueiredo,H.C.P.; Carneiro,D.O.; Faria,F.C.; Costa,G.M.
Streptococcus agalactiae was isolated from cultured tilapia in Brasil. All isolates reacted similarly in API 20 STREP system (bioMerieux, France) and Slidex strepto grouping Latex Aglutination test (bioMerieux, France). Bacterial isolates were submitted to the disc diffusion technique for the antimicrobial susceptibility test. Among nine tested drugs S. agalactiae samples were resistant to three-neomicin, nalidixic acid and gentamicin.

Passive immunity in cattle against enterotoxigenic Escherichia coli: serologic evaluation of a bacterin containing K99 and F41 fimbriae in colostrum of vaccinated females and calf serum
Provedor de dados: 45
Autores: Figueiredo,H.C.P.; Lage,A.P.; Pereira Júnior,F.N.; Leite,R.C.
A bacterin from enterotoxigenic Escherichia coli (ETEC), containing fimbriae K99 and F41, was produced and its capacity to induce anti-K99 and anti-F41 antibodies in colostrum of vaccinated cows and in calf serum, and the persistence of these antibodies in neonates were determined. Three experiments were performed on two commercial farms. In all experiments animals were allotted randomly to the blocks, each block consisting of two pregnant females (a vaccinated one and a control one) and their respective calves. In experiment A (farm 1), comprised of 18 blocks, the animals received a vaccine dose 30 days before delivery. In experiment B (farm 1), consisted of 26 blocks, the animals received two vaccine doses (60 and 30 days before delivery). In experiment...

Antibacterial activity of plant extracts from Brazil against fish pathogenic bacteria
Provedor de dados: 58
Autores: Castro,S.B.R.; Leal,C.A.G.; Freire,F.R.; Carvalho,D.A.; Oliveira,D.F.; Figueiredo,H.C.P.
The aim of this work was to evaluate the antibacterial activity of Brazilian plants extracts against fish pathogenic bacteria. Forty six methanolic extracts were screened to identify their antibacterial properties against Streptococcus agalactiae, Flavobacterium columnare and Aeromonas hydrophila. Thirty one extracts showed antibacterial activity.

Comparative analysis of conventional PCR and real-time PCR to diagnose shrimp WSD
Provedor de dados: 58
Autores: Leal,C.A.G.; Carvalho-Castro,G.A.; Cottorello,A.C.; Leite,R.C.; Figueiredo,H.C.P.
The aims of this study were to standard and optimize a qPCR protocol with FAM-BHQ1 probe, and to compare its sensitivity against TaqMan qPCR and PCR methods to diagnose shrimp WSD. The FAM-BHQ1 qPCR presented higher clinical sensitivity and showed to be a robust alternative to detect WSSV in clinical samples.
