Última Multidrug efflux systems in Gram-negative bacteria BJM Moreira,Maria Aparecida Scatamburlo; Souza,Edmar Chartone de; Moraes,Célia Alencar de. Multidrug efflux mechanisms in bacteria contribute significantly to intrinsic and acquired resistance to antimicrobial agents. Genome analysis have confirmed the broad distribution of these systems in Gram-negative as well as in Gram-positive bacteria. Among resistance mechanisms, the multidrug efflux system or pump deserves special attention, since a cell that has acquired it can simultaneously diminish or even suppress the susceptibility to a wide range of antimicrobials. The efflux system is mediated by transport proteins which confer resistance to toxic compounds. In Gram-negative bacteria, a tripartite efflux system is necessary to expel the drug to the outer medium: a protein localized in the cytoplasmic membrane; another in the periplasmatic space...

ABSTRACT: Despite the known importance of Clostridium perfringens as an enteropathogen in small ruminants, little is known about the role of its additional virulence factors or the frequency of the various C. perfringens genotypes in healthy goats; this complicates the laboratory diagnosis of the infections caused by this microorganism. In light of this, the aim of the present study was to isolate and genotype C. perfringens from stool samples from healthy goats in Brazil. Stool samples from 250 apparently healthy adult goats from 17 different herds in Minas Gerais, Brazil were collected, and isolation and genotyping of C. perfringens was performed. C. perfringens type A was isolated from 189 (75.6%) goats, whereas C. perfringens types C and D were each...

The aim of this study was to evaluate the antimicrobial effect of different copaiba oil concentrations against the growth of Listeria monocytogenes, and analyze differences in inhibition of microorganisms with autoclaved and non autoclaved oil. This study provided an agar diffusion test with six isolates of bacteria and six different concentrations of autoclaved or non autoclaved copaiba oil and a negative control. The results showed sensitivity of five L. monocytogenes isolates related to the 10% autoclaved solution of copaiba oil. Four strains also showed sensitivity to the 5% autoclaved solution and one to 2.5% autoclaved solution. The 10% non autoclaved oil solution showed growth inhibition only for two strains. These results had pointed the 10%... Tipo: Info:eu-repo/semantics/article Palavras-chave: Phytotherapics; Copaifera; Antimicrobial drugs; Listeria monocytogenes.

Tipo: Info:eu-repo/semantics/other Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-84782008000100052 Pênfigo foliáceo em um eqüino Ciência Rural Monteiro,Gabriel Augusto; Souza,Maria Verônica de; Conceição,Lissandro Gonçalves; Borba,Camila de Lacerda Balbi e Rocha; Moreira,Maria Aparecida Scatamburlo. Pênfigo foliáceo é uma rara afecção cutânea auto-imune que acomete várias espécies. Relata-se o caso de uma égua de quatro anos de idade, sem raça definida, apresentando áreas de alopecia, exsudação e crostas localizadas na face, região peitoral e membros pélvicos, além de prurido. Os exames laboratoriais para pesquisa de ácaros, bactérias e estruturas fúngicas foram negativos. O exame histopatológico revelou uma dermatite pustular intra-epidérmica com acantólise subcorneal, assim como dermatite perivascular superficial, com infiltração de eosinófilos, sendo o quadro compatível com pênfigo foliáceo.

Bacterial biofilms are involved in the aggravation and recurrence of clinical mastitis in dairy herds. Several factors such as pH, temperature, concentration of O2 and glucose can affect their induction and growth rates. In this study, biofilm production was demonstrated by 27 Escherichia coli strains isolated from bovine mastitis at different pH values depending on the availability of glucose, mimicking conditions found in mammary glands affected by the disease. Biofilm formation was analyzed by spectrophotometric analysis in microtiter plate with 16 different culture media and by scanning electron microscopy. Biofilm formation was greater in isolates cultured under conditions associated with low glucose availability (0.5% or 1.5%) and with either an...
