Achados microbiológicos, moleculares e histopatológicos em pequenos ruminantes experimentalmente infectados com Actinobacillus seminis

Pesqui. vet. bras; 37 (7), 2017
O objetivo deste trabalho foi avaliar a patogenicidade, em ovinos, de uma cepa de Actinobacillus seminis isolada de caprino no Brasil. Foram utilizadas amostras de sêmen, punção e fragmentos de epidídimo, ducto deferente, testículos e glândulas seminíferas de dois caprinos (animais 1 e 2) e dois o...

Correlation between virulence markers of Helicobacter pylori in the oral cavity and gastric biopsies

Arq. gastroenterol; 54 (3), 2017
ABSTRACT BACKGROUND: The clinical outcome of Helicobacter pylori infection has been associated with virulence factors. The presence of these factors is useful as molecular markers in the identification of the high risk for developing severe gastric pathologies. OBJECTIVE: To correlate the presence of v...

Virulence genes and genetic relationship of L. monocytogenes isolated from human and food sources in Brazil

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT The herein presented assay provided a bacteriological and molecular characterization of 100 samples of L. monocytogenes isolated from human (43) and food (57) sources, from several regions of Brazil, and collected between 1975 and 2013. Antigenic characterization defined 49% of serotype 4b sampl...

Pathogenic Vibrio species isolated from estuarine environments (Ceará, Brazil) - antimicrobial resistance and virulence potential profiles

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT Detection of virulent strains associated with aquatic environment is a current concern for the management and control of human and animal health. Thus, Vibrio diversity was investigated in four estuaries from state of Ceará (Pacoti, Choró, Pirangi and Jaguaribe) followed by antimicrobial susce...

The virulence of Streptococcus pneumoniae partially depends on dprA

Braz. j. microbiol; 48 (2), 2017
Abstract Streptococcus pneumoniae is one of the most frequent opportunistic pathogens worldwide. DNA processing protein A (DprA) is an important factor involved in bacterial uptake and DNA integration into bacterial genome, but its role in S. pneumoniae virulence remains unclear. The aim of this study wa...

Investigations of the prevalence and virulence of Candida albicans in periodontal and endodontic lesions in diabetic and normoglycemic patients

J. appl. oral sci; 25 (3), 2017
Abstract Pulpal and periodontal tissues have similar microbiota that allows cross-contamination between the pulp and periodontal tissues. Objective The aim of this study was to investigate the prevalence of isolated Candida albicans from periodontal endodontic lesions in diabetic and normoglycemic pati...
