The use of biodiverse autochthonous natural starter cultures to produce typical and PDO cheeses contributes establishing a link between products territory production, which commercial starters, constituted by few species strains, are not able to. purpose this work was the assessment biodiversity, at strain level, safety scotta-innesto whose is mandatory for Pecorino Romano cheese manufacturing,...

The incidence of Lactococcosis caused by Lactococcus garvieae, in rainbow trout (Oncorhynchus mykiss, Walbaum, 1792) farms is disquieting and increasing in recent years. Knowledge of biotypes and serotypes involved in disease incidence is essential to adopt disease prevention and control policies. Twelve isolates of L. garvieae from some rainbow trout farms were identified by phenotypic, bioche...

Dissemination of Acinetobacter baumannii strains in different units of a hospital in Sorocaba, São Paulo, Brazil was evaluated over a period of two years. By using biotyping, serotyping and ribotyping, 27 distinct clones were differentiated among 76 strains isolated between 1993-94, from clinical specimens of hospitalized patients. Two clones, 2:O4:A (biotype:serotype:ribotype) and 2:O29:A acco...

A set of 103 epidemiologically well-defined Acinetobacter baumannii isolates obtained from nine hospital outbreaks and 21 unrelated strains were characterized by pulsed-field gel electrophoresis (PFGE) of total genomic DNA digested with ApaI. Among outbreak strains, eight different patterns and five possible variants were identified by PFGE. Results were compared with those from traditional typ...

Rectal swabs (feacal) samples were collected from 518 sheep across Sokoto state and processed for Campylobacter organisms. Of a total of 518 samples, 93(18.0%) yielded Campylobacter organisms. The Campylobacter species isolated in this study were Campylobacter jejuni, Campylobacter coli, Campylobacter lari and Campylobacter upsaliensis. The most frequently isolated Campylobacter species was C. ...

Staphylococcal enterotoxins (SEs) are exoproteins which, when produced in food that is then ingested by humans, give rise to symptoms of acute gastroenteritis [2]. Several types of staphylococcal enterotoxins have been identified on a serological basis and are named SE A through U (SEA through SEU) with SEA to SEE being the most frequently encountered due to there detection by usual standard ki...

To simplify the selection of tests for bacteriological typing methods, such as bacteriophage, bacteriocin, and biotyping, a computerised method was assessed. This uses a numerical index of discrimination (D) to facilitate the selection of an efficient typing set. The computer programs take the most discriminatory test as the initial test in the partial typing set, and then select the next test ...
