Nasal carriage of Staphylococcus aureus in healthy dairy cows in Algeria: antibiotic resistance, enterotoxin genes and biofilm formation.

Background: Staphylococcus aureus can colonize and infect a variety of animal species. In dairy herds, it is one of the leading causes of mastitis cases. The objective of this study was to characterize the S.

Phenotypic and Genotypic Characterization of Isolated from Nasal Samples of Healthy Dairy Goats in Algeria.

The present study aimed to determine the phenotypic and genotypic characteristics of . isolates from the nasal swabs of goats. A total of 232 nasal samples (one per animal) were collected from goats on 13 farms located in two regions of Algeria and were analyzed for the presence of .

Enterotoxin genes and antimicrobial resistance in Staphylococcus aureus isolated from food products in Algeria.

Aims: The aim of this study was to characterize Staphylococcusaureus isolates of food origin (dairy and meat products, pastries and sandwiches) determining the carriage in enterotoxin genes and the antimicrobial resistance pheno/genotypes.

Methods And Results: A total of 300 food samples were collected and analysed for the detection of S. aureus.

Production of clovamide and its analogues in Saccharomyces cerevisiae and Lactococcus lactis.

Clovamide and its analogues are N-hydroxycinnamoyl-L-amino acids (HAA) that exhibit antioxidant activities. For environmental and economic reasons, biological synthesis of these plant-derived metabolites has garnered interest. In this study, we exploited HDT1, a BAHD acyltransferase recently isolated from red clover, for the production of clovamide and derivatives in S.
