IDENTIFICATION OF Escherichia coli AND Salmonella sp. ON SOME PLANTATION PRODUCTS

Identification of Anise (Pimpinella anisum L.) Essential Oil Compounds and Investigation of its Effect on Some Foodborne Pathogens: Bacillus cereus, Staphylococcus aureus, Escherichia coli O157: H7and Salmonella typhimurium

Background and Objectives: Nowadays, use of essential oils in food preservation is popular by researchers not only as antimicrobial agents but also as replacements for synthetic harmful preservatives. Objectives of this study were extraction and identification of Anise essential oil (AEO) compounds as well as assessment of the oil antimicrobial properties on four Gram-negative and Gram-positive...

Cloning and sequencing of ompf Salmonella typhi Salmonella ompf gene in Escherichia coli Origami

Background and Aim: Salmonella Typhi belongs to the family Enterobacteriaceae, gram-negative bacilli and causes gastrointestinal diseases such as typhoid. This bacterium has a special structure and various genes, including the ompf gene (outer membrane protein). Recent studies have shown the possibility of using ompf in the development of a diagnostic tuberculosis vaccine. Therefore, the aim of...

Identification and Purification of F11 Fimbriae on Avian Pathogenic Escherichia coli

Susceptibility of Escherichia coli, Salmonella sp. and Clostridium perfringens to organic acids and monolaurin

The antimicrobial activity of fatty acids, monolaurin, citric, succinic, fumaric, malic and lactic acid was determined in cultures of two strains of Escherichia coli, three strains of Salmonella sp. and two strains of Clostridium perfringens. Antimicrobial activity was expressed as minimum inhibitory concentration (MIC) that prevented growth and glucose utilization in treated cultures. Caprylic...

Inhibitory Effects of Lactobacillus salivarius and Lactobacillus crispatus Isolated from Chicken Gastrointestinal Tract on Salmonella enteritidis and Escherichia coli Growth

Probiotics are live cultures of microbes; often lactic acid bacteria, but also some other species, which when fed to animals, improve their health and growth through altering the intestinal microbial balance. In the present research, healthy chickens’ gastrointestinal (GI) tracts were screened for the presence of lactic acid bacteria with probiotic properties. The probiotic properties of the is...
