Interactions of organic acids with Staphylococcus aureus and MRSA strains from swine mandibular lymph node tissue, commercial pork sausage meat and feces Staphylococcus aureus is a Gram-positive bacterium affecting human health, and a major cause of skin infections. Methicillin-resistant S. aureus (MRSA) is a worldwide health concern and occurs in food animals. mproved strategies are needed to ensure disinfection of MRSA. A total of 164 S. aureus ... Growth Kinetics of Staphylococcus aureus and Background Microorganisms in Camel Milk Staphylococcus aureus is a common foodborne pathogen that is ubiquitous in nature. Consumption of contaminated foods, such as dairy products, can lead to food poisoning caused by heat-stable staphylococcal toxins not easily destroyed during pasteurization. The objective of this study was to investig... Characterization of a persistent, treatment-resistant, Staphylococcus aureus infection causing chronic mastitis in a Holstein dairy cow We describe a case of naturally occurring, chronic mastitis in a Holstein cow (1428), caused by a strain of Staphylococcus aureus (S. aureus). The infection was identified in a left hind quarter two months into the cow’s first lactation and persisted for the following 20 months, including through dr... Genome sequence of a chronic Staphylococcus aureus isolated from a dairy cow that was non-responsive to antibiotic treatment Staphylococcus aureus is a major pathogen that can cause mastitis in dairy cattle.
