This is when you see those high towering, popcorn looking clouds in the middle of the afternoon when the sun hits the grounds and heats the air up. Usually isolated storms do not cover a large area.
Salmonella enterica serovar Typhimurium (S. typhimurium) causes enteric disease in humans. It is a food-and water-borne pathogen that can be easily disseminated in a population: for instance outbreaks of salmonellosis can occur by contamination of salad.
There are two species of Salmonella, Salmonella bongori and Salmonella enterica. Salmonella enterica is further divided into six subspecies and over 2500 serovars.Salmonellae are found worldwide in both cold-blooded and warm-blooded animals, and in the environment.Strains of Salmonella cause illnesses such as typhoid fever, paratyphoid fever, and food poisoning (Salmonellosis).ost cases of invasive nontyphoidal salmonella infection (iNTS) are caused by S Typhimurium or S Enteritidis. A new form of Salmonella Typhimurium (ST313) emerged in the southeast of the African continent 75 years ago, followed by a second wave which came out of central Africa 18 years later.
