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.
Salmonella bacteria are rod-shaped, non spore-forming motile microbes that can be found in poultry, pigs, cows, pets, and many wild animals.There are more than 2,000 different serotypes of the bacteria, but it's Salmonella Enteritidis and Salmonella Typhimurium that cause more than 50% of human infections.Salmonella bacteria were discovered by the Theobald Smith, but named in honour of his boss Daniel Elmer Salmon.here are more than 2,000 different serotypes of the bacteria, but it's Salmonella Enteritidis and Salmonella Typhimurium that cause more than 50% of human infections.
