Brazilian scientists have identified a new strain of the H1N1 virus after examining samples from a patient in Sao Paulo, their institute The variant has been called A/Sao Paulo/1454/H1N1 by the Adolfo Lutz Bacteriological Institute, which compared it with samples of the A(H1N1) swine flu from California. The genetic sequence of the new sub-type of the H1N1 virus was isolated by a virology team lead by one of its researchers, Terezinha Maria de Paiva, the institute said in a statement. The mutation comprised of alterations in the Hemagglutinin protein which allows the virus to infect new hosts, it said. It was not yet known whether the new strain was more aggressive than the current A(H1N1) virus which has been declared pandemic by the World Health Organization. The genetic make-up of the H1N1 virus and its subvariants are important for scientists.

Salmonella with its having garnered much media attention due to the outbreak involving peanut butter is a food borne illness. It is contracted by the ingestion of the salmonella bacteria. While often linked to poultry and poultry byproducts like eggs, salmonella bacteria can infect any food source as proven with the recent peanut butter outbreak. Other fairly recent cases of salmonella infestations have been linked to jalapeo peppers, cereal items, and tomatoes. Food can become infected with salmonella bacteria in several ways. Causes of salmonella infection include food sources contaminated by feces of animal or human nature, cross contamination, contamination by water tainted with the bacteria, and poor food handling procedures. Humans that have been infected at one time with salmonella bacteria tend to be carriers of it. It is especially important that these individuals take extra care to prevent passing along salmonella to others. The likeliness of passing the bacteria can be lesse..... Read more
