RESUMEN
Bacillus cereus pneumonia is unusual in nonimmunocompromised hosts. We describe fatal cases in 2 metalworkers and the associated investigation. Anthrax toxin genes were identified in B. cereus isolates from both patients using polymerase chain reaction. Finding anthrax toxin genes in non-Bacillus anthracis isolates has, to our knowledge, only been reported once previously.

In June 2001, an outbreak of acute gastroenteritis among 109 attendees of a church picnic in Kerr County, Texas, was reported. A 5'-nuclease PCR assay was used to screen for Salmonella in nine food items from the buffet line. Barbeque chicken B tested positive for Salmonella, and no amplification was detected in the remaining food items. These PCR findings were consistent with culture results and were confirmed by direct nucleotide sequencing. Salmonella enterica serotype Panama was cultured from both food and patient stool samples.
