In an earlier report, some 19 species of bacteria were isolated from American, German and oriental cockroaches that were collected from some hospitals in Tehran while 25 various species of medically-significant bacteria were separated from American and German cockroaches in hospitals of central Tehran[15]. Despite the implication of these cockroaches in the dispersal of pathogenic bacteria to people, no data exists on the abundance and species of
bacteria carried by the cockroaches in different hospitals of Shiraz, south of Iran. The major aim of the present investigation was to identify pathogenic bacteria and their antibiotics susceptibility on and in these insects caught from two public education hospitals and a student dormitory in Shiraz.
