Studies have revealed that natural contaminations of cockroaches can occur with many pathogens. There are approximately 40 bacteria species, almost 12 species, of parasitic helminthes. The second most common group of vertebrate pathogens. Numerous viruses, protozoa, and fungi affect humans and other vertebrate species. 1989 , Rivault et al. 1994, Baumholtz et al. 1997 , Cochran, 1999, Eggleston and Arruda 2001, Savoldelli and Luciano 2005 ). Often their movement between waste and food materials led to acquire, carry, and mechanically transfer of these pathogens. Cockroaches are suspected or proven carriers of pathogens such as dysentery and cholera. They also carry typhoid fever and other viral diseases like poliomyelitis. The parasitic worms Ascaris, Taenia and Shistosoma are also carried by cockroaches.
