Cockroaches (Dictyoptera: Blattidae

Cockroaches (Dictyoptera: Blattidae) in the creamery profession transport microorganisms such as Escherichia coli (E. coli), Pseudomonas, Salmonella, Listeria monocytogenes and conidia of mycotoxigenic fungi. At the domestic level, there is relation between cockroach infestation and standard levels of health[1]. These synanthropic insects may play as potential vectors in the epidemiology of hospital infections, especially the transmission of drug-resistant E. coli, Pseudomonas aeruginosa (P. aeruginosa), Klebsiella spp and so on[2]. Nosocomial infection or hospital infection is acquired after the customer’s admission in the hospital and is manifested during his or her remain there or after furlough in case it is linked to hospitalization. Pursuant to the outcomes of researches, cockroaches can transport 150 bacteria species, 60 yeast species, 90 protozoa species and 45 parasite worms species[3]. Cockroaches can transport to fourteen million bacteria on the body surface and seven million in any excremental droppings[2].
Cockroaches’ excretion has compounds such as cinamic acid, xanthurenicacid and 8-hydroxyquinaldic acid (tryptophan derivatives) that have mutagenic and carcinogenic properties[3]. According to some studies, around all cockroaches collected from hospitals and human dwelling localities carried medically significant microorganisms. In a study from Morocco, the predominant bacteria on American cockroaches were Klebsiella spp., E. coli, and Enterococcus spp[4]. Fathpour et al. in a research in Iran showed that 70% of cockroaches collected from hospitals contaminated with Salmonella spp. and several of the isolates were resistant to antibacterial drugs[5]. A study in Morocco displayed that all the American cockroaches were collected to carry some species of bacteria on the body surface. The bacteria isolated from Periplaneta americana (P. americana) L. were Staphylococcus aureus, Staphylococcus epidermis, Streptococcus species, E. coli, Enterobacter spp., Klebsiella spp., Serratia spp., Proteus vulgaris (P. vulgaris), Proteus spp., Shigella spp., and Salmonella spp[6]. E. coli, P. aeruginosa, Klebsiella spp and some other possible pathogens have been isolated from cockroaches found in hospitals. Cockroaches have been related with an outbreak of dysentery[7]. In a study about the incidence of bacteria of public health interest transmitted by cockroaches in various food-related places in Spain, the presence of a number of bacteria, such as Salmonella, Enterobacter sakazakii, E. coli and Klebsiella were confirmed[8]. In an investigation in Nigeria, the bacteria isolated from American and German cockroaches captured in hospitals, human dwellings and restaurants were Salmonella spp, Shigella spp, Staphylococcus aureus, coagulase-negative Staphylococcus spp, Bacillus cereus, E. coli, P. aeruginosa, Klebsiella pneumoniae, Citrobacter freundii, Morganella morganii, P. vulgaris, Proteus mirabilis, Enterobacter cloacae and Providencia spp. The antibiotic resistant Salmonella spp. and Proteus mirabilis had multiple antibiotic resistance indexes ranging from 0.27 to 0.82[2]. The role of cockroaches as mechanical vectors of pathogens is unknown. The objective of this research was, hence, to isolate and identify the common pathogens from the American cockroaches in a hospital in Khorramshahr city, Southwestern Iran, in 2008.
