چکیده
An investigation concerning external and midgut bacteria associated with cockroaches isolated from household and sewage was carried out. Blood agar medium was the most suitable medium for isolation of bacteria from household species. On the other hand, several types of media such as blood agar, Littman oxgall agar, brain heart infusion in addition to nutrient agar were good media for isolation of bacteria from swage species. Bacillus and Streptococcus species recorded the highest percentage ratio between isolated bacterial from whole body and midgut of household cockroach; 38 and 36.92%, respectively. Alcaligenes faecalis, Serratia liquefaciens, Streptococcus faecalis, Streptococcus durans and Listeria seeligeri were ecological type isolated from sewage only. [Kotb M. Hammad and Hesham M. Mahdy.

Evaluation of bacterial infection of external surface and digestive system of cockroach species
Introduction: The presence of cockroaches has health implications, such as nosocomial infection, as the insects move freely from areas within and around hospitals that may harbor pathogenic organisms. The aims of the present study were to detect cockroach species and bacterial infection transmitted by their surface and their digestive system. Methods: In this study we caught 250 cockroac...
متن کاملEpidemiology and Spatial Relationships of Bacteria Associated with Periplaneta americana (Blattodea: Blattidae) in Central Texas
Identifying cockroach (Order: Blattodea) populations is important to understanding the ability of surrogate species indirectly affecting humans by their ability to vector disease-causing organisms including bacteria. These interactions may have potentially deleterious health consequences on animal and/or human populations. In this study, American cockroaches, Periplaneta americana were sampled ...

BACKGROUND Cockroaches are among the medically important pests found within the human habitations that cause serious public health problems. They may harbor a number of pathogenic bacteria on the external surface with antibiotic resistance. Hence, they are regarded as major microbial vectors. This study investigates the prevalence and antibiotic resistance of Gram-negative pathogenic bacteria s...
