Abstract
Vector potential of the brown – banded cockroach Supella longipalpa (F.) (Dictyoptera – Epilampridae) for bacteria Psedomonas aeruginosa in the Laboratory Sadoon Ibrahim Ismail Faculty of Basic Education – Mustansiriyah University Summary: This research shows that the brown – banded Cockroach can transmit pathogenic bacteria Psedomonas aeruginosa in laboratory. The brown – banded cockroach Supella longipalpa (F.) was an effective mechanical transmitter of bacteria via feces. Groups of restrained brown – banded cockroaches from a laboratory colony free of Psedomonas sp. were fed graded doses of Psedomonas aeruginosa and their feces were assayed daily. The amount and duration of Psedomonas in feces is dose related with output from 1.1 × 10 to 6.4 × 104 cell / ml over a range of 3 - 20 days. The percentage of specimens excreting Psedomonas aeruginosa is also dose related and ranges from 40% with a 102 to 80% with a 106. There were no significant sex differences in excretion of Psedomonas at each dose. Introduction: Cockroach been registered with the brown – banded in Iraq in 1959 spread in recent years in different parts of Iraq (1). which appeared in homes and apartments, and government departments and hospitals. It was installed medical significance as a vector for pathogens (2, 3, 4). During cockroach living in places inhabitad by rights be a candidate being an important carrier mechanically to pathogens (5). Bacteria were isolated from cockroaches transmit diseases may not be as well (6,7). Experiments which conducted were demonstrate the possibility of this cockroaches to transfer bacteria Salmonella typhi and Staphylococcus aureus in the laboratory (6). The Possibility of moving this cockroach bacteria Psedomonas aeruginosa in the laboratory did not try despite the importance of these bacteria in the human body diseases. Note that the control of these bacteria by antibiotics. Some what difficult Psedomonas aeruginosa bacteria isolated from infected wounds (8).
