Prevalence and Antibiotic Resistance of Gram-Negative Pathogenic Bacteria Species Isolated from Periplaneta americana and Blattella germanica in Varanasi, India.

摘要: Background: Cockroaches are among the medically important pests found within human habitations that cause serious public health problems. They may harbor a number of pathogenic bacteria on external surface with antibiotic resistance. Hence, they regarded as major microbial vectors. This study investigates prevalence and resistance Gram-negative species isolated from Periplaneta americanaand Blattella germanica in Varanasi, India. Methods: Totally, 203 adult cockroaches were collected form 44 households 52 food-handling establishments by trapping. Bacteriological examination surfaces Pe. americana Bl. carried out using standard method antibiotics susceptibility profiles isolates determined Kirby -Bauer disc diffusion methods. Results: Among places, we 54% had cockroache infestation 77% food- handling establishments. There was no significant different between overall load (64.04%) (35.96%). However predominant Klebsiella pneumonia, Escherichia coli, Enterobacter aerogenes, Pseudomonas aeruginosa. However, Kl. pneumoniae Ps. aeruginosa most prevalent, drug-resistant strains 100% to sulfamethoxazole/ trimethoprim ampicillin. For individual bacteria, coli have multi-resistance four tested, Citrobacter freundii four, aerogenes Proteus mirabilisto three. Conclusion: uniformly distributed domestic environment, which can be possible vector for transmission food -borne diseases.
