Contamination of Cockroaches (Insecta: Blattaria) by Escherichia coli : A Systematic Review and Meta-analysis

BACKGROUND AND OBJECTIVESThe human intestine inhabitant and an environmental bacteria Escherichia coli (E. coli ) which can be pathogenic or nonpathogenic as the normal microflora of warm-blooded animals, including humans. E. coli is a rod-shaped, Gram-negative bacterium in the family Enterobacteriaceae. E. coli is more than harmless intestinal inhabitant, it can be highly versatile, and frequently deadly, pathogen which cause various infections like urinary tract infection, sepsis/meningitis, enteric/diarrheal disease, artherosclerosis, hemolytic uremic syndrome. Insects like cockroaches often carry microorganisms especially pathogenic organisms and their medical importance in the spread of infections cannot be ruled out. Therefore a systematic review and meta-analysis was conducted to investigate the prevalence Contamination of Cockroaches (Insecta: Blattaria) by Escherichia coli .MATERIALS AND METHODSA systematic literature search was conducted until the end of ۲۰۲۳ in electronic databases, including Web of Science, PubMed, Scopus and Embase. Data analysis was performed with the ‘metaprop program’ in STATA statistical software version ۱۱.۰ (Stata, College Station, TX, USA).RESULTS AND DISCUSSIONIn this study ۱۳۴۴ article, included the studies published for ۲۰۱۰ until now through two databases, namely, Scopus, Web of Science and PubMed identified, ۳۳ studies were included in the scoping review.CONCLUSIONThis statistical analysis indicates that the bacterial contaminants of the external cockroach body parts are potentially more harmful than from internal surfaces, and secondly, the bacterial contaminants of cockroaches in hospital environments are potentially more harmful than from other human environments. The survey indicated that the bacterial contaminant species of cockroaches appear to be mostly multiple drug resistant. The challenges of cockroaches as being potential vectors of pathogenic or opportunistic agents of human infections are discussed.
