ABSTRACT

A total of (107) swab samples, (54) from kitchen sinks, and (53) from laundry machines were obtained from houses in the city of Mosul. Samples were analyzed for the presence of Mesophilic aerobic bacteria, Pseudomonas, Staphylococci, and enterobacteriaceae. Results showed that 94.4 % of sink samples were contaminated with one or more microorganisms. Pseudomonas and Klebsiella were the two dominant bacteria  (39%, 23.4%, consequently) in addition to coagulase negative micrococcaceae, E.coli, Citrobacter, Enterobacter, Proteus and Salmonella.

Also, 69% of laundry machines were contaminated mostly with pseudomonas (40%) , and coagulase negative micrococcaceae (31.9%) , in addition to Enterobacter and Citrobacter. The effectiveness of six disinfectants (available in local markets), Lenol, Fentol, Aredol Hexavlon,, Chloroxylenol, and Na-hypochlorite (housebleach) were evaluated against Pseudomonas aeroginosa and Klebsiella (from the isolates above). Both bacterial species were inhibited by four out of six products namely, Fentol, Hexavlon, Chloroxylenol, Na-hypochlorite immediately upon addition of disinfectants. The most effective product was Chloroxylenol , followed by Na-hypochlorite.
