Introduction: Hospital laundry are potential reservoirs of bacteria in hospitals. Preventing contamination and providing clean linen and laundry should help to prevent hospital acquired infections. Being an important component in the management of patients and the role in causing hospital acquired infections, the study about hospital laundry has been undertaken in our hospital. Methods: Quality control practiced in the Linen and Laundry Service was studied by conducting a prospective study. Samples were taken from the surface of these materials by sweep plate method prior to washing procedure. The second set of samples were collected from the same materials after the washing procedure. The organisms were identified by colony morphology, culture characteristics & biochemical reactions according to standard techniques. Results: Out of the 30 samples studied, 24 (80%) of them were contaminated with bacteria before washing. Organisms yielded were Staphylococcus aureus, coagulase negative Staphylococcus (CONS), Aerobic spore bearing bacilli (ASB), Escherichia coli and Pseudomonas aeruginosa. After washing, 25 (83%) of the clothes were sterile. Conclusion: Though terminal cleaning fails to completely eliminate bacteria from the laundered fabrics, it is effective in considerable reduction in bacterial growth.

“…The bacteria identified include Staphylococcus aureus, Staphylococcus epidermidis, Proteus mirabilis, Enterobacter aerogenes, Bacillus cereus, Escherichia coli, and Klebsiella aerogenes. This coincides with other reports [13,14,15]. A number of studies specifically focused on searching Hospital Acquired Infections-relevant pathogens, mostly Staphylococcus aureus or Enterococci [16,17] but research reports on microbial load of household bed linens are scanty hence, relatedness of microbial species isolated from household to those from the hospital has not been reported.…”

Bed linen is clearly recognized as a potential reservoir for microorganisms and could be a vector of disease transmission. The present study was aimed at isolating and characterizing bacteria and fungi from different kinds of bed linen of student in Ekiti State University hostels. Pour plate method was used for the enumeration of total bacteria count from the posterior and anterior end of the bed linen. The average bacteria count for the anterior and posterior end was 7.46 and 7.16 Log10 CFU/ml respectively. The most dominant microbial species were bacteria and these were mostly found in the environment and on human skin. The bacteria isolated were Staphylococcus aureus, Staphylococcus epidermidis, Proteus mirabilis, Enterobacter aerogenes, Bacillus cereus, Escherichia coli and Klebsiella aerogenes. Bacillus cereus had the highest frequency of occurrence (25%), followed by Staphylococcus aureus (15%), Escherichia coli (15%), Klebsiella aerogenes (15%), Staphylococcus epidermis (15%), Enterobacter aerogenes (10%) and Proteus mirabilis (5%). The fungi isolates were Aspergillus sulphureus, Aspergillus fumigatus, Aspergillus niger, Aspergillus flavus and Fusarium spp. Antibiotics susceptibility test was carried out on the bacteria isolates with gram negative bacteria showing resistance to Cotrimoxazole and gram positive bacteria showing resistance to Amplicillin. Most of the bacteria isolates have multiple antibiotics resistance. The bacterial isolates were susceptible to Ciprofloxacin. Plasmid profiling was also done with Escherichia coli having three high molecular weight plasmids, Bacillus cereus and Enterobacter aerogenes do not possess plasmid. The identified species are suspected to be opportunistic pathogens for human, representing a risk for people with weakened immune system, especially in cases of super-infection.

“…Overall, none of the washing processes helped decrease bacterial growth at the tube junctions. Moreover, no remarkable differences may have been observed among the washing groups, owing to the redeposition of bacteria [13]. However, a difference was observed in the appearance of the feeding tube junctions.…”

Introduction: International standards for enteral feeding have been introduced, involving the use of feeding tubes with junctions. If these junctions are not properly cleaned, they can become contaminated, leading to microbial infections. We aimed to compare the ease and effectiveness of cleaning by four methods using the number of bacteria. Methods: We compared enteral nutrition tube junctions cleaned using four methods: water, toothbrush, cotton swab, and EnClean® brush; and an uncleaned control. Once daily for 7 days, the tubes were injected with nutrients, cleaned, and incubated at 37 °C. Samples for bacterial culture were collected before injections on days 7, 14, 21, and 28. The culture samples were incubated at 37 °C for 48 h, and the number of colonies was counted. Results: The number of bacteria remaining on day 28 did not differ between 4 cleaning methods and control groups. Also, there was no statistically significant difference in bacterial counts between the four wash methods. The number of washes did not differ among cleaning methods. Conclusion: The bacterial count in the ISO-standardized tube junction increased, and none of the cleaning methods decreased it.
