“…In Ghana, however, a similar study by Tagoe et al (2011) isolated a high percentage of S. aureus and E. coli as well as Bacillus spp. on fomites at the Volta Regional Hospital which indicated a high potential risk of nosocomial infections in that hospital.…”

The study assessed potential sources of nosocomial infections as well as the knowledge of healthcare workers about these infections in a peri-urban polyclinic of Ghana. Swabs were taken in duplicates from beds in the wards, door knobs, sinks, nurses' desks, taps handles, delivery beds, wound dressing rooms, and door and flashing handles of lavatories. After overnight incubation, the samples were serially diluted two times and the third diluent was used in culturing unto plate counting agar, MacConkey agar, blood agar and incubated at 35±2°C for 24 h. The plates were read for colonies and isolated colonies were identified. A simple random method was used to sample the respondents from the various departments in the Polyclinic. Structured questionnaires were administered to solicit their knowledge or understanding of possible causes of nosocomial infections and their perception of the efficacy of the cleaning processes employed in the facility as well as measures put in place to protect healthcare workers from these infections. Data collected showed that Bacillus spp. was the predominant bacterium isolated contributing 64.3% of the total isolate. Out of the 24 pathogenic organisms forming 35.7% of the total organisms isolated, Staphylococcus aureus (94.8%) formed the majority and Pseudomonas aeruginosa (5.2%) was the least isolated. There was no significant difference between the number of isolates recorded before cleaning and after cleaning (P > 0.05) with almost the same number and type of organisms isolated in both cases. Apart from the orderlies who demonstrated little knowledge on nosocomial infections, all the other healthcare workers exhibited adequate knowledge of nosocomial infections. The seemingly high percentage of pathogenic isolates from our study site indicates a high potential risk of nosocomial infections in peri-urban polyclinics.

“…In the current study 30 isolates out of 231 showed >90 % inhibition against S. epidermidis and were further screened for broad range antibacterial activity. Other indicator organisms used in the current study belong to gram positive (M. luteus) and gram negative (E. coli and P. fluorescence) clan and have been reported to cause nosocomial infection [16,[19][20][21]. These infections persist and are resilient to antibiotic treatment.…”

Objective: The aim of the current study was to isolate and identify the bacteriocinogenic strain exhibiting broad range antimicrobial activity and antibiofilm activity from the soil of animal farms.Methods: In the current study, bacterial strains were isolated from soil of twelve different regions of the animal farm all over India and screened for antimicrobial activity against Staphylococcus epidermidis, Micrococcus luteus, Pseudomonas fluorescence and Escherichia coli. Antibiofilm ability of these selected strains was checked on preformed biofilm of S. epidermidis and in addition biofilm disruption potential was also determined. The potent bacterial strain was identified at the molecular level by 16S ribosomal DNA (rDNA) sequencing.Results: 30 out of 231 strains isolated from soil were selected on the basis of antibacterial activity against S. epidermidis. One potential candidate (GAS 101) exhibited ≥99% inhibition against S. epidermidis, M. luteus, P. fluorescence and E. coli and also showed antibiofilm activity. GAS 101 16S rDNA sequencing data identified it as Bacillus subtilis. The sequence of B. subtilis was submitted to genbank under accession no. KJ564301. Conclusion:B. subtilis GAS 101 isolated from soil of animal farm showed the antibacterial activity against all indicator organisms and also displayed antibiofilm activity against preformed biofilm and inhibited biofilm formation of S. epidermidis.

“…The broad spectrum of bacteria isolated here is indicative of the potential of the mobile phones to act as a fomite in similar fashion to paper currency, stethoscopes, ball point pen etc. [11][12][13][14]. This aspect of mobile phones is still unexplored and needs research.…”
