AbstractA patient contact model was devised for health care workers (HCWs) to define heavy hand contamination with aerobic gram-negative bacilli (AGNB) that requires alcohol for complete removal. In patients, AGNB quantitation was per ml cup scrub fluid; in HCWs, per ml glove juice. Following 15-second contact, two Proteeae groin carriers yielding ≥ 4 log10AGNB (high burden) transmitted ≥ 3 log10in 67% of 24 tests of six HCWs, and ≤ 2 log10in 29%. Two carriers yielding ≤ 3 log10(low burden) transmitted ≥ 3 log10in 8% and ≤ 2 log10in 38%. At ≤ 2 log10HCW acquisitions, soap eliminated all AGNB in six of seven tests; alcohol in nine of nine (p > 0.05). At ≥ 3 log10acquisitions, soap eliminated all AGNB in three of 10; alcohol in eight of eight Contacteight (p= 0.009). Contact with densely colonized patient skin may cause heavy AGNB contamination of HCWs' hands that generally necessitates alcohol for complete removal.

Abstract Background The present study attempts to identify and determine the pattern of drug susceptibility of the microorganisms present in mobile phones of health care workers (HCWs) and non-HCWs in a hospital environment. Mobile phones of 100 participants including both genders were randomly swabbed from nine different wards/units and the bacterial cultures were characterized using VITEK 2 system. Results Forty-seven mobile phones were culture positive and a total of 57 isolates were obtained which consisted of 28 Gram-positive organisms and 29 Gram-negative organisms. The predominating organisms were Acinetobacter baumannii and Staphylococcus hominis. Among all the isolates from the mobile phones of HCW and non-HCWs, five isolates had ESBL and three isolates had colistin resistance. Incidentally, MRSA was not found on the mobile phones tested. The isolated organisms showed 100% susceptibility to linezolid, daptomycin, vancomycin, imipenem, meropenem, gentamicin, amikacin, ciprofloxacin and tigecycline, while high resistance was shown against benzylpenicillin (75.0%), cefuroxime and cefuroxime axetil (56.5%). Non-HCWs’ mobile phones were more contaminated as compared to HCWs (P = 0.001) and irrespective of individuals’ gender or toilet habits, both Gram-positive and Gram-negative organisms were present on the mobile phones. Conclusion This study reports for the first time that the mobile phones of non-health care workers harbour more bacterial diversity and are more prone to cause transmission of pathogens. This study can serve to educate the public on personal hand hygiene practices and on maintaining clean mobile phones through antiseptic measures.

SUMMARYA quantitative culture technique (hand washed in a glove containing broth for 30 s) was used to determine the frequency of hand carriage of aerobic Gram-negative rods by various groups of health care workers and 104 control subjects. Overall, 31 % of health care workers carried aerobic Gram-negative rods on their hands compared to 59% of control subjects (P< 0.001).Enterobacter agglomeransaccounted for 40% of the isolates, and otherEnterobacterspp. 7%. Other organisms includedAcinetobacter calcoaceticus21%, Serratiaspp. 11%,Klebsiellaspp. 10%,Moraxellaspp. 3%,Pseudomonasspp. 3%,Proteusspp. 1.5%,Escherichia coli1%;Morganella morganii, Citrobacter freundii, Aeromonassp. and an isolate that was not speciated accounted for 0.5% each. We conclude that endemic hand carriage of aerobic Gram-negative rods by health care personnel is common, but significantly less than that of control subjects.Enterobacter agglomeransis found so frequently on the hands of control subjects that it must be considered part of the normal hand flora.

SUMMARYIn order to determine whether hand carriage of aerobic Gram-negative rods is continuous we used the glove-handwash technique to sample the hands of two groups (four each) of health care workers with normal hands (surgical intensive care unit, medical ward) and one group (four) with hand dermatitis (HD) and a group (five) of control subjects – secretaries with no exposure to patients. Each subject was sampled repeatedly over three to six weeks. The mean number of samples for each group was 25.2, 23.2, 19.8 and 25.8 respectively. The HD group had more samples positive for aerobic Gram-negative rods than did the other two groups of health care workers while the control group had more samples positive than any of the three health care groups.Using various typing schemes and the following definition of continuous carriage (the isolation of an organism of the same serotype, pyocin type or biotype from more than two handwash samples) we found that 4 of 11 subjects from whomKlebsiella pseumoniaewas isolated carried this organism continuously; 2 of 3 carriedPseudomonas aeruginosacontinuously and 4 of 5 of the control subjects carried the same biotype ofEnterobacter agglomeranscontinuously.We conclude that continuous hand carriage of aerobic Gram-negative rods is common and, among health care workers, those with hand dermatitis carry Gram-negative rods more frequently and in greater numbers than health care workers without hand dermatitis.
