“…As expected, the anterior nares yielded S. aureus more frequently than did the skin. Prevalence in the nose was similar to the values of about 30% or more that have been frequently reported in the literature (16,20). Of the 26 subjects from whom S. aureus was recovered on the skin, 14 (54%) also carried the organism in the nose, again indicating that there is a positive rela- ' Significantly different from controls (P < 0.05).…”

The effects of ad lib use of an antibacterial soap containing 1.0% trichlorocarbanilide and 0.5% trifluoromethyldichlorocarbanilide on the bacterial flora of six skin sites of 132 subjects were measured by comparison with the flora of 93 control subjects who avoided the use of topical antibacterials. Each subject was examined once. The test soap produced significant reductions in geometric mean counts of the total aerobic flora on the back, chest, forearm, calf, and foot; counts were also reduced in the axilla, but not to a significant extent. The overall reduction by the test soap on all sites was 62% ( P < 0.001). Neither age nor sex influenced the effect of the soap on the flora. The antibacterial soap also reduced the prevalence of Staphylococcus aureus on the skin, mostly by virtually eliminating it from areas other than the axilla. Partial inhibition of the gram-positive flora was not accompanied by an increase in gram-negative species. The latter were found principally in the axilla; Klebsiella pneumoniae and Enterobacter aerogenes were the species most frequently found.

“…Recent studies of the hospital ecology of S. aureus did not identify predominant phage types among nosocomially acquired staphylococcal infections (4,18,23,24,26). In contrast, we previously reported that a limited number of S. aureus phage types were isolated from the blood of patients from our hospital over a 1-year period (6).…”

The acquisition of hospital strains of Staphylococcus aureus by new house officers was studied in an 800-bed referral hospital over a 1-year period. S. aureus isolates, including three strains with characteristic phage patterns that had previously been documented to cause disease in patients and colonize hospital personnel, were recovered from the anterior nares of 35 of 54 newly arrived house officers. There was a significant correlation (r = 0.7475; P < 0.02) between colonization with the dominant hospital strain (S) and exposure to the hospital environment over 12 months. No hospital-wide increase in infections owing to the S strain was seen during this period, which suggests that house staff acquired this strain from reservoirs within the hospital. The finding of colonization with virulent endemic S. aureus strains in house officers working on every ward of the hospital suggests that new strategies for control of S. aureus nosocomial infections must be considered and evaluated.

“…The introduction of phage typing to epidemiological surveys of hospitalized patients for up to 20 years demonstrated that once carriers are colonized with certain strains of S. aureus, they generally maintain that strain and become sources of infection (33). Recent studies of the hospital ecology of S. aureus did not identify predominant phage types in nosocomially acquired staphylococcal infections (9,24,(31)(32)(33). In contrast, Cross et al (11) reported that a limited number of S. aureus phage types were isolated from the blood of patients over a 1-year period.…”

Nontypeable bacteriophage patterns of methicillin-resistant Staphylococcus aureus involved in a hospital outbreak

1989

Of 93 strains of Staphylococcus aureus isolated from inpatient wards of Ismailia General Hospital, 48 (51 %) were proven to be methicillin resistant (MR). Of these MR S. aureus strains, 44 were isolated from patients and 4 were isolated from healthy carriers, who were newly arrived interns working in the same wards. Bacteriophage patterns of MR S. aureus were identified by using routine test dilution (RTD) and 100-fold dilutions (100 RTD) of phages. Of these 48 strains, 37 (75%) (33 from patients and 4 from interns) were nontypeable when using RTD and 100 RTD of phages. Of the other 11 strains, 8 were nontypeable by RTD of phages, but 5 of them had the phage pattern D11/1136 when tested by 100 RTD. Three strains had the phage pattern 3A/3C/55/71, and three strains had different phage patterns, 29/81, 96, and 95/D11. The finding of colonization with virulent MR S. aureus strains in interns working on the wards in which these patients were located suggested that new strategies for control of MR S. aureus nosocomial infections must be considered and evaluated.
