SummaryThe present study was undertaken to investigate the frequency of the nasal carrier rate ofStaphylococcus aureus. The investigation was performed on 104 healthy persons. The total number of swabs performed was 1498 and this resulted in isolation of 522S. aureusstrains. All strains have been identified, tested for antibiotic susceptibility, and phage-typed. The carrier-index (number of positive swabs/number of total swabs for each individual person) was compared with different sampling and culturing methods, phage type, age, and resistance to antibiotics. There was statistical difference in carrier rate according to sex (P·05). Among the 104 persons 15 (14·4%) were persistent carriers, 17 (16·3%) intermittent carriers, 55 (52·9%) occasional carriers and 17 (16·3%) non-carriers. Among intermittent and occasional carriers the phage-type distribution was different from theS. aureusstrains isolated from Danish hospitalized patients in 1992, while the persistent carriers had similar phage-type distribution.

The present study on the acquisition of Staphylococcus aureus by patients during their stay in a mental hospital, and the nasal carrier rate in the institutionalized patients, was prompted by the fact that in 1959 and 1960 193 out of a total of 407 deaths in Napsbury Hospital were due to lung infection, and that a bacteriological study of 45 unselected cases at necropsy in 1960 had suggested that the fatal lung infections were predominantly staphylococcal (Table I). The incidence of staphylococcal skin lesions, however, remained low, and only 147 cases of this kind were reported during 1959 and 1960 (4 per cent. per annum of the population) (Table II).

Objective. To determine the prevalence of Staphylococcus aureus strains among hospitalized patients at the beginning of their hospitalization and during their treatment and the resistance of strains to antibiotics, and to evaluate epidemiologic characteristics of these strains. Patients and methods. Sixty-one patients treated at the Department of Cardiac, Thoracic and Vascular Surgery were examined. Identification of Staphylococcus aureus strains was performed using plasmacoagulase and DNase tests. The resistance of Staphylococcus aureus to antibiotics, b-lactamase production, phagotypes, and phagogroups were determined. The isolated Staphylococcus aureus strains were tested for resistance to methicillin by performing disc diffusion method using commercial discs (Oxoid) (methicillin 5 mg per disk and oxacillin 1 mg per disk). Results. A total of 297 Staphylococcus aureus strains were isolated. On the first day of hospitalization, the prevalence rate of Staphylococcus aureus strains among patients was 67.3%, and it statistically significantly increased to 91.8% on days 7–10 of hospitalization (P<0.05). During hospitalization, patients were colonized with Staphylococcus aureus strains resistant to cephalothin (17.6% of patients, P<0.05), cefazolin (14.6%, P<0.05), tetracycline (15.0%, P<0.05), gentamicin (37.7%, P<0.001), doxycycline (30.7%, P<0.001), and tobramycin (10.6%, P>0.05). Three patients (4.9%) were colonized with methicillin-resistant Staphylococcus aureus strains, belonging to phage group II phage type 3A and phage group III phage types 83A and 77; 22.6– 25.5% of Staphylococcus aureus strains were nontypable. During hospitalization, the prevalence rate of phage group II Staphylococcus aureus strains decreased from 39.6% to 5.7% (P<0.05) and the prevalence rate of phage group III Staphylococcus aureus strains increased to 29.5% (P<0.001). Conclusions. Although our understanding of Staphylococcus aureus is increasing, well-designed communitybased studies with adequate risk factor analysis are required to elucidate further the epidemiology of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus. Surveillance of methicillin-resistant Staphylococcus aureus provides relevant information on the extent of the methicillin-resistant Staphylococcus aureus epidemic, identifies priorities for infection control and the need for adjustments in antimicrobial drug policy, and guides intervention programs.

AbstractFrom September 14, 1981 to February 28, 1982, an epidemic of bullous impetigo caused by a penicillin/tetracycline resistant strain of Staphylococcus aureus, phage type 3A/3C, occurred in a newborn nursery in Louisville, Kentucky. Twenty of 1,181 (1.7%) infants at risk developed disease during the six-month epidemic period. Clinically all case-infants had bullous impetigo skin lesions. One infant developed staphylococcal septicemia. No infant died. An epidemiologic investigation identified a nurse as having significantly greater contact with case-infants than control-infants (p=0.0013). She was also found to be a nasal carrier of the epidemic strain. Infection control measures appeared to decrease infant-to-infant transmission via the hands of non-colonized nurses, but did not affect transmission from the nurse carrying the epidemic strain to infants. No cases of bullous impetigo have occurred since this nurse was temporarily removed from the nursery for treatment.

SUMMARYThe spread of Staphylococcus aureus was studied in three general surgical wards of identical design which consisted of a number of separate rooms, and the results were compared with those in the same unit previously studied, in subdivided wards elsewhere and in large open wards.The nasal carrier rate of Staph. aureus by patients rose during their stay in the ward, but its peak rate was comparable with minimum rates reported in other subdivided wards and was lower than in open wards.Staphylococcal sepsis rates were lower than in most open wards and were also much lower than those found previously in the same unit when overcrowding was common and each sex had its own ward.

We studied the incidence of staphylococcal infection in a thoracic surgery ward which consisted of a number of separate rooms, and inquired whether the subdivision of the ward was responsible for the unusually low sepsis-rate.The airborne dissemination of Staphylococcus aureus from one room to another appeared to be little less than that in an open ward; but the total number of Staph. aureus in the air was very low.Most of the patients received prophylactic antibiotics. The nasal carrier-rate of Staph. aureus by patients fell greatly during their stay in the ward. There was a progressive disappearance of sensitive organisms and little acquisition of multiple-resistant organisms.When there are urgent clinical grounds for the lavish use of antibiotics, the dangers appear to be reduced by effective segregation of the patients from each other.

AbstractIn late January and early February 1983, an outbreak of skin infections (7 of 145 infants) caused by a penicillin/erythromycin resistant strain of Staphylococcus aureus (SA), phage type 3A/3C, occurred in our newborn nursery. A week following the first cluster of infections, another nursery outbreak due to SA with the same antibiogram occurred in a nearby community hospital (11 of 114 infants). Subsequently, a second cluster of infections with the same SA was identified at our nursery. The epidemic strain was carried in the anterior nares of a single nurse who worked at both hospital nurseries on alternate weeks. Investigation revealed that the nurse had an upper respiratory tract infection during each of these outbreaks—simulating “a cloud baby.” No further infections have occurred since this nurse was treated and her SA nasal carrier state eliminated.

Nose, throat and finger carriage of Staphylococcus aureus was investigated in a series of random samples from a normal European population.No evidence for a seasonal trend in carriage was found but the intersample variation between successive random samples was obtained. The mean nasal carrier rate was 29 % with a standard deviation of 7 %.No association was found between nasal or throat carriage of staphylococci and stay in hospital or antibiotic therapy but respondents with penicillin-resistant staphylococci in the nose had skin infections more frequently than those with penicillin-sensitive strains.Evidence was obtained for a family, perhaps genetic, ‘predisposition’ to carry staphylococci in the nose.

Staphylococcus aureus (S. aureus) has long been recognized as an important human pathogen causing many severe diseases. It is also a part of human normal flora with its ecological niche in the human anterior nares. This study focused on screening S. aureus nasal carriage in community and its relationship to human physiological and pathological factors which have not been studied in Vietnam previously. Two hundred and five volunteers in Ho Chi Minh City from 18 to 35 and over 59 years old both male and female participated in the study. Result showed that the prevalence of S. aureus nasal carriage in southern Vietnamese community was relatively low, only 11.2% (23/205), much lower than that in other international reports on human S. aureus. In addition, nasal carriage of the older age group (> 59 years old, 13.7%) was higher than that of younger age (18-35 years old, 10.4%). Other potential risk factors such as gender, career, height, weight, history of antibiotic usage, daily nasal wash, use of nasal medication sprays, acne problems, smoking and nasal problems showed no significant impact on S. aureus carriage. The obtained S. aureus nasal isolates were all sensitive to vancomycin. Lincomycin and tetracycline had low resistance rate with 4.3 % and 17.4 %, respectively. However, the isolates showed particularly high rate of multidrug resistance (54.2%) In summary, our data provided researchers an overview on S. aureus nasal carriage and antibiotic susceptibility profile of the community- isolated S. aureus in Vietnam. This would serve as valuable information on assessing risk of community-acquired S. aureus infections.
