Antibiotic susceptibility of Staphylococcus aureus strains responsible for community-acquired skin infections

BACKGROUND: The appearance and worldwide spread of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) skin infections warrant new studies of antibiotic resistance among strains of S. aureus responsible for cutaneous infections seen in general practice. PATIENTS AND METHODS: A prospective, multicentre study was performed from December 2003 to August 2004 in outpatients of both sexes presenting with a common bacterial skin infection presumed due to S. aureus (primary or secondary impetigo, ecthyma, paronychia, folliculitis, furunculosis). The investigators (n=50) were GPs from seven French regions. Clinical data (history, previous hospitalisation, type of infection, site, previous treatment, etc.) were collected using a standard questionnaire. A bacteriological sample was taken in attempt to isolate S. aureus after which antibiograms were prepared and minimal inhibiting concentrations determined (11 antibiotics). RESULTS: Four hundred and eighty patients of mean age 42 years (range: 2-94 years) were included. S. aureus was isolated from cultures in 205 of 477 samples, i.e. in 197 patients (eight had two strains of S. aureus). Patients with S. aureus had a primary skin infection in 104/197 cases (53%) (24 impetigo, 20 paronychia, 45 folliculitis or furunculosis) and a secondary infection in 93/197 cases (47%), with 4.9% patients being hospitalized within the preceding six months (median: 10 days). Percentages of resistant S. aureus strains were as follows: penicillin: 86%, erythromycin: 32%, ciprofloxacin: 9.3%, tetracycline: 5.8%, oxacillin: 5.8% (representing MRSA strains), fusidic acid: 4.4%, clindamycin: 3.4%, mupirocin: 1% and gentamicin: 0.5%. All S. aureus strains were sensitive to vancomycin and rifampicin. Except for one strain also resistant to tetracycline and fusidic acid, all MRSA strains were also resistant to ciprofloxacin. DISCUSSION: Multiresistant bacterial strains could become a concern in the community in France in the near future. In our study, only 14/197 (6.8%) S. aureus strains were sensitive to all tested antibiotics, whereas 21/197 (10.7%) were resistant to at least three of them. Compared to a French study performed in private practice in 2000, the level of MRSA is growing only slowly (5.8% versus 3.9%), whereas the percentage of strains of Peni-R/Oxa-S S. aureus are stable (80.5%). CONCLUSION: Common bacterial infections of the skin due to MRSA or to multiresistant S. aureus are not rare in France and have tended to increase slowly in recent years.

Bacterial culture and sensitivity in pemphigus

Infection is the commonest cause of death in pemphigus and the commonest infection is Staphylococcus aureus bacteremia. In present study bacterial culture and sensitivity from the lesion was done in 25 patients of pemphigus vulgaris and accordingly antibiotics were given along with other treatment of pemphigus i.e. steroid, immunosuppressive drug etc. Most common pathogenic bacteria isolated was Staphylococcus aureus and it was sensitive to cloxacillin, erythromycin, cefotaxime and lincomycin.     

Methicillin resistant staphylococcus aureus (MRSA) in skin isolates from hospital acquired infections

Eighty-four isolates of Staphylococcus aureus (S.aureus) obtained from nosocomial infections were screened for methicillin resistance, which was found to be about 40.47%. This indicates a rising trend in the incidence of MRSA over the previous years. Early detection of resistant strains as well as prudent use of antibiotics can help to combat the global problem of resistance.     

Microbiologic evaluation of skin wounds: alarming trend toward antibiotic resistance in an inpatient dermatology service during a 10-year period

BACKGROUND: Increasing resistance to commonly used antibiotics has been seen for patients with superficial skin wounds and leg ulcers. OBJECTIVES: We sought to evaluate bacterial isolates from leg ulcers and superficial wounds for resistance to commonly used antibiotics and to compare current data with previous data. METHODS: We performed a chart review for patients admitted to a tertiary care dermatology inpatient unit from January to December 2001. Comparison was made with 2 previous surveys of the same inpatient service from 1992 and 1996. RESULTS: Bacterial isolates were cultured from 148 patients, 84% (72 of 86) with leg ulcers and 38% (76 of 202) with superficial wounds. Staphylococcus aureus and Pseudomonas aeruginosa were the most common bacterial isolates in both groups. For patients with leg ulcers, S aureus grew in 67% of isolates (48/72) of which 75% (36/48) were methicillin-resistant (MRSA). Of leg ulcers, 35% (25/72) grew P aeruginosa, which was resistant to quinolones in 56% of cultures (14/25). For patients with superficial wounds, S aureus was isolated in 75% (57/76) and 44% were MRSA (25/57). P aeruginosa grew in 17% of isolates (13/76) and was resistant to quinolones in 18%. We found a marked increase in antibiotic resistance for both leg ulcers and superficial wounds. Over time, MRSA increased in leg ulcers from 26% in 1992 to 75% in 2001. For superficial wounds, MRSA increased from 7% in 1992 to 44% in 2001. P aeruginosa resistance to quinolones in leg ulcers increased from 19% in 1992 to 56% in 2001, whereas for superficial wounds there was no resistance in 1992 and 18% resistance in 2001. CONCLUSION: Rapid emergence of antibiotic-resistant bacteria continues and is a problem of increasing significance in dermatology. Common pathogenic bacteria, S aureus and P aeruginosa, showed increased resistance to commonly used antibiotics. Selection of antibiotics should be on the basis of local surveillance programs.     

Susceptibility of Staphylococcus aureus to fusidic acid: Canadian data

BACKGROUND: Ongoing antimicrobial surveillance is important to ensure proper management of infectious diseases. There are inherent issues in estimating the relevant incidence of antimicrobial resistance from surveillance data and special issues for topical preparations. OBJECTIVE: To perform semiannual surveillance of fusidic acid susceptibility of Staphylococcus aureus strains in a Canadian tertiary care hospital. METHODS: S. aureus strains were collected twice yearly from routine cultures. Routine antimicrobial susceptibility testing was performed by an automated method. Fusidic acid susceptibility testing was performed by disk diffusion. RESULTS: Between 1999 and 2005, 2,302 S. aureus strains were tested, of which 240 were methicillin resistant (MRSA). Among all strains tested, 65 (2.8%) were resistant to fusidic acid. Ten of the MRSA strains (4.2%) were resistant to fusidic acid. Although from different patients, these were shown to be part of a hospital outbreak and were epidemiologically linked. CONCLUSIONS: There has been no trend toward increasing fusidic acid resistance in our hospital over this period.

Bullous erysipelas: clinical presentation, staphylococcal involvement and methicillin resistance

BACKGROUND: Erysipelas is a bacterial infection of the dermis and hypodermis, mostly of streptococcal origin. Bullous erysipelas represents a severe form of the disease. OBJECTIVE: To evaluate the clinical and microbiological characteristics and treatment of bullous erysipelas. METHODS: Patients with a diagnosis of bullous erysipelas who were treated at the Department of Dermatology, University Hospital of Heraklion, Crete, Greece, between the years 1996 and 2001 were retrospectively studied. RESULTS: Fourteen patients (11 women, 3 men) with bullous erysipelas were evaluated. The lesions were located on the legs and face in 9 and 4 patients, respectively. The median duration of disease before hospital admission was 4 days. Eight patients had fever at presentation. Local trauma and various lesions were common causes for pathogen entry. The initial empirical antibiotic treatment included intravenous beta-lactams and was modified according to the sensitivities of the isolated strains. Staphylococcus aureus was isolated from 7 (50%), while S. warneri, Streptococcus pyogenes and Escherichia coli grew from the lesions of 3 other patients. Six out of 7 S. aureus strains were methicillin resistant (MRSA) but susceptible to several other non-beta-lactam antibiotics such as quinolones, vancomycin, rifampicin and trimethoprim/sulfamethoxazole. CONCLUSION: Our findings suggest that S. aureus is frequently involved in and probably contributes in synergy with beta-hemolytic streptococci to the complicated course of bullous erysipelas. The frequency of MRSA isolation suggests that beta-lactam antibiotics may not be sufficient for the treatment of bullous erysipelas anymore, at least in areas with a high incidence of MRSA strains. The role of other classes of antibiotics providing adequate coverage for MRSA has to be evaluated in prospective clinical trials.
