Pig Husbandry

In countries with intensive pig husbandry in stables, the prevalence of livestock-associated (LA) methicillin-resistant Staphylococcus aureus (MRSA) on such farms has remained high in the last few years or has also further increased. Simple measures to reduce the LA-MRSA among pigs have not yet been successfully implemented. Earlier publications showed a decontamination of LA-MRSA was only possible with great effort. The aim of this study is to determine the suitability of routine cleaning and disinfection (C&D) for adequate LA-MRSA decontamination. For this purpose, at least 115 locations in a piglet-rearing compartment were examined before and after cleaning and disinfection. The sample locations were stratified according to accessibility for pigs and the difficulty of cleaning. The cleaning work was carried out routinely by farm employees, who were not informed about the sampling (single blinded). While before cleaning and disinfection, 85% of the samples from the surfaces were LA-MRSA positive, while only 2% were positive thereafter. All LA-MRSA-positive samples after cleaning and disinfection were outside the animal area. Air samples also showed no LA-MRSA after cleaning and disinfection. Conclusion: In well-managed livestock farms, decontamination of the LA-MRSA barn is quite possible; after C&D no LA-MRSA was detectable at animal height.

ABSTRACT Methicillin-resistant strains susceptible to gentamicin (Gm s MRSA) have emerged since 1993 in several French hospitals. To study whether particular clones have spread in various French cities and whether some clones are related to gentamicin-resistant (Gm r ) MRSA strains, various methods (antibiotyping, phage typing, determination of Sma I macrorestriction patterns before and after hybridization with IS 256 transposase and aacA-aphD probes) were used to compare 62 Gm s MRSA strains isolated from 1995 to 1997 in nine cities and 15 Gm r MRSA strains. Eighteen major Sma I genotypes were identified, of which 11 included only Gm s MRSA strains and 5 included only Gm r MRSA strains. Each of the Gm r MRSA strains contained 6 to 13 Sma I fragments hybridizing with the insertion sequence IS 256 , of which a single band also hybridized with the aacA-aphD gene. No such hybridizing sequences were detected in 60 of the 62 Gm s MRSA strains. Thus, the divergence between Gm r and Gm s MRSA strains is revealed, not only by their distributions in distinct Sma I genotypes but also by the differences in hybridization patterns. Two of the 62 Gm s MRSA strains had the uncommon feature of carrying several Sma I bands hybridizing with IS 256 , suggesting that they are possibly related to the Gm r MRSA strains grouped in the same Sma I genotype. Five of the 11 Sma I genotypes including only Gm s MRSA strains contained strains from diverse cities, isolated during different years and with different antibiograms, suggesting that some clones have spread beyond their cities of origin and persisted.

AbstractTo determine the frequency of isolation of methicillin-resistant Staphylococcus aureus (MRSA) at Veterans Administration Medical Centers, 163 hospitals were surveyed; 137 responded. Between 1975 and 1984, the number of Veterans Administration Medical Centers with known MRSA increased from 3 to 111. This increase was geographically widespread and occurred in hospitals of all sizes. In Veterans Administration Medical Centers, isolation policies for MRSA-infected patients were (% of hospitals using): strict (19%), contact (52%), site-related (28%), no isolation (1%). For patients colonized with MRSA policies were: strict (15%), contact (44%), site-related (35%), and no isolation (6%). Only 41% of Veterans Administration Medical Centers reported discharging known MRSA-colonized patients to nursing homes. Most attempts to eradicate MRSA carriage used trimethoprim-sulfamethoxazole plus rifampin with or without bacitracin ointment; success rates were low. MRSA incidence is increasing at Veterans Administration Medical Centers across the United States. Improved regimens to eliminate MRSA carriage are needed.

AbstractAt the Ann Arbor Veterans Administration Medical Center, 30 patients over a 6-month period became nosocomially infected or colonized by methicillin-resistant Staphylococcus aureus. Immediate institution of strict infection control measures, in conjunction with surveillance cultures of personnel and treatment of carriers, did not limit spread of the outbreak strain of MRSA. Multiple nonoutbreak strains, phenotypically exhibiting heteroresistance, were also uncovered. Thirteen hospital personnel were identified as MRSA carriers. Trimethoprim-sulfamethoxazole (TMP-SMX) and rifampin initially eradicated the carrier state, documented by anterior nares cultures in 13 courses of treatment in 11 employees. However, three employees were recolonized, one at one month, one at both one and four months, and one at four months. Treatment of the carrier state reservoir among personnel appeared to have no effect on the emergence and spread of nosocomial MRSA.
