Macrolid resistance in Staphylococcus aureus strains from chicken synovitis and dermatitis in industrial production

In outbreaks of synovitis and dermatitis in chicken caused by Staphylococcus (Staph.) aureus we observed erythromycin-resistant strains. These strains belong to the host-specific variety gallinae of Staph. aureus or can not be alloted to one of the known host-specific varieties. The macrolide-resistance-determinant is not carried by a plasmid, presumably it is located on the chromosome. The strains show constitutively cross-resistance to erythromycin, thurimycin, linomycinc and pristinamycin (M-L-S-phenotype). An ecological investigation in a chicken farm has shown that there is no distribution of Staph. aureus-strains from chicken to workers and no occurence of macrolide-resistance in Staph. aureus-strains from the workers.     

The disposition and clearance of inhaled bacteria (Staphylococcus aureus) in the lungs of piglets

Retention in the lungs of 24 piglets of bacteria inhaled following exposure to an aerosol (dv(50)4 micron) of Staphylococcus aureus (SG511 strain), with clearance periods of differentiated lengths, is reported in this paper. Aerosol inhalation led to heterogeneous deposition patterns in the lung. The highest germ count per gram of lung tissue could be re-isolated from the base lobe, while the lowest germ count was retained in the apical lobe. Germ retention in the other lung lobes was somewhere in between these findings. Such differentiation was detectable as early as 20 minutes from the onset of aerosol application and continued to be largely stable even after clearance periods of 2 and 6 hours.     

Prevalence of Staphylococcus aureus and Methicillin-Resistant Staphylococcus aureus Carriage in Three Populations

Background: A higher prevalence of methicillin-resistant Staphylococcus aureus (MRSA) colonization is reported in healthcare workers compared with nonhealthcare workers.
Hypothesis: The prevalence of MRSA colonization differed in people and pets in households with healthcare workers as compared with households without healthcare workers.
Subjects: A person and 1 dog or cat from 586 households defined as either a nonhealthcare (n = 213), veterinary healthcare (n = 211), or human healthcare (n = 162) worker household.
Methods: Prospective cross-sectional study. Samples from humans and pets were cultured in vitro. Staphylococcus aureus was identified as methicillin sensitive (MSSA) or MRSA with mec A polymerase chain reaction. Pulsed-field gel electrophoresis and spa -typing were used to characterize relatedness of S. aureus and MRSA and assign USA types.
Results: The prevalence of MSSA and MRSA in humans was 21.5% (126/586) and 5.63% (33/586), respectively, and 7.85% (46/586) and 3.41% (20/586), respectively, in pets. There were no differences in prevalences of either MSSA or MRSA between household types. The proportion of MRSA among all S. aureus isolates in humans and pets was 20.8% (33/159) and 30.3% (20/66), respectively. In <1.0% (4/586) of households, the same strain of MRSA was found in both a person and a pet.
Conclusions and Clinical Importance: There were no differences in the prevalences of MSSA or MRSA between healthcare worker and nonhealthcare worker households. Pets and people colonized with S. aureus were as likely to be colonized with MRSA. Colonization of a person and their pet with the same strain of MRSA was rare.
