[respiratory diseases of swine: some epidemiologic aspects].epidemiological surveys enable to know better the aetiology of respiratory diseases. the surveys carried out in slaughter-houses in brittany (france) in 1980 and 1981, show a worrying situation concerning porcine respiratory diseases. microbiological studies brought out the preponderance of the isolation of mycoplasma hyopneumoniae, pasteurella multocida, bordetella bronchiseptica, streptococcus suis and actinobacillus suis. some patterns of experimental infection with mycoplasma hyopneumoniae a ...19854064626
bacterial taxa associated with the hematophagous mite dermanyssus gallinae detected by 16s rrna pcr amplification and ttge fingerprinting.dermanyssus gallinae (arthropoda, mesostigmata) is suspected to be involved in the transmission of a wide variety of pathogens, but nothing is known about its associated non-pathogenic bacterial community. to address this question, we examined the composition of bacterial communities in d. gallinae collected from standard poultry farms in brittany, france. genetic fingerprints of bacterial communities were generated by temporal temperature gradient gel electrophoresis (ttge) separation of indivi ...200919027065
