ISOLATION AND CHARACTERIZATION OF MYCOPLASMA AND ACHOLEPLASMA FROM PNEUMONIC LUNGS OF GOATS SLAUGHTERED AT FAISALABAD ABATTOIR 0
Among the goats slaughtered at Faisalabad abattoir, pneumonic lungs were collected from 50 animals suspected for contagious caprine pleuropneumonia (CCPP). These samples were subjected to bacteriological studies and 8 isolates were recovered. On the basis of morphological, biochemical a 1d serological characteristics, these were identified as Mycoplasma mycoides subspecies capri (4), acholeplasmas (2) and unidentified mycoplasmas (2).
Isolation of Mycoplasma mycoides from outbreaks of caprine mycoplasmosis in Brazil.
Abstract Two outbreaks of mycoplasmosis in goats apparently caused by organisms found to be related both to Mycoplasma mycoides subsp. capri (PG3) and to the LC biovar of Mycoplasma mycoides subsp. mycoides (Y-goat), are described for the first time in Brazil. The disease affected mainly young goats and was characterized by pneumonia and other respiratory symptoms, kerato-conjunctivitis and septic arthritis. Morbidity and mortality in kids up to four months old were 90 and 65%, respectively.
Colonisation of the respiratory tract of lambs by strains of Mycoplasma ovipneumoniae.
The age and time of year when colonisation of the nasal cavity of lambs by Mycoplasma ovipneumoniae occurs; the persistence of the organism, and its prevalence in the lungs at slaughter were examined in 2 flocks of sheep in New Zealand. No colonisation had occurred at the time of weaning at 6-7 weeks, but M. ovipneumoniae was recovered from most lambs on at least one occasion before they were slaughtered when about 8 months old. In most cases, colonisation of the nasal cavity by M. ovipneumoniae was a transient phenomenon. At slaughter M. ovipneumoniae was recovered from the lungs of 89% of the lambs of one flock and 80% of the other flock. Bacterial restriction endonuclease DNA analysis (BRENDA) of 34 nasal isolates from one flock showed that it was possible to identify 7 "groups" each with markedly different BRENDA patterns. Lambs initially colonised by one strain, often lost that strain, and if recolonisation occurred it was with a different strain. M. ovipneumoniae was recovered at slaughter from the lungs of most lambs, both normal and pneumonic. The isolates from one flock were examined by BRENDA, and approximately 90% of them gave similar or identical patterns. The predominant strain isolated from the lungs had been recovered from the nasal cavity of many of the lambs about 3 weeks earlier. This suggests that the nasal and lung isolates do not represent independent populations. However, nasal strains may differ in their ability to colonise the lungs.(ABSTRACT TRUNCATED AT 250 WORDS)
