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).
Pulmonary mycoplasmoses of small ruminants.
The various microscopical, microbiological and serological methods currently available for the diagnosis of mycoplasmoses, in particular those involving the respiratory tract of small ruminants, are outlined and compared in Chapter III. Particular emphasis is given to the practical aspects of mycoplasma isolation, cultivation and identification, and details of suitable media are provided in an Appendix.
The etiology and surgical management of tracheal collapse in calves.
The mean ages of 10 calves with tracheal collapse were 2.7 weeks at onset of clinical signs and 9.4 weeks at presentation for treatment. Inspiratory and expiratory dyspnea and stunted growth were the most common clinical signs. There were abnormalities of the cranial ribs consistent with healing fractures with redundant callus in eight lateral thoracic radiographs. Tracheal collapse in calves may result from cranial thoracic trauma during or soon after birth. Short polypropylene ring prostheses made from 60 ml syringe barrels were placed on the tracheas of four calves with cervical tracheal collapse. There were cranial rib masses in all calves and resection of the right first and second ribs was necessary in one calf to allow placement of prostheses. Dyspnea was relieved in all calves. One calf died of unrelated causes in year 3, and one calf had recurrence of clinical signs at month 5 and was euthanatized. In both calves, tracheal stenosis resulted from continued growth and infolding of the trachea within the constraints of the prostheses. One calf was alive at month 11, and one calf died of acute bronchopneumonia on day 2. Removal of tracheal prostheses in calves is recommended after 2 to 3 months if clinical signs recur.
