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).
Subdivision of Mycoplasma mycoides subsp. mycoides from cattle and goats into two types.
Some strains of Mycoplasma mycoides subsp. mycoides, mostly isolated from goats, grow to greater turbidity in broth and form larger colonies on solid medium than does the type strain, PG1. These strains also digest casein, liquefy inspissated serum actively and survive longer at 45 degrees C and are referred to as LC (large colony) strains. Strains more closely resembling PG1 have been called SC (small colony) strains. The SC strains comprise those from contagious bovine pleuropneumonia (CBPP) and some from goats. One LC strain was isolated from a steer; all others have come from goats. Differentiation of M. mycoides subsp. mycoides into 2 types on the basis of the characteristics described may be relevant to their role in CBPP.
The adrenal glands in cystic fibrosis. Morphology correlated with clinical findings.
The findings obtained by morphological investigation of the adrenal glands from 23 patients with cystic fibrosis (CF), have been compared with the findings in 46 controls. In 14 patients with CF, changes in the form of necrosis and/or haemorrhage in the permanent cortex were found and, in addition, in 3 of these there was an accumulation of lipid. The changes were independent of age. In 8 control patients, similar changes localized to the same site were found, but almost exclusively in older children. No correlation was found between these changes and the clinical course of the disease. A number of different investigations suggesting changes in the steroid metabolism in CF are reported.
