Clostridium difficile was incriminated by Hughes and Jarvis (1987) as a cause of intestinal infections in USA in the 1980-1984 period in 45 p. 100 of cases, whereas Salmonellae only in 12 p. 100.

The clinical, serologic and pathohistological study was carried out on laboratory animals inoculated with a series of rabies vaccines currently used in postinfection therapy in man and some experimental rabies vaccine variants used throughout the world, in order to estimate the reactive, allergic-inducing and encephalitogen potential of the products. The results showed that all the virulent material used in the preparation of rabies vaccines studied have an allergoencephalitogenic potential, reflected by humoral and histologic modifications, especially contraindicated being the avian rabies vaccines and those prepared from adult animal nervous material. Vaccines prepared from cell cultures, virulent brain of the neonate mouse and normal lamb present and allergoencephalitogen and neuropathogen potential that must be taken into consideration within the context of a repeated postinfection therapy.

An investigation of 272 non-human primates (75 Macacca cynomolgus, 97 Macacca mulatta and 100 Cercopithecus aethiops) revealed a high incidence of respiratory disease caused by Corynebacterium ulcerans, Staphylococci, Diplococci and Streptococci. Escherichia coli was also found as a secondary invader. Most of the infections occurred during winter in Macaca cynomolgus and were caused by Corynebacterium ulcerans and Diplococcus pneumoniae.

Repeated inoculation of homologous parathyroid tissue in dogs induced isoimmune hypoparathyroidism, with all the characteristic biochemical and histopathological features and the presence of complement fixing antibodies in the serum. Disturbances of calcium and phosphorus metabolism were similar to, but less severe than, those observed in dogs with hypoparathyroidism induced by complete thyro-parathyroidectomy. Injection of rabbits with crude extracts of dog, rat, hog and human parathyroid or with bovine parathormone (PTH), each incorporated in Freund's adjuvant, resulted in the development of complement fixing and precipitating antibodies: these reacted with the corresponding tissue preparations, but did not show cross-reactivity.
