[Correlation in the guinea pig between the appearance of vaginal leukocyte changes and mating]. / Correlazione, nella cavia, tra la comparsa del flusso leucocitario vaginale e l'accoppiamento.

The AA. have carried out researches on the cronological relation between leukocytarian flow and male acceptance. They have used colpocitological tests brought on twice a day on 41 female guinea pigs. On the basis of their results the Authors can state that in this species the period of male acceptance is covered within 14 hours every cycle. In about 50% of subjects the period starts with vaginal opening and probably the mating precedes the leukocytarian flow.

[Some components of preputial bacterial flora in the ram]. / Osservazioni su alcuni componenti della flora batterica prepuziale nell'ariete.

During the reproductive period the AA have carried on bacteriological researches in the preputial cavity in eight sardinian rams, without pathological processes, living in eight flocks in the country around Sassari, in order to detect the bacteriological flora. This flora could interfere both with fertility and with conservation of seminal material for artificial insemination. Three withdrawals have been carried on before, during and after the reproduction season. E.coli, P. mirabilis, Staph. epidermidis have been found in the varius examined subjects. The AA stress that the same bacterium which had been isolated in the first withdrawal. Moreover in some subjects the bacteriological flora had increased. The AA stress how these data can be useful in order to control the flock fertility and in order to improve the technology of conservation of seminal material.
