Abstract:
Investigations were conducted on samples of the pathological material,
represented by 17-18 day embryonated eggs, unviable chickens that died in the first two days
after hutching, and incubation wastes (eggshells). For germ isolation, inseminations were
carried out on usual mediums (gelose and nutritive bullion) and on selective and enriching
growth mediums (Chapmann, Drigalsky, Levin, Wilson-Blaire and Istrate-Meitert). The
bacteriological exam allowed the isolation of a mixed flora, represented by Proteus vulgaris,
Escherichia coli, Bacillus cereus, Staphylococcus aureus and Salmonella spp. In most cases,
the germs were associated by two or three. Most of the strains were isolated from the strains of
Escherichia coli - 82 (15.12%), Proteus vulgaris - 66 (12.36%), Staphylococcus aureus - 42
(7.93%), Bacillus cereus - 31 (5.72%) and Salmonella spp. - 5 (0.92%).
