Abstract
Domestic and wild birds may act as carriers of human pathogenic fungi, although the role of laying hens in spreading yeasts has never been investigated. We evaluated the presence of yeasts in the cloaca (Group I, n = 364), feces (Group II, n = 96), and eggs (Group III, n = 270) of laying hens. The occurrence and the population size of yeasts on the eggshell, as well as in the yolks and albumens, were assessed at the oviposition time and during storage of eggs at 22 ± 1°C and 4 ± 1°C. A statistically higher prevalence and population size of yeasts were recorded in Group I (49.7% and 1.3 × 104 cfu/ml) and II (63.8% and 2.8 × 105 cfu/ml) than in Group III (20.7% and 19.9 cfu/ml). Candida catenulata and Candida albicans were the most frequent species isolated. Candida famata and Trichosporon asteroides were isolated only from the eggshells, whereas Candida catenulata was also isolated from yolks and albumens. During storage, the yeast population size on the shell decreased (from 37.5 to 8.5 cfu/ml) in eggs at 22 ± 1°C and increased (from 4.6 to 35.3 cfu/ml) at 4 ± 1°C. The laying hens harbor potentially pathogenic yeasts in their gastrointestinal tract and are prone to disseminating them in the environment through the feces and egg...Continue Reading
