Prevalence of Cryptococcus neoformans in domestic birds referred to veterinary clinics in Tehran

Prevalence of Cryptococcus neoformans in domestic birds referred to veterinary clinics in Tehran. Cryptococcus is a sub acute or chronic disease. Cryptococcus neoformans is a factor of this infection. This yeast is found in bird feces and can be spread by dust in the respiratory system. Individuals who are immunocompromised are at risk of fungal infection. In this study, 262 fecal samples from birds such as lovebirds, mynah, parrot, Kasku, finches, bridal Dutch and canaries were gathered. The samples were prepared from suspension cultures in S, Sc and BHI and at 25 and 37 ° C were incubated. After 48 hours of staining in cotton blue and Chinese ink we put them under consideration. Then, using sugar fermentation tests, urea hydrolysis and germ tube were identified. The results included a variety of filamentous fungi such as Aspergilus, Alternaria, Escopolariosis, Mucor, Rhizopus and yeasts like Rodoturela, Candidia albicans, Candidia Sp and Pichia. Cryptococcus Neoformans was not isolated. This disability in isolation was due to the birds' hygiene care, keeping them inside the cage and preventing of direct contact with wild birds.
