Abstract :

Today, modern hatchery plays an important role in the development of the poultry industry.However, the arrival of large numbers of eggs to hatchery increase the likelihood of infectionwith various microorganisms, especially fungal and bacterial contamination. Characterization ofmicrobial contamination and the prevention of this type pollutions can lead to decreasing theincidence of disease in day-old chicks and prevent economic losses. The aim of the currentstudy was to determine fungal contamination in different parts of Mazandaran provincehatcheries. The samples were taken from different parts of hatcheries through a passivesedimentation method onto Sabouraud dextrose agar containing chloramphenicol and incubatedat 30˚C for 7–10 days. Furthermore, the type and number of fungal colonies were recorded.Fungal isolates belonged to seven genera: Aspergillus (87.8%), Mucor (4.3%), Penicillium(3.5%), Rhizopus (1.6%), Fusarium (1.4%), Alternaria (0.7%) and Cladosporium (0.7%).Aspergillus was the most common genera of isolated fungi and Aspergillus flavus with the15361 (71.4%) number of colonies was the most common fungal species isolated from theincubation systems. In general, Setter and Hatcher rooms were the most polluted parts of theincubators. According to high pollution of hatchery centers with various fungi, especiallyAspergillus species Trying to diagnose, Prevent and eliminate of these contaminations seemnecessary.
