were infected with T. gallinae protozoon parasite. In the present study it was found that the two examined bird species were infected with this protozoon and there was a gradual rise in prevalence of infection from beginning to end of the study. Small variations in the prevalence rate of T. gallinae infection between doves (20.42%) and domestic pigeons (23.36%) were observed but this variation not reached to the level of statistical significance (P >0.05). It is worthy to note that in all of the infected birds in the study Trichomoniasis occurred without observation of any apparent secondary diseases or signs. In conclusion Trichomoniasis is less common in urban doves and domestic pigeons in Garmian area, Kurdistan Region-Iraq. Further research is suggested in relation to protozoan parasite in other bird species in a study will be conducted in all months of the year to find the reasons which affect the prevalence rate of infection and to estimate the parasite-host relationship.

The outbreaks of aspergillosis in broiler chicks (4-15 days old) were observed from January to July, 2011 in five broiler farms. The disease was detected on the basis of clinical signs, gross, histopathological and cultural findings. Infected chicks showed signs of ruffled feathers, green watery diarrhea, anorexia, gasping and dyspnea. On examination, numerous small white yellowish nodules were seen in the lungs, air sacs, kidneys, thoracic wall and abdominal serosa. Microscopically the lungs revealed granulomas with central areas of caseation surrounded by heterophils and giant cells. Aspergillus fumigatus could be isolated in Sabouraud’s dextrose agar from the lesions. Higher morbidity (76 to 100%) and mortality (62.5 to 100%) rates were recorded in the five farms. This is the first record on the occurrence of acute aspergillosis in broiler chicks from Sulaimania/ Iraq.
