Abstract: The lungworm infection is considered one of the main causes of respiratory tract infections among goats in various regions of the globe. Herein, we provided the first evidence of occurrence of Dictyocaulus filaria among goats in Qena governorate, southern Egypt. Migratory larvae in fecal samples of tested goats (n=67) were detected using modified Baermann method; the standard method for diagnosis of lungworm infection. Among goats exhibiting chronic respiratory distress, high incidence of D. filaria was recorded (22/67: 32.84%). Higher infection rate was observed during the seasons of winter and autumn (50% and 44%, respectively) than the summer and spring (0%, 18.8%, respectively), assuming to the favorable environmental conditions for survival of the infective 3rd stage larvae. Concerning the age, the infection rate was apparently lower in group of mid-aged (25-48 month; 25%) than young (6-24 month; 37.5%), and old aged (49-84 month; 34.8%) animals. The infected goats
