Abstract
Infectious keratoconjunctivitis is an infectious disease that negatively affects animal welfare causing systemic or local clinical signs in small ruminants and causes significant economic losses in herds. It is important to determine the etiologic agent causing the infection in the development of the protection and control strategies against the disease. The aim of this study was to determine the presence of infectious keratoconjunctivitis cases in small ruminants raised in Siirt province in Türkiye. Infectious keratoconjunctivitis was graded according to the symptoms determined by clinical examination. The presence of Chlamydia spp., Mycoplasma spp. and Moraxella ovis was investigated by PCR in swab samples obtained from the animals with keratoconjunctivitis. Infectious keratoconjunctivitis was detected in 263 (19.86%) of 1324 animals examined in the study. Of the animals with infectious keratoconjunctivitis, 163 (61.97%) were sheep and 100 (38.02%) were goats. The detection rate of infectious keratoconjunctivitis was higher in sheep than goats. In 56 (21.29%), 109 (41.44%), 67 (25.47%), and 31 (11.78%) of the cases, findings of stage 1, 2, 3, and 4 infectious keratoconjunctivitis were detected, respectively. Of the eye swab samples taken from 263 animals with infectious keratoconjunctivitis, 5 (1.90%) were positive for Mycoplasma spp. and 6 (2.28%) were positive for M. ovis. It was determined that the distribution of the bacterial agents varied according to the stage of infectious keratoconjunctivitis. No statistically significant correlation was found in the distribution of bacterial agents among identified samples according to species, sex, age, and infectious keratoconjunctivitis stage of the animals. It was thought that the data obtained in the study would contribute to the studies for protection and control by determining the incidence and aetiology of infectious keratoconjunctivitis cases observed in small ruminants.
