Abstract

A mass occurrence of conjunctivitis was observed among young Barbary ducks. The disease first appeared before the breeding period after the animals have been transferred to their accommodation. The initial acute stages progressed to a more serious chronic fibrinous form. Apart from directly affecting the eye and adnexae, the lesions also played a significant role in other, secondary disturbances and losses. Due to their impaired vision, the animals were unable to eat and drink with resultant weight loss, loss of egg production secondary infections. The Gram negative, aerobic - facultative anaerobic pathogens that were isolated from the conjunctivae of affected animals proved to be Yersinia pseudotuberculosis bacteria after a classical examination of their biochemical characteristics and their investigation with the ATB ID 32 test kit. In the following an experiment was conducted in which animals free of the pathogen were infected with 0.1 ml of a suspension containing the isolated bacteria at a concentration of 0,5 McF applied onto the left conjunctiva (group 1) or onto the left conjunctiva and into the nasal opening (group 2). Two intact animals were placed into both treatment groups as contact controls. The control group consisted of five intact animals that were kept isolated from both treatment groups. Two-three days following infection the left conjunctiva became reddened in both treatment groups, the animals flickered their lids, there was epiphora and pruritus of the eye. Later fibrinous exudate appeared closing the lids. The symptoms appeared in the non-treated eye with a lag of a few days and they were less severe. None of the birds died or became completely blind during the experiment. There was mostly a pure population of Yersinia pseudotuberculosis bacteria morphologically and biochemically identical to the ones used to infect the animals isolated from clinically affected eyes or, in a few cases, their population was mixed with streptococci. There were no lesions detected in either the contact control or the control animals and bacteriological examinations were also negative.
