“…A recent report of reduced production in commercial laying flocks supports this observation (Schwartz et al, 1976). The production of fertile eggs was obviously affected by the virus infection and fertile eggs were never obtained from the dual-infected birds.…”

SUMMARYOne group of embryonated chicken eggs was inoculated with sterile mycoplasma broth and another with a broth culture of Mycoplasma synoviae. Each group was subdivided into two and the chicks were hatched in four isolation pens. At 1 day of age one uninfected and one M. synoviae infected group were inoculated with a reovirus known to cause tenosynovitis. Birds were closely observed, and some were killed for sampling as chicks (1-5 weeks) and the remainder as adults (25-30 weeks). Clinical signs related to both organisms were seen in the dual-infected chicks and were more pronounced than in either of the corresponding single infections. There were significant weight differences between the infected and control chicks, except in single M. synoviae infection, and the mean weight of the birds with mixed infection was less than those with either single infection. Gross and histological lesions were observed in the hocks and livers of chicks in each infected group although with a higher incidence and severity in the dual-infection. Microscopic lesions were seen in the hearts of some birds in all three groups. Leg lesions associated with the reovirus infection persisted to maturity and another observation in mature, virus-infected birds was impaired egg production and fertility.

“…Information was usefully summarised by Olson (1975) who stated that the condition was restricted to meat-type birds. However, the disease has now been described in commercial White Leghorn chickens in Pennsylvania (Schwartz et al, 1976) and in a recent review, van der Heide (1977) briefly refers to the disease in the same breed in California.…”

“…The condition has also been reported in layer breeds (Schwartz et al, 1976). It is generally accepted that tenosynovitis is associated with avian reovirus infection (Olson and Weiss, 1972;Glass et al, 1973;van der Heide, 1977).…”

Bacterial and viral agents associated with tenosynovitis in broiler breeders in Western Australia

SUMMARYThe pathology and infectious agents associated with several outbreaks of clinical tenosynovitis in poultry were investigated. Staphylococcus aureus were recovered from tendon tissue of from 51.9% to 97.8% of affected chickens in different outbreaks of the disease. 5. aureus were also present in the liver and heart blood and were considered to contribute to the high mortality observed following occurrence of clinical tenosynovitis in individual chickens. Bacteria otherthan S. aureus were also recovered but in a much lower proportion of chickens than was S. aureus. Adenoviruses and reoviruses were also recovered from tendon tissue of chickens with a concurrent bacterial infection. Although the pathology observed in clinically affected chickens was suggestive of a bacterial aetiology it is hypothesised that the tenosynovitis outbreaks investigated were due to an early viral infection which normally remained subclinical and that secondary infection with bacteria, particularly S. aureus, was responsible for the development of clinical signs.
