Live and killed virus vaccines: their use against the respiratory diseases of cattle.

The respiratory diseases of cattle are due to a combination of different factors among which figures a viral infection. The antiviral vaccination, perfectly possible owing to associated killed vaccines and live virus, is thus a very important element which must enter into every general plan of prophylaxis. Moreover, these plans will concern bacterial infections, conditions of rearing, etc. We have demonstrated that it is possible to produce good immunity in calves and sheep using a trivalent killed vaccine (parainfluenza 3, adenovirus 3 and reovirus 1). Possible interference with antibodies of maternal origin makes the multiplication of vaccine injections desirable.

Intraaticular treatment of tarsal degenerative joint disease in cattle.

Tarsal degenerative joint disease (DJD) in 12 cattle was classified as primary or secondary, based on age, evidence of hereditary or congenital joint conformation defects, faulty hindlimb alignment, duration and type of usage joints were subjected to, and history or signs of repeated trauma. Three of the cattle had bilateral primary tarsal DJD, 7 had bilateral secondary tarsal DJD, and 2 had secondary DJD of the left tarsus. Analyses of synovial fluid samples provided a means of characterizing pathologic changes of tarsal DJD, Results of blood and synovial fluid analyses were grouped in compilation of data for cattle affected with either primary or secondary tarsal DJD. Corticosteroids and a long-acting synthetic progestational agent were injected singly or in combination with aqueous antibiotics into affected tarsal joints. Tarsal joints of 5 of the cattle responded favorably to a single intraarticular treatment, as manifested by palliative relief and functionally usable joints. Seven joints of 5 cattle were subjected to repeated intraarticular treatment. Serial synovial fluid analyses in 7 of the cattle provided a means of assessing tarsal joint response to intraarticular treatment or to therapeutic arthrocentesis, exclusive of patient objective response. One cow developed a mild self-limiting bilateral postinjection synovitis that was resolved after the 2nd and final intraarticular injection. Usable function returned to tarsal joints of cattle that responded favorably to intraarticular treatment at different periods after single or repeated injections. Three cattle with advanced tarsal DJD experienced minor temporary relief and were euthanatized at their owner's request. Improvement did not occur in the tarsal joint of 1 cow subjected to therapeutic aspiration only. Intraarticular treatment in all cattle was considered supportive to the animal's well-being rather than curative.

Slaughterhouse condemnations for hind leg disease in cattle.

Hindlimb condemnations occurred in 0-11 per cent (194/173,580) of all cattle at a large Scottish slaughterhouse over a 22-month period. Cows and bulls were more frequently involved than steers or heifers. Gross pathology, studied in 42 cattle (21 per cent of the total condemned), revealed osteoarthritis of the stifle and hip respectively in 19 and 16 cases. The traumatic lesions included meniscal damage, anterior and other ligamentous rupture. The UK loss from such condemnation is estimated at over pounds200,000 in January 1977.

Diagnosis of Johne's disease in cattle: a comparison of five serological tests under field conditions.

Sera from 775 adult milking cattle on 13 farms in Friesland and from 359 of the same cattle taken during the following year, were examined for evidence of infection with M johnei by the complement fixation, fluorescent antibody, haemagglutination, haemagglutination-lysis and immunodiffusion tests. Eighteen animals, not clinically affected but which had serologically positive tests were slaughtered and M johnei was isolated in cultures from 16. The fluorescent antibody test was as sensitive as the complement fixation test. The other tests were relatively insensitive and would only be of value as confirmatory tests in the presence of reactions to the first two tests. It is concluded that the use of the fluorescent antibody and the complement fixation test together was of value in detecting sub-clinical Mycobacterium johnei infection.
