A fluid adjuvanted vaccine consisting of inactivated hepatitis virus (iH) and leptospirae antigens (L) was developed. The vaccine (Kavak iHL; Duphar) was tested in several vaccination programmes both alone and in combination with freeze dried measles (M) or distemper (D) vaccines. The results demonstrate that this new vaccine is also effective in pups with maternally derived antibodies, although a second vaccination at 14 weeks of age is recommended to boost the first vaccination. For the booster vaccination either the iHL-vaccine or the liver attenuated hepatitis vaccine (H) can be used.

Egg-attenuated duck hepatitis type (Rispens H55) was exhaustively tested as a potential vaccine under controlled conditions in ducklings fully susceptible to the disease at day 2 after hatching. Data are presented which indicate that this vaccine fulfils essential criteria of efficacy in terms of (a) the optimal age at which successful vaccination is practicable (day 2 or earlier), (b) the rapidity of onset of immunity (in 48 to 72 hours), (c) the high level of immunity induced (88.0 to 94.0 per cent), (d) the persistence of this degree of immunity in the individual bird throughout the period when it would otherwise be at risk (until the end of the fourth week of life) and (e) the consistency of the effects of the vaccine in successive groups of ducklings hatched over a four year period. Employed as a vaccine. H55 was completely innocuous to the vaccinated ducklings under laboratory conditions.

Serum specimens from 42 normal dogs and 42 with untreated malignant tumours were assayed for the presence of antibodies to human adenovirus types 5, 21 and 31 and to infectious canine hepatitis (ICH) virus. Radioimmunoassays using human adenovirus antigens showed that 71 per cent (30/42) of all dogs with tumours, but only 19 per cent (8/42) of all normal dogs, were positive for human adenovirus antibody. Canine sera reactive with antigens of one human adenovirus type in radioimmunoassays were also reactive with antigens of the other two types. Dogs bearing malignant lymphoma or squamous cell carcinoma tumours had higher levels of antibody against adenovirus type 5 antigens. Human adenovirus type 5 was neutralised by sera from four tumour-bearing and two normal dogs, while sera from two normal and five tumour-bearing dogs were positive in immunodiffusion tests with human adenovirus antigens. Levels of ICH antibody in sera of normal adult dogs and adult dogs with tumours were not markedly different when measured by radioimmunoassays. Likewise, sera from these two groups of dogs had similar ranges of ICH neutralising antibody titres. In contrast, levels of ICH antibody detected by the serological assays in sera from non-pet, non-vaccinated pups were either markedly low or absent. Possible explanations for the observed increased levels of human adenovirus antibody in sera of tumour-bearing canine pets are discussed.

The safety of three attenuated virus vaccines of proven efficacy against duck virus hepatitis was assessed by controlled laboratory studies which involved the serial transmission of the virus through groups of two-day-old ducklings known to be susceptible to the disease. Each vaccine was initially derived from a different source. Enhancement of virulence which resulted in deaths from the disease in test groups of ducklings occurred in each instance.

A serological survey of growing pigs from farms throughout Great Britain revealed that antibodies to toxocara and ascaris larval antigens were present in 4.5 per cent and 39.3 per cent respectively. Heavy infection with toxocara occurred only rarely and it is considered that this parasite is unlikely to be an important cause of chronic focal interstitial hepatitis. Antibodies to both nematodes were detected more frequently in heavy hogs than in pigs of lighter weight. Reginal differences in the prevalence of antibodies were also observed.

Pheyntoin (Epanutin: Parke, Davis) is widely used for the control of chronic convulsive disorders in the dog because it exerts an anti-epileptic effect without causing general depression of the central nervous system. To our knowledge fatal cases of phenytoin sensitivity in the dog have not been reported. A case is described in which hepatitis, jaundice and death followed the administration of the drug.

During a period of seven months in 1982-83 cases of postvaccinal encephalitis were recorded in dogs in various parts of Britain after the administration of a particular batch of combined distemper/hepatitis vaccine. Detailed investigations of one of these cases revealed that the distemper component was responsible and the vaccine virus was recovered from the brain of an affected dog.

There is a hepatitis of dogs which occurs in acute, persistent and chronic forms. Histological studies of spontaneous cases suggested that several apparently diverse hepatic diseases might be stages of one process. This was also implied by follow up studies and case histories: acute non-lethal episodes were followed later by the development of chronic hepatitis, cirrhosis and liver failure. Serum was taken and homogenates of liver were made from three field cases representing different putative temporal stages of the complex. These were injected into experimental dogs and a hepatitis was induced in all. The cytopathological and histological changes were the same in all animals and were identical to field cases. Acute lethal disease and persistent infections were produced. Two second passages were carried out and an identical condition was induced, characterised by recurrent episodes of subclinical hepatitis and persistent infection. It is suggested that the disease might be named canine acidophil cell hepatitis in view of the pathognomonic cytopathology. Specific morphological criteria have been established for this hepatitis.

Levels of passively transferred maternal antibodies to three canine viruses, rabies virus (RV), canine distemper virus (CDV) and infectious canine hepatitis (ICH) virus, in serum specimens from 14 fetal pups and in serial serum specimens collected up to 45 days after whelping from 14 neonate pups were compared with levels of antibodies to these viruses in milk and sera collected concurrently from their respective dams. Radioimmunoassays using RV-, CDV- and ICH virus-specific antigens showed that sera from all fetal pups had detectable levels of antibodies to all three canine viruses and ICH neutralising antibodies were detected in sera from 10 of the 14 fetal pups. As the time after whelping increased, titres of RV-, CDV- and ICH virus antibodies measured by radioimmunoassay and ICH virus neutralising antibody tests in serially collected specimens of milk from dams rapidly decreased, while titres of the antibodies in serum specimens from newborn pups in their litters steadily decreased. Individual fetal and newborn pups with a high titre of antibody to one virus also had high titres to the other two viruses, although a wide range of titres was observed among pups in each of the litters studied. Markedly higher titres of antibody to all three viruses were observed in serially collected specimens of sera from dams than in sera from fetal and newborn pups in their litters. Results show that maternal RV, CDV and ICH virus antibodies are transferred from dams to pups in utero and by nursing. Levels of these maternal virus-specific antibodies in newborn pup sera decreased at similar rates as time after whelping increased.

A mortality survey was carried out on three flocks of broiler chickens on a Victorian grower farm. A total of 61,400 chicks were placed and 2883 (4.7 per cent) died or were culled during rearing. Only 1028 (36 per cent) dead and culled birds were available for autopsy and interpretation was based on figures extrapolated from the findings. The most common condition encountered was death in good condition associated with congestion of the lungs (39 per cent of chickens autopsied). Inclusion body hepatitis was diagnosed in 30 per cent of chickens over 21 days of age which died. Mortality during the first 10 days was 1.1 per cent of chicks placed. The incidence of various other conditions is presented with relevant observations and comments.
