Sixty cattle (12 first season and 48 second season grazing animals) were allocated to three groups according to age and bodyweight. Each group was divided into "control" and "treated" subgroups. Before turnout, a morantel sustained release bolus (MSRB) was administered to each animal in the "treated" category. The groups were moved from field to field according to the farmer's normal rotational grazing policy. Each field was, however, divided into two equal halves, one of which was reserved for the MSRB treated cattle, while the other was used exclusively for the controls. Severe parasitic gastroenteritis occurred in the first season controls during early September, while milder disease affected the untreated animals in the smaller of the second season groups. No gastrointestinal disease was apparent in the corresponding MSRB treated cattle. A mild outbreak of parasitic bronchitis occurred in the first year controls during October; there was evidence of less sever lungworm infection in the matching MSRB treated animals. The larger second season group showed no signs of parasitic disease.

Outbreaks of transmissible gastroenteritis in 56 breeding units, six maiden gilt sites and 64 fattening units were investigated during the period December 1980 to October 1981. The disease invariably occurred in classical virulent form, resulting in very high mortality in baby piglets. Reproductive sequelae were sometimes evident. Individual outbreaks continued for longer than in previous years. There was a high rate of recrudescene, particularly in large breeding units, and infection also persisted in many fattening units. The value of control measures and supportive therapy is discussed.

A questionnaire sent to all veterinary practitioners in Australia and many in New Zealand asking for details of their experience with canine parvovirus infections in 1980 elicited the following information. In 1980 explosive outbreaks of disease occurred in most parts of Australia. There was no obvious pattern of spread over the continent as a whole. In many cases outbreaks in country areas occurred after dog shows. Canine parvovirus enteritis affected all age groups with an overall mortality of 16 per cent. While the death rate in the young was high, most dogs responded well to fluid therapy. Canine parvovirus did not appear to be associated with clinical entities other than gastroenteritis and myocarditis. No connection with reproductive problems was established. Killed canine parvovirus vaccines were used extensively after the initial release for sale in July 1980. The vaccines appeared to be safe and effective at least in the short term. Problems arose only in vaccination of very young animals.

A three year survey on sheep deaths and their causes was conducted on 10 commercial farms in the north of Scotland. Diseases and other trauma associated with the perinatal period accounted for 56.81% of all ewe deaths, while pneumonia, parasitic gastroenteritis, torsion of the bowel and haemorrhagic enteritis (redgut) accounted for a further 21.7%. No one disease condition predominated in the rams and hoggs. In lambs, most deaths occurred between birth and four days old (77.86%). Causes came in the form of starvation and exposure (34.2%), stillbirths (18.2%), lambing injuries (11.06%), infectious conditions (8.0%), dystocia (7.6%) and abortion (5.2%). The overall death rate among the lambs was 14.2%.

Intravenous gelatin given as a plasma substitute to cases of road traffic accidents, cystic endometritis and haemorrhagic gastroenteritis appeared to enhance the chances of recovery. Method, rate, volume and temperature of administration was not apparently critical. There seemed to be no other pharmacological interaction with other drugs or replacement fluids using gelatin.

Two groups of 16 set-stocked calves were used to evaluate a new strategy for the prevention of parasitic bronchitis and parasitic gastroenteritis. One group was left untreated while the calves in the other were treated with abamectin at 0.2 mg/kg at turnout and again six weeks later. The treatment prevented the output of nematode eggs and lungworm larvae in faeces for at least 70 days. The number of infective larvae subsequently appearing on the pasture was reduced by 90.2 per cent and the infectivity of the pasture (as monitored by tracer calves) by 96.0 to 99.8 per cent in the case of Dictyocaulus viviparus, 88.2 to 99.2 per cent for Ostertagia ostertagi and 69.3 to 98.1 per cent for Cooperia oncophora. Parasitic bronchitis occurred in the control calves and both bronchitis and gastroenteritis in the tracer calves grazing the paddock grazed by the control calves, but no disease occurred either in any of the calves treated with abamectin or in the tracer calves grazing the paddock grazed by these calves.

One hundred and twenty four-month-old Hereford-Friesian cross heifers weighing from 88 to 130 kg were divided into two equal groups. One group acted as a control with each animal receiving one placebo bolus, the other animals received one prototype intraruminal sustained-release bolus designed to deliver approximately 8 mg ivermectin/day for 100 to 120 days. The boluses were administered the day before turnout in mid-May. Each group was grazed separately for 167 days on pastures contaminated with parasitic nematode larvae including the lungworm Dictyocaulus viviparus, and the gastrointestinal worms Ostertagia ostertagi, Cooperia oncophora and Nematodirus helvetianus. Parasitic disease did not occur in the ivermectin-bolus group, but the control group required anthelmintic treatment to control parasitic gastroenteritis at 111 and 154 days after turnout. Up to the 111th day after turnout, the peak mean nematode egg and larval counts per gram of faeces in controls was, respectively, 564 epg and 0.5 lpg. Based on faecal nematode egg counts and worm burdens in bolus-treated cattle removed from pasture at 119 days after turnout and bolus function studies, it was concluded that ivermectin delivery from the prototype bolus ceased between 95 and 98 days after administration. However, unlike the controls, the treated cattle did not develop parasitic gastroenteritis at any time. Their faecal nematode egg output was significantly (P < 0.01) lower (< 1 epg) compared to the controls and lungworm larval output zero during the functional life of the bolus. The faecal egg and larval outputs continued low until the end of the trial.(ABSTRACT TRUNCATED AT 250 WORDS)

The prevalence of infections with H1N1- and H3N2-influenza viruses, porcine respiratory coronavirus (PRCV), transmissible gastroenteritis virus (TGEV) and porcine epidemic diarrhoea virus (PEDV) in feeder pigs shortly after their entry into fattening units was examined. Ten groups of pigs with acute respiratory disease during the months September to October 1991 and seven groups of pigs with acute diarrhoea during the months February to March 1992 were investigated. On arrival in the fattening herds, more of the pigs were negative for antibodies against H1N1-influenza virus and against PRCV during September to October (61 and 50 per cent, respectively) than in February to March (51 and 34 per cent, respectively). There was serological evidence of a triple infection with PRCV and both influenza viruses in seven of the 17 groups; dual infections with PRCV and H1N1-influenza virus occurred in nine groups and with H1N1- and H3N2-influenza viruses in one group. Seroconversion against TGEV was not detected in any of the 17 groups, but seven of them had seroconverted to PEDV. Multiple infections with PRCV and either one or both of the influenza viruses were thus very common shortly after the introduction of feeder pigs into the fattening herds. There was no association between the type and/or multiplicity of these infections and respiratory disease, but infections with PEDV were clearly associated with outbreaks of diarrhoea.

In the Murcia region of south east Spain, epidemics of transmissible gastroenteritis-like disease have occurred in pigs every three years since 1980. In 1987 a sero-epidemiological survey was conducted to estimate the prevalence and spread of transmissible gastroenteritis virus (TGEV) infection among breeding pigs and farms, and to determine any association between the infection and herd size and geographical zone. The Murcia region was divided into four geographical zones and the farms were classified by size into four categories. The random sample was statistically representative of both the breeding stock and the farms in each geographical zone, and the analyses involved 6000 breeding pigs from 480 farms. The immunological techniques employed were the indirect ELISA and the blocking ELISA. The prevalence of seropositive breeding pigs was 1.27 +/- 0.28 per cent and the prevalence of infected farms was 5 +/- 1.94 per cent. On the infected farms, the prevalence of seropositive pigs ranged from 5 to 60 per cent. The infection occurred throughout the Murcia region, but a significant association (P < 0.01) was observed between the geographical zone and the prevalence of TGEV infection. Herds with > or = 50 breeding pigs had a greater prevalence (P < 0.01) of TGEV infection.

Doramectin was used in a strategic programme for the prevention of parasitic gastroenteritis in first season grazing calves. Three groups of nine calves were used: group 1 was left untreated, group 2 was treated with doramectin at 0.2 mg/kg at turnout and again eight weeks later, and group 3 was treated with 0.2 mg/kg ivermectin at three, eight and 13 weeks after turnout. Both treatment programmes prevented the gastroenteritis which occurred in the controls. The growth rates of the treated calves were superior, and their faecal egg output, and serum pepsinogen and gastrin concentrations were all substantially lower than those of the control calves. The numbers of Ostertagia species larvae on the pastures grazed by the treated calves were also lower than on the pastures grazed by the control calves.
