An outbreak of an epidemic disease occurred in a specified-pathogen-free (SPF) breeding colony of rats. The clinical signs and the post-mortem findings were characteristic for Tyzzer's disease. The causative agent, Bacillus piliformis, was demonstrated microscopically in ileum, liver and myocardium, and transmitted to mice where its pathogenicity appeared to be similar to that of another strain isolated from mice. B. piliformis from spontaneously-infected rats was demonstrated by indirect immunofluorescence technique. By means of the same technique it was found that the fluorescence antibody titre obtained of the individual sera from spontaneously-infected mice, rats and rabbits was the same, whether the antigen employed was organisms isolated from rats or mice. By testing sera from healthy rats in 3 different colonies by use of immunofluorescence technique, antibodies were found in several sera.

Inverse Pattern

AbstractThe use of an indirect immunofluorescence technique demonstrated that serum from reindeer, Rangifer tarandus tarandus, infected with Elaphostrongylus rangiferi (Nematoda, Metastrongyloidea) contained antibodies directed against antigen(s) on the cuticle of the parasites first-stage larvae (LI). Output of LI from the male reindeer was low in the period June to August, but increased to a higher level during the rutting season (September to October). The titre of specific antibody showed an inverse pattern. In the female reindeer, larval output remained high throughout the sampling period from January to July. During this period antibody titre was low. A relationship between stress (rutting season or calving period), immunity and larval output is suggested.

Post Mortem Findings

Potomac horse fever was reproduced in 15 ponies by transfusion of whole blood originally from two natural cases and subsequently from ponies infected by the transfusions. Incubation periods varied from 9 to 15 days. Affected ponies developed varying degrees of fever, diarrhea, anorexia, depression, and leukopenia. Eleven affected ponies were killed, three died in the acute phase of the disease, and one did not show clinical signs. The most consistent post-mortem findings were fluid contents in the cecum and large colon, and areas of hyperemia (of inconstant degree and distribution) in mucosae of both small and large intestines. Multifocal areas of necrosis occurred in mucous membranes. Ehrlichial organisms were most common in the cytoplasm of epithelial cells, macrophages, and mast cells of the large colon.

Post Mortem Findings

During an explosive outbreak of fatal enteropathic disease involving Clostridium perfringens iota (i) toxin. a total of 183 deaths occurred in 18 weeks. The clinical signs and post-mortem findings are reported. Examinations for virus, Bacillus piliformis and coccidia were negative. Clostridium perfringens i toxin was detected in 22 of 27 animals examined (81·5%), but clostridia were not isolated. Various treatments wcre attempted. It is concluded that i toxin and the syndrome described are closely related.

Pig Husbandry

The health and welfare of pigs was evaluated on the basis of the data on patho-anatomic findings obtained during the veterinary examination of pigs slaughtered in slaughterhouses in the Czech Republic in the period from 2010 to 2017. High numbers of lesions in organs found especially in lungs (finisher pigs 41%, sows 24% and piglets 52%), kidneys (finisher pigs 14%, sows 32% and piglets 15%) and liver (finisher pigs 12%, sows 18% and piglets 19 %) indicate impaired health and welfare of pigs transported for slaughter. The differences in the number of findings between finisher pigs, sows and piglets were statistically significant (p < 0.001). The character of most findings was chronic, which document health and welfare problems occurring on farms as a result of the current pig husbandry. However, acute findings were also detected and indicated processes occurring shortly before and during transport to the slaughterhouse. An important finding is the incidence of parasitic lesions in the liver in finisher pigs (finisher pigs 4%, sows 1% and piglets 1%) that documents persistent occurrence of parasitic invasions on pig farms. Findings of traumatic lesions on limbs in sows and piglets (finisher pigs 0.08%, sows 0.14% and piglets 0.15%) are far below the frequency of the findings in organs; however, their incidence should be further reduced by adjusting the technology of housing, transport and handling. In conclusion, the level of health and related welfare of pigs based on the assessment of post mortem findings in the slaughterhouses vary. Overall, the worst situation is in piglets, followed by sows and the best evaluated are finisher pigs. Post mortem inspection revealed significant numbers of patho-anatomic changes even in pigs considered fit to be transported to the slaughterhouse and slaughtered for human consumption. It is clear that there is still a considerable space for improving the level of health and welfare of the individual categories of pigs.

A survey of aldicarb poisoning in companion animals was conducted by posting questionnaires to all private practitioners in Gauteng Province, South Africa. The survey was designed to determine the percentage of aldicarb cases seen, treatment regimen, clinical signs observed, proposals for preventative actions and more effective treatments. Other questions included duration of treatment, survival rate, cost to clients, post mortem findings and reasons for poisonings

Chocolate intoxication in small animals may be life-threatening and associated with serious morbidity and mortality.&nbsp;The main clinical presentations are cardio-respiratory and neurological complications. One of the most common post-mortem findings is pulmonary oedema which can be a cause of immediate death.&nbsp;We report a case of non-cardiogenic pulmonary oedema thought to be triggered by chocolate intoxication in a three-month-old puppy Dachshund dog. To the authors&rsquo; knowledge this is the first time such a complication has been reported after chocolate ingestion. The history, clinical signs, diagnostic approach (radiographs, methylxanthine concentrations, electrocardiography and echocardiography), and treatment are described. The effects of a combination of methylxanthines and other triggers of non-cardiogenic pulmonary oedema are discussed. &nbsp; &nbsp;

Haemorrhagic Diarrhoea

An outbreak of coccidiosis was reported in a pig farm housing four boars, six sows, twenty one growers and eleven piglets. Eleven neonatal piglets in two litters of three and five days old were suspected to be involved. Three (27%) out of eleven piglets presented signs of profuse foul smelling diarrhoea and pyrexia, while there was haemorrhagic diarrhoea in one and mortality was 9%. A diagnosis of coccidiosis was made based on the clinical signs, post mortem findings of ulceration and fibrinonecrotic enteritis and laboratory identification of 4,600 coccidial oocysts per gramme of faeces by Mc Master counting technique which were identified as Isospora suis. The two herds were treated with Tripple sulfa-Trim® in drinking water for three days. This medication was effective as the diarrhoea resolved within four days of its onset

Oedema Disease

From a group of 11 recently weaned pigs, 4 were reported to be sick. Clinical examination of the sick pigs revealed marked dyspnoea, bluish-red discolouration of the skin, incoordination and difficulty in walking. Bacteriological examination of the gut contents of 2 pigs that had died earlier yielded pure cultures of haemolytic Escherichia coli. Post mortem examination of the remaining 2 pigs that died subsequently revealed progressive pulmonary collapse. One of these also showed subcutaneous oedema of the head and marked oedema of the mesentery of the spiral colon and oedema of the brain. Microscopically there was pulmonary alveolar collapse and degenerative changes in the liver.On the basis of the clinical signs, isolation of haemolytic E. coli and the post mortem findings, a diagnosis of oedema disease was made.
