Gross and microscopic lesions of Bolivian hemorrhagic fever (BHF) are described in 10 rhesus monkeys that survived from 30 to 78 days after subcutaneous inoculation with a dose of 10(3) plaque-forming units (PFU) of Machupo virus, a dose which produces a severe and generally fatal disease. Six of the monkeys had been given low doses of homologous immune globulin when initial signs of infection appeared. Monkeys exhibited clinical signs in two phases. The initial signs of acute infection which began to appear about 1 week following inoculation included: diarrhea, depression, anorexia, dehydration, and skin rash. The survivors of this early phase of the illness usually showed improvement before relapsing into the second (or chronic) phase, which was characterized clinically by central nervous system disturbances including incoordination, tremors, convulsions, paresis, and muscle atrophy. Microscopic lesions were similar in both immune globulin-treated and untreated animals. These included widespread lymphoreticular infiltrates in the walls and adventitia of blood vessels of the brain, spinal cord, pancreas, intestine, liver kidney, adrenal, parathyroid, heart, and skeletal muscle. Diffuse lymphocytic infiltrates not confined to the vascular or perivascular tissues were present to a variable degree in many of these and other organs. Several monkeys exhibited lymphocytic inflammation of the choroid, meninges, peripheral nerves, and ganglia.

In the course of multiple episodes of thiamine deficiency in the rhesus monkey, the triad of anorexia, apathy, and hind limb weakness is the earliest clinical manifestation. In later episodes, nystagmus, abducens paresis, midline ataxia, dysmetria, and congestive heart failure are also seen. With the exception of dysmetria, the neurologic signs promptly respond to thiamine administration. Pair-fed controls showed no clinical signs. Neither peripheral neuropathy nor edema was observed. Thiamine-deficiency in the experimental animals was confirmed by blood transketolase assays.

The mercury levels in 69 muscle samples from fish weighing from 0.3 to 200 kg caught in Moreton Bay, Queensland, in the latter half of 1976 ranged from less than 10 to 2,030 ng/g. Mercury levels in blood samples from 53 humans and 100 dogs in Brisbane almost all contained less than 10 ng/ml while the level in 162 cats sampled ranged from less than 10 to 329 ng/ml. Chronic methylmercurialism developed in 2 cats dosed daily with methylmercury, bound to cysteine, at the rate of 0.6 mg/kg body weight for 74 and 77 days respectively. Terminal clinical signs included anorexia, weight loss, knuckling over at the carpus and tarsus, hypermetria initially involving the forelegs and later the hindlegs, sluggish reflexes, paresis involving all limbs, persistent crying, apparent blindness, tonic and clonic convulsions and salivation. Pathological changes were confined to the nervous system and included degeneration of neurones and perivascular cuffing in the cerebrocortical grey matter, focal atrophy of the granular layer, focal spongiosus of the molecular layer and degeneration and loss of Purkinje cells in the cerebellum and demyelination in the fibre tracts of the dorsal funiculus, mainly the fasciculus cuneatus and in the lateral and ventral corticospinal tracts. Terminal blood methylmercury levels were in excess of 18 microgram/ml, while brain methylmercury levels ranged from 21.0 to 28.4 microgram/g. The liver and kidney contained the highest total levels of mercury of 50 to 80 microgram/g, of which 23 to 37% was inorganic.

The paper reports on a 5 year old boy showing a sprawling haemangioma racemosum of the right side of the mediastinum. The vascular tumor is fed by a tortuous A. thoracica interna dextra and numerous arterial vessels arising from the right subclavian artery and from the aorta including the right coronary artery and branches from the abdominal aorta. The child presents also paresis of the right diaphragm probably secondary to the pressure of the pulsatile tumore along the course of the phrenic nerve. After ligation of three major feeding arteries the continuous murmur disappeared and fatigability and anorexia became less. Apart from this report a review of the literature on vascular malformations of the arterio-venous fistula type within the thorax sums up the most important features of these vascular anomalies: haemodynamics, localisation, clinical signs, therapy, natural history, therapy and etiology.

The literature contains about 500 cases of equine leucosis, though the reports are deposited in a great number of journals and vary considerably concerning particular topics. During the last years there has been a remarkable increase of publications about this syndrome in the equine. The clinical leucosis key recommended by us has been confirmed in principle considering the latest literature. In about 70 individual symptoms which can be clinically observed in equine with leucosis 11 can be considered as main symptoms because of their frequency; they are again classified in primary (lymph node tumours including splenomegaly--loss of condition, weakness--cachexia, weight loss, periphery oedema), secondary (anorexia, inappetence--fever--paleness of mucous membrane--anaemia--tachycardia) and accessory (incoordination--tachypnoea, dyspnoea--apathy, lethargy) main symptoms. Furthermore in future it will be necessary to take into more consideration the symptoms "recurrent colic" and "hydrothorax" within differential diagnosis. The main symptom "incoordination" (ataxia, asynergy, paresis, paralysis) is used by us more precisely only in case of impairment of nervous system by neoplastic infiltrations and does not signify as possible symptoms of general physical weakness, for example faltering, staggering, tumbling or lameness. The morphological classification follows further on our previous recommendation. There exist generalized forms with tumour infiltrations in abdominal and in thoracic cavity as well as especially in peripheral lymph nodes. On the other hand there are characteristic manifestations in certain regions of the body, which establish distinctly the clinical symptomatology. They are marked as regional multicentric forms with the main localizations "mediastinal", "splenic", "mesenteric" or "intestinal".(ABSTRACT TRUNCATED AT 250 WORDS)

Daily doses of 6-aminonicotinamide (3-5 mg/kg) given by ip injection produced ataxia of the hind limbs progressing to an ascending paresis/paralysis, anorexia, diarrhoea and death in male and female New Zealand White and Dutch Belted rabbits. At autopsy, caecal and gastric distention were seen and the apex of the gall bladder had necrotic foci. Light microscopic lesions included atrophy and necrosis of the white lobe of Harder's gland and atrophy of seminiferous tubules with cellular necrosis, vacuolation and the presence of multinucleated giant cells. Cytoplasmic vacuolation was observed in epithelial cells from many tissues, usually in the basal portion of the cells. Vacuolation of the epithelium of the sacculus rotundus and vermiform appendix was found within the same time frame as histiocytic hyperplasia in these organs. Spongiosis and gliosis were seen in certain parts of the central nervous system. Ultrastructural alterations in the gall bladder epithelium consisted of distention of intercellular space, mild distention of perinuclear space and coalescing, intracytoplasmic, membrane-bound vacuoles, a few of which contained membranous debris. Some alterations of 6-aminonicotinamide toxicosis were prevented by simultaneous administration of nicotinamide with 6-aminonicotinamide.

The effects in goats of the subcutaneous injection of varying doses of Pseudomonas pseudomallei (90 to 500,000 bacilli) suspended in normal saline are described. High doses (greater than or equal to 500 bacilli) caused acute, fatal infections. Lower doses (90 to 225 bacilli) caused acute or chronic disease when infection became established. However, 11 of 18 goats injected with the lower doses of bacilli showed no sign of infection on clinical or bacteriological examination. Response to antibiotic therapy with long acting tetracycline and chloramphenicol was minimal. Goats surviving the initial phase of infection tended to overcome the disease with a corresponding increase in the number of abscesses that were sterile at necropsy. In infected goats, clinical signs included undulating fever, wasting, anorexia, paresis of the hind legs, severe mastitis and abortion. At necropsy, abscesses were found predominantly in the spleen, lungs, subcutaneous injection site and its draining lymph node.

T-2 toxin at 0 or 15 mg/kg in 0.75 ml dimethyl sulfoxide was topically applied to 11- to 12-week-old specific-pathogen-free derived crossbred female pigs. Animals were killed on Days 1, 3, 7, or 14 after treatment. Clinical signs and morphologic changes in the skin and internal organs, as well as the residual concentrations of T-2 toxin and its metabolites in plasma, bile, urine, skin, and subcutaneous tissue, were examined. The T-2-treated pigs had signs of lethargy, anorexia, posterior weakness or paresis, and persistent fever. The skin at the site of application was red and swollen initially and progressively became dark red and then purple. By Day 7, at the margin of the exposed area, clefts had formed and were covered by serosanguinous exudate. By Day 14, the affected skin was focally separated from the underlying tissue and covered by a thick scab. The initial skin lesions were characterized as a spongiotic dermatitis and were located mainly in the dermal papillae and stratum germinativum of the epidermis. These lesions progressed to a locally extensive necrotizing dermatitis between Days 3 and 7 that was still evident at Day 14. Healing began on Day 7 and was more prominent on Day 14. Morphologic changes in the internal organs were minimal. They consisted of necrosis of single cells in the follicles of lymphoid tissues and in the exocrine pancreas.(ABSTRACT TRUNCATED AT 250 WORDS)

T-2 toxin at 0 (6 pigs) or 15 mg/kg (8 pigs) in 0.75 ml of dimethyl sulfoxide was topically applied to 9- to 10-week-old, male castrated, specific-pathogen-free derived pigs which were immunized subcutaneously with sheep red blood cells (SRBC) on Days 0 and 21. Whole blood and serum samples were taken periodically for clinical pathologic and immunologic evaluations. The pigs were observed daily and weighed weekly; their rectal temperatures were measured periodically. The T-2-treated pigs displayed anorexia, lethargy, posterior weakness and paresis, persistent high fever, and reduced body weight gain. Prominent neutrophilia, decreased serum glucose, albumin, and alkaline phosphatase activity, and increased serum globulin were seen in the T-2-treated group. The responses of enriched peripheral blood mononuclear cells to mitogens concanavalin A, phytohemagglutinin, and pokeweed mitogen of the T-2-treated group were significantly lower than those of the control group both at early (3 to 5 days) and late (20 to 28 days) postdosing intervals. No significant effects were noted in the hemagglutination titer to SRBC. Thus, in addition to the severe local dermal injury reported previously, topical exposure of swine to a sublethal dose of T-2 toxin, 15 mg/kg, can cause significant systemic effects on parameters such as body weight gain, rectal temperature, hematology, serum biochemistry, and cellular immune response.

Clinical findings for 5 new cases of colonic perforation in corticosteroid-treated dogs were presented and 8 other cases from the literature were reviewed. Colonic perforation was a fatal complication in all 13 dogs, 12 of which had had recent major surgery. Ten dogs were neurosurgical patients, 1 dog received medical therapy for head trauma and nonambulatory paresis, and 2 dogs were operated on for non-neurologic conditions. Dexamethasone was the most frequently used corticosteroid, and 12 dogs received a mean cumulative dose of 6.4 mg/kg over an average period of 5.1 days. Depression, anorexia, and emesis, the most frequent signs attending colonic perforation, became evident 3 to 8 days after surgery. Signs preceded death by an average of 22.3 hours. Correct antemortem diagnosis (5 dogs) and surgical intervention (3 dogs) had no effect on eventual outcome (mortality = 100%). Colonic perforation most frequently developed in the proximal descending portion and always involved the antimesenteric border. Gross fecal contamination of the peritoneal cavity and acute generalized peritonitis were evident in all but one dog. Adhesions were observed at the lesion site in 6 dogs, but prevented gross soilage in only one dog.
