Burkitt's lymphoma (BL) cell lines estimated in a previous study as having a high, low and no tumourigenicity (7) were intravenously (i.v.) injected into preirradiated (480 rad) nude mice. BL cell lines with a high tumourigenic potential produced metastatic tumours in the brain, spinal cord, bone marrow, stomach and kidney, but did not disseminate into the lung, liver, ovary and spleen. The survival time of the tumour bearing animals ranged from 2 to 10 weeks. The majority of mice i.v. injected with highly tumourigenic BL cell lines showed paresis or paralysis of the hind legs. This was associated with the presence of neoplastic nodules either in the brain and/or in the spinal cord. In animals with metastasis to the stomach and kidney progressive cachexia was observed. The described experimental model of metastatic BL tumours in nude mice can effectively be used for the in vivo study of new therapeutic molecules such as monoclonal antibodies coupled or not to substances, toxic to tumour cells. This model can also be useful for the identification and analysis of homing properties of BL cells and their implication in BL pathogenesis.

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)

Ninety outbred white adult female mice were infected with Trypanosoma brucei gambiense (GUMS 2, alias LUMP 1237) originating from a Zairian patient and known to produce a low parasitaemia in rodents. The development of cerebral trypanosomiasis was independent upon the number of parasites inoculated per mouse. Trypanosomes appeared in the circulating blood about four months after infection, when some mice started to show the first signs of paresis which subsequently led to cachexia. A clinical test to stage such a development is described. 57 mice were sacrificed at various intervals after infection, starting from one to 22 months. The morphological changes in the brain consisted of a diffuse meningoencephalitis in 45 mice, (78.9%) often associated with parasites, the latter being best visualised in 21 mice (36.8%) by immunofluorescence using a specific antitrypanosome antibody. The trypanosomes showed a predominantly extravascular distribution in the cerebral parenchyma, to a lesser extent in the meninges and only rarely in the choroid plexuses. Deposits of immunoglobulins in the choroid plexuses and cerebral infiltrations by plasma cells were mild. The level of circulating immune complexes was found to be increased. Adequate intravenous Melarsoprol did not prevent the disease from progressing to advanced stages, and there is limited morphological evidence that it did not eradicate the parasite from the host. The immunofluorescent use of an antitrypanosome antibody to demonstrate the persistence of tissue parasites after chemotherapy is recommended. Murine models seem therefore to be suitable for drug screening in cerebral trypanosomiasis since all three trypanosomes of the brucei group can be adapted to mice.

The mutant strain of Wistar rats carrying an autosomal recessive gene defect is characterized by a sequence of progressively developing behavioural alterations including hyperexcitability, tremor, olfactory and gustatory automatisms, bradykinesia, ataxia, rigidity, paresis and cachexia. The stereotypy and locomotor responses to increasing doses of apomorphine hydrochloride and D-amphetamine sulphate, and the catalepsy response to increasing doses of haloperidol were studied in mutant rats at the age of 6-7 weeks. In the mutants, both the stereotypy and locomotor responses to amphetamine were enhanced, while stereotypy and locomotor effects induced by apomorphine were unaltered. The cataleptic response to haloperidol was significantly diminished compared to controls. These findings indicate a derangement in the function of basal ganglia in the mutants.

Several species of atypical mycobacteria have been isolated from wild and captive amphibians. In captive anurans, cutaneous and visceral mycobacteriosis are common and can result in significant mortality, particularly when animals are immunocompromised. Mycobacterial arthritis and synovitis are reported rarely in amphibians. We describe 20 cases in painted reed frogs (Hyperolius marmoratus), which presented with cachexia, limb paresis or paralysis or 'spindly leg syndrome'. Histopathology revealed multifocal histiocytic to granulomatous synovitis affecting appendicular, rib or spinal intervertebral joints. Periarticular granulomata, granulomatous cellulitis and skeletal muscle atrophy, necrosis and degeneration were also present. In one case, granulomatous spinal osteomyelitis was recorded. Ziehl-Neelsen stains showed large numbers of acid-fast bacteria in macrophages and histiocytes. The mycobacterial isolates obtained from culture were identified as members of the Mycobacterium chelonae complex (either M. chelonae or Mycobacterium abscessus). This was confirmed by 5'-16S ribosomal ribonucleic acid (rRNA) sequencing. In 17 cases mycobacterial lesions were present only in the joints and skeleton, highlighting the importance of not ruling out mycobacterial infection on the basis of absence of cutaneous or visceral lesions.

An Argentinian Dogo which suffered from anorexia, lymphadenopathy, cachexia and paresis of the hind limbs was diagnosed with trypanosomiasis in Argentina in 2013. In this study, we describe the clinical profile and its evolution as well as the molecular method employed to identify and quantify Trypanosoma evansi.
