Twenty five cattle were infected with T. vivax, 25 with T. congolense, and 25 served as controls. Pathogenic clinical signs of trypanosomal infection were not observed. Secondary bacterial infections were common. Fever, increased heart and respiratory rates, anorexia, and emaciation developed. Elevations in parasitemai and body temperature were positively correlated in the T. vivax group. Infected groups were affected non-uniformly, with some animals in each group remaining asymptomatic and tending to have lower parasitemias. The T. vivax parasitemia was cyclic and the organisms had a genaration time of 7.9 SD 2.5 hours. The first peak of parasitemia in both infections was closely associated with the development of pancytopenia, i.e. anemia, leukopenia, and thrombocytopenia. The bone marrow erythroid response in the T. congolense group was significantly greater thn that in either the T. vivax or control groups. Leukopenia was due to concomitant neutropenia and lymphopenia.

Experimental Rocky Mountain spotted fever was studied in guinea pigs following intraperitoneal inoculation of 10(7) Rickettsia rickettsii. After a 2-day incubation period, animals developed fever, progressive emaciation, and scrotal swelling with necrosis. Vasculitis, with increased small vessel permeability for colloidal carbon, was evident in cremaster muscles as early as 1 day after inoculation. Inflammatory changes in vessels became progressively more severe as numbers of circulating rickettsiae increased. Thrombosis and vascular occlusion were first evident on day 4. Mild thrombocytopenia developed, coinciding with the development of vasculitis, and preceding the appearance of either fibrin-split products in blood or thrombi in vessels. Rickettsiae were first detected in blood on day 2; peak rickettsemia occurred on days 5 to 8. Rickettsiae were demonstrated in inflamed vessels on day 5 and later, but not at earlier stages. Serum lysozyme concentration was moderately elevated and hemolytic complement was moderately depressed throughout the illness. Agglutinating antibody was present in low titers on days 3 to 10. Antibody titers increased on days 12 to 16 after the rickettsiae were cleared from blood. These studies indicate that vasculitis seen early in the course of Rocky Mountain spotted fever is the result of rickettsial infection, but is not dependent on the presence of rickettsiae in endothelial cells or other blood vessel components.

The acquired immunodeficiency syndrome (AIDS) was first diagnosed in burundi in 1983 when a large number of patients were registered with Kaposi's sarcoma, cryptococcal meningitis, and disseminated candidiasis. In the 1st phase of the disease the vi rus is dormant. In the 2nd phase seroconversion appears; and in the 3rd phase generalized adenopathy emerges. In the 4th phase the full-blown disease appears as a result of cellular immunity deficit with emaciation, fever, sweating, chronic diarrhea, asthenia, blood parameter changes (lymphopenia, thrombocytopenia, leukopenia, anemia, and specific immune disorders). The early phases can be diagnosed by serological tests. During 1989 a group of 155 patients with 1st signs of seropositivity were studied in the central hospital of Bugumbura. The available clinical diagnostic markers were: 56 cases of herpes, 26 cases of generalized adenopathy, 25 cases of inflammatory infiltration of paraganglionic zones, 13 abscesses and phlegmons, 8 cases of chronic proctitis, 8 prurigo cases, 7 cases of chronic pneumonia and bronchitis, 4 cases of paresis of the facial nerve, 4 cases of Kaposi's sarcoma, 2 cases of fresh syphilis, 2 cases of anemia, asthenia, dizziness, and weight loss. Tomo- and zonographical X-ray study of the thorax of 80 patients aged 20-65 (51 men and 29 women) was performed. In 62 patients changes in the lungs were evident. In 2 patients tuberculosis of the lungs was diagnosed: miliary TB in a 26-year woman and disseminated TB in a 31-year man. 2 chronic and 3 bronchial, and 10 interstitial pneumonia cases were diagnosed in 15 patients with average age of 30 years. 4 patients had peribronchial and pneumonic infiltrations. In a group of 45 patients magnified picture showed no deformation in the lungs; and only 5 had respiratory organ pathology. Interstitial pneumonia was the most often diagnosed ailment by X-ray inpatients infected with HIV.

A retrospective was designed to analyse the mode of presentation, clinical signs and haematological and biochemical abnormalities in 225 consecutive Black (Zulu) patients who were admitted to a general medical ward between the years 1970 and 1981 and in whom cirrhosis was later diagnosed. The most common presenting complaint was swelling of the body (60% of the patients), followed by abdominal pain (32%) and episodes of bleeding, mainly from the gastrointestinal tract (19%). On examination, hepatomegaly was encountered in 66% of the patients, with moderate to massive enlargement in 40%. Ascites was detected in 56%, with tense abdominal distension in 34%. Jaundice was present in 38% and emaciation, mental disturbance and splenomegaly in over 25%. Spider naevi (found in 2 patients) and Dupuytren's contracture (found in 1) were very rare. Thrombocytopenia and a high ESR were common. Over 90% of patients had low albumin and high globulin concentrations (albumin less than 20 g/dl and globulin greater than 60 g/dl in 25%). Bilirubin and alkaline phosphatase levels and the prothrombin index were found to be within normal limits in 32%, 24% and 52% of cases respectively. Histologically the lesion was most commonly micronodular (73%) with variable deposits of fat and iron. Peritoneoscopy was the most useful special investigation in the diagnosis of cirrhosis, leading to a correct diagnosis in 77% of cases. In conclusion, the clinical signs, biochemical abnormalities and histological features suggest that the factors causing cirrhosis in the community studied are mixed; it may result from the combined effects of alcohol abuse, malnutrition and chronic viral (e.g. hepatitis B) infections.

A rare case of chest-wall angiosarcoma with high tendency of local recurrence and with a solitary gastric metastasis is reported. The patient was an 84-year-old man who had a left lateral thoracic mass with a colic pain. The histological diagnosis of a biopsied specimen suggested an angiosarcoma. The first resection was performed, the resected specimen consisted of the 8th, 9th and 10th ribs including the tumor. However the tumor recurred around the primary site and the second resection was undertaken eight months after the first resection. Only three months after the second resection a second chest-wall recurrence together with a solitary gastric metastasis was found. Progressive emaciation, anemia and thrombocytopenia became evident, and the patient died the 40th day after the gastrectomy. Primarily a wide resection of the chest wall beyond the pathologically negative region around the tumor is thought to be necessary.

Three specific pathogen-free cats experimentally infected with feline immunodeficiency virus (FIV) strains Petaluma, TM1 and TM2, respectively were observed for over 8 years. Without showing any significant clinical signs of immunodeficiency syndrome (AIDS) for 8 years and 4 months of asymptomatic phase, the Petaluma-infected cat exhibited severe stomatitis/gingivitis, anorexia, emaciation, hematological and immunological disorders such as severe anemia, lymphopenia, thrombocytopenia, and decrease of CD4/CD8 ratio to 0.075, and finally died with hemoperitoneum at 8 years and 8 months post-infection. Histopathological studies revealed that the cat had systemic lymphoid atrophy and bone marrow disorders indicating acute myelocytic leukemia (aleukemic type). Plasma viral titer of the cat at AIDS phase was considerably high and anti-FIV antibody titer was slightly low as compared with the other FIV-infected cats. In addition, immunoblotting analysis using serially collected serum/plasma samples of these cats revealed that antibodies against FIV proteins were induced in all the infected cats, however in the Petaluma-infected cat anti-Gag antibodies disappeared during the asymptomatic period. These results suggested that plasma viral load and anti-FIV Gag antibody response correlated with disease progression, and supported FIV-infected cats as a suitable animal model of human AIDS.

A five-year-old female dog was presented with a four-week history of inappetence, weight loss, and skin and gait abnormalities. Physical examination revealed weakness, depression, incoordination of the posterior limbs, emaciation, skin and hair coat alterations, peripheral lymphadenopathy, pale mucous membranes and fever. Laboratory analysis of samples revealed abnormalities which included anaemia, neutrophilic leucocytosis, thrombocytopenia, low serum glucose and albumin concentrations, and increased serum alkaline phosphatase activity. The diagnosis was confirmed microscopically, by demonstrating the presence of Hepatozoon canis gametocytes within neutrophils in Giemsa-stained peripheral blood smears. Treatment consisting of toltrazuril and a trimethoprim-sulfamethoxazole combination was effective in relieving the clinical signs and clearing the blood of H. canis gametocytes. To the authors' knowledge, this is the first detailed clinical description of H. canis infection in a dog in Turkey.

A 48-year-old man was referred to our hospital in December, 2005 because of general fatigue, gait disturbance and bradycardia. He had a history of polysurgery due to recurrent ileus and had been treated with home total parenteral nutrition for the short-bowel syndrome since 2003. Clinical findings on admission included marked emaciation and severe weakness of the extremities. Pancytopenia was noted in the peripheral blood. The serum levels of copper and ceruloplasmin were 3 microg/dl and 3 mg/dl, respectively, while Vit. B12 and folate were within the normal range. The bone marrow demonstrated cytoplasmic vacuolation in the myeloid and megakaryocytic series, and sideroblastic changes. No evidence of hematologic malignancies was presented. The diagnosis was copper deficiency and the patient was treated with copper supplementation. Four weeks after copper therapy, the serum level of copper rose to 50 microg/dl and ceruloplasmin to 14 mg/dl. Significant improvements in the hematologic profile, ECG findings and weakness of extremities were noted. Although bicytopenia (anemia and neutropenia) is considered to be a feature of hematologic disorders caused by copper deficiency, the present case showed pancytopenia. The exact mechanism of the unusual association of thrombocytopenia and other abnormalities with copper deficiency remains to be elucidated.

Gammaretroviral vectors are an efficient means to effect gene therapy. However, genotoxicity from insertion at nonrandom sites can confer a competitive advantage to transduced cells, resulting in clonal proliferation or neoplasia. Six pig-tailed macaques (Macaca nemestrina) underwent total body irradiation and reconstitution with autologous stem cells genetically modified by a gammaretroviral vector overexpressing HOXB4. Two animals were euthanized owing to irradiation- or transplantation-associated toxicity, whereas the other 4 had successful reconstitution. Of the 4 macaques with successful reconstitution, 1 has no long-term follow-up information; 1 was euthanized owing to infection with simian varicella virus infection 18 months post-total body irradiation; and the 2 others are described herein as case Nos. 1 and 2. After being stable for 3 years, case No. 1 developed pancytopenia and petechiation, and after 2 years of stability case No. 2 developed anemia and thrombocytopenia. Despite therapy, the animals deteriorated and were euthanized. Gross findings included emaciation; case No. 1 also had hemorrhage, peritonitis, and cholecystitis. Histologically, bone marrow was hypercellular with predominately blast cells of all hematopoietic lineages, though with myeloid predominance, and with maturation arrest and blast cell dysplasia (myelodysplasia). Myelodysplasia was likely from a combination of insertional mutagenesis by the retroviral vector and overexpression of HOXB4. Consequences of myelodysplasia included the blood dyscrasias and, in case No. 1, hemorrhage, bacterial cholecystitis, hepatitis, and peritonitis.

The authors carried out microscopic examination of blood smears of 1438 dogs infected with Leishmania infantum. Unusual findings of leishmaniosis associated with circulating parasitised cells are described in four dogs. Most of the dogs presented severe illness, with lethargy, dysorexia, emaciation and alterations of the haematological pattern (anaemia, thrombocytopenia, neutrophilia and monocytosis). In three cases, leishmaniosis was associated with ehrlichiosis. On examination of peripheral blood smears, Leishmania sp. amastigotes were observed both in various circulating leukocytes (neutrophil, monocyte, macrophage) and free. In conclusion, parasites can rarely be detected in blood smears (in 0.28% of the animals examined); thus, the time-consuming microscopic search for amastigotes can make only a weak contribution to the conventional diagnosis of canine leishmaniosis.
