Serological and morphological comparison of Theileria orientalis stocks from Australia, Britain, Iran, Japan and the USA with a more pathogenic stock from Korea, corresponding to T sergenti of Russian literature, showed that they all belong to one species, for which the name T orientalis is recommended. T orientalis is now known to occur on all continents. Macroschizonts and microschizonts, found in some of the calves infected with the Korean stock, are described and illustrated. Infections with the Korean stock were associated with early hyperthermia during the period schizonts are found, and commonly with high parasitaemias and anaemia even in unsplenectomised calves. The higher pathogenicity of this stock may be related to a faster rate of division. T orientalis may cause latent infection in sheep. With the exception of the stock from the USA, all stocks could be transstadially transmitted by Haemaphysalis longicornis and, or, H punctata.

Oral infection with Salmonella ochiogu resulted in the manifestation of clinical salmonellosis in laboratory rabbits. Infection was associated with septicaemia, anaemia and terminal pneumonia. Organisms were excreted in the faeces on the first day post-inoculation, and cultures of most visceral organs revealed widespread dissemination. This serotype appears to be highly pathogenic for rabbits.

Malaysia's maternal mortality rate has been showing a steady decline and in 1966 was 1.7/1000 in contrast to the 6.7/1000 rate in 1948. Yet, considerable variations exist within the country, from as low as 0.31/1000 in the large towns to as high as 5.58/1000 in rural areas. The 554 maternal deaths in 1966 show a marked disparity in racial distribution. Malays who form 50.2% of the total population form 85.5% of total deaths. The possible reasons for this, apart from poverty and malnutrition, are ignorance, fear and prejudice in availing themselves of public health services and reliance on bomohs and handiwomen and fatalism. The other ethnic groups, the Chinese and Indians, make full use of whatever health service is available in their locality. The main obstetric causes for maternal deaths were hemorrhages, neglected labors, and toxemia. Infection was responsible for only 7.5% of the deaths. Among associated diseases, anemia was the predominant cause. Analysis of social factors reveals a high percentage of avoidable factors: 24.2% due to patient errors and 27% due to lack of or inexpert care during antenatal care, and 19% inadequate care in the hospital. In view of the high maternal mortality and fetal loss prevalent particularly in problem districts of Malay, a study of maternal and child health services in the country was undertaken. As a result of this investigation, priority has been given to the idea of bringing the health services to the rural population. In 1968 7.1% of the national budget is being spent on public health services. It is envisaged that for every 50,000 of rural population a Health Unit, consisting of a main Health Center with 4 subcenters and 20 resident midwife cum clinics at the periphery, should be built to serve about 2000 of the population. Thus far 39 main centers, 45 subcenters, and 751 midwife cum clinics have been built and staffed, thus providing obstetric and health services for over 2,000,000 rural population. Other measures that have been taken are outlined. In addition the government has initiated a general rural reconstruction and development projects in an effort to improve the country's social and economic conditions. Particular focus has been on the rural areas.

Twenty-five patients with severe renal impairment treated by periodical haemodialysis underwent splenectomy (for spleen injury or tuberculosis in 2). All have been on long-term follow-up. At present, 7 patients have not improved; 7 are no longer transfused but remain anaemic with a less than 20% haematocrit; 11 have a more than 20% haematocrit without transfusion. Statistical analysis of the data shows that splenectomy, when effective, acts by reducing excess plasma volume and excessive haemolysis. Red cell production is not increased. The beneficial effect of splenectomy cannot be predicted from age, sex, cause of renal impairment or severity of anaemia. However, in this series there was a positive correlation between the degree of haemolysis, the site of red cell sequestration, the size of the spleen and the effectiveness of splenectomy. Infection, notably septicaemia in grafted (and immunodepressed) patients is a major risk of splenectomy and requires preventive measures.

Infection of 10-day-old chicken embryos with an avian retrovirus. Rous-associated virus type 7, resulted in a disease characterized by stunting and hyperlipidemia. By 20 days after hatch, infected chickens were smaller than hatchmates and developed ataxia and obesity over the next 30 days. Histological examinations of livers from infected chickens revealed a diffuse panlobular fatty infiltrate involving an accumulation of fat in microdroplets. Electron microscopic examinations of livers from infected chickens revealed hepatocytes with swollen mitochondria that lacked cristae. The thyroid and pancreas were infiltrated with lymphoblastoid cells by 1 week after hatch. An examination of the blood revealed a mild anemia, a frank lipemia, and high levels of uric acid. This syndrome induced by Rous-associated virus type 7 in chickens may be useful for elucidating the nature of several diseases, including that found in the fatty liver and kidney syndrome of chickens and that observed in a strain of obese chickens.

The GM-CFC assay for granulocyte-macrophage progenitors and the BFU-E and CFU-E assay for early and late erythroid progenitors from cat bone marrow were characterized. GM-CFC gave 59 +/- 4 to 118 +/- 6 colonies per 10(5) bone marrow cells using colony stimulating factors (CSF) from cat, mouse or human sources. The CFU-E and BFU-E assays gave 114 +/- 7 and 58 +/- 7 colonies respectively with optimum doses of erythropoietin. Irradiated cat bone marrow cells were good sources of CSF and of burst promoting activity for these assays. Kittens infected with feline leukaemia virus, subgroup C (FeLV-C), which induces pure red cell hypoplasia, showed the incidence of BFU-E decreased to 25-35% of controls as early as one week postinfection, and even lower values at later times. In contrast, the incidence of GM-CFC remained normal for several weeks. No evidence of inhibitory cells or of lack of stimulatory cells in the infected marrows was seen when they were cultured together with normal marrow in the BFU-E assay. Conversely, normal marrow cells were not able to restore BFU-E growth from infected marrow. This suggests a direct action of FeLV-C on early erythroid precursors. Infection with FeLV, subgroup A, which induces only a mild transitory anaemia, produces only a moderate decrease in the incidence of BFU-E.

Three hundred and fifty-seven serum samples from pregnant African women were examined for Toxoplasma gondii antibodies with indirect haemagglutination test in Dar es Salaam. Out of these 222 women were normal, sixty-nine had anaemia and sixty-six were suffering from hypertension. Infection rate in normal pregnant women was 41.9%, in anaemic women 52.5%, and in those suffering from hypertension 66.7%. Highly significant relationship was observed between Toxoplasma infection and anaemia, and hypertension. Infection rate was significantly high in women who had histories of abortion. The results suggested associations of Toxoplasma gondii infection with hypertension and anaemia in African women.

Infection of an intracardiac prosthesis, the incidence of which is about 2.5% among patients having undergone valve replacement, is a serious complication with considerable morbidity and mortality. Early prosthetic valve endocarditis (PVE), with an onset within 60 days of valve replacement, accounts for approximately one-third of all cases, while the remaining two-thirds, occur more than two months postoperatively (late prosthetic valve endocarditis). Prosthetic valve endocarditis is most commonly caused by Staphylococcus epidermidis, less frequently by viridans streptococci, Staphylococcus aureus, and gram-negative bacilli. The most likely pathogenetic mechanisms in prosthetic valve endocarditis are intraoperative contamination and postoperative infections at extracardiac sites. Prominent clinical features include fever, new or changing heart murmurs, leukocytosis, anemia and hematuria. The etiologic microorganism can be isolated in more than 90% of all cases. Patients with proven prosthetic valve endocarditis should be examined daily to detect signs of congestive heart failure and changes in murmurs; electrocardiographic monitoring is essential for documentation of arrhythmias. With limitations, echocardiography, especially two-dimensional, may help to demonstrate vegetations or valvular dehiscence. Cinefluoroscopy may reveal loosening or dehiscence of the sewing ring or impaired motion of a radio-opaque poppet due to thrombus or vegetation. Cardiac catheterization, not always necessary even when surgical intervention is anticipated, may provide valuable information on the degree of dysfunction, multiple valve involvement, left ventricular function and extent of concomitant coronary artery disease. In patients with mechanical valves, prosthetic valve endocarditis may be associated with a high incidence of valve ring and myocardial abscesses; the reported frequency of valve ring abscesses is lower with porcine heterografts. Infections on mechanical valves characteristically localize to the sewing ring with subsequent detachment of the prosthesis and valvular incompetence; infections on porcine heterografts tend to localize to the cusps, leading to valvular incompetence because of leaflet destruction. Large vegetations may result in functional stenosis. Over the last ten years the overall mortality of prosthetic valve endocarditis was 53.8%; 73.6% in early and 43% in late prosthetic valve endocarditis. More recently, however, the survival rate appears to be improving. In general, the mortality associated with prosthetic valve endocarditis caused by fungi and Staphylococcus aureus is highest and that of streptococci lowest.(ABSTRACT TRUNCATED AT 400 WORDS)

Patients with HCL are subject to a variety of medical problems. Many of these complications are caused by the cytopenias and splenomegaly produced by proliferating neoplastic cells. Infection is a common cause of morbidity in HCL, but it is not clear whether there is an inherent defect in the immune system. The incidence of infection is related to neutropenia and is increased by the administration of cytotoxic drugs and corticosteroids; such drugs should be used cautiously in these patients. Opportunistic or unusual pathogens occur frequently in HCL, but recovery from such infections is the rule if the diagnosis is made early. Marrow hypoplasia is not infrequently seen and may present diagnostic difficulties. Such patients may have a lower tumor burden and clinically milder anemia. Hemorrhagic complications are unusual in HCL, though many patients have platelet function abnormalities. Other medical problems occur with increased frequency in HCL, and failure to recognize them leads to increased morbidity in this disease. Autoimmune disease is seen in up to one fourth of patients. It takes the form of self-limited skin and joint disease, or a more progressive, systemic of patients. It takes the form of self-limited skin and joint disease, or a more progressive, systemic vasculitis. Both forms can usually be treated with splenectomy or corticosteroids, but alkylating agents can also be used successfully. Bone disease is usually localized and responds well to radiotherapy. Other problems such as amyloidosis, multiple myeloma, and paraproteinemia are uncommon in HCL.

Presently available data continue to support the idea that once a horse is infected with equine infectious anemia virus it remains infected indefinitely. Infection may not always be demonstrated by inoculation of plasma, serum, or whole blood transfusions into susceptible recipients, but transfusions of fresh whole blood will be infective in at least 95% of the horses testing positive in the agar gel immunodiffusion test. For detection of infectivity in a small percentage of inapparent carriers, it appears necessary to inoculate washed leukocytes collected over a period of time.
