Neonatal haemolytic disease was diagnosed in a Bos indicus cross bred beef herd in south-east Queensland. The evidence suggested that this was due to B. argentina vaccination for babesiosis while non-pregnant or less than one month pregnant. The cows received 5 or 6 vaccinations during their breeding life, which indicated that antibody levels can persist for long periods. The autopsy, histopathological and haematological findings indicated that the mechanism was disseminated intra-vascular coagulation which occurred in calves dying within 24 hours of birth. This resulted in fibrin deposition in pulmonary capillaries and severe pulmonary oedema.

A case of babesiosis in an asplenic individual is reported. A course characterized by fever, haemolysis, hepatitis, depressed mental status and non-cardiac pulmonary oedema was observed. Studies performed on the patient's lymphocytes revealed profound depression in mitogenic responses during her acute disease which returned to normal with recovery. Serum factor(s) were implicated in causing these changes. Review of the literature on babesiosis in asplenic hosts revealed European patients with disease caused by bovine species of Babesia are at significantly higher risk of a fatal outcome than North Americans with disease caused by murine species.

Babesiosis is a tick-borne protozoal disease with infrequent clinical complications. We report three cases of noncardiogenic pulmonary edema in patients from Nantucket Island, MA, with a history of Lyme disease and review the clinical presentation of babesiosis and its treatment. Respiratory complications in our patients, as well as in the four previously reported cases in the literature, occurred a few days after initiation of medical therapy. We hypothesize that the pathophysiology of the pulmonary edema is multifactorial, due to decreased deformability of the infected erythrocytes, increased cytoadherence of red blood cells in capillaries and venules, and a possible role of excessive production of certain cytokines, such as tumor necrosis factor and interleukin-1.

Specific treatment of canine babesiosis consists of antibabesial drugs and, in severely anaemic animals, blood transfusion. Supportive therapy is also required, particularly in animals with complicated disease. Strategies for treatment of uncomplicated and complicated babesiosis are discussed. Definitive recommendations cannot be provided on the basis of available information, but suggestions are made, based on accepted therapeutic principles, pathophysiological mechanisms, therapy used in human malaria, and clinical experience. The problems of fluid therapy in complicated babesiosis, particularly in animals with oliguria, cerebral babesiosis and pulmonary oedema, are presented, with consideration given to the use of hypertonic fluids. The benefits of bicarbonate and alternative alkalinisers in life-threatening lactic acidaemia, a relatively common occurrence in complicated babesiosis, are debated, as are the benefits of oxygen therapy in anaemic hypoxia. Drug therapy and management of specific babesial complications are discussed. The rationale for supportive drugs commonly used in uncomplicated babesiosis, including lipotropic agents, haematinics and glucocorticoids, is examined. This review is designed to propose therapeutic guidelines and to stimulate interest in problematic aspects of supportive therapy for canine babesiosis.

Rhabdomyolysis was diagnosed in two dogs with babesiosis. The first animal presented with muscle pain and caramel-coloured urine, and had markedly elevated serum myoglobin and muscle enzymes. Acute renal failure complicated the clinical picture. The second dog exhibited muscle pain and tremors, together with neurological signs and pulmonary oedema, and died soon after admission. Muscle necrosis and haemorrhage were found at necropsy. In human malaria, a disease clinically similar to canine babesiosis, rhabdomyolysis is unusual, but clinically silent muscle damage appears to be common. Likewise, biochemical evidence of muscle damage is readily found in experimental bovine babesiosis. Muscle enzymes were mildly elevated in three dogs with severe babesiosis and pigmenturia but there was no obvious muscle damage, indicating that this might also apply to canine babesiosis. The pathogenesis of infection-associated rhabdomyolysis and acute renal failure remains unclear, but inflammatory cytokines and nitric oxide could play an important role.

South Africa appears to be the only country where feline babesiosis is a significant clinical entity in domestic cats. Little is known about its epidemiology or the clinical challenges facing practitioners. A questionnaire posted to 1760 South African veterinarians was returned by 16%, representing approximately 40% of practices. Just over half reported seeing feline babesiosis, with most cases occurring in the coastal areas of the Western Cape, Eastern Cape and KwaZulu-Natal Provinces. Overall incidence is highest in summer, but seasonality is less pronounced in non-seasonal and winter rainfall areas. No age, breed or sex predisposition was identified. Weight loss, weakness, anaemia, fever and icterus are common clinical findings. Complications include hepatopathy, renal failure, pulmonary oedema, cerebral signs, immune-mediated haemolytic anaemia and concurrent infections. The antibabesial drug of choice is primaquine phosphate. Response to therapy is generally good, but recurrence and chronic infections were identified as problems. The average mortality rate was 15%. Approximately 3000 cases are seen annually by the respondents, at an estimated cost of R750 000 to the owners. Feline babesiosis is a significant problem in South Africa, and further investigations of taxonomic status, concurrent infections, chemotherapy, complications and management of refractory cases are warranted.

Babesia (canis) rossi infection is common in dogs in South Africa, and frequently causes severe, life-threatening disease. Acidemia, persistent hyperlactatemia, hemoconcentration, elevated creatinine, cerebral babesiosis, pulmonary edema and pancreatitis are all associated with mortality rates above 30%, compared with overall mortality of 12% in admitted cases. Although half the admitted cases are severely anemic, hemoconcentration is associated with far higher mortality. Cerebral babesiosis is uncommon, but carries a poor prognosis. The pathological mechanism has been suggested to be endothelial cell damage and necrosis, followed by segmental microvascular necrosis with perivascular edema and hemorrhage. Renal involvement in babesiosis resembles the functional renal failure of sepsis. Hypotension is common, and other cardiovascular disturbances have been documented. Cerebellar ataxia, rhabdomyolysis and pancreatitis are recently identified complications. While the previous categorization into "severe" (life-threatening anemia) and "complicated" (complications not directly attributable to anemia) disease has proved useful, the distinction is artificial and probably unnecessary. An updated approach to classification is suggested, aimed at grouping animals by severity and prognosis, and using simple measures, such as clinical collapse and abnormal breathing, as much as possible. Although inflammatory mechanisms are undoubtedly important in the pathophysiology of babesiosis, there can be little doubt that tissue hypoxia plays a major role in the disease process.

Reported here is a rare case of babesiosis with pulmonary complications followed by a review of the literature. Babesiosis presents clinically as a malaria-like illness with fever, chills, headache, fatigue with lymphopenia, atypical lymphocytes, mildly or transiently elevated serum transaminases, thrombocytopenia, and increased lactate dehydrogenase (LDH) levels. The diagnosis of babesiosis is based on identification of Babesia spp. on a peripheral blood smear. Babesiosis is usually mild in normal hosts, but it may be severe or even fatal in asplenic patients. Pulmonary manifestations are rare in babesiosis, but non-cardiogenic pulmonary edema (NCPE) is the most frequent manifestation. NCPE in babesiosis does not appear to be related to the degree of parasitemia or splenic function and its onset may be early or late. NCPE usually resolves rapidly with supportive treatment; it is rarely fatal. Clinicians should suspect NCPE in patients with babesiosis who acutely develop shortness of breath and have chest radiograph findings compatible with acute pulmonary edema without cardiomegaly or pleural effusions.

Fevers of unknown origin (FUOs) are defined as prolonged fevers of 101 degrees F or greater lasting 3 or more weeks that remain undiagnosed after comprehensive inpatient/outpatient laboratory testing. Tick-borne infections are uncommon causes of FUOs. Any infectious disease accompanied by prolonged fevers can present as an FUO if the diagnosis is not suspected or if specific laboratory testing is not done to confirm the diagnosis. Babesiosis is transmitted by the Ixodes scapularis ticks endemic to areas in the northeastern United States. We present the case of a 73-year-old, non-human immunodeficiency virus, male from Long Island who presented with FUO for 6 weeks. As with malaria, there are usually few or no localizing signs in babesiosis. During the patient's hospitalization, babesiosis was suspected on the basis of nonspecific laboratory findings, that is, relative lymphopenia, thrombocytopenia, thrombocytopenia, and an elevated lactate dehydrogenase. When babesiosis was considered in the differential diagnosis, stained blood smears demonstrated the red blood cell inclusions of babesiosis. In the hospital, the patient developed noncardiac pulmonary edema, which rapidly resolved which has been described as a rare complication of babesiosis. He also had an elevated immunoglobulin-M Lyme titer indicating coinfection with Lyme disease. Although his hemolytic anemia persisted for weeks, he only had 3% parasitemia and intact splenic function. We believe this to be the first case of babesiosis presenting as an FUO in a normal host.
