I report a case of tick-borne ehrlichiosis in which the primary presentation suggested an infectious diarrhea, with impressive leukopenia and thrombocytopenia. Ehrlichiosis must be included in the differential diagnosis of febrile diarrhea in endemic areas because delay in therapy allows
The seroprevalence and seasonal trend of antibody titers against equine monocytic ehrlichiosis (Potomac horse fever) were determined in apparently healthy horses in selected areas of Illinois in 1986. Sera from 1,367 horses (6 months to 29 years old) were evaluated for the presence of antibodies
Infectious diseases that do not primarily affect the gastrointestinal tract can cause severe diarrhea. The pathogenesis of this kind of diarrhea includes cytokine action, intestinal inflammation, sequestration of red blood cells, apoptosis and increased permeability of endothelial cells in the gut
Fifty-five horses were inoculated IV and/or SC with materials containing Ehrlichia risticii, ie, infected whole blood, buffy coat cells, or cell culture, to study clinical and hematologic features of equine monocytic ehrlichiosis (Potomac horse fever). Major clinical and hematologic features of
BACKGROUND
Ehrlichiosis has emerged as an increasingly recognized tick-borne rickettsial disease. It can affect multiple organs including the gastrointestinal tract and liver. Signs and symptoms include abdominal pain, nausea, vomiting, diarrhea, jaundice, and hepatosplenomegaly. Patients commonly
Eight adult cats were inoculated IV (n = 6) or SC (n = 2) with Ehrlichia risticii-infected P388D1 (continuous murine macrophage) cells or with E risticii released from P388D1 cells. Three additional cats were inoculated with organism-free P388D1 cultured monocytes, and 1 cat, which served as a
This case report describes two dogs with granulocytic ehrlichiosis. Dog 1 was a male Labrador retriever with clinical signs of lymphosarcoma. Dog 2 was a female Airedale terrier, whose clinical signs included apathy, pyrexia, diarrhea, and abdominal pain. Examination of blood smears revealed
Adult dogs 1 to 5 were inoculated IV and/or SC with 3, 5, or 6 ml of a suspension containing 1.2 x 10(4) Ehrlichia risticii-infected cells (derived from primary canine monocyte cell cultures)/ml. Dogs 6 to 8 were inoculated IV and/or SC with 3 or 6 ml of 1.2 x 10(5) organism-free cultured canine
Ehrlichia canis infection causes multisystemic disease in dogs (canine monocytic ehrlichiosis, CME) which is associated with variable morbidity and mortality. Atypical clinical manifestations, including gastrointestinal signs, may occasionally occur in CME and approximately 10-15% of dogs are
We report on the clinical, epidemiologic, and laboratory characteristics of the first case of human ehrlichiosis acquired outside the United States caused by an Ehrlichia sp. other than E. sennetsu. The patient, a 24-year-old woman, presumably acquired the infection in Mali in northern Africa; the
A disease named locally as churrío or churrido equino (i.e., equine scours) has occurred for at least 100 years in Uruguay and southern Brazil in farms along both shores of the Merín lake. This report describes cases of churrido equino and provides serologic, pathologic, and DNA-based evidence
BACKGROUND
Much of what is known about human monocytic ehrlichiosis (HME) is based upon studies with adult patients.
OBJECTIVE
To review our experience with HME to better understand the epidemiology, clinical manifestations, and outcome of this disease in children.
METHODS
Demographic, clinical, and
Medical records of 3 dogs from North Carolina and 3 dogs from Virginia with ehrlichial morulae in circulating neutrophils were studied retrospectively. Two clinically distinct disease syndromes, including chronic, moderate to severe anemia (n = 3) and polyarthritis (n = 2) were associated with
Antibody titer to Ehrlichia risticii was determined, in 2,549 equine serum samples, using an indirect fluorescent antibody assay. During 1986, samples were obtained from the Minnesota State-Federal Equine Infectious Anemia Diagnostic Laboratory, the Minnesota Racing Laboratory, from horses admitted
Between the dates of May 4th-August 6th 2002, 46 cases were detected with abdominal pain nausea, vomiting, arthralgia/myalgia, headache, fever, diarrhea and rash, in the middle Blacksea and north inner Anatolia regions. Their laboratory findings yielded elevated levels of liver enzymes (AST, ALT,
