Examined was material taken from five sheep (ewes) and two weaned lambs having naturally contracted Qu rickettsiosis. Described are the clinical symptoms of the disease and the morphologic changes. The diseased animals showed rise in temperature (39.5--40.5 degrees C), loss of appetite, and depression. Some of the weaned lambs manifested slight cough and digestive troubles. Part of the animals showed nervous symptoms--tic movements of the head and limbs. Morphologically, the liver was edematired, of lower compactness, and the spleen was enlarged, the meninges being hyperemic and peppered with pinpointed hemorrhages. Histologically, a strong diffuse activation and proliferation of the liver capillary endothelium was established along with necrobiosis of the liver epithelial cells and a diffuse leukocyte infiltration. Established was also hyperplasia of the reticular cells and the lymph follicles of the spleen and the bronchial lymph nodes. The epithelial cells of the kidney tubules were involved in vacuolar dystrophy, and in the medular section there were fibroblastic proliferations with hyperemia. Inflammatory changes in the brain were also found.

Scrub typhus is one kind of rickettsial disease and may cause fever, cough, and skin rashes in infected humans. Regarding liver involvement, it was uncommon to be reported in previous medical literature from Western countries. This study observes the relationship between scrub typhus and liver function. From January 1998 to August 2003 in Kaohsiung Chang Gung Memorial Hospital in Taiwan, we observed 30 patients with scrub typhus, and 29 of them had liver function abnormality. In these patients, we found 89.3% with elevated aspartate aminotransferase (AST) levels, 91.7% with elevated alanine aminotransferase (ALT) levels, 84.2% with elevated alkaline phosphatase (ALP) levels, and 38.5% with elevated total bilirubin levels. In our study, there is a close relationship between scrub typhus and impaired liver function tests. Therefore, if patients are found with fever of unknown origin and abnormal liver function, we should take scrub typhus into consideration.

Australia has 4 rickettsial diseases: murine typhus, Queensland tick typhus, Flinders Island spotted fever, and scrub typhus. We describe 7 cases of a rickettsiosis with an acute onset and symptoms of fever (100%), headache (71%), arthralgia (43%), myalgia (43%), cough (43%), maculopapular/petechial rash (43%), nausea (29%), pharyngitis (29%), lymphadenopathy (29%), and eschar (29%). Cases were most prevalent in autumn and from eastern Australia, including Queensland, Tasmania, and South Australia. One patient had a history of tick bite (Haemaphysalis novaeguineae). An isolate shared 99.2%, 99.8%, 99.8%, 99.9%, and 100% homology with the 17 kDa, ompA, gltA, 16S rRNA, and Sca4 genes, respectively, of Rickettsia honei. This Australian rickettsiosis has similar symptoms to Flinders Island spotted fever, and the strain is genetically related to R. honei. It has been designated the "marmionii" strain of R. honei, in honor of Australian physician and scientist Barrie Marmion.

Tsutsugamushi disease is an acute infectious rickettsial disease caused by the intracellular parasite Orientia tsutsugamushi. Due to its variety of clinical signs, this disease is often misdiagnosed. This article examines a total of 4 patients who visited our clinics with fever and sore throat. 3 of them had body temperature of 39.5 Celsius degrees when admitted. The characteristic black eschar occurred on 4 of them. Lymphadenopathy occurred on 2 of them. Cough occurred on 1 of them. Lab tests showed that 3 of them had Leukocytosis, 1 of them had increased bronchovascular markings, and 3 of them had Weil-Felix test positive. After admission, all patients, who were confirmed of diagnosis of tsutsugamushi disease instead of tonsillitis, received the comprehensive treatment and cured afterwards.

AbstractRickettsial infections are an underrecognized cause of febrile illness in sub-Saharan Africa. To evaluate the epidemiology and clinical features of rickettsial disease in pediatric patients in Ghana, we screened blood samples from febrile children aged less than 15 years presenting to an outpatient department in Ghana's Ashanti Region for the presence of rickettsial DNA. We detected Rickettsia felis in 7/470 (1.5%) blood samples, using two independent real-time polymerase chain reactions. No other Rickettsia species were found. R. felis was detected repeatedly in one patient, and coinfection with Plasmodium falciparum was found in 3/7 samples. Symptoms apart from fever included cough (6/7) and vomiting (4/7). None of the R. felis-positive patients reported a rash. This study is the first report on R. felis in Ghana and adds to the growing evidence for its widespread occurrence with and without malaria coinfection in sub-Saharan Africa.
