BACKGROUND Severe fever with thrombocytopenia syndrome (SFTS) is an emerging disease that is caused by a novel bunyavirus, referred to as SFTS virus. During January 2011 to December 2011 we conducted a case-control study in Henan, Hubei and Shandong Provinces of China to determine the risk factors for SFTS. METHODS Case-patients were identified in hospitals and reported to provincial Centers ...
52: Lone Star Tick Bites Big Apple: Ehrlichia chaffeensis-Induced Hemophagocytic Lymphohistiocytosis
Alkhurma virus is a flavivirus, discovered in 1994 in a person who died of hemorrhagic fever after slaughtering a sheep from the city of Alkhurma, Saudi Arabia. Since then, several cases of Alkhurma hemorrhagic fever (ALKHF), with fatality rates up to 25%, have been documented. From January 1, 2006, through April 1, 2009, active disease surveillance and serologic testing of household contacts i...
suspected. However, F. philomiragia DNA was found in 19% of a sample of dog ticks (Dermacentor reticulatus) in France (9). This finding suggests that D. reticulatus, which is now broadly distributed across Europe because of global warming and increased travel with pets, may have a role in the life cycle and transmission of F. philomiragia (10). The patient did not own a dog and did not recall h...
OVERVIEW Q fever is a zoonotic disease caused by Coxiella burnetii. Farm animals and pets are the main reservoirs of infection. INFECTION Cats become infected by ingestion or inhalation of organisms from contaminated carcases of farm animals, or tick bites. Infection is common, as shown by several serological studies. CLINICAL SIGNS Experimentally, fever, anorexia and lethargy have been not...
Specimens of the hard tick Amblyomma triste were found infected with Rickettsia parkeri in an area of Argentina (General Lavalle, Buenos Aires Province) where cases of human illness attributed to this microorganism have been reported. Molecular detection of R. parkeri was based on polymerase chain reactions that amplify a ca. 400-bp fragment of the 23S-5S intergenic spacer and a ca. 500-bp frag...
Human granulocytic ehrlichiosis (HGE) was recently described in North America. It is caused by an Ehrlichia species closely related to Ehrlichia phagocytophila and Ehrlichia equi, recognized to infect mostly ruminants and horses, respectively. The vector in North America is the tick Ixodes scapularis, which is also the vector of the Lyme disease agent, Borrelia burgdorferi. Previous serologic s...
