Rickettsia africae and Candidatus Rickettsia barbariae in ticks in Israel.

DNA of several spotted fever group rickettsiae was found in ticks in Israel. The findings include evidence for the existence of Rickettsia africae and Candidatus Rickettsia barbariae in ticks in Israel. The DNA of R.

Spotted fever group rickettsiae in ticks collected from wild animals in Israel.

We report molecular evidence for the presence of spotted fever group rickettsiae (SFGR) in ticks collected from roe deer, addax, red foxes, and wild boars in Israel. Rickettsia aeschlimannii was detected in Hyalomma marginatum and Hyalomma detritum while Rickettsia massiliae was present in Rhipicephalus turanicus ticks. Furthermore, a novel uncultured SFGR was detected in Haemaphysalis adleri and Haemaphysalis parva ticks from golden jackals.

Immunological arousal during acute Q fever infection.

Physicians often encounter patients who present with a vague clinical syndrome. A wide serological workup is often ordered, which may include tests for Coxiella burnetii in endemic areas. Often, the results of these tests pose new dilemma, with overlapping positive laboratory assays.

A large Q fever outbreak in an urban school in central Israel.

BACKGROUND. On 28 June 2005, numerous cases of febrile illness were reported among 322 students and employees of a boarding high school located in an urban area in central Israel. Subsequent investigation identified a large outbreak of Q fever which started 2 weeks earlier.

Establishment of cell-based reporter system for diagnosis of poxvirus infection.

Poxvirus detection assays are based on morphology, viral antigens and specific nucleic acids, none of which indicates virus viability or infectious capacity. Determination of virus viability is achieved by propagation in cell cultures and subsequent analysis by the mentioned methods, a process that takes days. Thus, presented here the development of a new assay, named PILA (Poxvirus Infection Luciferase Assay), for rapid detection of infectious poxviruses which is a cell-based reporter assay.
