Cases of Q fever detected in residents of the novosibirsk region hospitalized with suspection of infections transmitted by ticks.

Klin Lab Diagn 2021 Apr;66(4):229-236

Institute of Chemical Biology and Fundamental Medicine SB RAS.

Coxiella burnetii is the causative agent of Q fever (coxiellosis), which, in addition to acute manifestations, often occurs in a latent form, is prone to chronic course and, in the absence of antibiotic therapy, has a high risk of disability or death. As a result of the presence of a wide range of clinical manifestations specific to other infectious diseases, the use of laboratory test methods (LTM) is required to make a diagnosis. The presence of Q fever anthropurgic foci in the Novosibirsk region was described in the 90s of the last century, but due attention to its laboratory diagnostics is not paid in this region.

School of Environment and Natural Resources, Doon University, Dehradun, Uttarakhand, 248 012, India.

In the present scenario, tick-borne diseases (TBDs) are well known for their negative impacts on humans as well as animal health in India. The reason lies in their increased incidences due to global warming, environmental and ecological changes, and availability of suitable habitats. On a global basis, they are now considered a serious threat to human as well as livestock health. Read More

Current tools for the diagnosis and detection of spotted fever group Rickettsia.

Acta Trop 2021 Jun 11;218:105887. Epub 2021 Mar 11.

Tropical Infectious Diseases Research and Education Centre, Level 2, High Impact Research Building, Universiti Malaya, 50603 Kuala Lumpur, Malaysia. Electronic address:

Spotted fever group (SFG) rickettsiae causes a number of diseases in humans worldwide, which can range from mild to highly lethal. Since the clinical presentations of rickettsioses caused by SFG rickettsiae are variable and may be similar to the diseases caused by other rickettsiae, such as Orientia tsutsugamushi (agent for scrub typhus), Coxiella burnetii (agent for Q fever) and the typhus group rickettsiae (agents for epidemic and murine typhus), the accurate diagnosis of infections caused by SFG Rickettsia remains challenging especially in resource-poor settings in developing countries. This review summarizes the various diagnostic and detection tools that are currently available for the confirmation of infections by SFG rickettsiae. Read More

Gastrointestinal and hepatic symptoms of tickborne diseases.

Vnitr Lek 2020 ;66(4):232-235

While investigating patients with gastrointestinal (GI) and/or hepatic symptoms, tickborne diseases are only rarely considered to be the cause. However, the Czech Republic is an endemic region for several of tickborne diseases and, therefore, they should be a part of differential diagnosis of GI symptoms of unknown origin. This article describes GI and hepatic symptoms of several tickborne diseases - Lyme disease, ehrlichiosis, Rocky mountain spotted fever, tularemia, Colorado tick fever, tickborne relapsing fever, Q fever and babesiosis.
