Tick-borne zoonoses in the Order Rickettsiales and Legionellales in Iran: A systematic review.

PLoS Negl Trop Dis 2018 09 11;12(9):e0006722. Epub 2018 Sep 11.

Department of Pathobiology, School of Veterinary Medicine, Shiraz University, Shiraz, Iran.

Background: Tick-borne zoonoses in the Order Rickettsiales and Legionellales cause infections that often manifest as undifferentiated fevers that are not easy to distinguish from other causes of acute febrile illnesses clinically. This is partly attributed to difficulty in laboratory confirmation since convalescent sera, specific diagnostic reagents, and the required expertise may not be readily available. As a result, a number of tick-borne zoonoses are underappreciated resulting in unnecessary morbidity, mortality and huge economic loses. Read More

Ticks Tick Borne Dis 2018 03 21;9(3):687-694. Epub 2018 Feb 21.

Wildlife Ecology & Health group (WEH) and Servei d'Ecopatologia de Fauna Salvatge (SEFaS), Departament de Medicina i Cirurgia Animals, Universitat Autònoma de Barcelona (UAB), Bellaterra, Barcelona, Spain; Departament de Ciència Animal, Escola Tècnica Superior d'Enginyeria Agraria (ETSEA), Universitat de Lleida (UdL), Lleida, Spain. Electronic address:

Ruminant livestock is the main reservoir of Coxiella burnetii (Cb), but little is known about the role of wildlife and ticks in its epidemiology. The Iberian ibex (Capra pyrenaica, Schinz 1838) population of "Ports de Tortosa i Beseit" (NE Spain) suffers intense tick infestations and low reproduction rates. This study aims to (1) assess the relationship between infection in ibexes (detection of serum antibodies and/or of Cb DNA in tissues) and Cb DNA presence in ticks hosted by the same ibexes; and (2) identify Cb associated risk factors.

Two mice models for transferability of zoonotic bacteria via tick vector.

Acta Virol 2017;61(3):372-376

Spotted fever and typhus-related diseases caused by rickettsiae, Lyme borreliosis induced by spirochetes from Borrelia burgdorferii sensu lato complex, and Q fever evoked by Coxiella burnetii, are important zoonoses occurring worldwide. In order to study the pathogenesis of these infections, the efficacy of vaccines from the perspective of protection against the pathogens, pathogen - pathogen interactions during co-infections or pathogen-vector-host interrelationship, a suitable animal model should be established. In this study, we evaluated two mouse models - the C3H/N and Balb/c strains for susceptibility to infection and ability to transmit the pathogens via tick vector and to reveal the potential interactions between various bacterial tick-borne agents.

DHR-ICMR Guidelines for diagnosis & management of Rickettsial diseases in India.

Indian J Med Res 2015 Apr;141(4):417-22

Writing Committee of the DHR-ICMR Guidelines for Diagnosis & Management of Rickettsial Diseases in India; Indian Council of Medical Research Task Force on Development of Guidelines for Diagnosis & Management of Rickettsial Diseases, India.

Rickettsial diseases, caused by a variety of obligate intracellular, gram-negative bacteria from the genera Rickettsia, Orientia, Ehrlichia, Neorickettsia, Neoehrlichia, and Anaplasma, belonging to the Alphaproteobacteria, are considered some of the most covert emerging and re-emerging diseases and are being increasingly recognized. Among the major groups of rickettsioses, commonly reported diseases in India are scrub typhus, murine flea-borne typhus, Indian tick typhus and Q fever. Rickettsial infections are generally incapacitating and difficult to diagnose; untreated cases have case fatality rates as high as 30-45 per cent with multiple organ dysfunction, if not promptly diagnosed and appropriately treated.

Natural foci diseases as a stable biological threat.

Arch Immunol Ther Exp (Warsz) 2014 Dec 19;62(6):445-7. Epub 2014 Oct 19.

Department of Epidemiology, Lviv National Medical University, L'viv, Ukraine,

The key aspects of the natural foci of especially dangerous diseases as a type of biological threats are presented. Approaches to epidemiological surveillance and control to the spread of the agents of especially dangerous diseases on endemic areas are described for zoonosis that has a medical value. The knowledge of specific design of tools for the implementation of epidemiological surveillance, monitoring and evaluation of natural foci diseases in developing countries is low; accordingly, little is known on the ecology and transmission dynamics for the agents of especially dangerous diseases.

Laboratoire MIVEGEC, UMR 5290-224 CNRS-IRD-UM1-UM2, Centre de Recherche IRD, 34090 Montpellier, France.

The obligate intracellular bacterium Coxiella burnetii is the etiological agent of Q fever, a widespread zoonotic disease whose most common animal reservoirs are domestic ruminants. Recently, a variety of Coxiella-like organisms have also been reported from non-mammalian hosts, including pathogenic forms in birds and forms without known effects in ticks, raising questions about the potential importance of non-mammalian hosts as reservoirs of Coxiella in the wild. In the present study, we examined the potential role of globally-distributed seabird ticks as reservoirs of these bacteria. Read More
