The epidemiology and geographic distribution of relapsing fever borreliosis in West and North Africa, with a review of the Ornithodoros erraticus complex (Acari: Ixodida). [PDF]

PLoS ONE, 2013
BACKGROUND: Relapsing fever is the most frequent bacterial disease in Africa. Four main vector / pathogen complexes are classically recognized, with the louse Pediculus humanus acting as vector for B. recurrentis and the soft ticks Ornithodoros sonrai, O.

Detection of African Swine Fever Virus in Ornithodoros Tick Species Associated with Indigenous and Extralimital Warthog Populations in South Africa

Viruses, 2022
We investigated the possibility that sylvatic circulation of African swine fever virus (ASFV) in warthogs and Ornithodoros ticks had extended beyond the historically affected northern part of South Africa that was declared a controlled area in 1935 to ...

Inventory and update on argasid ticks and associated pathogens in Algeria

New Microbes and New Infections, 2018
Argasid ticks include vectors of relapsing fevers caused by Borrelia spp. in humans, and they can transmit arboviruses and other bacterial pathogens. Knowledge about soft ticks (Ixodida: Argasidae) in Algeria is incomplete, and distribution data need to ...

First Data on Ornithodoros moubata Aquaporins: Structural, Phylogenetic and Immunogenic Characterisation as Vaccine Targets [PDF]

, 2022
Ornithodoros moubata transmits African swine fever and human relapsing fever in Africa. The elimination of O. moubata populations from anthropic environments is expected to improve the prevention and control of these diseases.

Tick-Tac-Foe: When Ticks, Trade, and Zoonotic Pathogens Align in African Wet Meat Markets. [PDF]

Public Health Chall
ABSTRACT Zoonotic diseases account for over ∼60% of infectious diseases and present a significantly growing fatality threat in Africa. Live and wet markets (LWMs) in Africa function as key economic venues that support human livelihoods through social interaction and trade in food stuff, including meat and other animal‐based products.

Ornithodoros (Ornithodoros) huajianensis sp. nov. (Acari, argasidae), a new tick species from the Mongolian marmot (Marmota bobak sibirica), Gansu province in China

International Journal for Parasitology: Parasites and Wildlife, 2019
A new argasid species, belonging to the subgenus Ornithodoros, namely, Ornithodoros (Ornithodoros) huajianensis was described for the first time based on the females, males and nymphs. The morphological features of each stage in the life cycle are unique,

Novel symbionts and potential human pathogens excavated from argasid tick microbiomes that are shaped by dual or single symbiosis

Computational and Structural Biotechnology Journal, 2022
Research on vector-associated microbiomes has been expanding due to increasing emergence of vector-borne pathogens and awareness of the importance of symbionts in the vector physiology.

Prevalence and Identification of Livestock Tick by Sex Ratio and Host in Tehran Province. [PDF]

Vet Med Sci
This study identified tick species infesting livestock and poultry in Tehran Province, revealing a female‐biased sex ratio and sheep as the most infested hosts. Rhipicephalus sanguineus sensu lato was the dominant species. These findings underscore the need for host‐targeted tick control to mitigate disease transmission and economic losses.

A proteomic approach to the identification of salivary proteins from the argasid ticks Ornithodoros moubata and Ornithodoros erraticus [PDF]

Insect Biochemistry and Molecular Biology, 2007
The saliva of ticks contains anti-haemostatic, anti-inflammatory and immunomodulatory molecules that allow these parasites to obtain a blood meal from the host and help tick-borne pathogens to infect the vertebrate host more efficiently. This makes the salivary molecules attractive targets to control ticks and tick-borne pathogens.

Borrelia hispanica in Ornithodoros erraticus, Portugal [PDF]

Clinical Microbiology and Infection, 2012
Tick-borne relapsing fever (TBRF) is a spirochetal infection caused by the genus Borrelia. The disease is distributed in the Old and New World with many different species reported. In Europe, TBRF is caused by B. hispanica transmitted to man by Ornithodoros erraticus, a soft tick usually found in old premises to shelter pig herds.
