DISTRIBUTION OF TICKS AND THEIR ASSOCIATION WITH BORRELIA IN SEMNAN PROVINCE

Iranian Journal of Public Health, 1999
A faunistic study was carried out to estimate the frequency and distribution of different species of ticks and their association with intermittent relapsing fever, in 1995. In this study, during a course of 18 months, 78 villages were examined in 4 towns

Identification of Bartonellae in the Soft Tick Species Ornithodoros sonrai in Senegal [PDF]

Vector-Borne and Zoonotic Diseases, 2014
Ticks, belonging to the soft ticks species Ornithodorus sonrai, have been collected from six sites in Senegal and were tested for the presence of Bartonella spp. Initial screening by PCR revealed the presence of these bacteria in ticks from two villages, Soulkhou Thissé (5/8, 62.5%) and Maka Gouye (1/24, 4.2%).

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Seasonal Activity of Ticks and their Importance in Tick-Borne Infectious Diseases in West Azerbaijan, Iran

Journal of Arthropod-Borne Diseases, 2008
Background: West Azerbaijan is considered as a main region for domestic animal breeding. Due to importance of herd as a main host and ticks as a vector of relapsing fever and CCHF, a comprehensive study was undertaken in the region.

Detection of Babesia spp., Theileria spp., and Anaplasma ovis in Ornithodoros lahorensis from southern Xinjiang, China

Journal of Veterinary Research, 2023
Ticks are blood-sucking arthropods that have negative economic impacts and can spread a variety of diseases through their bites. There are few reports on soft ticks (Acari: Argasidae) and tick-borne pathogens in southern Xinjiang, China.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Transovarial Transmission of Borrelia hermsii by Its Tick Vector and Reservoir Host Ornithodoros hermsi

Microorganisms, 2021
Transovarial passage of relapsing fever spirochetes (Borrelia species) by infected female argasid ticks to their progeny is a widespread phenomenon. Yet this form of vertical inheritance has been considered rare for the North American tick Ornithodoros ...

Stiffness‐Activated Stellate Cells Drive Pancreatic Cancer Liver Colonization via GMFG‐TNS4 Signaling

Advanced Science, EarlyView.
Fibrotic liver stiffness activates hepatic stellate cells through Piezo1‐dependent calcium influx and ER stress, promoting EV‐associated GMFG release. Delivered GMFG engages TNS4 in pancreatic cancer cells, triggering FAK/AKT signaling, adhesion, and fatty acid synthesis.

Detection of relapsing fever Borrelia spp., Bartonella spp. and Anaplasmataceae bacteria in argasid ticks in Algeria.

PLoS Neglected Tropical Diseases, 2017
BackgroundArgasid ticks (soft ticks) are blood-feeding arthropods that can parasitize rodents, birds, humans, livestock and companion animals. Ticks of the Ornithodoros genus are known to be vectors of relapsing fever borreliosis in humans.
