Ixodid ticks are significant vectors of pathogens affecting both humans and animals. Biological control with natural enemies represents a sustainable tool for managing ticks. However, there is a substantial lack of knowledge about the natural enemies of ticks.

- Tick-borne pathogens (TBPs) in dogs pose a significant global health threat, particularly in developing countries where surveillance is lacking.
- A study involving 230 community dogs in Nepal found that 32.6% were infected with at least one TBP, with common pathogens including Ehrlichia canis and Anaplasma platys.
- The findings suggest that infections in community dogs might pose a risk for transmission to pet dogs and humans, highlighting the need for increased awareness and control measures against these zoonotic parasites.
Yezo virus (YEZV) is an emerging tick-borne virus that causes acute febrile illness. It has been continuously reported in patients and ticks in Japan and China since its first identification in Hokkaido, Japan. While serological tests have demonstrated that YEZV infections are prevalent in wild animals, such as raccoons (Procyon lotor), the determinants of infection in wild animals remain largely unknown.

Ticks Tick Borne Dis

Revealing interactions between ticks and wild animals is vital for gaining insights into the dynamics of tick-borne pathogens in the natural environment. We aimed to elucidate the factors that determine tick infestation in wild animals by investigating ticks on invasive raccoons (Procyon lotor) in Hokkaido, Japan. We first examined the composition, intensity, and seasonal variation of ticks infesting raccoons in six study areas in Hokkaido from March 2022 to August 2023.

- Vector-borne parasite infections are common in both domestic and wild animals, often asymptomatic but potentially fatal, particularly under stress.
- This study focused on the detection and characterization of such parasites in rescued greater one-horned rhinoceroses in Chitwan National Park, Nepal, using advanced molecular techniques on blood samples.
- Results revealed a 75% prevalence of Theileria bicornis, two new haplotypes, and the presence of Wolbachia and filarial nematodes, indicating a need for enhanced parasite surveillance and further research on wildlife diseases in the region.
Many arthropods harbour bacterial symbionts, which are maintained by vertical and/or horizontal transmission. Spiroplasma is one of the most well-known symbionts of ticks and other arthropods. It is still unclear how Spiroplasma infections have spread in tick populations despite its high prevalence in some tick species.

Article Synopsis
- - Malawi has a sizable cattle population of nearly 1.9 million, primarily composed of the indigenous Malawi zebu breed, which makes up over 91% of the population.
- - A molecular survey found that a staggering 92.3% of cattle examined were infected with tick-borne pathogens (TBPs), including significant rates of Anaplasmataceae and piroplasms, highlighting a serious health issue among livestock.
- - The study introduced a multiplex PCR assay for identifying TBPs without needing sequencing, which could aid in managing infections in resource-limited areas where such tools are scarce.
