Efficacy of amitraz acaricide footbaths against cattle and goat tick infestations on sites in Highveld and Lowveld regions of Zimbabwe

Parasite Epidemiology and Control
Ticks cause significant economic losses in the Zimbabwean livestock sector. Conventional control methods such as plunge dipping or hand spraying are costly, water-intensive, and often impractical, particularly during dry seasons. This study evaluated the

Estimating the seroprevalence of Mycobacterium bovis infection in a wild deer population in southwest England

Veterinary Record, EarlyView.
Abstract Background In England, transmission of Mycobacterium bovis between cattle and certain species of free‐roaming, wild deer has been implicated in some endemic bovine tuberculosis (bTB) regions. However, there are still data and knowledge gaps regarding the role of deer in the epidemiology of this disease.

High-resolution melt (HRM) analysis for detection of SNPs associated with pyrethroid resistance in the southern cattle fever tick, Rhipicephalus (Boophilus) microplus (Acari: Ixodidae)

International Journal for Parasitology: Drugs and Drug Resistance, 2019
The southern cattle fever tick, Rhipicephalus (Boophilus) microplus, is the most economically important ectoparasite of cattle worldwide. A limitation for sustainable control and eradication is the emergence of acaricide resistance among tick populations.

Babesiosis in cattle and ixodid tick distribution in Dasenech and Salamago Districts, southern Ethiopia

Scientific Reports, 2022
Babesiosis, caused by protozoan parasites of the genus Babesia, and ixodid ticks are considered to be one of the most important causes that result in significant economic losses in cattle production worldwide, including in Ethiopia.

Improving manual tagging of camera trap videos for wildlife studies: a visual assistance tool applied to the endangered huillin Lontra provocax

Wildlife Biology, EarlyView.
In the last decades, the use of camera traps for wildlife studies has increased significantly due to advancements in technology leading to cost reduction and improved reliability. They facilitate the study of wild animals in their natural environment in a minimally invasive manner, eliminating the need for researchers to remain in the field for long ...

Location intelligence unveils seasonal spatiotemporal pattern shifts of habitat use and selection by cattle across a South Texas coastal landscape infested with Rhipicephalus microplus

Current Research in Parasitology and Vector-Borne Diseases
Knowledge gaps on the dynamics of cattle fever tick-cattle-habitat-climate interactions in South Texas and their influence on the efficacy of treatments to eliminate infestations with the Rhipicephalus (Boophilus) microplus prevent optimal interventions ...

Goats as alternative hosts of cattle ticks

Onderstepoort J Vet Res, 2007
The objective of this study was to compare the presence on goats and cattle of adult ticks that usually infest cattle. To this end ticks collected from sets of five goats were compared with those collected from sets of five cattle at 72 communal dip-tanks in the eastern region of the Eastern Cape Province. Amblyomma hebraeum was present on goats at

Experimental assessment of large mammal population estimates from airborne thermal videography

Wildlife Biology, EarlyView.
Wildlife resource management requires reliable, fast, and affordable methods of surveying wildlife populations to develop and adaptively adjust policies. Thermal video from drones can yield high rates of detection over large areas with relative speed and safety.
