Cellular immune response of Amblyomma sculptum and Amblyomma americanum to entomopathogenic fungi: Implications for biological tick control

Medical and Veterinary Entomology, EarlyView.
Amblyomma sculptum showed a plasmatocyte‐dominant haemocyte profile. Beauveria bassiana increased plasmatocytes and reduced granulocytes, whereas Metarhizium robertsii did not cause significant changes. Amblyomma americanum showed a granulocyte‐dominant haemocyte profile. Beauveria bassiana reduced total haemocytes and granulocytes. B.

Reevaluating the presence of Rhipicephalus australis (Acari: Ixodidae) in Southeast Asia: A phylogenetic approach based on Cambodian tick samples

Ticks and Tick-Borne Diseases
Morphological variability between Rhipicephalus australis and R. microplus has led to taxonomic ambiguity, leading to species misidentification. Rhipicephalus australis is reported to have a distribution range in Pacific Ocean region extending to several

High prevalence of a host‐associated Anaplasma lineage in wild coatis (Nasua nasua) from the Brazilian Atlantic Forest

Medical and Veterinary Entomology, EarlyView.
Anaplasma sp. DNA was detected in 47.9% of free‐ranging coatis (Nasua nasua) sampled in Iguaçu National Park, southern Brazil. Molecular analyses revealed a genetically distinct Anaplasma lineage infecting coatis, differing from Anaplasma strains detected in associated tick populations.

Identification of a mutation in the para-sodium channel gene of the cattle tick Rhipicephalus (Boophilus) microplus associated with resistance to synthetic pyrethroid acaricides [PDF]

, 2009
Resistance against synthetic pyrethroid (SP) products for the control of cattle ticks in Australia was detected in the field in 1984, within a very short time of commercial introduction.

Tick‐Tac‐Foe: When Ticks, Trade, and Zoonotic Pathogens Align in African Wet Meat Markets

Public Health Challenges, Volume 5, Issue 2, June 2026.
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.

Diversity, Host Attachment Preferences and Role of Tick Rhipicephalus microplus in the Transmission of Bartonella spp. and Rickettsia spp. in Cattle From Southern Benin

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Ticks infesting cattle in Southern Benin were investigated for diversity, attachment preferences and zoonotic bacteria. Among 2210 ticks collected from 540 cattle, Rhipicephalus microplus predominated (79.6%). Ticks mainly attached to ears, axillae and trunk. PCR detection revealed Bartonella spp. and Rickettsia spp., highlighting veterinary and public

Acaricide activity in vitro of Acmella oleracea against Rhipicephalus microplus [PDF]

Parasitology Research, 2014
Cattle tick control has been limited by the resistance of these parasites to synthetic acaricides. Natural products are a possible alternative as they have different mechanisms of action. Acmella oleracea is a native plant with a large cultivated area in the Amazon region and could be easily used for large-scale preparation of a commercial product ...

Ticks on pastures and on two breeds of cattle in the Eastern Cape province, South Africa

Onderstepoort Journal of Veterinary Research, 2011
Many studies on the population dynamics of questing ticks on pastures and of parasitic ticks on cattle have been conducted. Few, however, have attempted to link the two in a single study.

Species composition, diversity and predilection sites of ticks (Acari: Ixodidae) infesting cattle in the Western Highlands of Cameroon [PDF]

Arthropods, 2021
Ticks are haematophagous ectoparasites infesting wilds and domestic animals as well as humans and, are considered after mosquitoes to be the principal vectors for the transmission of various pathogens.
