Some effects of irradiation on the tick Rhipicephalus appendiculatus

Parasitology, 1972
Groups of Rhipicephalus appendiculatus ticks were given single doses of irradiation (range 0·25–16 krad) at different stages in their life-cycle: unfed nymphs, engorged nymphs, moulting nymphs and unfed adults. The effects of irradiation were assessed by evaluating the subsequent performances of the ticks when fed on rabbits.

Sufficient reproduction numbers to prevent recurrent epidemics

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1186-1200, June 2025.
Abstract Current practice in the design and evaluation of control measures in disease ecology and epidemiology, including vaccination, is largely based on reproduction numbers (RNs), which represent prognostic indices of long‐term disease transmission, both in naïve populations (basic RN) and in the presence of prior exposure or infection containment ...

Molecular Profiling of Ticks and Associated Pathogens: First Report of Rickettsia sibirica, Rickettsia slovaca, and Babesia microti in Ticks From Pakistan

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Global distribution of ticks and their associated tick‐borne pathogens (TBPs) presents substantial health concerns for both humans and animals. The present study aimed to investigate the distribution, morpho‐molecular identification, and associated TBPs of diverse tick species collected from Khyber Pakhtunkhwa and Punjab provinces of Pakistan ...

Spatiotemporal Distribution and Meteorological Determinants of Lumpy Skin Disease (LSD) Occurrence in Bangladesh From 2020 to 2023

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Lumpy skin disease (LSD) is a transboundary viral disease affecting cattle and buffaloes caused by LSD virus (LSDV), which belongs to the Capripoxvirus genus. The disease was first detected in Bangladesh in 2019 and has since become endemic. This study focuses on analyzing the spatiotemporal distribution of LSD cases and examining the relationships ...

Pathogens, endosymbionts, and blood-meal sources of host-seeking ticks in the fast-changing Maasai Mara wildlife ecosystem.

PLoS ONE, 2020
The role of questing ticks in the epidemiology of tick-borne diseases in Kenya's Maasai Mara National Reserve (MMNR), an ecosystem with intensified human-wildlife-livestock interactions, remains poorly understood.

The moulting arthropod: a complete genetic toolkit review

Biological Reviews, Volume 99, Issue 6, Page 2338-2375, December 2024.
ABSTRACT Exoskeletons are a defining character of all arthropods that provide physical support for their segmented bodies and appendages as well as protection from the environment and predation. This ubiquitous yet evolutionarily variable feature has been instrumental in facilitating the adoption of a variety of lifestyles and the exploitation of ...
