Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

Biological Reviews, EarlyView.
ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

Investigating zeta‐cypermethrin resistance stability in California Drosophila suzukii populations

Pest Management Science, EarlyView.
After continuous selection and removal of selection pressure in spotted‐wing Drosophila, zeta‐cypermethrin resistance remained stable over several generations. Following a population bottleneck, zeta‐cypermethrin resistance increased without selection, highlighting the importance of insecticide rotation.

Can we continue research in splenectomized dogs? Mycoplasma haemocanis: Old problem - New insight [PDF]

, 2004
We report the appearance of a Mycoplasma haemocanis infection in laboratory dogs, which has been reported previously, yet, never before in Europe. Outbreak of the disease was triggered by a splenectomy intended to prepare the dogs for a hemorrhagic shock

‘Reservoir dogs’: The emerging zoonotic risk associated with European dog imports to the UK

Veterinary Record, EarlyView.
Abstract Background The movement of dogs from continental Europe to the UK poses a growing public health threat due to the associated risk of disease incursions. Current legislation is insufficient to address the risks and pre‐import control measures are focused only on rabies virus and the fox tapeworm Echinococcus multilocularis. Methods We conducted

The host calcium system contributes to intracellular Rickettsia pathogenesis

Infection and Immunity
Bacteria in the genus Rickettsia are obligate intracellular parasites of the eukaryotic cytoplasm. Pathogenic Rickettsia species are exquisitely evolved to only proliferate within eukaryotic host cells, particularly within endothelial cells of the ...

Rickettsia lusitaniae in Ornithodoros Porcinus Ticks, Zambia

Pathogens, 2021
Rickettsial pathogens are amongst the emerging and re-emerging vector-borne zoonoses of public health importance. Though traditionally considered to be transmitted by ixodid ticks, the role of argasid ticks as vectors of these pathogens is increasingly ...

Pyrexia in juvenile dogs: a retrospective analysis of diagnosis and clinical features of 115 Australian cases

Australian Veterinary Journal, EarlyView.
Pyrexia is a non‐specific clinical sign associated with many diseases in dogs. This case series examines the final diagnoses, breed distribution and outcomes in dogs aged 18 months or under with pyrexia >24 h duration. Medical record databases of 11 Australian emergency and referral hospitals between 1st January 2020 and 31st January 2025 were searched

Diversity of Rickettsia species in collected ticks from Southeast Iran

BMC Veterinary Research
Rickettsia occurs worldwide and rickettsiosis is recognized as an emerging infection in several parts of the world. Ticks are reservoir hosts for pathogenic Rickettsia species in humans and domestic animals.

Amblyomma imitator Ticks as Vectors of Rickettsia rickettsii, Mexico

Emerging Infectious Diseases, 2010
Real-time PCR of Amblyomma imitator tick egg masses obtained in Nuevo Leon State, Mexico, identified a Rickettsia species. Sequence analyses of 17-kD common antigen and outer membrane protein A and B gene fragments showed to it to be R. rickettsii, which
