Evidence and mechanisms of immunosuppression in tick infestations

Genetic Analysis: Biomolecular Engineering, 1999
The abundance and ubiquity of ticks from ancient times long ago suggested that they have eluded host immunity. In the last 15 years, several authors have demonstrated suppression of the Th1 responses (cell-mediated immunity), and sometimes the Th2 responses (humoral immunity), subsequent to tick infestations in laboratory and natural models.

A longitudinal study of avian pox in a small passerine, the Dunnock (Prunella modularis)

Ibis, EarlyView.
Long‐term, longitudinal studies of disease in wild bird populations are rare. Diseases are important determinants of bird survival and may spill‐over into other species including livestock and, in some cases, humans. Avian pox is a globally distributed disease, resulting from infection by viruses in the genus Avipoxvirus (APV).

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

Insect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

Year-round tick exposure of dogs and cats in Germany and Austria: results from a tick collection study

Parasites & Vectors, 2023
Background Ticks and tick-borne diseases play a major role in companion animal health. Additionally, the European tick fauna is changing, for instance due to the spread of Dermacentor reticulatus, displaying a higher likelihood of winter activity than ...

Genetic and Phenotypic Correlations Among Growth, Disease Occurrence, and Reproductive Performance From Calf to Heifer in Girolando Dairy Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Girolando breed, a cross between Holstein (Bos taurus) and Gir (Bos indicus), is the primary choice for dairy production in Brazilian tropical regions, as it combines high productive potential with adaptation to the tropical environment.

Tick vaccines and the transmission of tick-borne pathogens

, 2007
Ticks transmit pathogens that cause diseases which greatly impact both human and animal health. Vaccines developed against Boophilus spp. using Bm86 and Bm95 tick gut antigens demonstrated the feasibility of using vaccines for control of tick ...
