Bacterial membranes enhance the immunogenicity and protective capacity of the surface exposed tick Subolesin-Anaplasma marginale MSP1a chimeric antigen

Ticks are vectors of diseases that affect humans and animals worldwide. Tick vaccines have been proposed as a cost-effective and environmentally sound alternative for tick control. Recently, the Rhipicephalus microplus Subolesin (SUB)-Anaplasma marginale MSP1a chimeric antigen was produced in Escherichia coli as membrane-bound and exposed protein and used to protect vaccinated cattle against tick infestations.

Gene expression changes in the salivary glands of Anopheles coluzzii elicited by Plasmodium berghei infection

Malaria is a devastating infectious disease caused by Plasmodium parasites transmitted through the bites of infected Anopheles mosquitoes. Salivary glands are the only mosquito tissue invaded by Plasmodium sporozoites, being a key stage for the effective parasite transmission, making the study of Anopheles sialome highly relevant. RNA-sequencing was used to compare differential gene expression in […]

Anopheles gambiae and A. stephensi Immune Response during Plasmodium berghei Infection Uncovered by Sialotranscriptomic Analysis

Malaria is caused by parasites of the genus Plasmodium that are transmitted through the bite of female mosquitoes of the genus Anopheles. Responsible for high mobility and mortality rates around the world, this protozoan disease is most common in the tropical and sub-tropical regions. Herein, using a pure transcriptomic data analysis approach on mosquito salivary […]

Reduction of Mosquito Survival in Mice Vaccinated with Anopheles stephensi Glucose Transporter

Despite the fact that recent efforts to control/eradicate malaria have contributed to a significant decrease in the number of cases and deaths, the disease remains a global health challenge. Vaccines based on mosquito salivary gland antigens are a potential approach for reducing vector populations and malaria parasites. The Anopheles AGAP007752 gene encodes for a glucose transporter that […]

Guidelines for the Direct Detection of Anaplasma spp in Diagnosis and Epidemiological Studies

The genus Anaplasma (Rickettsiales: Anaplasmataceae) comprises obligate intracellular Gram-negative bacteria that are mainly transmitted by ticks, and currently includes six species: Anaplasma bovis, Anaplasma centrale, Anaplasma marginale, Anaplasma phagocytophilum, Anaplasma platys, and Anaplasma ovis. These have long been known as etiological agents of veterinary diseases that affect domestic and wild animals worldwide. A zoonotic role […]
