Functional genomics of tick vectors challenged with the cattle parasite Babesia bigemina

Ticks are obligate hematophagous ectoparasites considered as vectors of animal diseases, having a huge economic impact in cattle industry. Babesia spp. are tick-borne pathogens that cause a disease called babesiosis in a wide range of animals and in humans. Control of tick infestations is mainly based on the use of acaricides, which have limited efficacy […]

Rhipicephalus bursa sialotranscriptomic response to blood feeding and babesia ovis infection: Identification of candidate protective antigens

Abstract Ticks are among the most prevalent blood-feeding arthropods, and they act as vectors and reservoirs for numerous pathogens. Sialotranscriptomic characterizations of tick responses to blood feeding and pathogen infections can offer new insights into the molecular interplay occurring at the tick-host-pathogen interface. In the present study, we aimed to identify and characterize Rhipicephalus bursasalivary gland […]

Comparative efficacy, toxicity and biodistribution of the liposomal amphotericin B formulations Fungisome®and AmBisome®in murine cutaneous leishmaniasis

Fungisome® (F), a liposomal amphotericin B (AmB) product, is marketed in India as a safe and effective therapeutic for the parasitic infection visceral leishmaniasis. Its potential in the treatment of cutaneous leishmaniasis (CL), a disfiguring form of the disease affecting the skin, is currently unknown. Here, we report the evaluation of the efficacy of F in […]

Antiplasmodial activity of tick defensins in a mouse model of malaria

Malaria is a mosquito-borne disease affecting millions of people mainly in Sub-Saharan Africa, Asia and some South American countries. Drug resistance to first-line antimalarial drugs (e.g. chloroquine, sulfadoxine–pyrimethamine and artemisinin) is a major constrain in malaria control. Antimicrobial peptides (AMPs) have shown promising results in controlling Plasmodium spp. parasitemia in in vitro and in vivo […]

Recombinant protein production: A case study research report

Plasmodium spp. and Leishmania are the causing parasites to malaria and leishmaniasis, two widely spread diseases that are still responsible for millions of cases worldwide every year. The proteins in study, AGAP007752-PA (Anopheles gambiae) and α-tubulin (Plasmodium spp. and Leishmania infantum), are thought to be relevant in decreasing parasite transmission by affecting their life cycles. […]
