babesiosis/protease

BACKGROUND Hematophagous mosquitos and ticks avoid host hemostatic system through expression of enzyme inhibitors targeting proteolytic reactions of the coagulation and complement cascades. While most inhibitors characterized to date were found in the salivary glands, relatively few others have been

Babesiosis is a tick-borne protozoonosis caused by Babesia, which can cause fever, hemolytic anemia, hemoglobinuria, and even death. Babesia microti is a parasite found in rodents and can be pathogenic to humans. In this study, the full-length cDNA of a B. microti cysteine protease (BmCYP) was

Malaria and babesiosis are bloodborne protozoan infections for which the emergence of drug-resistant strains poses a threat. Our previous phage display cDNA screens established the essentiality of Plasmodium falciparum signal peptide peptidase (SPP) in asexual development at the blood stage of

Babesiosis is a tick-borne, zoonotic disease caused by species of the intraerythrocytic protozoan Babesia. It is distributed all around the world and affects various domestic and wild animals, mainly cattle. Recently, the cysteine protease enzyme, babesipain-1 from Babesia bigemina has been

Babesia bigemina is a protozoan parasite that causes babesiosis, a disease with a world-wide distribution in mammals, principally affecting cattle and man. The unveiling of the genome of B. bigemina is a project in active progress that has already revealed a number of new targets with potential

Babesiosis is a tick borne disease (TBD) caused by parasites of the genus Babesia, with considerable worldwide economic, medical, and veterinary impact. Bovine babesiosis and other TBDs were considered responsible for 50% of the deaths of cattle that occurred in Mozambique in the first year after

Cysteine proteases are essential hydrolytic enzymes present in the majority of organisms, including viruses and unicellular parasites. Despite the high sequence identity displayed among these proteins, specific structural features across different species grant distinct functions to these

Ixodes ricinus is the most widespread and abundant tick in Europe, frequently bites humans, and is the vector of several pathogens including those responsible for Lyme disease, Tick-Borne Encephalitis, anaplasmosis, babesiosis and bartonellosis. These tick-borne pathogens are transmitted to

Babesia ovis, a tick-transmitted intraerythrocytic protozoan parasite, causes severe infections in small ruminants from Southern Europe, Middle East, and Northern Africa. With the aim of finding potential targets for the development of control methods against this parasite, sequence analysis of its

Ixodid ticks are ectoparasites responsible for the transmission of a large number of bacterial, viral, and protozoan pathogens to animals and humans. As long-term blood-pool feeders, the digestion of host blood is critical to their development as well as to the establishment of the sexual cycle of

The Babesia bovis and B. bigemina apicomplexan protozoa in conjunction with the rickettsia Anaplasma marginale are intraerythrocytic pathogens that are responsible for the most prevalent and costly tick borne diseases (TBD's) of cattle worldwide. These organisms are historically associated as they

BACKGROUND Rhipicephalus haemaphysaloides, a hard tick, is a common ectoparasite and can be found in many countries. It is recognized as the primary vector of bovine babesiosis in the south of China. During blood feeding, the tick's salivary glands secret numerous essential multifunctional proteins.

BACKGROUND Babesia orientalis is an obligate intraerythrocytic protozoan parasite of the buffalo (Bubalus bubalis, Linnaeus, 1758) transmitted by the tick Rhipicephalus heamaphysaloides. It is the causative agent of water buffalo babesiosis, one of the most important pathogens of water buffalo in

We evaluated the inhibitory effects of pepstatin A and mefloquine on the in vitro and in vivo growths of Babesia parasites. The in vitro growth of Babesia bovis, B. bigemina, B. caballi, and B. equi was significantly inhibited (P < 0.05) by micromolar concentrations of pepstatin A (50% inhibitory
