The development of innovative targeted therapeutic approaches are expected to surpass the efficacy of current forms of treatments and cause less damage to healthy cells surrounding the tumor site. Since the first development of targeting agents from hybridoma's, monoclonal antibodies (mAbs) have been employed to inhibit tumor growth and proliferation directly or to deliver effector molecules to...

VHH are polypeptides (15 kDa) derived from the variable domain of single heavy-chain antibodies of Camelidae. They represent the smallest antigen-binding fragment of an antibody (human IgG = 150 kDA). VHH are currently being explored for a number of applications. Anti-rabies virus VHH were cloned from lymphocytes of vaccinated llamas and selected for their affinity with the viral spike glycopro...

UNLABELLED Nanobodies are single-domain antigen-binding fragments derived from heavy-chain antibodies that are devoid of light chains and occur naturally in Camelidae. We have shown before that their small size and high affinity and specificity for their target antigen make Nanobodies ideal probes for in vivo tumor imaging. In the present study, we have evaluated the use of Nanobodies as a gene...

Background and Aim Recently, cases of mastitis refractory to treatment have been reported frequently. There are limited routine laboratory investigations on Camelidae infections. Mastitis has been estimated to affect more than 25% of lactating she-camel with up to 70% milk loss. The details of Bacillus spp. pathogenesis in mastitis are not yet fully described. The present study is the first det...

ticks (acari: ixodidae) are obligatory blood feeders and important external parasites of wildlife, domestic animals and humans in tropical and subtropical areas. ticks primarily transmit different pathogenic organisms to livestock and humans, and secondly harm their animal hosts by decreasing blood protein content and nutrients due to partial exsanguinations, induce allergic reaction and someti...
