A rapid and accurate assay for evaluating antibabesial drugs on a large scale is required the discovery of novel chemotherapeutic agents against Babesia parasites. In current study, we evaluated usefulness fluorescence-based determining efficacies compounds bovine equine hemoparasites in vitro cultures. Three different hematocrits (HCTs; 2.5%, 5%, 10%) were used without daily replacement medium. The results high-throughput screening revealed that best HCT was 2.5% parasites 5% Theileria IC50...

Brucellosis is a zoonotic disease that has serious animal welfare and economic consequences worldwide. In mammals, this stealthy intracellular pathogen causes abortion infertility, in humans, it produces terrible febrile illness can progress into long-term condition with implications. The pathogenicity of brucellae based on their ability to survive replicate host cells, which allows them escape from the immune system. gold standard test for diagnosis, demands competence, still isolation...

Background: Cryptosporidium is a common intestine anthroponotic protozoan parasite that affects humans and other animals all over the world. Many different kinds of vertebrates have their gastrointestinal epithelium infected by ubiquitous, obligatory parasites spp. In humans, those with weakened immune systems, including AIDS, are most affected. Particularly prevalent in developing nations, cryptosporidiosis poses further difficulties for underfunded public health system. Humans frequently...

Background and Aim: Paratuberculosis, caused by Mycobacterium avium subsp. paratuberculosis (MAP), is a significant infectious disease affecting livestock, including camels in Saudi Arabia, leading to severe economic losses. Despite its impact, limited genomic studies have been conducted characterize MAP strains their antimicrobial resistance (AMR) profiles. This study aimed (1) the clinical pathological findings of infections camels; (2) determine seroprevalence eastern region Arabia; (3)...

Ovine theileriosis caused by Theileria ovis and lestoquardi is an important infectious disease affecting small ruminants in regions of the tropic subtropic zones. There limited studies about ovine Egypt; so present study aims to assess occurrence Egypt at molecular level.Blood samples were collected from 115 randomly selected sheep, which apparently healthy; ages sampled sheep ranged 1 5 years old, a local breed (barkae balade), showed no symptoms indicating infection with spp. The was...

Klebsiella species is a bacterial organism responsible for serious infections in both animals and people. This study try to spot highlights on the predominance of among camels as well screening some virulence genes. For this purpose, 345 camel samples were taken, including 160 nasal swabs from with respiratory distress, off-feeding, or fever., severe discharge, depression, organ (lung (90), trachea (40), intestine (30), liver (25), collected east west coast border Egypt.
