The aim of this study was to characterize the clinically relevant genital tract disorders of dromedary camels. Reproductive tract examinations were performed via transrectal palpation, ultrasonography and vaginal exploration. The ultrasonic appearance of the reproductive pathology was described and compared with its morphology at laparotomy, after surgical removal, during postmortem examination or upon slaughter. Diagnosis was also confirmed by histopathology. The most frequently encountered follicular structures were larger than typical follicles (56/338, 16...

Snakebite is a significant cause of death and disability in subsistent farming populations of rural India. Antivenom is the most effective treatment of envenoming and is manufactured from IgG of venom-immunised horses. Because of complex fiscal reasons, the production, testing and delivery of antivenoms designed to treat envenoming by the most medically-important snakes in the region has been questioned time to time. In this study, we report successful immunisation of dromedaries (Camelus dromedarius) against the venom of Indian saw-scaled Viper- Echis carinatus sochureki...

Application of assisted reproductive technology in camelidea, such as artificial insemination (AI) and embryo transfer, has been slow in comparison to that for other livestock species. In Egypt, there are few attempts to establish in vitro maturation (IVM) and fertilization (IVF) techniques in dromedary camel. The present study was carried out to produce Sudanese camel embryos using in vitro matured oocytes and epididymal spermatozoa. Dromedary camel ovaries were collected from abattoirs and then, the oocytes were aspirated from all the visible follicles on the ovarian surface (~2-8 mm in a diameter)...

The physical properties of rennet-induced coagulation of preheated camel and cow milk gels (50 and 70 °C for 10 min) enriched with calcium chloride (CaCl2) and hydrogen phosphate dihydrate (Na2HPO42H2O) were evaluated using the dynamic low amplitude oscillatory shear analysis. The storage modulus (G') and loss modulus (G") of camel milk gels showed significant (P < 0·05) lower values than those of cow milk gels. The preheating of camel milk at 50 °C affected negatively the gelation properties, while the preheating at 70 °C prevented the formation of rennet-induced milk gels...

The effect of pH (4.3 or 6.5) and heat treatment (70°C or 90°C for 30min) on the foaming and interfacial properties of α-lactalbumin extracted from camel milk were studied. The increased temperature treatment changed the foaming properties of camel α-lactalbumin solution and its ability to unfold at the air-water interface. At neutral pH, heat treatment was found to improve foamability, whereas at acid pH (4.3) this property decreased. Foams were more stable after a heat treatment at pH 4.3 than at 6.5, due to higher levels of protein aggregation at low pH...

Middle East respiratory syndrome coronavirus (MERS-CoV) is a betacoronavirus which can cause acute respiratory distress in humans and is associated with a relatively high mortality rate. Since it was first identified in a patient who died in a Jeddah hospital in 2012, the World Health Organization has been notified of 1735 laboratory-confirmed cases from 27 countries, including 628 deaths. Most cases have occurred in Saudi Arabia. MERS-CoVancestors may be found in OldWorld bats of the Vespertilionidae family...

Neospora caninum and Toxoplasma gondii are the protozoan parasites with definitive hosts from order Carnivora. Due to vertical transmission, both parasites can cause abortions and neonatal mortality that lead to significant productive and economic losses in the domestic ruminants. The aim of this study was to describe N. caninum and T. gondii seroprevalence in the group of frequently farmed captive exotic ruminants (n = 184) including Bovidae (barbary sheep, bezoar goat, common eland, American bison, water buffalo, and yak) and Camelidae (bactrian camel, guanaco, llama, and alpaca)...

BACKGROUND: Italy is presently facing an increase in immigration from sub-Saharan Africa through the Mediterranean Sea. Case reports of human cystic echinococcosis (CE) have been reported from most sub-Saharan countries. Therefore, an increase in the number of patients with CE coming from these areas in the Italian and European centers for infectious diseases is expected. Unfortunately, the epidemiology of CE in sub-Saharan countries is poorly known, which makes clinical suspicion and diagnosis of such infection difficult in patients coming from these areas...

Heterocyclic amines (HCAs) are formed by cooking protein-rich foods, for instance, meat and fish, and are listed as possible human carcinogens. In the present study, the presence of five potential HCAs (IQ, MeIQ, MeIQx, 4,8-DiMeIQx, and PhIP) in cooked camel meat burgers was analyzed for the first time. The analysis was performed in home-cooked and fast-food burger samples containing food additives. The applied cooking technique for the home-cooked samples was pan frying for a controlled cooking time and temperature...

The hamadryas baboon (Papio hamadryas hamadryas) is the only indigenous species of non-human primates (NHP) found in the Kingdom of Saudi Arabia (KSA). There are no peer-reviewed publications on viral infections of the baboons of KSA. Apart from camels, other animals are likely sources of the novel Middle East Respiratory Syndrome coronavirus (MERSCoV) for humans. We investigated evidence of highly pathogenic coronavirus infections including MERSCoV in a large group of commensal baboons accompanied by feral dogs, on the outskirts of Ta'if city, KSA, in February 2013...

Mimetics of antibody-binding sites represent particularly interesting targets, however they are difficult to identify. In most cases, naturally derived CDR3 peptides show a much lower activity and affinity. In this study, we identified a CDR3 domain antibody with framework 3 (FR3) and FR4 in the flank by screening a lysozyme-immunized phage display VHH library. This antibody has a potent enzyme inhibiting activity and high thermal stability. With sequence alignment and site-directed mutagenic analysis, we found that the cysteine residue at amino acid position 88 in FR3 might play a key role in maintaining the stability of the CDR3 antibody...

Infection with the Apicomplexan parasite Neospora caninum occurs in domestic and wild animals worldwide. This parasite causes significant economic losses in the dairy industry worldwide. The current study was designed to assess the prevalence of N. caninum antibodies in the sera of camels (Camelus dromedarius) from Rakh Mahni, Bhakkar, Pakistan, to better understand the epidemiology of this important cause of bovine abortion in Pakistan. Eighty-one sera samples collected from apparently healthy camels (male = 19, female = 62) were tested for antibodies against N...

Golgi anti-apoptotic protein (GAAP), also known as transmembrane Bax inhibitor-1 motif-containing 4 (TMBIM4) or Lifeguard 4 (Lfg4), shares remarkable amino acid conservation with orthologues throughout eukaryotes, prokaryotes and some orthopoxviruses, suggesting a highly conserved function. GAAPs regulate Ca(2+) levels and fluxes from the Golgi and endoplasmic reticulum, confer resistance to a broad range of apoptotic stimuli, promote cell adhesion and migration via the activation of store-operated Ca(2+) entry, are essential for the viability of human cells, and affect orthopoxvirus virulence...

Eye lenses are exposed to thermal, solar radiations, dryness that enhances cataractogenesis. Some animal lenses contain novel proteins in bulk quantities. ζ-crystallin occurred in three ecologically divergent species, but it's physiological role not known. The truncated variant of ζ-crystallin causes hereditary cataract. Guinea pig ζ-crystallin is temperature-sensitive and rapidly aggregates at 41°C. Camels adopted to survive above 50°C, which raises an interesting question about how it retains lens proteins in the soluble state? Here, we have optimized expression and purification of recombinant camel ζ-crystallin...

The aim of the current study was to improve the selection method of camel oocytes after in vitro maturation by reducing exclusion criteria that were based only on the presence of the first polar body. A combined nuclear and morphometric assessment of camel oocytes after in vitro maturation was included to perform a judgment. The nuclear status of the oocytes, including the presence of the first polar body, meiosis I stage, and lack of nuclear materials, was investigated. The morphometric criteria that comprised the dimensions of each oocyte were as follows: diameter of the whole oocyte, including the zona pellucida (ZPO), zona pellucida thickness (ZPT), ooplasm diameter (OD), the perivitelline space (PVS) area, and PVS diameter...
