A study was conducted to investigate the serological prevalence of Border Disease Virus (BDV) antibodies in newly introduced Dorper sheep flocks at Debre Birhan Agricultural Research Center (DBARC), Amhara Region, Ethiopia. Blood samples were collected from the jugular vein of 186 sheep in the research center and the serum was decanted and sent to the National Animal Health Diagnostic and Investigation Center, Sebeta, Ethiopia for laboratory examination. All serum samples were examined using blocking ELISA test with a sensitivity of 94.3% and specificity of 93.7% to detect antibodies for BDV. Of these, 55 (29.57%) tested sero-positive and the rest 131 (70.43%) tested sero-negative for BDV antibodies. The sero-prevalence of sheep born in the research center was found at 23.97% (29/121) whereas the sero-prevalence of those sheep imported directly from abroad was found at 40% (26/65). In this research, a higher prevalence of BDV antibodies were recorded in the imported sheep than in the sheep which are born in the research center and the difference in prevalence between the two groups was found statistically significant (P<0.05). Therefore, it is of utmost importance to study the status of the disease from indigenous breeds of sheep and utilize more sensitive tests such as RT-PCR.

Polycyclic aromatic hydrocarbons are a group of lipophilic compounds that can be generated during the preparation of food items at elevated temperatures. They are regarded as potentially genotoxic and carcinogenic to human beings, related to increased incidence of breast and colorectal cancers, oxidative DNA injury, and bad effects on children neuro-differentiation. Thus, they are considered a public health concerns. A total of thirty samples of grilled beef steak, beef kofta and chicken (ten each) were collected from different restaurants. The samples were extracted by magnesium sulfate and sodium acetate in acetonitrile then purified in magnesium sulfate, primary, secondary amine and silica gel, and finally measured by gas chromatography-mass spectrometry (GC-MS). Benzo[a]pyrene was recorded with the highest average level (3.63µg/kg) in grilled kofta samples, but it was not detected in chicken samples. On the other hand, PAH4, PAH8 and ?PAHs content were more abundant in grilled beef steak (5.32, 9.97 and 56.91µg/kg). Meanwhile, they recorded the least concentrations of grilled chicken from different restaurants. Furthermore, benzo[a]pyrene exceeded the permissible limits of the European Commission and Egyptian National Food Safety Authority in grilled kofta samples; further studies are needed to investigate the limits of exposure to these harmful compounds from meats and other food items.

Staphylococcus aureus (S. aureus) is a commensal bacterium associated with serious infections in men and animals. Recently, multidrug-resistant (MDR) strains of S. aureus especially the so-called methicillin-resistant S. aureus (MRSA), represent a serious challenge that hinders the control of infections in man and animals. This study aimed to monitor milk samples from mastitic cows and vaginal and nasal swabs from dogs for the incidence of S. aureus. In addition, the isolates antibiogram profiles were assessed to determine the extent of MDR and MRSA existence among the recovered isolates. Out of 260 samples, 29 (11%) S. aureus isolates were recovered with the highest incidence in milk samples (15/90, 17%), followed by vaginal swabs (8/90, 9%) and nasal swabs (6/80, 7%). Identification of the isolates was confirmed by PCR amplification of 16S rRNA gene sequence. Twenty S. aureus isolates were tested against seven antibacterial agents. Surprisingly, all the twenty isolates were MRSA and three bitch vaginal isolates were MDR. The findings of this study call for more research and cooperation between authors interested in assessing the MRSA and MRD bacterial incidence in both medical and veterinary fields. The cooperation will augment the challenge of disseminating MRSA and MDR staphylococci from animals to humans and vice versa.

The current study investigates to develop a convenient technique for preparation of a dog skeleton without any unpleasant smell, cracking, crumbling or discoloration of bones by using a combination of commercially available detergent and Hydrogen peroxide (H2O2). Specimens were skinned and immersed in a pre-heated 10-liter detergent solution at 50°C to 60°C for 2-3 hours then left for 12 hours. Maceration was deemed completed when any remaining soft tissue was easily removed under running tap water or by soft brush. Then the bones were kept for bleaching with 3% H2O2 for 24-48 hours and allowed to dry properly in the sun. It is shown that the detergent maceration was remarkably faster compared to the traditional burial, insect, hot or cool-water methods, which requires up to several days. In this entire process, skeletons were prepared and installed in correct conformation in only about 92 hours (less than four days). In contrast, the whole maceration was completed in 15 hours (boiling and cooling). On the other hand, the longest time was taken for bleaching and drying purposes, which were 2 days, respectively. The method investigated here for the preparation of skeletal materials in an essentially odorless way, which has shown to be more convenient (faster, easier, safer, and cheaper) compare to previous models in the fields of veterinary anatomy. We believe this projects result will help improve the preparation and preservation technique of skeletons for gross anatomical studies in veterinary institutions.

Poultry products (meat and egg) are some of the common/cheap sources of protein in Africa but the issue of Antimicrobial Resistance due to the inappropriate use of antibiotics in birds is threatening the poultry production subsector and causing serious public health concerns. As such, there is a need to find alternatives (phytogenic) to antibiotics that can improve animal health and reduce antibiotic use by farmers. The study aimed to determine the effect of the graded level of turmeric (Curcuma longa) on the liver enzymes of broilers. The study was conducted with 120 one-day-old broiler chicks (Cobb 500) fed turmeric (Curcuma longa) powder as supplement were used for the experiment (7 weeks). The birds were reared on deep litter system and were randomly allotted to four (4) equal dietary groups (TC, T1, T2, and T3) fed turmeric powder levels of 0, 50, 100, and 150 g/25kg feed for seven (7) weeks. Blood samples were collected at the end of the experiment for laboratory (serum biochemical) analysis; each dietary group contained three replicates with 10 birds each. The results showed that the concentration of total protein (TP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were not affected statistically (P> 0.05) in groups treated with turmeric powder when compared with the control group. In contrast, the activity of alkaline phosphatase (ALP) was affected statistically (P< 0.05) across the group. The study concludes that turmeric positively affected some serum biochemical parameters; although further research is required to elucidate its effect at different inclusion levels on other biochemical parameters.

Despite widespread immunizations, infectious bronchitis (IB) remains a significant issue in the Egyptian poultry industry. Multiple IBV genotypes, GI-1, GI-13, GI-16, and GI-23 have been continually circulating among chicken flocks in Egypt, inducing a substantial economic loss to the poultry sector. In addition, live attenuated vaccines representing classical and variant strains can control IBV in Egypt, mainly H120 and 793B. The H120 vaccine is widely spread and offers inadequate protection against heterotypic IBVs in the field. Therefore, a homologous live-attenuated VAR2 vaccine was developed from the Egyptian variant-2 strain Eg/1212B/2012.IB. Variant II vaccine protects against the homologous IBV challenge under experimental and field circumstances. In this study, an experimental trial was performed to simulate field practices such as heterologous vaccination of day-old specific pathogen-free chicks with IBV H120 vaccine (representing GI-1) and IB Var 2 vaccine (representing GI- 23). The current study aimed to determine the existence of nucleotide and amino acid variations within the S gene in isolated viruses following ten passages in the same bird. The deduced amino acid sequence of the S gene indicated viruses isolated from the 6th and 10th passages were identical and shared (96 %) and (83 %) identities with the IB variant II vaccine and H120, respectively. However, amino acid substitutions were observed at 26 positions in the N terminal domain (S1) and S2 is conserved compared to IB Var 2 vaccine. Most amino acid modifications occurred in the receptor binding domain (RBD) of the S1 gene. HVR2 has seven amino acid changes compared to the IB Var II vaccine. Isolates of P6 and P10 lacked IBV glycosylation site at position 139 which was detected in IBV/EG/1212B/2012 as well as IB variant II vaccine. The study also revealed no evidence of recombination between the two used live vaccines.

Riemerella anatipestifer (R. anatipestifer) infection and duck virus hepatitis (DVH) are enormous dangers for the duck industry and its investment. So, in the current study, a combined inactivated vaccine against both of them was prepared to combat their adverse effect. One hundred and thirty-three ducks of one-day-old of age were used and grouped randomly into four groups. Group (1) was vaccinated with R. anatipestifer vaccine, group (2) was vaccinated with DHV vaccine, group (3) was vaccinated with the prepared combined vaccine of both and finally, group (4) was kept as a negative control. Vaccination was at one day old of age. The vaccinated groups with Riemerella vaccine had 72.7% protection against challenges with the virulent strain with the highest antibody titers in 6th week as measured by the indirect Hemagglutination test. The control group had 90.9% mortality when challenged against R. anatipestifer, with no detectable antibody titers. DVH-vaccinated groups exhibited their highest serum-neutralizing antibody titers by the 5th and 6th weeks post-vaccination. The Control group had no detectable antibody titers against DVH. Statistically, it was clear that there were no significant differences between the results of different groups vaccinated with combined or single vaccines of the same agent. Briefly, combined vaccines of R. Anatipestifer and duck viral hepatitis have harmonized effects with the priority to decrease the stress on birds and workers. Besides its efficiency, the economic side as providing one-shot vaccines instead of each one separately.

This study aims to determine the role of bee pollen in improving the reproductive efficiency of quail males raised at high density. The total number was 288 birds at 7 weeks old, randomly distributed to 6 experimental groups. The 1stgroup was placed at a rate of 21 birds /m2; 2nd group was placed at a rate of 21 birds/m2 and addition of bee pollen 20 g/kg feed, the 3rd group was at a rate of 21 birds / m2 addition of bee pollen 30 g/kg feed, the 4th group was high density 75 birds/m2; 5th group was high density75 birds/m2 and supplemented with bee pollen 20 g/kg feed, and the 6th group was high density 75 birds/m2 and supplemented with bee pollen 30 g/kg feed. The results showed that adding 20g and 30g of bee pollen to the diet of 21 birds caused a significant increase in testosterone hormone. In contrast, the high density of birds caused a significant decrease in testosterone, sperm count and live sperm accompanied by an increase in the dead and deformed sperm. Furthermore, decrease in body weight. Adding 20g and 30g of bee pollen to the high density of birds resulted in a significant increase in testosterone, sperm count, and live sperm accompanied by a reduction in dead and deformed sperm and an increase in body weight. The study concluded that the high density of the birds numbers had a negative impact on the bird reproductive efficiency and body weight while adding bee pollen to the diet improved quail male body weight and reproductive efficiency.

Salmonellosis is a major global pathogen in the poultry industry and is a significant public health concern. Ducks are known to be carriers of Salmonella. Therefore, monitoring salmonellosis is the most important strategy for preventing the disease. An experimental design was planned to study the pathogenicity of two Salmonella strains. One hundred and fifty chicks were divided into three groups; group one was inoculated with the Salmonella enteritidis strain, group two was inoculated with the Salmonella typhimurium strain, and group three was UN inoculated. Symptoms, postmortem lesions and mortality rate were recorded. The chick growth performance parameters were also determined. Using ANOVA for statistical analysis, there was a significant difference in body weight, body gain, feed consumption, and feed conversion ratio between the two infected groups and the blank group (uninoculated group). In this study, the prevalence of Salmonella enteritidis was (1.73%) and Salmonella typhimurium (0.43%) in imported ducklings in Egypt. Both Salmonella strains were subjected to an antimicrobial sensitivity test. It showed that Salmonella enteritidis had a 60% antimicrobial resistance profile and Salmonella typhimurium had a 20% antimicrobial resistance profile. Furthermore, genotypic characterization was performed and the seven virulence genes(stn, avrA, sopB, ompF, invA, Mgtc, Ssaq) were found. New pathological lesions of Salmonella infection were discovered, such as skull hemorrhage at 3 days and 6 days of age, and a liver similar to a button shape in necropsied infected chicks with Salmonella typhimurium at 21 days of age. Furthermore, hemorrhagic spots were observed on the duodenum. In the presence of Salmonella, Clostridium perferingens was discovered in a bacteriological investigation of duodenal lesions samples from infected chicks. At 30 days of age, administration of acetic acid (1%) as an alternative tool for controlling Salmonella. In conclusion, salmonellosis is a risk factor for necrotic enteritis, and using acetic acid to eliminate salmonella infection is insufficient.

The dromedary camel is mainly found in the tropics of Africa, the Middle East, and the Indian sub-content, where it is of great importance to nomadic and rural communities to provide high-quality animal protein in the form of milk and meat and as a means of transportation. In the Arabian Gulf region, the camel gained popularity and importance recently as a racing animal. The camel is well adapted to harsh environments characterized by inadequate water and vegetation, high ambient temperature, and rough terrain. Camels are working animals suited to their desert habitat and are a vital means of transport for humans and cargo, especially for rural farmers. There are three surviving species of camel. Camels originated in North America and eventually spread across Beringia to Asia. They survived in the Old World, and eventually, humans domesticated them and spread them globally. However, the literature on the physiological parameters of the camel is scanty. This review aims to provide a general overview of the physiological features of the camel and an update on the available studies of physiological and behavioural features of the camel and the effects of thermal environmental conditions on some physiological responses.

Acetylcholinesterase is required as an enzyme to counteract the effects of acetylcholine. The aim of the study is to assess how amitriptyline and Ashwagandha affect the acetylcholinesterase gene in rat salivary glands. Forty healthy albino rats were divided randomly into four equal groups: Group I (control) received distilled water for 30 days. Group II received amitriptyline (10mg/kg) for 30 days. Group III received ashwagandha watery root extract (200mg/kg) orally for 30 days and Group IV received the combination of amitriptyline orally and ashwagandha root extract orally for 30 days. Rats in each group were sacrificed after day 30 and salivary glands were dissected for measurement of the acetylcholinesterase gene using a Polymerase Chain Reaction technique (PCR). Acetylcholinesterase gene measurements reveal an increase in groups treated with amitriptyline alone (1.55±0.11) and in the group treated with a combination of amitriptyline with Ashwagandha (1.92±0.16), in comparison with the control group. There were no discernible differences between the Ashwagandha treated group (1.073± 0.25) compared to the control group (0.76±0.19).In conclusion, Amitriptyline alone and, when combined with Ashwagandha cause transcription of the acetylcholinesterase gene.

The case includes a 7-month-old puppy poodle applied to a private hospital for weakness, tremors and seizure attacks. Clinical examination findings were normal. From blood samples, biochemical parameter measurements were carried out. The values of alkaline phosphatase (ALP), alanine aminotransferase (ALT), ammonia and fasting serum bile acids were high and the blood urea nitrogen (BUN) value was low. Ultrasonographic examination, shunted vein in the liver to the vena cava caudalis, that is colour Doppler observed the extrahepatic shunt and turbulent flow in this shunted. Depending on clinical, laboratory (hemogram and biochemistry) and ultrasonographic observations, portosystemic shunt (PSS) was diagnosed and controlled one month after the treatment was recommended. The medical treatment included a hepatic formula diet (liver care), lactulose 0.5 ml/kg three times a day, metronidazole 15 mg/kg twice a day, S-adenosyl Methionine 15 mg/kg once a day, 400 international unite (IU) vitamin E once a day for 30 days. When turbulent flow is observed in the shunted vein in the liver to vena cava caudalis, ultrasound examination with color Doppler can help diagnose portosystemic shunt. After the treatment, clinical improvement was observed and clinical symptoms of hepatic encephalopathy including seizures and tremors, disappeared completely. Determination of turbulent flow with colour Doppler and decreased portal flow velocity with portal hypertension with PW-Doppler ultrasonography are important for the diagnosis of the portosystemic shunt. It was concluded that medical treatments might help before surgical treatments in portosystemic shunts.

Camels play an important role in social life and the economy. So, the current study was planned to detect the blood constituents and milk components of Maghrebi She-Camel in different parties. Thirty pregnant she-camels were inseminated and became pregnant in this study during the first quarter of 2019; thirteen pregnant she-camel managed to give calving successfully during March 2020. According to multiple parities, they were classified into three groups; (1-2 parities), (3-4 parities) and (5-6 parities). Blood measurements included hematology, substances, ions and milk measurements included yield and components. No significant differences between all groups for all hematological measurements. The overall mean of daily milk production was significantly higher after eight weeks of lactation than at the beginning of lactation. No significant results were shown in milk fat, lactose and protein neither parties nor lactation period. Milk total solid significantly was in its lowest values eight days of parturition for the first and second parties and was at its highest values for the third and fourth parties. A significant difference in ash% was found between experimental parties for the first eight days of lactation and after eight weeks. In general, those insignificant differences in blood parameters, milk productivity and composition might indicate animal health and stability.

Lumpy Skin Disease (LSD) is a notifiable vector-borne disease transmitted by blood-feeding insects affecting cattle populations. LSD is a severe disease that is leading to economic losses. In this study, we displayed the prevalence of LSD in Egypt through retrospective and survey studies to point out the possible hazards of this serious disease. The 2006–2018 passive surveillance data were obtained from OIE-Wahis. A survey was conducted on 326 cattle, collected from 40 villages in 2017, using a structured questionnaire. Between 2006 and 2018, a total of 577 positive LSD outbreaks were reported. For spatial distribution, the Delta region showed the highest significant prevalence of 88% in the 2006 outbreak. Afterwards, Upper Egypt recorded the highest LSD prevalence between 2014 and 2018. The temporal distribution showed an alternative seasonal prevalence of LSD. In the cross-sectional study, the Delta had the highest prevalence, followed by Upper Egypt. Between the seasons, autumn had the highest prevalence followed by winter. Animals over the age of two years had the highest prevalence of risk factors. Dairy animals had a high significant prevalence. Housing animals in the open, the presence of farms near markets and repeated visits to markets, all had a high prevalence. The abundance of biting-flies significantly increased the prevalence. Almost all of the farmers were significantly unaware of the disease. The absence of periodic cleaning, animal isolation, and proper carcass disposal, all significantly increased LSD prevalence especially in unvaccinated animals. In conclusion, the retrospective and cross-sectional studies showed that LSD is an endemic disease with both spatial and temporal distributions. In addition, the survey pointed out the husbandry and biosecurity breaches that magnify LSD prevalence. Therefore, raising disease awareness and applying strategic prevention and control measures are the practical pillars against LSD.
