Evaluation of the real-time PCR, rose bengal test (RBT), competitive ELISA, and complement fixation test (CFT) was done on 335 camels sera. Real-time PCR, classified 335 camel serum samples to 268 (80%) as positive and 67 (20%) as negative. Real-time PCR, using species specific primers, distinguished 94/104 serum samples due to B. abortus, 4/104 samples due to B. melitensis and 6/104 due to mixed infection. The results of serological tests revealed that modified mRBT75 using 75 µl of serum, detected the highest number of positive samples 271 (80.9%), while 262 (78.2%), 257 (76.7%), 253 (75.5%) and 245 (73.1%) samples were found to be positive for brucellosis using CFT, cELISA, mRBT50, and RBT25, respectively. Compared to other serological tests, the CFT proved to have the best results in the criteria of test validations, namely; specificity (88%), PPV (96.9%), NPV (80.8%), PLR (7.9), NLR (0.06) and DOR (133.8). The Kappa (K) statistic agreements values between real-time PCR and rose bengal (RBT25), modified (mRBT50), (mRBT75), cELISA and CFT was 0.562 (± 0.053), 0.613 (± 0.052), 0.725 (± 0.048), 0.710 (± 0.047) and 0.801 (± 0.041), respectively. The authors recommend the use of real-time PCR on camel sera to confirm the disease.

The experiment applied on four groups of calves, each of four calves. Three calves from each group were vaccinated with one of the following attenuated vaccines: Lumpy skin disease vaccine (LSD), Romanian sheep pox (RSP) vaccine, Held goat pox (HGP) vaccine and dual (bivalent) vaccine of SPV and GPV. All vaccines were evaluated by estimating the cellular immunity using lymphocyte blastogenesis measured by XTT assay, and humeral immunity using serum neutralization and ELISA tests of vaccinated calves. The NI coincided with the ELISA antibody results and corroborated the results of cell mediated immunity which demonstrated the capacity of LSD and dual vaccines to induce immune response higher than SP vaccine and GP vaccines. In conclusion, the current study proved that the LSD and dual vaccines were highly immunogenic than the RSP and HGP vaccines, and dual vaccine could be safely used for vaccination of cattle against lumpy skin disease.

Brucellosis is considered an economically important highly contagious and zoonotic bacterial disease of water buffaloes. Control of brucellosis in buffaloes is very important for public health. The efficacy of control program depends on the detection and eradication of infected animals coupled with vaccination and application of biosecurity. This study was carried out to control the brucellosis in buffalo farm in Assuit Governorate, Egypt during the period from April 2015 to August 2016. Out of 620 unvaccinated buffaloes, 87 (14.03%) aborted. Moreover, 90/620(14.51%), 82/620(13.22%), 82/620(13.22%), and 80/620 (12.9%) buffaloes were serologically positive by BAPA, RBPT, m SAT and Riv.T, respectively. Three isolates were differentiated as Brucella melitensis, biovar 3, one strain isolated from one vaginal swap out of 10 Riv.T. positive recently aborted buffaloes (10%) and two strains were isolated out of ten milk samples of Riv.T. positive buffaloes (20%). Eighty serological positive buffaloes to Riv.T were culled from the herd, while 60 serological negative heifers were vaccinated by Brucella abortus S 19 vaccine, with a dose of 3-8×109 cfu/5ml and monitored for serological titer for 240 days. After 6 months of vaccination, the number of serologically positive calves declined marginally to 50 (83.33%), 40 (66.67%), 50 (83.33%), 0 (0%), 40 (66.67%) and 0 (0%) by BAPA, RBPT, mSAT, CFT, iELISA and cELISA, respectively. Three successive serological tests every three weeks were done by screening tests, BAPA and RBPT and confirmed by Riv.T. At the end of the control program, all examined buffaloes were serologically negative. Application of biosecurity in the farm was applied by the sanitary disposal of aborted material and application of proper disinfectants at its recommended work strength and contact time.

The current study was conducted to investigate the incidence of metritis and endometritis in dairy cows. Moreover, to determine the collective impact of metritis and endometritis in dairy farms on reproductive performance and milk yield. A total number of 246 Holstein cows divided into three groups was included in the current study.One of these groups as control group and the second and the third groups were including those cows diagnosed with acute postpartum metritis and chronic endometritis, respectively. The obtained results showed that endometritis possessed severe negative effects on postpartum reproductive performance of the studied cows compared to normal cows. Moreover, the impact of this disease was higher in premiparous cows in comparison with com their pleuriparous herd-mates. Days to first estrus tended (P=0.06) to be increased in premiparous cows suffering from endometritis (89.19±12.12 days) compared to normal cows (59.45±3.30 days) or those suffering from acute metritis (65.37±4.92 days). While in pleuriparous cows, the negative effects of endometritis did not show any tendency for prolonged days to first estrus, when compared to normal cows. Endometritis had significantly (P<0.01) negative impacts on postpartum cyclicity in premiparous cows (89.19±12.12 days), compared to 56.32±3.15 days in pleuriparous cows. Endometritis, significantly negatively (P<0.05) impacted days to first AI in both premiparous cows (105.63±12.95 days, compared to 65.97±2.63 days for normal cows and pleuriparous cows (76.19±3.64 days). A nearly similar trend was observed for endometritis and metritis regarding their potential negative impacts on number of inseminations per conception in both premiparous and pleuriparous cows. Regarding to, days open, diseases like endometritis was associated with significantly (P<0.01) higher days open in both premiparous and pleuriparous cows. Meanwhile, advancing parity was associated with significantly (P<0.05) higher days open for cows suffering from endometritis only.

In order to estimate the ameliorating effects of alpha lipoic acid (ALA) on the nephropathy of diabetes mellitus (DM) associated with oxidative stress, this study performed in 18 adults male rabbits were divided into 3 equal groups, the group-I was regard as control while group-II Induced DM only by intravenously single dose (150 mg/kg b.w.) of alloxan-monohydrate; group-III was induced DM by intravenously single dose of (150mg/kg b.w.) of alloxan-monohydrate and then treated by (10mg/kg b.w.) daily of ALA intraperitoneally for 4 weeks. The biochemical results showed significant (P≤0.05) decreased of the serum values of GSH, CAT and SOD as well, significantly (P≤0.05) increased of MDA, peroxynitrate, creatinine and BUN of group-II when compared to control; also the result of group-III showed nonsignificant (P˃0.05) differences of GSH, SOD, MDA, creatinine, BUN and peroxynitrate when compared to control. The histopathological and histochemical results of kidney of group-II showed moderate thickness of basement membrane of glomeruli with compressed capillaries as well infiltration of glyco-proteinaceous materials in glomeruli and around renal tubules with some vacuolation of these tubules and mesangial cells; while the results of group-III showed normal architectures with very mild degree of vacuolation of few renal tubules in addition to disappearance of glyco- proteinaceous materials in this group; in conclusion, ALA had a dual protective effects on nephropathy by scavenging the oxidative stress free radicals and enhanced insulin metabolism.

Assessment of the sperm membrane functional status appears to be a significant marker for the fertilizing capacity of spermatozoa. The hypo osmotic swelling test (HOST) is one of the best methods to evaluate sperm membrane integrity. In the current study, we used DW and hypo osmotic solutions of 50 and 100mOsm/l of dextrose/NaCl, NaCl, sucrose and fructose. Based on the results, Among the dextrose/NaCl, NaCl, sucrose, and fructose solutions and DW, Maximum numbers of swollen of bull frozen-thawed spermatozoa were observed with DW and dextrose/NaCl solution at 50 mOsm with average response by 61.20±8.677 and 47.90±10.181 respectively. The HOST response at 3 and 60 min for all of solutions were positively correlated to each other and there was no significant difference between the responses to the HOST at 3 and 60 min after incubation in all of solutions. The significant correlation was observed between motility and dextrose/NaCl at 50 mOsm, sucrose 50 and 100 mOsm, NaCl 50 mOsm and DW. The high relationship was between motility and DW and dextrose/NaCl at 50 mosm. There was no significant correlation between DW and all of hypoosmotic solutions with staining of the spermatozoa by eosin/nigrosin. In conclusion, the water test can be efficiently used for the evaluation of the functional integrity of the plasma membrane of bull frozen-thawed spermatozoa. The hypoosmular solution of dextrose/NaCl at 50 mOsm is a good medium to evaluate bull frozen spermatozoa. The used of HOST and motility are better tests to evaluate bull frozen thawed sperm than eosin-nigrosin. The short HOST procedure (3 min) is suitable method for evaluating of membrane integrity of bull frozen/thawed spermatozoa

The current study investigated the comparison of the biochemical composition of the common carp Cyprinus carpio L. which collected from four different sources in Basrah city; Shatt Al-Arab river at Abul- Khasib by using gill nets, earthen ponds at the University of Basrah campus, fish cages at Al-Hartha district and cooled fish imported from the Islamic Republic of Iran.
