The study aimed for the detection and serotyping of Foot and Mouth Disease virus (FMDV) circulating in Kapasia Upazila, Gazipur district of Bangladesh during 2013. Twelve samples comprising of tongue epithelium (n=8) and inter digital tissue (n=4) were collected from suspected cattle, and inocula were prepared. The inocula were inoculated into confluent BHK-21 cell line for virus propagation. After 3 subsequent passages; progressive cytopathic effects (CPE) specific for FMDV i.e., rounding and flattening of cells, breaking down of the intercellular bridge and finally cell death (almost 100%) were observed; these were indicative of successful virus propagation in the cells. Viral RNA was extracted, and Reverse Transcription Polymerase Chain Reaction (RT-PCR) was performed using three sets of primers corresponding to the serotype and lsquo;O', and lsquo;Asia-1' and and lsquo;A', respectively. Out of the 12 samples, 10 (83.33%) were found to be positive for FMDV, and all of those were of serotype and lsquo;O'. It is concluded that FMDV serotype and lsquo;O' is circulating among the cattle of Gazipur district, Bangladesh. [J Adv Vet Anim Res 2015; 2(3.000): 291-295]

This research work was conducted to investigate the effects of age, sex and breed on the induction of immune response against experimentally prepared inactivated trivalent (type O, A, and Asia-1) FMD vaccine. Twenty six cattle were divided into four test groups (Group A, B, C, and D; 5 cattle in each group) and one control group (n=6) based on breed (local and cross), age (≤12 months and >12 months), and sex (male and female). Test cattle were vaccinated with the experimentally prepared trivalent FMD vaccine. Pre- and post vaccinated sera from the vaccinated cattle were collected upto 63 days, and the sera were tested using liquid phase blocking enzyme linked immunosorbent assay (LPBE) that was specific for FMD serotypes O, A, and Asia-1. Antibody titers of all the pre-vaccinated serum samples were found to be under protection level. The females were found to be more protected (90%; n=9/10) as compared to males (70%; n=7/10). The titers obtained were statistically analyzed using t–test to observe the effects of age, breed and sex. It was observed that the mean values of antibody titer in cattle aging >12 months against O, A, and Asia-1 serotypes were significant (P<0.05) at 21, 49 and 63 days as compared to the values obtained from the cattle aging ≤12 months. In conclusion, the local female cattle aging >12 months showed better immune response towards trivalent FMD vaccine.

This case was carried out to compare the healing process and time for the treatment of mange in goats using a combination of Ivermectin with dexamethasone to the earlier Ivermectin with antihistaminics approach. A 3 ½ years old female Boer cross goat was presented with a complaint of crusty lesions on different parts of the body during a routine farm visit in Selangor, Malaysia. Microscopic examinations of the skin scrapes taken revealed Sarcoptes and Psoroptes sp. of mites, while hematological analysis showed slight leucocytosis, neutrophilia with left shift, monocytosis, hyperproteinemia and hyperglobulinemia. Ivermectin injection at 0.2 mg/kg subcutaneously was administered once every 2 weeks in 4 divided doses, while Dexamethasone injection at 1 mg/10 kg and multivitamin at 10 mg/kg IM for 5 days repeated at alternate weeks. Significant improvement was recorded 6 weeks after commencement of treatment and full recovery at 10 weeks. The current drug regimen proved more effective when compared with previous cases that were treated with a combination of ivermectin and antihistaminics.

Forty adult Friesian cows were presented to the University Veterinary Hospital, Universiti Putra Malaysia with primary complain of lameness. Upon physical examination of the cows, open wounds were found at the distal limbs, dorsal hoof, knee joint, metacarpal region, and udder. Based on history, clinical observation and physical examination, the cause of the lameness was diagnosed as of non-infectious origin; the cattle were affected with chemical burn originated from exposure to lime. The affected cattle were treated similarly to that of the line of open wound treatment; the wound was cleaned with topical application of the mixture of dermapred-iodine-benacillin. Flunixin meglumine dosed at 2.2 mg/kg bwt and Oxytetracycline dosed at 20 mg/kg bwt were given intramuscularly as anti-inflammatory and prophylactic antibiotic, respectively. This case report describes diagnosis of the cause of lameness, and its management in cattle herd caused by lime toxicity for the first time in Malaysia.

Buffaloes mostly suffer from delayed puberty, anestrus, sub–estrus, summer infertility, prolonged inter-calving interval and postpartum uterine disorders. Nesfatin-1 and Leptin are directly or indirectly related with body weight (BW), feed parameters and regulation of puberty. The objective of this study was to investigate the influence of Nesfatin-1 and Leptin in pubertal and non-pubertal Murrah buffalo heifers. The Murrah buffalo heifers (n=13) were randomly selected and divided into two groups; pubertal group (PG) and non-pubertal group (NG). Heifers with plasma progesterone (P4) level of ≥1 ng/mL were classified as PG. Blood samples were collected at fortnight intervals for analysis of plasma Nesfatin-1, Leptin, P4, glucose and non-esterified fatty acids. Body weight, dry matter intake and feed conversion efficiency were recorded at fortnight intervals. The mean (±SEM) plasma Nesfatin-1, Leptin, P4, BW and feed conversion efficiency (%) were significantly (P<0.01) higher in PG as compared to NG. Dry matter intake by the heifers was also significantly (P<0.001) higher in PG than NG. Plasma metabolites (glucose and NEFA) did not differ significantly between the groups. The findings of this study suggest that Nesfatin-1 and Leptin have indispensable role in the onset of puberty in buffalo heifers by affecting BW and feed parameters.

The present work aimed to observe the infection pattern of Bovine herpes virus-1 (BoHV-1) in dairy cattle with reproductive problems in Sudan. A total of 140 samples comprising of vaginal swab (n=97), placenta (n=15), whole blood (n=19), uterine fluid (n=1), and serum (n=8) were collected from 16 dairy herds showing particularly high rate of abortion and infertility in Khartoum State. The samples were used for virus isolation, and were tested by Enzyme-Linked Immunosorbent Assay (ELISA) and polymerase chain reaction (PCR). No virus could be isolated from the samples inoculated for isolation in cell culture. Out of 80 specimens tested by ELISA, 7 (8.75%) were found to be positive, and one sample was doubtful. Using PCR, 11 (10.7%) out of 103 samples were found to be positive. When comparing between two methods for DNA extraction, the DNA extracted by commercial kit was found to be better in quality as compared to the DNA extracted using phenol/chloroform/isoamyl-alcohol method. The study confirmed the presence of BoHV-1 in cattle farms with reproductive problems in Sudan.

The influence of two extraction solvents (ethanol and acetone) and two extraction techniques i.e., hot extraction at 400C and cold extraction at 260C were investigated on the phenolic content and antioxidant activity of extracts from Tamarindus indica seed. The antioxidant activity of T. indica was determined by evaluating 1,1-Diphenyl-2-picrylhydrazyl (DPPH) scavenging activity, ferric reducing power assay (FRAP) and ascorbic acid equivalent content (AAC). The tested sample showed appreciable amounts of total phenolic contents (51.45-71.68 mg GAE/gm of dry extract), DPPH scavenging capacity (61.18-71.17%), IC50 values (98.30-248.60), reducing power (0.6377-0.7702) and total antioxidant capacity (22.75-43.80 AAE/gm) at different solvents and techniques. Current study data shown higher extract yields, phenolic contents, scavenging activity, reducing power and antioxidant activity using ethanol solvent compared to the respective acetone solvent. In addition, higher extract yields and other properties were obtained by hot extraction at 400C compared to the cold extraction at 260C. Present study suggests that ethanol as a solvent and hot extraction technique could be better to preserve the antioxidant properties of tamarind seed. [J Adv Vet Anim Res 2015; 2(3.000): 332-337]

Three different highly consumed fish species from Al-Ahsa market, Saudi Arabia namely Spangled emporer (Lethriuns nebulosus), Red striped seabream (Pagrus major) and Black seabream (Spondyliosoma cantharus) were evaluated for their muscle contents of heavy metals (e.g., Cd and Pb) and trace elements (e.g., Cu, Zn, Fe and Mn). The possible risks associated with their human consumption were also studied. A total of 60 fresh fish samples comprising of 20 samples from each above mentioned fish were collected, and were subjected for determination of heavy metal and trace element contents by Atomic Absorption Spectrophotometry after Microwave Wet Digestion. The results showed that, accumulation patterns of the heavy metals and trace elements followed the order: Fe > Zn > Cu > Mn > Pb > Cd. There were variations among metal contents in the muscles of the three fish species; S. cantharus accumulated the highest levels of Cu, Zn and Mn, while the highest level of Fe could be detected in the muscles of P. major. The concentration of Cd and Pb remained comparable in the muscles of all three fish species. The calculated maximum daily intake (MDI) values were found as 0.0003, 0.0009, 0.0035, 0.0001, 0.0000, 0.0000 mg/day/person for Cu, Zn, Fe, Mn, Cd and Pb, respectively. Conclusively, the present study indicated that, fish muscles contain relatively less burden of heavy metals and trace elements, and no health problem can be raised from human consumption of the examined commercial fishes at Al-Ahsa market, Saudi Arabia.
