Objective: This study was conducted to determine hematological reference ranges and morpho¬logical characteristics blood cells in healthy captive Sri Lankan fresh water turtle and tortoise species. Materials and Methods: Following turtle species, namely, Melanochelys trijuga parkeri (n = 06), M. trijuga thermalis (n = 06), and Lissemys punctata punctata (n = 06) and a tortoise species Geochelone elegans (n = 06) were evaluated. Blood smears were stained using LeishmanGram staining protocol. The differential white blood cell counts and morphology were assessed using the standard protocols. Results: Both red blood cells and their nuclei were irregular in M. trijuga parkeri, whereas M. trijuga thermalis had oval-shaped and the nuclei were irregular in shape. L. punctata punctata and G. elegans had oval-shaped red blood cells and their nuclei were round in shape. In terms of differential counts, heterophils were the most abundant leukocyte type in all the species. Melanochelys trijuga parkeri had the highest heterophils value of 55% and the lowest value of 48.5% was recorded with G. elegans. Lymphocytes count was significantly high in G. elegans. Characteristic morphological features were observed in different leukocytes. In terms of thrombo¬cytes, M. trijuga thermalis and L. punctata punctata had single platelets, whereas M. trijuga park¬eri and G. elegans had platelets as clumps. Thrombocytes are ellipsoidal with centrally located dark-stained nuclei and their cytoplasm is clear. Conclusion: The findings in this study can be used as the reference values in the assessment of health of the above species and also will be useful in future hematological studies related to these species.

Objective: This study was considered to explore the possible impacts of drinking water quality from different sources on the bioavailability of doxycycline. Materials and Methods: Sixty-four tap and ground drinking water samples collected from poultry farms were scrutinized for their water quality limits (TH, pH, total dissolved solids, electrical con¬ductivity, Clˉ, Ca⁺², Na⁺, and Mg⁺²) and heavy metals concentrations (Zn, Fe, Cu, and Ni). An in vitro study was conducted by adding the therapeutic concentrations of doxycycline to all tested water samples, and allowed to interact for 1 h, 3 h, 5 h, and 8 h followed by re-estimation of doxycycline concentrations after each contact time using thin layer chromatography. Results: The therapeutic concentration of doxycycline was decreased in tap water samples by 1.92%, 9.63%, 22.42%, and 30.83% for the aforementioned contact times, respectively, while the corresponding reduction percentages in ground water samples were 2.14%, 17.14%, 28.57%, and 40.09%. However, the control samples had never showed any recorded decrease in their doxy¬cycline concentrations overall contact times. All measured concentrations of doxycycline were significantly lower in tap and ground water than those of control at all times of contact. Both pH, Mg⁺² showed significant positive correlations with decreasing values of doxycycline in water. Conclusion: Different drinking water sources reduce the concentrations of doxycycline in vitro in a time dependent manner, which can be attributed to their different physico-chemical parameters, i.e., pH and Mg⁺² ions. This emphasizes the role of water quality on the stability of antibiotics concentrations administrated via drinking water. [J Adv Vet Anim Res 2019; 6(4.000): 438-444]

Objective: The objective of this study was to employ real-time or quantitative polymerase chain reaction (q-PCR) using novel species specific primer (SSP) targeting on mitochondrial cytochrome-b of wild boar species (CYTBWB2-wb) gene for the identification of non-halal meat of wild boar meat (WBM) in meatball products. Materials and Methods: The novel SSP of CYTBWB2-wb was designed by our group using PRIMERQUEST and NCBI software. DNA was extracted using propanol-chloroform-isoamyl alcohol method. The designed SSP was further subjected for validation protocols using DNA isolated from fresh meat and from meatball, which include specificity test, determination of efficiency, limit of detection and repeatability, and application of developed method for analysis of commercially meatball samples Results: The results showed that CYTBWB2-wb was specific to wild boar species against other animal species with optimized annealing temperature of 59°C. The efficiency of q-PCR obtained was 91.9% which is acceptable according to the Codex Allimentarius Commission (2010). DNA, with as low as 5 pg/μl, could be detected using q-PCR with primer of CYTBWB2-wb. The developed method was also used for DNA analysis extracted from meatball samples commercially available. Conclusion: q-PCR using CYTBWB2-wb primers targeting on mitochondrial cytochrome-b gene (forward: CGG TTC CCT CTT AGG CAT TT; Reverse: GGA TGA ACA GGC AGA TGA AGA) can be fruitfully used for the analysis of WBM in commercial meatball samples.

Objective: This study aimed to explore the phytochemical constituents and anthelmintic activities of four Cassia spp. leaves against Haemonchus contortus. Materials and Methods: The extracts were prepared from four species of Cassia spp. (C. siamea, C. fistula, C. surattensis, and C. spectabilis). Phytochemical screening of the extract was done based on the Harborne method. Evaluation of the anthelmintic activities against H. contortus was done in vitro using infective larvae (L3) migration inhibition assay (LMIA). Measurement of larvae migrating was conducted through a nylon filter with a pore size of 20 μm. The doses of Cassia spp. extract implemented were 25, 50, 100, and 200 mg/ml. Results: Tannins, alkaloids, phenol hydroquinone, flavonoids, steroids, triterpenoids, and sapo¬nins were present in all the extracts, whereas alkaloids were absent in C. fistula. No triterpenoids were found in C. surattensis and C. spectabilis. Movement of H. contortus larvae was significantly inhibited after exposure to Cassia extracts at various dosage levels (p < 0.05). The test results using LMIA on L3 H. contortus showed the lowest inhibition in the negative control. Among the species of Cassia, the C. surattensis (at 200 mg/ml) showed the highest (p < 0.05) inhibition level on the larvae. The latter result corresponded to the effect of albendazole. Conclusion: Compared to other Cassia spp., C. surattensis exhibited the highest inhibition against L3 H. contortus. However, the inhibition effect of C. surattensis was still lower as compared to albendazole. [J Adv Vet Anim Res 2019; 6(2.000): 236-240]

Objective: This study was aimed at evaluating the effect of fermentation using Chrysonillia crassa and Monascus purpureus on nutritional qualities, antioxidant, and antimicrobial activities of the used rice as a poultry feed ingredient. Materials and Methods: The used rice was soaked, steamed, and spread on a tray to cool. Suspension of M. purpureus or C. crassa was inoculated on the steamed used rice, and then mixed thoroughly. Afterward, the mixture was spread out on the tray, which was then covered with an aluminum foil. It was aerobically incubated for 7 and 4 days for the M. purpureus- and C. crassa-inoculated used rice, respectively. Subsequent to sun drying, the fermented used rice was grounded and analyzed. Results: Crude protein and ash contents were higher (p < 0.05) in the used rice fermented with C. crassa or M. purpureus than in the unfermented. Conversely, carbohydrate content was lower (p < 0.05) in the fermented compared with the unfermented. Gross energy and energy from fat were higher (p < 0.05) in the used rice fermented with M. purpureus than the unfermented. Amino acids L-methionine, L-serine, L-glutamic acid, L-valine glycine, L-leucine, L proline, L-threonine, L-histidine, and L-Sistine were higher (p < 0.05) in M. purpureus-fermented used rice than in C. crassa-fermented and the unfermented used rice. However, amino acids L-isoleucine, L- alanine, L-lysine, and L-tryptophan were higher (p < 0.05) in the used rice fermented with both C. crassa and M. purpureus, compared with the unfermented. L-tyrosine content was higher (p < 0.05) in M. purpureus-fermented used rice than in the unfermented. Furthermore, the antioxidant activities of the fermented products were higher (p < 0.05) than that of the unfermented. In addition, the antimicrobial activities of the fermented products against Staphylococcus aureus were higher (p < 0.05) than that of the unfermented used rice. Conclusion: In conclusion, the used rice fermented using C. crassa and M. purpureus improved the nutritional quality, as well as the antioxidant and antimicrobial activities of the products.

Objective: House musk shrew (Suncus murinus), a small experimental animal with low body fat, may be a possible model for human lipodystrophy. Leptin is an adipocyte-derived hormone thought to have an important role in the pathophysiology of lipodystrophy. The objectives of this study were to clarify the structure and distribution of suncus leptin. Materials and methods: To determine the primary structure of suncus leptin, we cloned the suncus Lep cDNA using the rapid amplification of cDNA ends method. The obtained amino acid (aa) sequence was compared with other mammals and the protein structure prediction was performed. Results: The suncus Lep cDNA encodes 170 aa. The putative suncus leptin precursor has a predicted signal peptide of 21 aa, and the mature leptin comprises 149 aa. The mature leptin is 75%82% homologous to that of other species. Insertion of the three aa, VPQ, not seen in other mammals was found. This VPQ insertion is thought to be due to a nucleotide insertion of nine bases by slippage-like microindels. The predicted 3D structure of suncus leptin exhibited a typical four a-helix structure, however, the VPQ region protruded compared with human leptin. LepmRNA expression was observed only in white and brown adipose tissues. Conclusion: This study revealed the structure and distribution of suncus leptin. Because the addition of VPQ, which is not found in other mammals, was observed, suncus leptin attracts attention to its physiological action, and to the possibility of being a model of human lipodystrophy.

Objective: The present study was performed for isolation, identification, and molecular detection of Avipoxvirus [Turkeypox virus (TPV), Fowlpox virus (FPV), and Pigeonpox virus (PPV)] from field outbreaks in some selected areas of Mymensingh division, Bangladesh. Materials and Methods: A total of 60 suspected cutaneous nodular samples (10 TPV, 20 PPV, and 30 FPV) were collected. The samples were then subjected to isolation and identification by chicken embryo propagation followed by confirmation using polymerase chain reaction (PCR). Results: The TPV, FPV, and PPV were successfully isolated and identified from the nodular samples using embryo propagation and PCR technique targeting pox virus p4b gene. Out of 10 Turkeypox suspected field samples, five (50%) were positive for TPV. Similarly, among 30 Fowl pox suspected field samples, 12 (40%), and out of 20 Pigeonpox suspected field samples, eight (40%) were found to be positive for FPV and PPV, respectively. The overall prevalence of avipox (TPV, FPV, and PPV) virus infections in Mymensingh division was 41.67% (n = 25/60). Conclusion: This study has shown that TPV, FPV, and PPV are circulating in Mymensingh division. The isolated TPV, FPV, and PPV field isolates can be used as vaccine candidates to develop an effective vaccine for effective controlling of the avipox in Mymensingh division and surrounding areas.

Objective: In this study, we investigated the potential immune-enhancing effects in addition to anti-oxidative stress properties of commercially accessible Bacillus subtilis supplementation in Barki lambs. Materials and Methods: Twenty apparently healthy weaned Barki lambs were used in this study and distributed randomly into two experimental groups: Negative control group, received control basal diet without any feed supplements and a supplemented group, received control basal diet supplemented with water added to commercially accessible bacilli at 1 gm/l/day for 30 consecutive days. Blood samples were collected from each lamb before starting the experiment (T0), 2 weeks (T15), and 4 weeks (T30) post-supplementation for serum biochemical analyses, total leucocytes and lymphocytes count, and real-time polymerase chain reaction assays. Results: The supplemented group showed a significant increase (p < 0.05) in the total number of leukocytes and the number of lymphocytes, lysozyme activity, reduced glutathione, total antioxidant capacity with a significantly lower malondialdehyde values at T30 and significantly higher levels (p < 0.05) of serum catalase and nitric oxide at T15 as compared with control ones. B. subtilis elicited maximal up-regulation of most of the studied genes compared with the control group. Conclusion: The results herein suggest that B. subtilis could be used as useful nutritional supplements to support the immune system in healthy lambs. [J Adv Vet Anim Res 2019; 6(3.000): 333-340]

Objective: The purpose of this study was to evaluate the clinical outcome of surgical decompression and rehabilitation therapy in dogs with thoracolumbar intervertebral disk herniation (IVDH). Materials and Methods: After surgery, physiotherapeutic rehabilitation was performed by a combination of electrotherapy, infrared therapy, training for standing, deep tendon reflex, and aquatic treadmill exercise. A total of 186 dogs were selected from the hospital records and included in two groups: the rehabilitated group (RG, n = 96) and non-rehabilitated group (NRG, n = 90). Dogs in each group were subdivided into three groups based on a pre-operative clinical severity grading system and those in grades 24 were included in this study. Post-operative neurologic functions, unassisted standing, walking, and the success rate of both groups were evaluated and compared Results: Overall, 86.46% (83/96) of dogs had a successful neurologic outcome in the RG group, which was significantly (p < 0.01) higher than the NRG group 52.22% (47/90). Interestingly, the success rate differed when the preoperative grading system was considered. The success rates of grades 2, 3, and 4 were 97.14% (34/35), 97.33% (42/45), and 43.75% (7/16), respectively, in the rehabilitated groups, whereas in the non-rehabilitated groups, success rates were 82.35% (28/34), 51.85% (14/27), and 17.24% (5/29), respectively. The differences in success rates among the groups according to grading were 14.79%, 41.48%, and 26.51%, respectively, indicating that the proposed rehabilitation therapy is remarkably advantageous for increasing the success rate. Conclusion: Rehabilitation therapy after surgical decompression of thoracolumbar IVDH improves neurologic functions and increases the success rate, especially when the preoperative pathological condition is severe.

Objective: The present study was aimed to evaluate dose-dependent effects of phytobiotic (Galibiotic) supplements in feed on growth performance, hematological parameters, intestinal pH, and gut bacterial population in broiler chick. Materials and Methods: A total of 50 ten day old broiler chicks were divided into five groups, namely, Group A as control (without galibiotic), Group B (galibiotic at 1 gm/kg feed), Group C (gal¬ibiotic at 2 gm/kg feed), Group D (galibiotic at 5 gm/kg feed), and Group E (galibiotic at 10 gm/kg feed). All the birds were reared for 42 days and samples were collected before and after sacrifice. Results: Live body weights showed no significant differences between the groups but overall feed conversion ratios (FCRs) of treatment groups were significantly low in Group E having the lowest. Blood samples collected for hematology differed significantly (p < 0.01) among the different groups. Intestinal pH was lower in treatment groups with Group E having the lowest. Cecal total viable count was highest in Group A and lowest in Group E. The cecal coliform count was low in all the treatment groups. Conclusion: Along with previously published report, it may conclude that the phytobiotic could be used as an alternative to antibiotics due to positive growth performance, lower FCR, carcass quality, and improved gut health of broiler chicks.
