Objective: This study aimed to elucidate the proteome profile of the 150 kDa protein isolated from the subordinate follicle of Bali cattle (Bos sondaicus/javanicus). Some researchers have revealed several factors in the follicular subordinate with a 150 kDa protein substance, which play important roles in the bovine ovulation. Materials and methods: In the present study, subordinate follicles (~ 5 mm in diameter) were collected from 10 female Bali cattle from slaughterhouses in Taliwang, Sumbawa of West Nusa Tenggara Province, Indonesia. The follicular liquid was pooled; fractionated using SDSPAGE 10%, the 150 kDa band was sliced and then analyzed using MALDI-TOF/TOF-MS. Results: Mascot search results significantly revealed the presence of four species of proteins/peptides. Of the four peptides, two were predominant i.e. complement C3 and anti-testosterone antibody, which both were 100% identical to complement C3 and anti-testosterone antibody of Bos Taurus cattle. Conclusion: Complement C3 and anti-testosterone antibody are present in the follicle fluid of Bos sondaicus/javanicus cows. These findings are novel in Bali cattle follicles.

Objective: The present study was carried out to identify the associated Salmonella and Escherichia coli in betel leaves (Piper betle), and to develop an effective method to remove those microbes. Materials and methods: Betel leaves were collected from local and whole sale markets, and borouj (cultivation place). Salmonella and E. coli were isolated and identified by cultural, morphological, and biochemical tests followed by confirmation by polymerase chain reaction (PCR) targeting the genus specific 16S rRNA genes. Antibiogram of the isolated bacteria was performed by disc diffusion method. Different concentrations of Salmosan-A Soln were used to remediate the contaminating bacteria keeping the quality of betel leaves for longer periods. Results: Total Salmonella counts in the betel leaves were 3.9×105, 4.9×106, 3.5×104, 1.1×103 and 1.5×103 CFU/mL, while E. coli counts were 5.5×107, 6.3×107, 4.4×105, 3.3×103 and 3.1×103 CFU/mL in the betel leaves collected from K.R. market, Kewatkhali Bazaar, whole sale market, borouj in Kushtia and borouj in Natore, respectively. Antibiogram study revealed that the isolated bacteria were sensitive to doxycyclline, ciprofloxacin, chloramphenicol and cefotaxime. Application of 0.3% Salmosan-A Soln was found to be the most effective and suitable, where [J Adv Vet Anim Res 2018; 5(1.000): 73-80]

Objective: This study aimed to observe the changes in anatomical pathology, histopathology, and histomorphometry of uterine horn in Aceh cattle with repeat breeding (RB). Materials and methods: In this study, five uterine horns were collected from fertile Aceh cattle (N1, N2, N3, N4, and N5) and Aceh cattle with RB (RB1, RB2, RB3, RB4, and RB5). Changes in the anatomical pathology of uterine horn were observed prior to histopathological preparations. The results were analyzed descriptively. Results: The observation of anatomical pathology revealed that the uterus of fertile cattle was yellowish white with horn-like shape consisting of hollow muscles, while RB cattle were reddish-pale. Furthermore, uterine horn swelling with purulent exudate was observed in the uterine horn of RB1 and RB4, while swelling with serous exudates was found in RB2, RB3, and RB5. Thin-walled uterine horn with caruncular atrophy was observed only in RB3. Histopathological observations showed erosion and hyperplasia of endometrial columnar epithelial and uterine glands in RB1, RB2, RB4, and RB5. Atrophy of uterine gland was found in RB3 and edema of caruncular was observed in RB1 and RB4. In addition, hemorrhage and inflammatory cell infiltration (neutrophils, lymphocytes, and macrophages) were found in all RB cattle. Histologically, cow uterus is divided into three layers, endometrium, myometrium, and perimetrium with the uterine gland found in the endometrium. Histomorphometric measurements found that the uterine horn wall (endometrial, myometrial, and perimetrium) of RB cattle were thicker than of fertile Aceh cattle, 208.06 ± 39.90 vs. 187.39 ± 29.09 μm, 400.138 ± 51.96 vs. 277.91 ± 42.88 μm, and 23.59 ± 9.67 vs. 18.53 ± 4.40 μm. However, the endometrial gland diameter of RB cattle is smaller than that of fertile Aceh cattle, 4.04 ± 0.88 vs. 4.99 ± 1.37 μm. Conclusion: The changes in anatomical pathology and histopathology of the uterine horn of Aceh cattle with RB indicate endometritis which caused by subacute and chronic bacterial infections. Endometritis causes disrupted blood circulation, which is characterized by hemorrhage, edema, and thickening of the endometrium, myometrium, and perimetrium, resulting in an increased diameter of the endometrial gland in RB Aceh cattle.

Objective: The aim of this research is to study the effectiveness of mosquito magnet (MM) for reducing mosquitoes (Diptera) populations in coastal areas. Materials and methods: The study sites are in the coastal area of Samut Songkhram province, Thailand, which is divided into two locations; one that is 2 km and another that is 4 km in distance from the sea. We used the Mosquito Magnet® Independence (MMI) trap for effective field testing in Samut Songkhram Province, Thailand. Traps were placed 100 m away from the house (one trap per location) and mosquitoes were collected at night from 6 PM to 6 AM during September and October 2017 (30 days). Results: A total of 2,561 adult mosquitoes, including Anopheles epiroticus Linton & Harbach, Culex quinquefasciatus Say, Cx. sitiens Wiedmann, and Cx. gelidus Theobald were collected by MMI. At a 2-km distance from the sea were captured more mosquitoes per night more than at a 4-km distance (63.63 ± 42.30 vs. 21.70 ± 12.42). The comparison of effectiveness of MMI in two locations of the coastal area was shown to have a statistically significant difference (p < 0.05) and analysis of the correlation between the number of mosquitoes caught in coastal areas, including at a 2- and 4-km distance from the sea, accounting for weather factors, we found that the effectiveness of MMI was not correlated with weather (p > 0.05). Conclusion: Overall, this study demonstrated that MM can be used to control mosquitoes in coastal areas with high efficiency, especially 2 km away from the sea.

Objective: The study was intended to design the new specific primer targeting on mitochondrial D-Loop gene (D-Loop 443 primer) combined with a real-time polymerase chain reaction (PCR) for the analysis of wild boar meat (WBM) in food products of meatball. Materials and methods: The primer was designed and subjected to primer-basic local alignment search tool using National Center for Biotechnology Information software. Validation of real-time PCR using designed primer was performed by evaluation of several performance characteristics which included specificity, sensitivity, repeatability, linearity, and efficiency. Results: The results showed that the D-loop primer could be attached at 60.7°C and no amplification was detected against other species confirming the specificity of the primers. The limits of detection were found to be 4.68 ng and 2.34 ng using DNA extracted from WBM and that extracted from wild boar in meatball product. The D-Loop 443 primer was successfully used for the analysis of commercial meatball samples. Conclusion: The developed method can be proposed as a standard method for the identification of WBM in meatball to support halal products authentication. [J Adv Vet Anim Res 2018; 5(3.000): 361-368]

Objective: Rhipicephalus microplus is a very invasive tick whose control is a current challenge. Its speed of propagation is favored by specific risk factors whose knowledge is an essential prerequisite for a good rather design of strategies to put in place for its control. This study consisted of evaluating the influence of transhumance on the spread of this tick in Benin. Materials and methods: To achieve this objective, two sets of tick sampling were carried out on five animals before and after transhumance in 80 autochthon herds from 8 municipalities in Benin. Results: The abundance of R. microplus varies significantly between breeding type, hosting type, period of ticks collection and between some of their interactions such as: breeding - period, hosting - period and breeding - hosting - period. In addition, the abundance of R. microplus according to each of these factors before transhumance differs significantly from the one observed after transhumance; the parasite load of R. microplus observed before transhumance is much higher than that observed after transhumance. Transhumance contributes to the spread of R. microplus in Benin. Conclusion: It represents a risk factor on which health risk managers could act in terms of surveillance and control of this cattle tick by carrying out the de-parasitage in the health campaign programs of transhumant animals.

Objective: The objective of this research was to assess the suitability of FTIR spectroscopy coupled with multivariate analysis of partial least square regression (PLSR) along with pattern recognition technique of principal component analysis (PCA) for rapid quantitative and qualitative (identification) analysis of dog meat in beef meatball formulation. Materials and Methods: The lipid fraction of meatball was obtained by employing two different extraction techniques, namely Bligh-Dyer and Folch method. FTIR spectral bands correlated with beef fat, pork fat, chicken fat and rat fat were measured, interpreted, and qualitatively analyzed. The small variations among spectra were exploited as a basis tools to differentiate between dog fat and other animal fats. Results: PCA at combined wavenumber regions of 1700-700 cm-1 was capable of identifying dog meat in meatball. These wavenumbers were also used for quantitative analysis of dog meat in meatball using PLSR model. Based on statistical parameters used, namely R2, RMSEC and RMSEP, Folch extraction method offered higher R2 and lower RMSEC and RMSEP than Bligh-Dyer. PCA is succesfully applied for classification between meatball containing dog meat and other meats. Conclusion: FTIR spectroscopy coupled with multivariate analyses of PLSR and PCA was effective means for rapid screening of dog meat in meatball products. [J Adv Vet Anim Res 2018; 5(3.000): 307-314]

Objectives: This study was conducted to assess the prevalence and characterization of Staphylococcus aureus from chicken and quail eggshells and to study the antibiogram of the isolates. Materials and methods: A total of 300 eggs (220 chicken eggs and 80 quail eggs) were collected from different retail shops and farms in Mymensingh district. Swabs taken from the egg surfaces were cultured on Mannitol Salt Agar for the isolation of S. aureus. Polymerase chain reaction was conducted for confirmatory identification of the bacterial species targeting nuc gene, followed by confirmation of methicillin-resistant S. aureus by targeting the mecA gene. Antibiotic sensitivity test of the isolated bacteria was done against commonly used antibiotics by the disk diffusion method. Results: The prevalence of Staphylococcus spp. and S. aureus in the chicken eggshell surface was 20.45% and 10.45%, respectively. Similarly, the prevalence of Staphylococcus spp. and S. aureus in quail eggshell surface was 16.25% and 5%, respectively. Overall, 27 isolates were identified as S. aureus, of which 23 were from the chicken eggshell surface and four from quail eggshell surface. Among the seven isolates tested, overall four (57.14%) were positive for the nuc gene. On the other hand, the mecA gene could be detected in three (50%) S. aureus out of six oxacillin resistant isolates. The antibiogram study indicated that most of the isolates were resistant to the antibiotics under β-lactam group. Conclusion: The present study concludes that chicken and quail egg surface harbor multidrugresistant bacteria which may cause public health hazards, if these antibiotic-resistant bacteria are transferred to a human.
