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 study was carried out to analyze the various phytochemical properties and to determine the in-vitro antimicrobial activity of Parkia biglobosa methanolic leaf extract against Methicillin-Resistant Staphylococcus aureus (MRSA). Materials and methods: The phytochemical screening and Thin Layer Chromatography (TLC) of the methanol extract were conducted using standard methods. The antimicrobial activity of the P. biglobosa methanolic leaf extract on sheep and human MRSA isolates was investigated by disc diffusion method. The extract was tested at different concentrations of 100, 200 and 400 mg/mL and norfloxacin (10 µg) as control. The MIC/MBC were determined by serial dilution method in broth media. Results: the phytochemical analysis showed the presence of alkaloid, saponins, tannins, cardiac glycosides, flavonoids and terpenoids while TLC result revealed 5 spots with retention factor (Rf) values of 0.14, 0.34, 0.42, 0.56 and 0.66 depicting different component using methanol and chloroform at the ratio of 4:1 as solvent system. The diameter of inhibition zone (DIZ) of the extract on MRSA isolates cultured on agar plate revealed a dose dependent response. The extract had the highest DIZ average replicate value of 20.66±1.76 against human MRSA isolates and 20.66±1.20 was recorded as highest DIZ on the sheep MRSA isolates. Norfloxacin had the highest DIZ of 20.33±0.57 on sheep MRSA isolates and 20.33±1.52 DIZ against human isolates. MIC/MBC revealed the highest values of 6.25 mg/mL/12.5 mg/mL for both sheep and human MRSA isolates. Conclusion: The susceptibility test of crude methanol extract of P. biglobosa leaf has revealed activity against MRSA. Thereby, attesting to the folkloric claim of using P. biglobosa for ethno-therapeutic purposes against infectious diseases in Nigeria and other places. [J Adv Vet Anim Res 2018; 5(2.000): 173-181]

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.

Objective: Salmonella is a widely-reported zoonotic bacterial pathogen and human infection is mostly attributed through direct or indirect contact with chickens. Salmonella Kentucky (S. Kentucky) is one of the motile serovars which has recently been identified from both poultry and human samples in Bangladesh. This study was conducted to assess its pathogenic potentials and shedding probability in backyard chicken. Materials and methods: We infected 22 backyard chickens orally, each with 106 cfu of Salmonella Kentuckey, which were then observed for 23 days to enlist clinical signs, gross and histo-pathological changes. Polymerase chain reaction (PCR) for Salmonella was applied on some representative samples to identify the presence of Salmonella. Results: Four chickens were sacrificed and the internal organs were examined to observe gross and microscopic tissue changes. Some reactive changes were seen in spleen during prolonged course of infection. The probability of S. Kentucky shedding was 77% (95%; CI 54-90%) on DPI 2, 41% (95%; CI 21-60%) on DPI 12 and 13% (95%; CI 3-31%) on DPI 21. The survival probability of the infected chickens was 50% (95%; CI 28-68%) on DPI 6, 32% (95%; CI 14-51%) on DPI 15 and 14% (95%; CI 3-31%) on DPI 23. Conclusion: Zoonotic S. Kentucky strain of human non-typhoidal clinical cases of gastroenteritis has potentials to produce clinical signs such as reduced feed uptake, watery or pasty fecal droppings and lesions, such as catarrhal enteritis and typhlitis.

Objective: The research work was aimed at assessing the prevalence and risk factors of Peste-des-petits-ruminants (PPR) in goats in some selected areas of Bangladesh along with a comparison of different hemato-biochemical parameters of PPR infected goats. Materials and methods: A presumptive diagnosis of PPR was done based on clinical signs and symptoms. A structured record keeping sheet was used for the estimation of prevalence and risk factors of PPR in goat. A total of 103 blood samples were collected randomly and analyzed for hematobiochemical parameters using automated hemo-analyzer. Results: Out of 103 cases, Black Bengal (59%) and young goats aging minimum-12 months (43.85%) were recognized as highly susceptible to PPR disease. Strong association was found among all the three factors such as age, breed and sex (RR>1). All the values of hematological parameters such as TEC, TLC, Hb, PCV, and DLC were decreased in PPR affected goat as compared to healthy goats except lymphocyte counts, which was increased significantly (P=0.00). The amount of total protein (3.15 gm/L) and albumin (16.88 gm/L) were reduced drastically in PPR affected goats. Conclusion: The lymphocyte content in blood was significantly increased where as the total protein and albumin percent were decreased in the goats affected with PPR. Moreover, this variation in blood profile due to PPR virus infected in goat might be a good indicator in this disease diagnosis. [J Adv Vet Anim Res 2018; 5(2.000): 211-217]

Objective: The objective of this research was to study the histological structures of proventriculus by light and scanning electron microscope and to investigate the localization of glucagon immunoreactive cells within the turkey proventriculus. Materials and methods: Ten adult healthy turkeys were used in this study. The specimens were fixed in 10% buffered neutral formalin. The tissue samples were studied through routine histological and immunohistochemical techniques. Other samples were used for scanning microscope. Results: This study confirmed that the turkey proventriculus was formed from four tunics; tunica mucosa, tunica submucosa, tunica muscularis and tunica serosa. The lamina epithelialis was simple columnar and gave positive reaction in Periodic Acid Schiff (PAS) stain. The lamina propria contained simple tubular glands lined with columnar cells with lymphocyte infiltration. The submucosa contained proventricular glands formed with many round lobules. Each lobule was consisted of secretory tubules radiating from the central lumen of the lobule. The lining epithelium of the central lumen was columnar epithelium. The epithelium of the secretory tubules was cuboidal. Scanning electron microscopic observations showed the mucous membrane was consisted of many macroscopic papillae that formed from many folds which separated by furrows. Immunohistochemical observations revealed that glucagon immunoreactive cells were mainly determined inside the proventricular glands than within the surface epithelium mainly in the basal portion of the lobules and in the epithelium of central lumen of gland lobules. Conclusion: The structure of proventriculus structure in turkey has some variations as compared to other species of birds, and this may be attributed to the diet and its nutritious behavior.

Objective: Until recently, management of repeat breeding in cattle remains a major problem to dairy farmers. This study was carried out to improve the fertility in cows, those did not conceive after three or more consecutive services. Materials and methods: Twenty-three repeat breeding cows were selected from the Central Cattle Breeding Station and Dairy Farm (CCBS & DF), Savar, Dhaka, Bangladesh. Data of another 23 repeat breeding cows that conceived after four or more services were collected from the same farm as controls. The repeat breeders were synchronized for estrus with two injections of PGF2α 11 days apart and timed AI (TAI) was performed. Results: Seventeen of 23 cows had uterine infections. Intrauterine infusion of penicillin daily for three successive days from the following day of the first PGF2α injection resulted in 94.1% (16/17) recovery. Of 23 treated cows, four with estrus synchronization and TAI, and one with only AI after hormone treatment were detected pregnant by per rectal examination of the genital tract. By this pregnancy, the treated cows have advanced average of 131.6 days calving interval and days open, and thereby saved neat US $3,045.3 in comparison to control cows. Control group cows incurred losses of US $15,134.0 compared with average days open of the treated pregnant cows. Conclusion: Intrauterine infusion of penicillin can successfully recover the uterine infections, and estrus synchronization followed by TAI resulted in pregnancy in a proportion of repeat breeder cows with economic benefit that had a uterine infection.
