Asinamai Athliamai Bitrus | Rungtip Chuanchuen | Taradon Luangtongkum
Antimicrobial resistance as a result of emergence of extended-spectrum beta lactamase producing Enterobacteriaceae is a major health problem of human and animal that requires an intensive global attention. The production of beta lactamase enzymes remains as one of the major factors contributing to the development of resistance to beta lactams. These enzymes hydrolyze the beta lactam ring of the antibiotic and render it ineffective. Extended-spectrum beta lactamase producing bacteria have the ability to develop resistance to a number of antibiotics including the carbapenem and other third generation cephalosporins. In addition, the recent emergence and dissemination of the colistin resistance determinants mcr-1, mcr-2 and mcr-3 poses a serious threat to colistin as a drug of last resort in human medicine. In this review, we utilized words such as colistin resistance and Escherichia coli, Klebsiella and colistin resistance, colistin resistance and Salmonella as well as detection of mcr-1 genes in Salmonella and E. coli. The extended-spectrum beta lactamase producing bacteria under Enterobacteriaceae that are resistant to colistin possess the ability to be transferred resistant determinants to other susceptible cells at a higher frequency. In this paper, the role of manure from food animals and how air travel contributes to the dissemination of mcr-1 haboring bacteria, resistance determinants and other metabolites that constitute a public health problem was also reviewed. It is concluded that these pathogens have significant consequences to the control of infection and plays key roles in treatment failure with colistin. [J Adv Vet Anim Res 2018; 5(1.000): 1-11]

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]

Objective: Shiga-toxin producing Escherichia coli (STEC) is the most important foodborne bacterial pathogen worldwide and the bovine animals are assumed as a reservoir of this pathogen. The present study was conducted to assess the role of bovine animals as the source of STEC.Materials and methods: To assess the role of bovine animals as the source of STEC, we examined 100 samples (50 rectal swab and 50 beef samples) collected from the local beef slaughterhouses by cultural, morphological, biochemical tests and polymerase chain reaction. Finally, the drug resistance pattern of isolated organisms has been examined. Result: In the preliminary screening by polymerase chain reaction (PCR), E. coli was more prevalent in rectal swab (n=21/50) than beef samples (n=16/50). Among 39 isolated E. coli, 10 isolates were confirmed as STEC (Rectal swab=7, Beef=3) by PCR, where stx2 gene (n=7/10) was predominant than stx1 gene (n=3/10). Remaining 29 isolates did not react to stx primers in PCR. Presence of STEC in beef samples was significantly associated with the fecal contamination at P≤0.1 (0.074818) in Pearsons correlation coefficient method. In addition, most of the isolated STEC strains were resistant to one or more commonly used antimicrobials in the country. Conclusion: The bovine animals and its products could be an important source of multidrug-resistant STEC in the country. [J Adv Vet Anim Res 2018; 5(2.000): 218-225]

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.

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 present study was carried out to investigate the influence of weaning on the abnormal behavior, behavioral problems and some stress indicators in young rabbits. Materials and methods: The study was conducted on seventy two New Zealand rabbit kits which were divided into two groups, one reared with their dams (Unweaned rabbits) and the other group reared without their dams (Weaned rabbits). Rabbits are reared on traditional wire net batteries. A scan sample technique was used during the observation period of the recorded traits. Rabbits behavior was observed three times per day at (from 8.00 to 9.00 h.), (from 12.00 to 13.00 h) and (from 15.00 : 16.00 h) for three days weekly to each group during the experimental period (6 weeks). The observed activities were recorded at 10 min interval for rabbits in each subgroup (6 subgroups for each group). Two blood samplings were taken after weaning process for monitoring some stress indicators.Results: The results showed that the bare biting and lixite bite were significantly affected by weaning which were increased in the weaned group than the unweaned group. Other abnormal behavioral traits and behavioral problems were not influenced by weaning process. The results found that cortisol, growth hormone levels, superoxide dismutase and catalase enzyme activities were significantly increased in serum after weaning.Conclusion: The weaning process has negative effect on some behavioral and physiological responses. So, rearing the young rabbits with their mothers is advantageous from the viewpoint of animal welfare. The findings of this study may help to find out suitable strategies to minimize post weaning stress in both human beings and domestic animals. [J Adv Vet Anim Res 2018; 5(2.000): 166-172]

Objectives: This experiment was conducted on buffaloes to see effect of showering on maintaining good quality of buffalo semen in hot season.Materials and methods: This study was conducted on 6(six) indigenous buffalo bulls in hot summer of March and April 2017. The effect of multiple showering vs single shower alone on fresh and equilibrated semen quality was observed. The buffalos were divided into similar two groups (according to age and weight) and housed in half-walled openshed with adequate spacing and the feeding management being identical. The bulls in the control group were allowed to a single shower at 10.00 am and experimental bulls were allowed to four showers at 07.00, 10.00, 13.00 and 16.00. Temperature and humidity were recorded during this time. The average temperature was around 35°C along with 72% relative humidity. The quality of experimental bulls semen was evaluated in terms of volume, live sperm, sperm concentration, sperm motility, motion parameters and morphology for normal and abnormal sperm. For this analysis Computer Assisted Semen Analysis (CASA) system was used. Results: Between experimental group and control group semen quality differs significantly for volume (2.04±0.13 mL; 2.53±0.27 mL) (P [J Adv Vet Anim Res 2018; 5(1.000): 12-18]

Objective: The objective of this retrospective study was to evaluate the preoperative clinical characteristics to predict postoperative neurologic recovery in dogs with intervertebral herniated disk disease (IVDD). Materials and Methods: The dogs were classified according to postoperative neurologic recovery from clinical history of the hospital e-book. Excellent when dogs (n=13) were neurologically normal; good (n=8) when postoperative neurologic grade was improved from preoperative condition had improved sufficiently to require no or minor therapy after discharge; fair (n=4) is considered when postoperative neurologic status was unchanged from preoperative condition and poor (n=5) when major postoperative complication developed as a consequences neurologic grade had worsened at discharge than their preoperative score or the patient died. The evaluated preoperative clinical characteristics in all groups are breed, age, sex, duration of clinical sings appearance (DCSA), preoperative neurologic grading system (PNGS), compression rate (pre and post-operative) in MRI and CT scan, housefield unit (HU), type of IVDD and surgical procedures, and compared with excellent group. Results: no definitive relationship was found between the clinical characteristics and neurologic recovery, except, DCSA and preclinical neurologic pathological condition. The DCSA were 73.54±15.00, 117.63±31.58, 171.25±99.56 and 175.00±94.83 (P [J Adv Vet Anim Res 2018; 5(2.000): 240-246]
