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]

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: This study was designed to determine the prevalence of bovine tuberculosis (bTB) at the municipal abattoir and cattle herds in peri-urban nomadic settlements of Bauchi state of Northeastern Nigeria. Materials and Methods: A total of 2440 cattle slaughtered at the municipal abattoir from June to September were examined for lesions characteristic of bTB and eighty-six (n=86) cows selected from two cattle herds located at temporary nomadic settlements in Bauchi metropolis were also screened for bTB using purified protein derivative (PPD) tuberculin skin test. During the study period, total of 2,440 cattle were slaughtered comprising majority of females (n=1656) and males (n=784) as well as of different breeds including majority of White Fulani (n=1864) followed by Red Bororo (n=508) and Sokoto Gudali (n=68). Results: The results revealed that out of the 2,440 slaughtered cattle inspected for tuberculous-like lesions, 51 had lesions suspected to be lesions characteristic of tuberculosis, while 48 were positive for Ziehl-Neelsen. Prevalence rate of 1.96% based on microscopic examination and 2.0% based on suspected gross lesion were recorded. The prevalence was 0.77% for males, 1.2% females, 1.84% for adults, 0.12% for calves and 1.8% for white Fulani (Bunaji), 0.12% for Red Bororo (Rahaji) and 0.04% for Sokoto Gudali (Bokoloji). In addition, screening of 86 cows showed that 8.1% were positive for tuberculosis using tuberculin test. Conclusion: The outcome of this study showed that bTB is still endemic in Bauchi state and this can pose a significant public health challenge. Thus, it is recommended that the government should intensify the test-and-slaughter policy as well as put in place an effective monitoring and surveillance control programs for bTB to mitigate the risks posed to public health by this zoonotic disease in the study area.

Objective: This study assessed personality traits in five cattle breeds (Bos taurus), two cosmopolitan (Holstein Friesian and Brown Swiss) and three endangered Italian autochthonous (Varzese, Rendena, and Modenese). Our aim was to provide an evaluation of the personality dimensions obtained by our questionnaire in order to compare some Italian autochthonous breeds with the cosmopolitan one. Our choice fell upon the comparison of the Varzese, the Modenese, the Rendena, the Brown Swiss, and the Holstein Friesian because the genetic selection at the base of the typical attitudes has induced different characteristics, and as a consequence, detectable differences in personality can be expected between the populations. Materials and methods: A personality questionnaire was completed by milkers/owners for each subject involved in this study. The milking staff involved in the study have been working with cows for over 20 years; they have experience with numerous breeds, and therefore, can be considered expert evaluators since they certainly have an appreciation of the full range of cow behavior. Results: The milkers assessments analysis found breed differences in dairy cattle, showing that certain personality traits are more marked in certain breeds in terms of curiosity, friendliness to milkers, and responses to unknown people. Conclusion: This pilot survey shows the usefulness of questionnaires in cattle personality studies, highlighting some peculiarity of the endangered breeds.

Objective: A retrospective survey was designed to determine the prevalence and factors involved in surgical cases at the Veterinary Teaching Hospital (VTH), Bangladesh Agricultural University from June 2014 to June 2017. Materials and materials: In total, 1042 surgical cases of food animal (large ruminants: n=564, and small ruminants: n=493) and 26 non-food animal (mono-gastric animal) were recorded from patient register book and case recording card. Data were analyzed by Epi Info TM software and frequencies were calculated for different variables using Statistical Package for Social Science (SPSS) software. Result: In large ruminant, hernia (16.13%) ranked top (90% umbilical and 10% lateral) followed by fracture (14.89%), abscess (14.54%), umbilical myasis (10.46%), atresia ani (5.85%) and naval ill (4.07%). Among the reported cattle, 87.41% were crossbred and 12.59% were indigenous. Calf, heifer and adult cattle were 55.32, 10.29 and 34.39% respectively. In small ruminants, castration (32.94%; n=138) ranked top followed by myasis (10.55%) naval ill (10.31%), abscess (7.44%), dystocia (6.24%) and urolithiasis (5.49%). Based on surgical classification in large and small ruminants, 37.56 and 42.50% were reported for general surgery, whereas 28.71 and 7.15% for congenital, 11.18 and 13.12% for gynecological and 2.65 and 37.23 % for andrological problems, respectively. Male and female ratio was 1:1.31 and 2:1 respectively in large and small ruminants, respectively. Conclusion: This study emphasizes the factors related to successful surgical cases management at VTH. The results may help in controlling surgical related cases in Mymensingh region of Bangladesh. [J Adv Vet Anim Res 2018; 5(1.000): 81-87]

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]

Objective: A cross sectional study was conducted in five Haor (wetland) districts of Bangladesh to investigate the epidemiological parameters and associated factors of recurrent outbreak of duck plague (DP) on the basis of molecular detection. Materials and methods: A total of 450 randomly selected duck farms containing 175,467 ducks were investigated for their morbidity, mortality and case fatality rates from December 2012 to November 2014. The farms were surveyed and the owners were interviewed using a prepared questionnaire about husbandry practice, disease history, bio-security measures, and flock and farmer details. A total of 150 samples (liver=50, intestine=50 and oro-pharyngeal tissue=50) were collected from duck plague suspected sick/dead ducks of north eastern part of Bangladesh during outbreak season. Samples were processed and PCR was done directly from the samples using primers specific for duck plague virus. Results: Out of 150 test samples of the fifty duck plague suspected ducks of fifty outbreaks, 90 samples (60%) of 36 ducks of thirty six outbreaks (72%) were found positive by PCR. Overall prevalence of duck plague was 8% at farm level and 3.30% at flock level. Morbidity, mortality and case fatality rates of duck plague at farm level were 52.08, 29.62 and 56.86%, respectively. Of the 22 variables selected for this study, 16 were found significant and the remaining 6 were found non-significant statistically. Conclusion: Results of the epidemiological investigation of the present study regarding duck mortality suggesting that education and training of the farmers on bio-security, modern husbandry practice, regular vaccination and innovation of cost effective intensive duck farming methods are necessary to control recurrent duck plague outbreak in Haor (wetland) areas.

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]

Objective: The present study was carried out for the isolation, identification and antibiogram study of Salmonella spp. from apparently healthy Japanese quails (Coturnix japonica) at three different quail farms in Mymensingh, Bangladesh. Materials and methods: A total of 75 cloacal swab samples were randomly collected from apparently healthy Japanese quails from three different farms at Mymensingh, Bangladesh. The samples were subjected to a series of cultural and biochemical examination for the isolation of Salmonella followed by molecular detection by polymerase chain reaction (PCR). Motility of the Salmonella was performed by motility test and amplification of speF gene. The antibiogram profile of the isolates was also evaluated against commonly used antimicrobials by disc diffusion method. Results: The overall prevalence of Salmonella spp. in quails was found to be 13.33%(n=10/75). Out of the 10 isolates, seven were found to be motile. Farmwise, the prevalence of Salmonella spp. were 10%(n=3/30), 24%(n=6/25) and 5%(n=1/20) at the quail farms of Bangladesh Agricultural University (BAU), Shikarikanda and Akua, respectively. The antibiogram study revealed that all the isolates were resistant to both Erythromycin and Tetracycline. On the other hand, 100% isolates were sensitive to both Ciprofloxacin and Imipenem. Ninety percent isolates of Salmonella were resistant to Colistin sulphate. Neomycin was found to be sensitive to 80% Salmonella isolates. All the Salmonella isolates were found to be multidrug resistant (MDR). Conclusion: The presence of MDR Salmonella spp. in quails signifies public health importance of the organisms, which may be associated with food-borne illness.
