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 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 aim of this paper is to report surgical correction of ureteric rupture due to stenosis induced secondary to accidental injury by placing nephrovesical subcutaneous ureteric bypass in a dog and postoperative long term outcomes. Materials and methods: Imaging techniques revealed multiple bone fractures as well as left proximal ureter injury. The all bone fractures were corrected using standard techniques while left proximal ureter injury was treated as conservation medical therapy. One month later, contrast media were also found in proximal ureter and abdomen which indicated ureter rupture. This rupture was corrected surgically by nephrovesical subcutaneous ureteric bypass (SUB) under fluoroscopy guidance. Results: First day after accidental injury, the serum BUN and CRE were 10.7 mg/dL and 0.9 mg/dL, respectively which indicated kidney injury but by conservative therapy these parameters were lowered gradually. On the 5th day after considering these parameters, the dog was judged normal. However, on the 31st day BUN and CRE were 14.3 mg/dL and 0.8 mg/Kg, respectively. The Doppler ultrasonography revealed hydroneprosis, proximal ureter stenosis and high resistive index (0.72±0.02) in the renal arcuate artery indicating renal abnormalities due to ureter obstruction. On re-examination by radiography after one month postoperatively, revealed that patency of the device and normal renal function. The dog was clinically normal with normal urination and no complications were found 6 months postoperatively. Conclusion: In view of the above findings, it is suggested that the SUB system can be a better alternative to preserve the kidney in non-reparable traumatic ureteral damage in dogs.

Objective: This study assessed the applicability of loop-mediated isothermal amplification (LAMP) for the detection of leptospirosis among domesticated animals and sewage rats. Specifically, it evaluated the ability of LAMP to amplify Leptospira spp. targeting the 16s rRNA gene in boiled urine samples. Materials and methods: A total of 140 samples from different domestic animals were tested for the presence of the antigen. A nested-polymerase chain reaction (nPCR) protocol was used to compare and determine the sensitivity of LAMP in detecting Leptospira spp. The LAMP was also evaluated by comparing its amplification result using agarose gel electrophoresis and color change using dye. Results: Positivity rate of Leptospira spp. antigen was 29.0% (40/140) for LAMP and 9.3% (13/140) for nPCR. Also, LAMP results for gel electrophoresis and dye color change varied in some samples that may be due to the interpretation of the result in dye color change. Conclusion: Overall, LAMP is a rapid, sensitive, and cost-effective diagnostic method compared with nPCR. Also, LAMP has a potential application as pen-side screening, surveillance, and clinical diagnostic kits of infectious diseases without requiring advance equipment and skilled personnel.
