Population Structure and Molecular Epidemiology of Campylobacter coli Isolates of Porcine Origin from Different Geographic Regions and Production Systems

The genotypic diversity of C. coli isolates recovered from pigs from different geographic regions and production systems were investigated by multilocus sequence typing (MLST) method. A total of 99 C. coli isolates, 50 from Ohio and 49 from Wisconsin, representing the different production systems (conventional and antibiotic free) and resistance patterns (pan-susceptible, EryTet+ and others) were analyzed. Fifty different sequence types (ST) were identified by sequencing the seven housekeeping genes (aspA, ginA. gltA, glyA,pgm, tkt, and uncA). Seven of them were new STs (ST-3813, 3814,3815,3816, 3817, 3818 and 3819) identified for the first time. Of these, three resulted from new allele sequence at tkt and uncA loci and the remaining resulted from new combinations of the previously described alleles

Evaluation of intra-abdominal pressure in horses that crib

Objective: To measure intra-abdominal pressure (IAP) in horses that crib and compare it with IAP in horses that do not have this vice. Study Design: Cohort study. Animals: Healthy cribbing horses (cribbing cohort, n=8) and 8 healthy noncribbing horses (noncribbing cohort). Methods: A microsensor catheter was introduced into the peritoneal cavity through the right paralumbar fossa, using local anesthesia, for measurement of IAP. These pressures were recorded in 1-minute intervals for 2hours, while the horses were standing tied in a stall. IAPs of cribbing horses were compared to the noncribbing cohort. Results: Baseline IAPs were not significantly different between cribbing and noncribbing cohorts (P=.076); however, IAPs in the cribbing cohort were significantly increased when compared with the noncribbing cohort, during active cribbing behavior (P=.0016). Frequency of cribbing was not associated with increased IAP (P=.35). IAPs in the cribbing cohort remained significantly elevated compared with the noncribbing cohort, even after the behavior had ceased (P=.0002). Conclusion: Cribbing is associated with increased IAP in the horse, both during and after the behavior. © 2013 by The American College of Veterinary Surgeons
