Recurrence of CDI after successful treatment with antibiotics is high, thus necessitating discovery of novel therapeutics against this enteric pathogen. Administration of the secondary bile acid ursodeoxycholic acid (UDCA; ursodiol) inhibits the life cycles of various strains of C. difficile in vitro , suggesting that the FDA-approved formulation of UDCA, known as ursodiol, may be able to restore colonization resistance against C. difficile in vivo .}, number={6}, journal={INFECTION AND IMMUNITY}, author={Winston, Jenessa A. and Rivera, Alissa J. and Cai, Jingwei and Thanissery, Rajani and Montgomery, Stephanie A. and Patterson, Andrew D. and Theriot, Casey M.}, year={2020}, month={May} } @article{manning_birkenheuer_briley_montgomery_harris_vanone_gookin_2016, title={Intermittent At-Home Suctioning of Esophageal Content for Prevention of Recurrent Aspiration Pneumonia in 4 Dogs with Megaesophagus}, volume={30}, ISSN={["1939-1676"]}, DOI={10.1111/jvim.14527}, abstractNote={Background Megaesophagus carries a poor to guarded prognosis due to death from aspiration pneumonia. Options for medical management of regurgitation are limited to strategic oral or gastrostomy tube feeding. Objectives To describe the use and efficacy of intermittent esophageal suctioning to prevent regurgitation and associated episodes of aspiration pneumonia in dogs with megaesophagus. Animals Four dogs with acquired idiopathic megaesophagus and recurrent aspiration pneumonia. Methods Retrospective review of medical records of dogs with megaesophagus in which intermittent suctioning of esophageal content was employed for management of recurrent aspiration pneumonia. Results Intermittent suctioning of the esophagus was initiated in 4 dogs after failure of strict gastrostomy tube feeding failed to prevent regurgitation and repeated episodes of aspiration pneumonia. Suctioning was accomplished by esophagostomy tube in 3 dogs and per os in 1 dog. After initiation of esophageal suctioning, dogs survived for a median of 13.5 additional months (range, 10–30 months) during which time 2 dogs had no additional episodes of aspiration pneumonia and 2 dogs had infrequent episodes of pneumonia, but aspiration was suspected to be a contributing factor in their death. Complications included clogging of the esophagostomy tube, esophagostomy site infections, and esophagitis. Conclusions and Clinical Importance Use of intermittent esophageal suctioning in dogs with megaesophagus that continue to regurgitate despite gastrostomy tube feedings can reduce or abolish clinical episodes of aspiration pneumonia.}, number={5}, journal={JOURNAL OF VETERINARY INTERNAL MEDICINE}, author={Manning, K. and Birkenheuer, A.

Macrophages constitute the major inflammatory infiltrates in musculoskeletal tissues during these infections. However, the precise macrophage effector functions that affect the pathogenesis of arthritogenic alphaviruses have not been defined. We hypothesized that the severe damage to musculoskeletal tissues observed in RRV- or CHIKV-infected mice would promote a wound-healing response characterized by M2-like macrophages. Indeed, we found that RRV- and CHIKV-induced musculoskeletal inflammatory lesions, and macrophages present in these lesions, have a unique gene-expression pattern characterized by high expression of arginase 1 and Ym1/Chi3l3 in the absence of FIZZ1/Relmα that is consistent with an M2-like activation phenotype. Strikingly, mice specifically deleted for arginase 1 in neutrophils and macrophages had dramatically reduced viral loads and improved pathology in musculoskeletal tissues at late times post-RRV infection. These findings indicate that arthritogenic alphavirus infection drives a unique myeloid cell activation program in inflamed musculoskeletal tissues that inhibits virus clearance and impedes disease resolution in an arginase 1-dependent manner.}, number={8}, journal={JOURNAL OF IMMUNOLOGY}, author={Stoermer, Kristina A. and Burrack, Adam and Oko, Lauren and Montgomery, Stephanie A. and Borst, Luke B. and Gill, Ronald G. and Morrison, Thomas E.}, year={2012}, month={Oct}, pages={4047–4059} } @article{morrison_oko_montgomery_whitmore_lotstein_gunn_elmore_heise_2011, title={A mouse model of chikungunya virus-induced musculoskeletal inflammatory disease evidence of arthritis, tenosynovitis, myositis, and persistence}, volume={178}, number={1}, journal={American Journal of Pathology}, author={Morrison, T.
