Chlamydial Antibiotic Resistance and Treatment Failure in Veterinary and Human Medicine

Borel, Nicole, Leonard, Cory, Slade, Jessica, Schoborg, Robert V. 01 March 2016 (has links)
The Chlamydiaceae are widespread pathogens of both humans and animals. Chlamydia trachomatis infection causes blinding trachoma and reproductive complications in humans. Chlamydia pneumoniae causes human respiratory tract infections and atypical pneumonia. Chlamydia suis infection is associated with conjunctivitis, diarrhea, and failure to gain weight in domestic swine. Chlamydial infections in humans and domesticated animals are generally controlled by antibiotic treatment—particularly macrolides (usually azithromycin) and tetracyclines (tetracycline and doxycycline). Tetracycline-containing feed has also been used to limit infections and promote growth in livestock populations, although its use has decreased because of growing concerns about antimicrobial resistance development. Because Sandoz and Rockey published an elegant review of chlamydial anti-microbial resistance in 2010, we will review the following: (i) antibiotic resistance in C. suis, (ii) recent evidence for acquired resistance in human chlamydial infections, and (iii) recent non-genetic mechanisms of antibiotic resistance that may contribute to treatment failure.

Oxalobacter Formigenes Gen. Nov., Sp. Nov.: Oxalate-Degrading Anaerobes That Inhabit the Gastrointestinal Tract

Allison, Milton J., Dawson, Karl A., Mayberry, William R., Foss, John G. 01 February 1985 (has links)
This report describes a new group of anaerobic bacteria that degrade oxalic acid. The new genus and species, Oxalobacter formigenes, are inhabitants of the rumen and also of the large bowel of man and other animals where their actions in destruction of oxalic acid may be of considerable importance to the host. Isolates from the rumen of a sheep, the cecum of a pig, and from human feces were all similar Gram-negative, obligately anaerobic rods, but differences between isolates in cellular fatty acid composition and in serologic reaction were noted. Measurements made with type strain OxB indicated that 1 mol of protons was consumed per mol of oxalate degraded to produce approximately 1 mol of CO2 and 0.9 mol of formate. Substances that replaced oxalate as a growth substrate were not found.

A Systems Medicine Approach to the Role of Vitamins in Protecting the Gastrointestinal Tract From Oxidative Stress

Stone, Bill, Palau, Victoria, Krishnan, Koyamangalath 01 January 2017 (has links)
This chapter focuses on the role of antioxidant vitamins in protecting the gastrointestinal (GI) tract from oxidative stress. A systems medicine approach is used since it alone is sufficiently comprehensive to capture the broad range of relevant complexities and interrelationships relevant to GI protection. Systems medicine utilizes and integrates the vast amount of information gained from genomics and metagenomics, as well as environmental factors, and applies this information to better patient care. A major goal of system medicine is to develop paradigms to treat or slow the progression of chronic diseases, that is, disease prevention. GI disorders are quintessential examples of chronic inflammation with its attendant oxidative stress. Genomics and metagenomics have provided great insight into the underlying molecular mechanisms for GI disorders and will eventually help define individualized diets to minimize chronic inflammation. While the role of antioxidant nutrients and micronutrients is promising, there is a need for large-scale well-designed clinical trials supported by studies using animal models.

Revisión crítica: Beneficios de las intervenciones no farmacológicas para mejorar la motilidad intestinal en pacientes sometidas a cirugías ginecológicas abdominales en el periodo postoperatorio

Herrera Perez, Mayra Yaselit January 2020 (has links)
La cesárea es una de las intervenciones quirúrgicas abdominales más significativas, sin embargo, estudios revelan que la goma de mascar, alimentación temprana y la movilización acortan la duración de la estancia hospitalaria. El objetivo de esta investigación es conocer los beneficios de las intervenciones no farmacológicas para mejorarles la motilidad intestinal. La metodología que se utilizó Enfermería basada en la evidencia (EBE); elaborándose la pregunta clínica, con el esquema PICOT ¿Las intervenciones no farmacológicas: uso de goma de mascar, hidratación temprana y movilización precoz son beneficiosas para mejorar la motilidad intestinal en pacientes sometidas a cirugías ginecológicas abdominales en el periodo postoperatorio? realizándose búsqueda de evidencias en base de datos: Pubmed, Medline, Scielo, google académico Science Direct, Scielo, PubMed, se recopiló 50 artículos, seleccionándose por antigüedad, idiomas, entre otros criterios, quedando seleccionados 10 a los cuales se aplicó la guía de utilidad y Validez Aparente de Gálvez A, eligiéndose un artículo que se analizó con el programa de lectura crítica CONSOT; respondiendo a la pregunta que se planteó que las intervenciones no farmacológicas mencionadas en dicha pregunta minimizan complicaciones como distención abdominal, íleo paralítico, disminuyendo estancia hospitalaria y disminución de la carga de trabajo de las enfermeras, el nivel de evidencia 2 +, y según GRADE, el grado de recomendación es Alto.

Studies of gastric aspirate nitrite, pH, bacterial flora and mutagenicity in man

Coldrey, Norman A 31 March 2017 (has links)
Gastric aspirate specimens were collected from patients w~th clinically diagnosed gastric carcinoma and from non-carcinoma patients. The nitrite concentration and pH values of the aspirates were measured, the microorganisms present in selected specimens were isolated and identified, and the mutagenicity ratios of the aspirates were determined. The median nitrite concentration of the gastric aspirates from the carcinoma patients was significantly higher than that obtained for the non-carcinoma patients. A positive correlation was found between the nitrite concentration and the pH values of all the specimens tested, and a marked increase in nitrite levels at pH values above 6,0 was evident in specimens from the coloured ethnic "normal" subgroup. Gastric aspirate nitrite concentrations did not correlate with salivary values. The presence of microorganisms in gastric aspirates was shown to be pH dependent. Gastric aspirates with a pH < 2,0 were sterile, below pH 4,0 only acidophilic bacteria survived, whereas above pH 4,0, numerous species, predominantly members of the oral microflora, were isolated. The mean mutagenicity ratio of the gastric aspirates from the carcinoma patients was found to be significantly higher than that found for the control group. There was a positive correlation between the mutagenicity ratios of all the gastric specimens and pH with a maximum at a pH value of approximately 6,0.
