BACKGROUND: Extended spectrum beta lactamases (ESBL) are responsible for increased resistance to third generation cephalosporins. Proteus species is an important cause of both community acquired and nosocomial infections. The Proteus spp is usually susceptible to beta lactam drugs but there is progressive increase in beta lactam resistance and recently ESBLs are also fast spreading to this species. OBJECTIVE: This study was conducted to study ESBL production and occurrence of TEM, SHV and CTX M beta lactamases in clinical isolates of Proteus spp in a tertiary care centre...

OBJECTIVE: The presence of resistant microorganisms is a major cause of failure in initial empirical antimicrobial therapy. The objectives of this study are to determine the resistance profile of microorganisms that cause bacteraemia of abdominal origin and to identify whether the previous use of antibiotics and the place of acquisition of bacteraemia are risk factors associated with the presence of resistant organisms. MATERIAL AND METHODS: A clinical, observational, epidemiological, retrospective cohort study was conducted with all the adult patients admitted to a university hospital from 2011-2013...

AIM: Neonatal sepsis remains an important cause of morbidity and mortality, and requires prompt empiric treatment. However, only a minority of babies who receive antibiotics for suspected sepsis have an infection. Antimicrobial exposure in infancy has important short- and long-term consequences. There is no consensus regarding empirical antimicrobial regimens. METHODS: The study included a survey of empiric antimicrobial regimens in all tertiary neonatal intensive care units in Australia and New Zealand in 2013-2014...

Hypothalamic tanycytes are specialized bipolar ependymal cells that line the floor of the third ventricle. Given their strategic location, tanycytes are believed to play several key functions including being a selective barrier and controlling the amount of hypothalamic-derived factors reaching the anterior pituitary. The in vitro culture of these cells has proved to be difficult. Here, we report an improved method for the generation of primary cultures of rat hypothalamic tanycytes. Ependymal cultures were derived from tissue dissected out of the median eminence region of 10-day-old rats and cultured in a chemically defined medium containing DMEM:F12, serum albumin, insulin, transferrin and the antibiotic gentamycin...

The present study investigated the clinical effect of antibiotic de-escalation therapy in elderly patients with chronic obstructive pulmonary disease (COPD) complicated with severe pneumonia. According to the parity method of hospitalization number, 86 cases were selected and divided into the observation and control group with 43 cases each. Based on empirical antibiotic application, levofloxacin and cephalosporin antibiotics were used in the control group. After treatment for 3 days, the regimen was adjusted to antibiotics active against Gram-positive (G+) and Gram-negative (G-) bacteria such as the third or fourth generation cephalosporin antibiotics, combined with aminoglycoside, or macrolide antibiotics according to their effects...

Drug resistance is a phenomenon where by an organism becomes fully or partially resistant to drugs or antibiotics being used against it. Antibiotic resistance poses an exacting intimidation for people with underlying medical immune conditions or weakened immune systems. Infections caused by the enzyme extended spectrum β-lactamase (ESBL) producing multi drug resistance (MDR) Enterobacteriaceae especially Escherichia coli and Klebsiella pneumoniae are resistant to a broad range of beta lactams, including third generation cephalosporins...

PROBLEM: Albert Einstein defines insanity as doing the same thing over again but expecting different results. Although the United States claims to reduce antibiotic abuse, practice strict isolation, and clean meticulously, the burden of Clostridium difficile outpaces goals. Unless innovative approaches are tried, we risk culling elderly, immunosuppressed, and otherwise debilitated populations. Emergency departments are a primary access point for patients who are unable to wait for primary care...

Antibiotics are routinely used in intensive animal agriculture operations collectively known as Concentrated Animal Feed Operations (CAFO) which include dairy, poultry and swine farms. Wastewater generated by CAFOs often contains low levels of antibiotics and is typically managed in an anaerobic lagoon. The objective of this research is to investigate the uptake and fate of aqueous sulfamethazine (SMN) antibiotic by alfalfa (Medicago sativa) grass grown under hydroponic conditions. Uptake studies were conducted using hydroponically grown alfalfa in a commercially available nutrient solution supplemented with 10mg/L of SMN antibiotic...

In order for veterinary surgeons to undertake an evidence-based approach to making decisions about their patients, it is important that new evidence is generated to support the clinical decision-making process. Many of the decisions are likely to be around the actions taken to treat or manage health problems discussed during the consultation, and little is currently known about the factors which affect the type of action taken. The aim of this study was to determine the decisions made and actions taken for health problems discussed during first-opinion small-animal consultations, as well as identifying factors which may affect the decision-making process...

BACKGROUND & OBJECTIVES: The emergence of multidrug-resistant Salmonella over the last two decades poses a major health risk. In this context, antimicrobial peptides have found a strategic place in the therapeutic armamentarium. Previously, we found that cryptdin-2 has the potential to augment the activity of conventional second- and third-generation anti-Salmonella antibiotics as evident by in vitro assays. In continuation to this, the present study was designed to evaluate the in vivo synergistic effects, if any, of cryptdin-2 in combination with ciprofloxacin and ceftriaxone against murine salmonellosis...

Morganella morganii is a rare cause of peritonitis in patients on peritoneal dialysis (PD). Most of the reported cases have resorted to a switch to hemodialysis. We herein report a case of peritonitis due to M. morganii resistant to third-generation cephalosporins, which was treated successfully with intraperitoneal (IP) tobramycin followed by oral ciprofloxacin. Early microbiologic diagnosis is essential in the treatment of peritonitis from rare microorganisms such as Morganella morganii, and appropriate antibiotic therapy is the key to avoiding catheter loss and subsequent switch to hemodialysis...

REVIEW
Stuart A Hill, Thao L Masters, Jenny Wachter
Etiology, transmission and protection: Neisseria gonorrhoeae (the gonococcus) is the etiological agent for the strictly human sexually transmitted disease gonorrhea. Infections lead to limited immunity, therefore individuals can become repeatedly infected. Pathology/symptomatology: Gonorrhea is generally a non-complicated mucosal infection with a pustular discharge. More severe sequellae include salpingitis and pelvic inflammatory disease which may lead to sterility and/or ectopic pregnancy. Occasionally, the organism can disseminate as a bloodstream infection...
