Chloramphenicol and several other antibiotics targeting bacterial ribosomes inhibit mitochondrial protein translation. Inhibition of mitochondrial protein synthesis leads to mitonuclear protein imbalance and reduced respiratory rates as confirmed here in HeLa and PC12 cells. Unexpectedly, respiration in INS-1E insulinoma cells and primary human islets was unaltered in the presence of chloramphenicol. Resting respiratory rates and glucose stimulated acceleration of respiration were also not lowered when a range of antibiotics including, thiamphenicol, streptomycin, gentamycin and doxycycline known to interfere with bacterial protein synthesis were tested...

BACKGROUND: Urinary tract infections (UTI) are a common medical problem affecting the general population and thus commonly encountered in medical practice, with the global burden of UTIs at about 150 million people. Because uropathogens largely originate from colonic flora, they are easy to predict, and this is the rationale for empirical treatment in Community Acquired-UTI (CA-UTIs). With the increasing prevalence of drug-resistant bacteria among adults with CA-UTI in Uganda, it is no longer adequate to manage CA-UTIs on empiric regimen without revising the susceptibility patterns of common CA-UTI causative agents...

Antibiotic resistance has been noted to be a major and increasing human health issue. Cold storage of raw milk promotes the thriving of psychrotrophic/psychrotolerant bacteria, which are well known for their ability to produce enzymes that are frequently heat stable. However, these bacteria also carry antibiotic resistance (AR) features. In places, where no cold chain facilities are available and despite existing recommendations numerous adulterants, including antibiotics, are added to raw milk. Previously, N2 gas flushing showed real potential for hindering bacterial growth in raw milk at a storage temperature ranging from 6 to 25°C...

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...

We present a colorimetric method for the detection of aminoglycoside antibiotics such as neomycin (NEO) using a reddish anionic dye, amaranth (AR(3-)). Under acidic conditions, at which NEO exists in fully protonated form (NEOH(6+)), the AR(3-) anion associates with the NEOH(6+) cation to form a precipitate, NEOH(AR)2. The precipitate was soluble in a buffer solution of pH 8.5, yielding a reddish solution with an absorption maximum at around 520 nm. Tobramycin and gentamycin, which exist as pentavalent cations under acidic conditions, gave almost the same results...

Lactobacilli are normal commensals of the gastrointestinal and female genital tract. Due to its low virulence these bacteria are known to cause opportunistic infections. They cause mostly bacteraemia with or without endocarditis and rarely cause pleuro-pulmonary infection. We report a case of Lactobacillus coryniformis pleuro-pulmonary infection and review 14 previously reported cases of lactobacilli causing pleuro-pulmonary infections. Our patient had small cell carcinoma with metastasis. All the 14 cases had pre-existing risk factors like immunosuppresion, cancer or chronic disease...

INTRODUCTION: Nocardia species usually cause opportunistic infections, and the frequency of these infections is increasing owing to the growing population of immunocompromised hosts. However, Nocardia species may sometimes cause an infection disease in immunocompetent hosts. Nocardia mexicana infections are the least common and are very rare. CASE PRESENTATION: Herein, we report the first case of a pulmonary infection with N. mexicana in a 61-year-old Japanese woman with a history of hyperlipidaemia and bronchiectasis and a 6-month history of non-productive hacking cough...
