Continuous infusion of amikacin, cotrimoxazole and carbenicillin was the second empirically established combination of antibiotics used when fever occurred during the induction phase of chemotherapy in sixty-five patients (58 acute myeloid leukemias, 5 acute lymphoid leukemias, 2 non Hodgkin lymphomas). Clinical evidence of infection was available in 25 cases and the infection was bacteriologically documented in 19 cases. Therapy was successful in 57 patients (89%). When infection was clinically or bacteriologically documented tha success rates were 92 and 82% respectively. The average length of treatment was ten days. In 25 patients receiving 2 g of amikacin in continuous infusion, the mean serum concentration was 15,9 micrograms/ml; in 17 patients receiving 3 g, the mean serum concentration was 19,4 micrograms/ml.

Multicellularity spans a wide gamut in terms of complexity, from simple clonal clusters of cells to large-scale organisms composed of differentiated cells and tissues. While recent experiments have demonstrated that simple forms of multicellularity can readily evolve in response to different selective pressures, it is unknown if continued exposure to those same selective pressures will result in the evolution of increased multicellular complexity. We use mathematical models to consider the adaptive trajectories of unicellular organisms exposed to periodic bouts of abiotic stress, such as drought or antibiotics.

is an understudied, gram-negative, aerobic bacterium that is widespread in the environment and increasingly a cause of opportunistic infections. Treating remains difficult, leading to an increase in disease severity and higher hospitalization rates in people with cystic fibrosis, cancer, and other immunocompromised health conditions. The lack of effective antibiotics has led to renewed interest in phage therapy; however, there remains a great need for well-characterized phages, especially against .

Fungal peritonitis is an uncommon but serious complication that can occur in patients undergoing peritoneal dialysis. It represents a small percentage of all peritonitis cases in these patients. Its diagnosis can be challenging due to the slow growth of fungi and frequent negative culture results.

() is a Gram-positive bacterium commonly colonizing the skin and mucosa in healthy individuals and hospitalized patients. Traditionally regarded as a contaminant, is now increasingly recognized as a potential cause of clinical infections, especially after the coronavirus disease pandemic. It has emerged as a pathogen implicated in severe infections, including pneumonia, bacteremia, meningitis, artificial joint infections, abdominal infections, and endocarditis.
