Background: Spontaneous bacterial peritonitis is a serious complication in cirrhotic patients, and changes in the microbiological characteristics reported in the last years are impacting the choice of antibiotic used for treatment.
Objective: The aim of the present study is to evaluate the changes in the epidemiology and bacterial resistance of the germs causing spontaneous bacterial peritonitis over three different periods over 17 years.
Methods: All cirrhotic patients with spontaneous bacterial peritonitis and positive culture of ascites fluid were retrospectively studied in a reference Hospital in Southern Brazil. Three periods were ramdomly evaluated: 1997-1998, 2002-2003 and 2014-2015. The most frequent infecting organisms and the sensitivity in vitro to antibiotics were registered.
Results: In the first period (1997-1998) there were 33 cases, the most common were: E. coli in 13 (36.11%), Staphylococcus coagulase-negative in 6 (16.66%), K. pneumoniae in 5 (13.88%), S. aureus in 4 (11.11%) and S. faecalis in 3 (8.33%). In the second period (2002-2003), there were 43 cases, the most frequent were: Staphylococus coagulase-negative in 16 (35.55%), S. aureus in 8 (17.77%), E. coli in 7 (15.55%) and K. pneumoniae in 3 (6.66%). In the third period (2014-2015) there were 58 cases (seven with two bacteria), the most frequent were: E. coli in 15 (23.1%), S. viridans in 12 (18.5%), K. pneumoniae in 10 (15.4%) and E. faecium 5 (7.7%). No one was using antibiotic prophylaxis. Considering all staphylococci, the prevalence increased to rates of the order of 50% in the second period, with a reduction in the third period evaluated. Likewise, the prevalence of resistant E. coli increased, reaching 14%.
Conclusion: There was a modification of the bacterial population causing spontaneous bacterial peritonitis, with high frequency of gram-positive organisms, as well as an increase in the resistance to the traditionally recommended antibiotics. This study suggests a probable imminent inclusion of a drug against gram-positive organisms in the empiric treatment of spontaneous bacterial peritonitis.

Introduction-Aim: Spontaneous bacterial peritonitis (SBP) is a common complication in cirrhotic patients and is associated with a high mortality rate. The aim of this study is to determine the epidemiological and bacteriological profile of spontaneous bacterial peritonitis, as well as antibiotic resistance among hospitalized patients at CHU Mohammed VI, in order to guide empirical antibiotic choices for better management. Methods: This is a prospective study conducted over a period of 12 months, from January to December 2023, focusing on all requests for bacteriological examination of ascitic fluid samples.

Introduction: Despite treatment with antibiotic therapy, spontaneous bacterial peritonitis (SBP) accounts for approximately 20-40% mortality in hospitalized patients. The data is scarce regarding mortality predictors in SBP. Recently, multiple factors have been studied for effectiveness in prognosis prediction in SBP.

Diabetic wounds often exhibit a chronic non-healing state due to the combined effects of multiple factors, including hyperglycemia, impaired angiogenesis, immune dysfunction, bacterial infection, and excessive oxidative stress. Despite the availability of various therapeutic strategies, effectively managing the complex and prolonged healing process of diabetic infected wounds remains challenging. In this study, we combined the natural antidiabetic drug lipoic acid (LA) with the RADA16-YIGSR (RY) peptide obtained through solid-phase synthesis, utilizing reversible hydrogen bonds and coordination bonds for binding.

Microbes have been shown to adapt to stressful or even lethal conditions through displaying genome plasticity. However, how bacteria utilize the ability of genomic plasticity to deal with high antimony (Sb) stress has remained unclear. In this study, the spontaneous mutant strain SMAs-55 of sp.

A phage-antibiotic synergy could be an alternative in urinary tract infection (UTI) therapy, as it leads to the elimination of bacteria and to the reduction in variants resistant to phages and antibiotics. The aims of the in vitro study were to determine whether phages vB_Efa29212_2e and vB_Efa29212_3e interact synergistically with selected antibiotics in the treatment of infections, to optimize antibiotic concentrations and phage titers for the most effective combinations, and to assess their impact on the number of spontaneous resistant variants and on the phages' reproductive cycles. The modified double-layer disc diffusion method, checkboard, time-kill assays, one-step growth method and the double agar overlay plaque assay were implemented.
