Activity of propyl-propane-thiosulfinate and propyl-propane-thiosulfonate against carbapenem-resistant Gram-negative bacteria.

Organosulfur compounds derived from plants of the Allium genus, such as propyl-propane-thiosulfinate (PTS) and propyl-propane-thiosulfonate (PTSO), have been proposed as an alternative in antibiotic resistance. The aim of this study was to compare the activity of these substances with other antibiotics against clinical isolates of carbapenem-resistant (CAR-R) and carbapenem-susceptible (CAR-S) Gram-negative bacteria. A total of 126 clinical isolates of CAR-R and 155 CAR-S bacteria were selected, including Enterobacterales, A.

Seropositivity Interacts with Catechol--methyltransferase Val105/158Met Variation Increasing the Risk of Schizophrenia.

Schizophrenia is a heterogeneous and severe psychotic disorder. Epidemiological findings have suggested that the exposure to infectious agents such as Toxoplasma gondii (T. gondii) is associated with an increased risk for schizophrenia.

[Sociodemographic characteristics and risk factors associated to significative bacteriuria in a Spanish health area].

Objective: To determine the epidemiological characteristics of significative bacteriuria (SB) and their relationship with sociodemographic factors and to analyze risk factors in inpatients.

Methods: Cross-sectional descriptive study carried out on urine culture samples received between 2016-2020 in the Microbiology laboratory, differentiating between minors and adults. The dependent variable was the presence of SB and the independent variables were age, sex, year, type of sample and source of the sample.

Antimicrobial Activity of the Circular Bacteriocin AS-48 against Clinical Multidrug-Resistant .

The treatment and hospital-spread-control of methicillin-resistant (MRSA) is an important challenge since these bacteria are involved in a considerable number of nosocomial infections that are difficult to treat and produce prolonged hospitalization, thus also increasing the risk of death. In fact, MRSA strains are frequently resistant to all β-lactam antibiotics, and co-resistances with other drugs such as macrolides, aminoglycosides, and lincosamides are usually reported, limiting the therapeutical options. To this must be added that the ability of these bacteria to form biofilms on hospital surfaces and devices confer high antibiotic resistance and favors horizontal gene transfer of genetic-resistant mobile elements, the spreading of infections, and relapses.

[Etiology of urinary tract infections in our health area and susceptibility profile of the most common uropathogens.].

Adequate empirical treatment should be established for treatment urinary tract infections, considering the prevalence of the most frequent microorganisms in each geographic area and their susceptibility to different antibiotics. The objective of the study is to analyze the epidemiology of UTIs in our Health Area as well as to understand the antibiotic susceptibility of the most prevalent isolated microorganisms to guide empirical treatment. The objective was to establish a reasoned system for recommending ITU empirical therapy, based on the microorganisms causing episodes assisted in a Regional Hospital, knowing their antibiotic susceptibility.
