Prophylactic Antibiotics Ineffective Against Bloodstream Infections in ICUs Prophylactic Antibiotics Ineffective Against Bloodstream Infections in ICUs

In ventilated intensive care unit (ICU) patients, neither chlorhexidine (CHX) mouthwash nor selective oropharyngeal decontamination (SOD) nor selective digestive tract decontamination (SDD) seems to significantly reduce multidrug-resistant gram-negative bacteria (MDRGNB)-induced bloodstream infections in settings with moderate to high antibiotic resistance, researchers say.Reuters Health Information

Publication date: Available online 25 May 2019Source: Chemico-Biological InteractionsAuthor(s): Yingzhuan Zhan, Nan Ma, Rui Liu, Nan Wang, Tao Zhang, Langchong HeAbstractPolymyxin B (PMB) and polymyxin E (PME) are cyclic, peptide antibiotics which derived from various species of Paenibacillus (Bacillus) polymyxa. They are decapeptide antibiotics with an antimicrobial spectrum that includes Gram-negative bacteria, and reused as therapeutic agents due to the emergence of multidrug-resistant (MDR) Gram-positive bacteria. PMB or PME-induced anaphylactoid reactions in the clinic have been documented. However, the mechanism unde...

Conclusions: The strong association of infection with MDR organisms showing FQR with patient residence rather than with traditional risk factors suggests that the community environment is a major contributor to spread of these pathogens in children.

Levofloxacin is used for the treatment and prevention of multidrug-resistant tuberculosis in children, but current adult formulations are poorly palatable. A questionnaire administered to caregivers of 27 children taking a novel 100 mg dispersible taste-masked levofloxacin tablet found the new formulation to be more palatable (69%) and easier to prepare (81%) than the adult formulation. This formulation may assist children to better adhere to anti-tuberculous therapy.

CONCLUSIONS.: Salmonella Infantis has become one of the sero-varieties most frequently referred to the INS, which includes ESBLproducing multidrug-resistant strains with resistance to quinolones. Finally, the relevance of next generation sequencing is reasserted in the characterization of new variants of pathogens that are important for public health, and their potential use in antimicrobial resistance surveillance systems.

The widespread availability and use of modern synthetic therapeutic agents have led to a massive decline in ethnomedical therapies. However, these synthetic agents often possess toxicity leading to various adverse effects. For instance, anti-tubercular treatment (ATT) is toxic, lengthy, and severely impairs host immunity, resulting in posttreatment vulnerability to reinfection and reactivation of tuberculosis (TB). Incomplete ATT enhances the risk for the generation of multidrug- or extensively drug-resistant (MDR or XDR, respectively) variants of Mycobacterium tuberculosis (M. tb), the TB-causing microbe. Therefore, a new...

This study aimed to characterize the fecal colonization and sharing of Klebsiella pneumoniae strains between companion animals and humans living in close contact. Fecal samples were collected from 50 healthy participants (24 humans, 18 dogs, and 8 cats) belonging to 18 households. Samples were plated onto MacConkey agar (MCK) plates with and without cefotaxime or meropenem supplementation. Up to five K. pneumoniae colonies per participant were compared by pulsed-field gel electrophoresis (PFGE) after XbaI restriction. K. pneumoniae strains with unique pulse types from each participant were characterized for antimicrobial s...
