Effects of hydroxybutyl chitosan on improving immunocompetence and antibacterial activities

This study demonstrated that HBCS could in turn lock moisture, can promote immunocompetence activity, can inhibit fibrosarcoma cell migration, and exhibits anti-bacterial functionality. Taken together, these results indicate that HBCS shows substantial promise for applications in cosmetics, biomedicine, and antibacterial therapies.

Authors: Fukushima K, Yanagisawa N, Sekiya N, Izumiya H Abstract Non-typhoidal Salmonella (NTS) infection is a major pathogen causing gastroenteritis among immunocompetent adults. NTS infection is mainly transmitted by contaminated food and water, but some cases are transmitted by animal contact. Salmonella enterica subsp. enterica serovar Poona (S. Poona) is an NTS usually transmitted by reptiles, and cases including outbreaks of gastroenteritis have been reported previously. However, invasive infections due to this organism among immunocompetent adults are rare. We herein report a case of a 39-year-old man who wa...

Epidemiology of β-Lactamase-Producing Staphylococci and Gram Negative Bacteria as Cause of Clinical Bovine Mastitis in Tunisia. Biomed Res Int. 2019;2019:2165316 Authors: Klibi A, Jouini A, Boubaker El Andolsi R, Kmiha S, Ben Hamda C, Ghedira K, Hamrouni S, Ghram A, Maaroufi A Abstract The aim of this study was to determine the species distribution of Staphylococcus, Gram negative bacteria (GNB) and the occurrence of Methicillin Resistant Staphylococci (MRS) and Extended-Spectrum β-lactamase- (ESBL-) producing GNB. Bacterial culture of 300 clinical mastitis milk samples from 30 different far...

Publication date: Available online 19 September 2019Source: Protein Expression and PurificationAuthor(s): Yi He, Yong Chen, Daniel L. Morris, Duck-Yeon Lee, Nico TjandraAbstractBax is a pro-apoptosis protein that translocates from the cytosol to the mitochondrial membrane upon initiation of programed cell death. Bax subsequently disrupts the mitochondria membrane, resulting in the release of cytochrome C which activates the downstream caspases. The structure of inactive Bax has been solved, but despite intensive investigation, the mechanism by which it regulates apoptosis is not established. The low yield of Bax expression...

In conclusion, turanose can attenuate colitis via regulatory effects on miRNA-21 expression and histone acetylation-related proinflammatory mediators. These findings also support further exploration of turanose as a potential therapeutic sugar substitute for patients with IBD.Graphical abstract

One way to re-sensitize MRSA to resistant antibiotics is by combining with approved non-antibiotics. The study was intended to explore susceptibility of MRSA to various antibiotics and non-antibiotics (NSAIDs) by micro dilution broth method. MRSA isolates were confirmed by PCR (mecA gene) and in-vitro antibiotic susceptibili...

ConclusionsIn conclusion, it would appear that the most prevalent mcr gene of E. coli from diarrheic weaned piglets in Korea was mcr-3. And, to our best knowledge, this is the first report for coexistence of two plasmid-mediated colistin resistance genes, mcr-1 and mcr-3 in the same isolates (0258, 0491, 0516) from piglets with diarrhea in Korea. Those mcr–positive isolates showed multi-drug resistance, and majority of those encoded Stx2e and F18. This indicates that the risk of inefficient treatment for edema disease in weaned piglets.

Conclusions: Healthy children with NTS musculoskeletal infections more frequently report reptile exposure and preceding gastrointestinal symptoms and have pelvic and spinal involvement compared with children with musculoskeletal infections due to S. aureus. NTS should be considered as a potential cause of musculoskeletal infections in children with these risk factors. In contrast to previous case reports and case series, children with NTS musculoskeletal infections had a low rate of complications.

From July 2009 to July 2015, Staphylococcus aureus isolated from pediatric sterile sites were selected. Polymerase chain reaction was used to detect mecA and lukS-PV/lukF-PV genes. The rate of methicillin-resistant Staphylococcus aureus was 37.7%. Ten isolates had the lukS-PV/lukF-PV genes, 2 of which were methicillin-resistant Staphylococcus aureus. Skin and soft tissues infections were significantly associated with lukS-PV/lukF-PV positive isolates, P = 0.008.

Conclusions: Among children with acute gastroenteritis who were younger than 5 years of age, L. reuteri compared with placebo, as an adjunct to rehydration therapy, did not reduce the duration of diarrhea; however, it reduced the duration of hospitalization.
