Exploring the relationship between polio type 2 serum neutralizing antibodies and intestinal immunity using data from two randomized controlled trials of new bOPV-IPV immunization schedules.

Inactivated polio vaccine (IPV) is now the only source of routine type 2 protection. The relationship, if any, between vaccine-induced type 2 humoral and intestinal immunity is poorly understood.

Randomized phase 2 therapeutic equivalence study of abiraterone acetate fine particle formulation vs. originator abiraterone acetate in patients with metastatic castration-resistant prostate cancer: The STAAR study.

This multicenter, randomized, open-label, active-controlled study evaluated therapeutic equivalence, steady-state pharmacokinetics, and safety of a novel abiraterone acetate fine particle formulation (AAFP) 500mg plus methylprednisolone vs. the originator AA (OAA) 1000mg plus prednisone in men with metastatic castrate-resistant prostate cancer (mCRPC). The primary endpoint was a comparison of aver...

Cryptococcosis manifesting as isolated biliary infection: Case report and brief review of literature.

Biliary cryptococci infection is rare, which is frequently diagnosed by exploratory laparotomy, preoperative diagnosis is difficult.

Prevalence of Pediculus capitis in schoolchildren in Battambang, Cambodia.

Pediculus capitis is the most common human ectoparasite. When it feeds on the blood through the scalp of its host, the anticoagulant in its saliva causes scalp inflammation and itching, and consequent scratching by the host causes further inflammation from bacterial infection. P. capitis infestation is currently a common parasitic dermatosis and a critical public health concern in underdeveloped ...

Emergence of polymyxin B resistance in a polymyxin B-susceptible KPC-producing Klebsiella pneumoniae causing bloodstream infection in a neutropenic patient during polymyxin B therapy.

The emergence of resistance to polymyxins in KPC-producing Klebsiella pneumoniae isolates has been a major clinical problem. This study evaluated the molecular mechanisms associated with polymyxin B (PMB) resistance that emerged in a previously PMB-susceptible KPC-2-producing K. pneumoniae during PMB therapy for a bloodstream infection in a neutropenic patient. The first isolate (PMB-susceptible) ...

CHROMagar mSuperCARBA and RAPIDEC® Carba NP test for detection of carbapenemase-producing Enterobacteriaceae.

A novel chromogenic medium CHROMagar mSuperCARBA was evaluated to detect carbapenem-resistant Gram-negatives. This medium is as sensitive and as specific as the SUPERCARBA medium for detecting KPC, MBL and OXA-48-type producers (100% and 100%, respectively) and is compatible with subsequent testing of carbapenemase activity using the RAPIDEC(®) CARBA NP.

Occurrence of Enterobacter hormaechei carrying blaNDM-1 and blaKPC-2 in China.

Three carbapenem-resistant clinical isolates of the Enterobacter cloacae complex (ECC) were recovered from different patients in a hospital. All 3 isolates carried 2 carbapenemase genes blaKPC-2 and blaNDM-1. A study was performed to characterize their relatedness and to investigate possible links among the patients. Whole genome sequencing revealed that the isolates were Enterobacter hormaechei a...

Enhanced antibacterial effects of green synthesized ZnO NPs using Aristolochia indica against Multi-drug resistant bacterial pathogens from Diabetic Foot Ulcer.

Increased incidence of Multi-drug resistance in microorganisms has become the greatest challenge in the treatment of Diabetic Foot Ulcer (DFU) and urges the need of a new antimicrobial agent. In this study, we determined the bactericidal effects of ZnO nanoparticles (ZnO NPs) green synthesized from Aristolochia indica against Multi-drug Resistant Organisms (MDROs) isolated from pus samples of DFU ...

Characterization of Vibrio parahaemolyticus and Vibrio vulnificus Recovered from Oysters during an Oyster Relay Study.

Vibrio parahaemolyticus (Vp) and Vibrio vulnificus (Vv) are naturally occurring estuarine bacteria and are the leading causes of seafood-associated infections and mortality in the USA. Though multiple-antibiotic resistant Vp and Vv have been reported resistance patterns in vibrios are not as well documented as other food-borne bacterial pathogens. Salinity relaying (SR) is a Post-Harvest Processin...

High prevalence and genetic diversity of large phiCD211/phiCDIF1296T-like prophages in Clostridioides difficile.

Clostridioides difficile (formerly Clostridium difficile) is a pathogenic bacterium displaying great genetic diversity. A significant proportion of this diversity is due to the presence of integrated prophages. Here, we provide an in-depth analysis of phiCD211, also known as phiCDIF1296T, the largest phage identified in C. difficile so far, with a genome of 131-kbp. It shares morphological and gen...

Influence of Enzalutamide on Cabazitaxel Pharmacokinetics; a Drug-Drug Interaction Study in Metastatic Castration Resistant Prostate Cancer (mCRPC) Patients.

In ongoing clinical research on metastatic castration-resistant prostate cancer (mCRPC) treatment, the potential enhanced efficacy of the combination of taxanes with AR-targeted agents, i.e. enzalutamide and abiraterone, is currently being explored. Since enzalutamide induces the CYP3A4 enzyme and taxanes are metabolized by this enzyme, a potential drug-drug interaction needs to be investigated.

Amplifying IFN-γ Signaling in Dendritic Cells by CD11c-Specific Loss of SOCS1 Increases Innate Immunity to Infection while Decreasing Adaptive Immunity.

Although prophylactic vaccines provide protective humoral immunity against infectious agents, vaccines that elicit potent CD8 T cell responses are valuable tools to shape and drive cellular immunity against cancer and intracellular infection. In particular, IFN-γ-polarized cytotoxic CD8 T cell immunity is considered optimal for protective immunity against intracellular Ags. Suppressor of cytokine...

A guard-killer phage cocktail effectively lyses the host and inhibits the development of phage-resistant strains of Escherichia coli.

In recent years, after the emergence of a large number of multidrug-resistant bacteria, phages and phage-associated products for the prevention and control of bacterial disease have revealed prominent advantages as compared with antibiotics. However, bacteria are susceptible to becoming phage-resistant, thus severely limiting the application of phage therapy. In this study, Escherichia coli cells ...
