Inhibition of EV71 replication by an interferon-stimulated gene product L3HYPDH.

Enterovirus 71 (EV71) is the common causative agent of hand-foot-mouth disease (HFMD). Despite evidence in mice model suggested that the interferon (IFN) signaling pathways play a role in defending against this virus, knowledge on the IFN-mediated antiviral response is still limited. Here we identified an IFN-stimulated gene (ISG) called L3HYPDH, whose expression inhibits EV71 replication.

Meropenem Pharmacokinetics and Target Attainment in Critically Ill Patients.

Purpose: This study aimed to investigate the pharmacokinetics and target attainment of meropenem and compare the effect of meropenem dosing regimens in critically ill patients.

Patients And Methods: Thirty-seven critically ill patients who were administered meropenem in intensive care units were analyzed. Patients were classified according to their renal function.

Type I Interferon-Induced TMEM106A Blocks Attachment of EV-A71 Virus by Interacting With the Membrane Protein SCARB2.

Enterovirus A71 (EV-A71) and Coxsackievirus A16 (CV-A16) are the main causative agents of hand, foot and mouth disease (HFMD) worldwide. Studies showed that EV-A71 and CV-A16 antagonize the interferon (IFN) signaling pathway; however, how IFN controls this viral infection is largely unknown. Here, we identified an IFN-stimulated gene, (, encoding a protein that blocks EV-A71 and CV-A16 infection.

Safety evaluation study of lincomycin and spectinomycin hydrochloride intramuscular injection in chickens.

This study aimed to investigate the nonclinical safety of lincomycin and spectinomycin hydrochloride (LC-SPH) intramuscular (i.m) doses on target animals (chickens) to provide guidelines for dose level design and side effect monitoring in clinical trials. A total of 80 healthy Arbor Acres plus broiler chicks were completely randomized and blindly divided into four treatment groups (control, one-time dose, three-time dose, and five-time dose) of 20 chicks each (20 chickens per group).

Two Phenotype-Differentiated Mutants That Survived in a Meropenem Selection Display Large Differences in Their Transcription Profiles.

37662RM1 and 37662RM2 are two phenotypically different, carbapenem-resistant mutants of 37662 isolate following selection with meropenem (MEM) at sub-inhibitory concentrations. 37662RM2 lacks capsule synthesis and shows dramatically increased biofilm formation, while 37662RM1 shows merely impaired capsule synthesis. Here we report that 37662RM1 and RM2 have transcription profiles that are different from those of their starting strain, 37662WT.

Efficacy of enteric-coated tilmicosin granules in pigs artificially infected with Actinobacillus pleuropneumoniae serotype 2.

Background: Porcine infectious pleuropneumonia caused by Actinobacillus pleuropneumoniae (App) is one of the most serious infectious diseases in pigs and has brought huge economic losses to the world pig industry. The aim of this trial was to evaluate the effect of enteric-coated tilmicosin granule in the treatment and control of artificial infection of App.

Methods: Sixty Duroc and Yorkshire crossbred pigs (50 of which were artificially infected) were divided into six groups: BCG (Blank control group), ICG (Infection-only control group), HDG (High-dose enteric-coated tilmicosin granules), MDG (Medium-dose enteric-coated tilmicosin granules), LDG (Low-dose enteric-coated tilmicosin granules) and TPG (Tilmicosin premix drug control group).

Spiramycin and azithromycin, safe for administration to children, exert antiviral activity against enterovirus A71 in vitro and in vivo.

Hand-foot-mouth disease (HFMD) is a common viral disease in young children, mainly caused by enterovirus A71 (EV-A71) and coxsackievirus A16 (CV-A16). Specific antiviral agents are not commercially available yet. Here we report that the macrolide antibiotics spiramycin (SPM) and azithromycin (AZM) possess antiviral activities against EV-A71 and CV-A16.

Meropenem selection induced overproduction of the intrinsic carbapenemase as well as phenotype divergence in Acinetobacter baumannii.

Acinetobacter baumannii 37662 is a carbapenem-susceptible isolate with bla as the sole carbapenemase gene. Following selection with meropenem (MEM) at a subinhibitory concentration, two morphologically different mutants, designated 37662RM1 and 37662RM2, were obtained and characterised. Compared with the parent strain, resistant mutant 37662RM1 grew at a slower rate and had impaired capsule synthesis, whereas 37662RM2 grew fast and abolished capsule synthesis.

"Roar" of blaNDM-1 and "silence" of blaOXA-58 co-exist in Acinetobacter pittii.

Acinetobacter pittii 44551 was recovered from a patient with gout combined with tuberculosis and was found to harbor the carbapenemase genes blaNDM-1 and blaOXA-58 on two different plasmids pNDM-44551 and pOXA58-44551, respectively. pNDM-44551 displayed high self-transferability across multiple bacterial species, while pOXA58-44551 was likely co-transferable with pNDM-44551 into A. baumannii receipts.
