Molecular mechanism for Tn7-like transposon recruitment by a type I-B CRISPR effector.

Tn7-like transposons have co-opted CRISPR-Cas systems to facilitate the movement of their own DNA. These CRISPR-associated transposons (CASTs) are promising tools for programmable gene knockin. A key feature of CASTs is their ability to recruit Tn7-like transposons to nuclease-deficient CRISPR effectors.

Los teléfonos móviles como potencial vehículo de infección en un entorno hospitalario.

ResumenEl objetivo de este artículo es investigar el posible papel desempeñado por los teléfonos móviles como depósitos de colonización bacteriana y los factores de riesgo que ésta conlleva en un ambiente hospitalario. Entre enero de 2013 y marzo de 2014 examinamos a 226 miembros del personal de un hospital regional de Australia (146 médicos y 80 estudiantes de medicina). Los principales resultados de interés se relacionaron con los tipos de microorganismos y la cantidad de contaminación encontrados en los teléfonos móviles.

Biodegradation of Synthetic Dyes of Textile Effluent by Microorganisms: An Environmentally and Economically Sustainable Approach.

Due to its overall environmental impact, the residual dye in the wastewater from the synthetic dye manufacturing and textile industries is a global concern. The discharge contains a high content of pigments and other additives, possessing complex structures. As per the requirement for dyed clothing, dyestuff in the effluent is less susceptible to acids, bases, and oxygen.

Determination of Antimicrobial Activity of Some Commercial Fruit (Apple, Papaya, Lemon and Strawberry) Against Bacteria Causing Urinary Tract Infection.

Urinary Tract Infection (UTI) is a worldwide phenomenon in modern times, in which the dependency on antibiotics for its treatment is increasing. The current study was conducted in order to find alternatives to antibiotics by investigating some commercial fruits for their antimicrobial activity. The fruits in this study included green apple (), papaya (), lemon (), and strawberry (), which were used to prepare methanolic and ethanolic extracts through Soxhlet extraction technique.

Isolation and identification of halotolerant soil bacteria from coastal Patenga area.

Objective: Halotolerant bacteria have multiple uses viz. fermentation with lesser sterility control and industrial production of bioplastics. Moreover, it may increase the crop productivity of coastal saline lands in Bangladesh by transferring the salt tolerant genes into the plants.

Mobile Phones as a Potential Vehicle of Infection in a Hospital Setting.

The objective of this article is to investigate the potential role of mobile phones as a reservoir for bacterial colonization and the risk factors for bacterial colonization in a hospital setting. We screened 226 staff members at a regional Australian hospital (146 doctors and 80 medical students) between January 2013 and March 2014. The main outcomes of interest were the types of microorganisms and the amount of contamination of the mobile phones.
