Experimental Analysis of Interactions Among Saprotrophic Fungi from A Phosphorous-Poor Desert Oasis in the Chihuahuan Desert.

Fungal ecological interactions play a key role in structuring community assemblages. These associations may involve both antagonistic and synergistic relationships, which are commonly influenced by abiotic factors such as nutrient conditions. However, information for extreme, oligotrophic systems remain poor.

[Effectiveness of the implementation of clinical-epidemiological management during Covid-19 in a medium-long-stay hospital.].

Objective: The effects of the Covid-19 health emergency have demonstrated the high vulnerability of people residing in medium and long-stay centers, with high mortality rates. Little data is available about contingency protocols to minimize the spread of the virus in these centers. The goal of this study was to describe the clinical and epidemiological features of patients affected by SARS-CoV-2 and the preventive and management measures adopted at the National Hospital for Paraplegics (Toledo, Castilla-La Mancha, Spain) to minimize the risk of transmission of Covid-19.

Impact of treated wastewater for irrigation on soil microbial communities.

The use of treated wastewater (TWW) for irrigation has been suggested as an alternative to use of fresh water because of the increasing scarcity of fresh water in arid and semiarid regions of the world. However, significant barriers exist to widespread adoption due to some potential contaminants that may have adverse effects on soil quality and or public health. In this study, we investigated the abundance and diversity of bacterial communities and the presence of potential pathogenic bacterial sequences in TWW in comparison to synthetic fresh water (SFW) using pyrosequencing.

Multicenter study in Colombia: Impact of a multidimensional International Nosocomial Infection Control Consortium (INICC) approach on central line-associated bloodstream infection rates.

Background: The objective of this study was to analyze the impact of a multidimensional infection control approach and the use of the International Nosocomial Infection Control Consortium (INICC) Surveillance Online System on central line-associated bloodstream infection (CLABSI) rates from June 2003-April 2010.

Methods: We conducted a prospective, before-after surveillance study of 2,564 patients hospitalized in 4 adult intensive care units (ICUs) and 424 patients in 2 pediatric ICUs of 4 hospitals in 2 cities of Colombia. During baseline, we performed outcome surveillance of CLABSI applying the Centers for Disease Control and Prevention's National Healthcare Safety Network definitions.
