Probiotics for Livestock – Reducing Antibiotic Reliance

In the wake of the Obama administration’s plan to decrease antibiotic usage in livestock, farmers are now trying to find alternatives that have fewer ecological and human health impacts. In an effort to reduce reliance on antibiotics, researchers at Iowa State University are testing if Lactobacillus species found in yogurt might have a similar health effect on livestock as …

Bacterial Diversity in Greater Mexico City Air

A paper from this past year by García-Mena et al entitled “Airborne Bacterial Diversity from the Low Atmosphere of Greater Mexico City” uses culture techniques and 16S sequencing of the air in Greater Mexico City. There doesn’t seem to be as much literature on microbes in the air as there is about other surfaces and parts of …

Arthropod Diversity in Urban and Suburban Homes

A paper from Bertone et al studies indoor arthropod diversity in urban and suburban homes. They surveyed all the arthropods they could find in 50 homes in North Carolina, finding 24-128 distinct arthropod families per home! These critters were filtering in from the outdoor surroundings of the home, and most of them were benign to humans. They also found …

Antibiotic Resistance in the News

Here are some recent news and science articles on antibiotic resistance that I found this afternoon: Some not so happy stories – Intestinal microbiome is related to lifetime antibiotic use in Finnish pre-school children Antimicrobial resistance a challenge to public health: Nadda Some happy/cool stories – Audiocast: Developing new antimicrobial drugs and alternatives Bills would prohibit livestock …

Blueprinting a New Antimicrobial

This recent news article discusses a new candidate antimicrobial called Globomycin and the work that researchers at  Trinity College Dublin have put in to map out its spatial organization. A particularly interesting point that is discussed is the idea of narrow-spectrum antibiotics. Antibiotic/antimicrobial resistance is driven in part by the fact that these drugs target a …

Antibiotic Resistance in Small-Scale Poultry Farming in Ecuador

mSphere, ASM’s new open access journal, published a paper recently called Antibiotic Resistance in Animal and Environmental Samples Associated with Small-Scale Poultry Farming in Northwestern Ecuador, written by Braykov et al. The abstract is as follows: The effects of animal agriculture on the spread of antibiotic resistance (AR) are cross-cutting and thus require a multidisciplinary perspective. …

Opportunistic Fungal Pathogens in Dishwashers and Kitchens

An interesting new paper titled The Black Yeast Exophiala dermatitidis and Other Selected Opportunistic Human Fungal Pathogens Spread from Dishwashers to Kitchens came out several days ago in PLoS one. Zupančič et al investigated the fungal diversity and distribution of 30 dishwashers. Swabs were taken from various parts in the dishwasher, sink, and on items that had been washed …
