Effects of microplastic concentration, composition, and size on biofilm-associated antimicrobial resistance.

Unlabelled: Microplastics (MPs) have emerged as a significant environmental pollutant with profound implications for public health, particularly as substrates to facilitate bacterial antimicrobial resistance (AMR). Recently, studies have shown that MPs may accommodate biofilm communities, chemical contaminants, and genetic material containing AMR genes. This study investigated the effects of MP concentration, composition, and size on the development of multidrug resistance in .

Impacts of Replacing Blended Fish Meal With Diverse Animal and Plant Protein Sources and Their Combinations in the Diets on Growth, Feed Availability, Biochemical Composition, and Blood Chemistry of Rockfish ().

The impacts of replacing diverse animal and plant protein sources, and their combination of fish meal (FM) on growth, feed consumption and utilization, biochemical composition, and blood chemistry of juvenile rockfish () were examined. One thousand and eighty juvenile (mean initial weight of 2.5 g) rockfish were assigned to 27 flow-through tanks with a capacity of 250 L each, with 40 fish per tank.

A step forward to revolutionize the eimeriosis controlling strategies in cattle by using traditional medication.

More than 10 species of Eimeria is found in cattle but Eimeria zuernii is one of the most pathogenic protozoan parasites affecting the global livestock industry. At the herd level, E. zuernii can cause illness in 10-80% of animals and reduce gross margins by 8-9%, leading to estimated annual losses of $731 million.

Understanding the impacts of temperature and precipitation on antimicrobial resistance in wastewater: theory, modeling, observation, and limitations.

Changing climate may contribute to increased antimicrobial resistance (AMR), particularly in wastewater which acts as a reservoir for resistant bacteria. Here, we determined how applying climate dependencies to our previously published model, rooted in theory, impacts computational simulations of AMR in wastewater. We found AMR levels were reduced at lower temperatures but increased with lower precipitation.
