Within hours of chick delivery, acute mortality and mucosal lesions were reported on 2 northeast Georgia broiler farms that had applied a ferric sulfate litter amendment product. Histological evaluation of the larynx, tongue, and surrounding stroma revealed multifocal areas of necrosis or degeneration of the oral mucosa, acute focal necrotizing cellulitis, and the presence of a brown-black pigmented material adhered to affected epithelial and mucosal surfaces. Multifocal to diffuse ventricular koilin degeneration and acute hemorrhage was also demonstrated in association with pigmented adherent material on affected surfaces. Perls iron stain revealed that adherent material on affected tissues was strongly positive for iron. An experiment was designed to reproduce clinical signs, lesions, and mortality using the same litter amendment product. The ferric sulfate litter amendment was confirmed as the causative agent.

The evolution of metastasis, the spread of cancer to distal sites within the body, represents a lethal stage of cancer progression. Yet, the evolutionary dynamics that shape the emergence of metastatic disease remain unresolved. Here, using single-cell lineage tracing data in combination with phylogenetic statistical methods, we show that the evolutionary trajectory of metastatic disease is littered with bursts of rapid molecular change as new cellular subpopulations appear, a pattern known as punctuational evolution.

The purpose of the current study was to investigate the potential ameliorating murine reproductive effects of herbal tea extracts against bisphenol A-induced (BPA) cytotoxicity. A comparative study was applied among red, green and blue teas in mice groups. Samples were coded as RTE, GTE and BTE groups, respectively.

Biological soil amendments of animal origin (BSAAO) are a source of foodborne pathogens that can contaminate fresh produce. This study evaluated the survival of E. coli over 140 d in agricultural soils amended with composted poultry litter (PL), heat-treated poultry pellets (HTPP), or unamended (UN) in Florida (FL) and Georgia (GA).

Bacterivorous nematodes are important grazers in the soil micro-food web. Their trophic regulation shapes the composition and ecosystem services of the soil microbiome, but the underlying population dynamics of bacteria and archaea are poorly understood. We followed soil respiration and 221 dominant bacterial and archaeal 16S rRNA gene amplicon sequencing variants (ASVs) in response to top-down control by a common bacterivorous soil nematode, Acrobeloides buetschlii, bottom-up control by maize litter amendment and their combination over 32 days.

Several amendments have been used to reduce ammonia (NH) emissions from broiler litter (BL); however, a comparative study between amendments and their application rates has not been fully explored. This study evaluated the potential of biochar (B), zeolite (Z), Flue Gas Desulphurization-Gypsum (FGD-G), and sodium bisulfate (S) at four application rates in reducing NH emissions from BL. The treatments comprised of amendment types (4) and their application rates (4), and a control with no amendment for a total of 17 treatments replicated twice and arranged in a completely randomized design.
