A comparison of two types of scalders was conducted to determine their effectiveness in reducing bacterial contamination of poultry carcasses. A conventional hot-water scalder and a prototype model of a steam scalder were tested under commercial conditions. Total plate counts from steam-scalded birds were significantly lower than the counts of water-scalded birds immediately after scalding and again after picking. No differences in the two methods could be found after chilling. Coliform counts from steam-scalded birds were significantly lower than the counts from water-scalded birds immediately after scalding. No significant differences in coliform counts were detected when the two scald methods were compared after defeathering and chilling.

Background And Objective: Periodontitis and dental caries are among the most prevalent oral diseases, with chronic periodontitis being a multifactorial, infectious condition that leads to inflammation in the supporting structures of the teeth, progressive attachment loss, and bone resorption. Chronic periodontitis is driven by a consortium of pathogenic microorganisms. This study aimed to evaluate the efficacy of virgin coconut oil (VCO) pulling in reducing the microbial load and inflammatory mediators responsible for chronic periodontitis, in comparison to chlorhexidine (CHX) mouthwash and distilled water.

Hyper immunoglobulin M (IgM) syndromes are a collection of uncommon primary combined immunodeficiency disorders. They are characterized by recurrent bacterial infections due to low levels of IgG, IgA, and IgE, while IgM levels remain normal or high. These conditions stem from a mutation in the CD40 ligand gene or disruptions in the CD40-signaling pathway.

With the aging population, the incidence of diabetes is increasing. Diabetes often leads to restricted neovascularization, antibiotic-resistant bacterial infections, reduced wound perfusion, and elevated reactive oxygen species, resulting in impaired microenvironments and prolonged wound healing. Hydrogels are important tissue engineering materials for wound healing, known for their high water content and good biocompatibility.
