Gastric Non-Helicobacter pylori Urease-Positive Staphylococcus epidermidis and Streptococcus salivarius Isolated from Humans Have Contrasting Effects on H. pylori-Associated Gastric Pathology and Host Immune Responses in a Murine Model of Gastric Cancer.

In populations with similar prevalence of Helicobacter pylori infection, cancer risk can vary dramatically. Changes in composition or structure of bacterial communities in the stomach, either at the time of exposure or over the course of H. pylori infection, may contribute to gastric pathology.

Detection of in Fur Swab and Fecal Samples by Using PCR Analysis.

Current methods for detecting mites in mouse colonies have limitations in terms of cost, accuracy, and throughput. To address these limitations, we developed PCR assays to detect in fecal samples. Using a newly generated ribosomal RNA sequence of (MC28S), we developed PCR and qPCR assays capable of detecting mites or eggs ingested during grooming.

Cutaneous Dermatophilosis in a Meadow Jumping Mouse ().

A laboratory-housed, wild-caught, subadult, male meadow jumping mouse (Zapus hudsonius) presented with extensive scaling of the face, limbs, and tail and severe edema of the paws. Postmortem examination revealed marked distal limb edema with focal digital hematomas and white scales, scabs, and crusts affecting the majority of nonhaired skin. Histopathologic analysis revealed severe, multifocal, chronic-active exudative and proliferative dermatitis characterized by multilaminated crusts covering the epidermis.
