Latent Neoehrlichia mikurensis Infections May Be Reactivated in Patients With B‐Cell Lymphomas Treated With Rituximab

Immunology, Volume 178, Issue 2, Page 307-317, June 2026.
Eight percent of this cohort of patients had a latent Neoehrlichia mikurensis infection. It was only the latently infected patients who had N. mikurensis‐specific T cells, not the matched B‐cell lymphoma patients without the infection. The T‐cell responses of latently infected patients included perforin‐expressing Th1 and CD8+ T cells that upregulated ...

A Case of Sepsis Caused by ST80 Multidrug‐Resistant Enterococcus faecium With Concurrent Klebsiella pneumoniae Infection in a Dog

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
An 8‐year‐old dog developed acute respiratory distress that progressed to sepsis and death. Multidrug‐resistant Enterococcus faecium ST80 was isolated from the liver and kidney, while Klebsiella pneumoniae was detected in the lung by PCR. Whole‐genome sequencing showed that the ST80 isolates were genetically identical, suggesting hematogenous spread ...

Novel Magnetic Resonance Imaging Findings of Bilaterally Symmetrical Lesions in a Dog With Concomitant Granulomatous Meningoencephalitis and Necrotizing Encephalitis

Veterinary Radiology &Ultrasound, Volume 67, Issue 1, January 2026.
ABSTRACT A 3‐year‐old, female neutered Bichon Frise was presented with a 2‐day history of behavioral changes and ataxia. The neurological examination was consistent with diffuse forebrain involvement, with left lateralization. An MRI study identified bilaterally symmetrical T2W/T2 fluid‐attenuated inversion recovery (T2‐FLAIR) hyperintense, T1W ...
