Prevalence of Anti‐Leptospira Antibodies in Bovines (2018–2023) and Reported Serovars and Serogroups—A Systematic Review With Meta‐Analysis

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
A high global prevalence of anti‐Leptospira antibodies in cattle and buffaloes (39.5%) was identified, highlighting the widespread distribution of the bacterium and the need for increased attention to bovine leptospirosis. The prevalence of anti‐Leptospira antibodies was higher on dual‐purpose farms, but there were no significant differences between ...

Torque teno virus as a marker of immune status in immunocompromised patients: A systematic review

European Journal of Clinical Investigation, Volume 55, Issue 8, August 2025.
Abstract Background Torque teno virus (TTV) is not known to cause disease in humans; however, chronic inflammatory conditions and immunosuppression states can favour TTV replication. This study aimed to verify the effectiveness of TTV as an immune biomarker.

Long‐Term Humoral Immune Response After West Nile Virus Convalescence in Horses in a Geographic Area of Multiple Orthoflavivirus Co‐Circulation

Journal of Veterinary Internal Medicine, Volume 39, Issue 4, July/August 2025.
ABSTRACT Background In the last three decades, West Nile virus (WNV, Flaviviridae, Orthoflavivirus genus) has become one of the most important encephalitic agents worldwide, causing substantial numbers of cases in humans and horses every year by re‐emerging in endemic areas and emerging in new territories.

Serology as an early diagnostic tool in pediatric patients with Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome: a post hoc analysis of a phase 2 clinical trial

Journal of Clinical Microbiology
The specific anti-O polysaccharide antibody response in Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome (STEC-HUS) patients and its relevance for early diagnosis have not been previously studied in detail.

The multiple roles of the NlpC_P60 peptidase family in mycobacteria – an underexplored target for antimicrobial drug discovery

FEBS Letters, Volume 599, Issue 9, Page 1203-1221, May 2025.
The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Serodiagnosis of cryptococcosis.

Japanese Journal of Medical Mycology, 1985
わが国において, クリプトコックス症の血清学的診断法を普及する目的で, 抗原検出法として抗体感作ラテックス凝集反応 (LAテスト) を,抗体検出法として加熱菌体を用いたスライド凝集反応 (CSAテスト) を検討した. 当教室に検査依頼のあった34例のうち25例は医師により診断がつけられていたもので, そのうち13例はクリプトコックス髄膜炎, 9例は肺クリプトコックス症, 3例は皮膚クリプトコックス症であった. 9例は診断が未確定であった. LAテストに用いた感作ラテックス粒子の Cryptococcus neoformans A型株の多糖類抗原に対する最小抗原検出濃度は 2.4～9.8ng/mlであった.

Evidence of SARS‐CoV‐2 Exposure in Cats and Dogs From Households in Romania and Long‐Term Specific Seroconversion in Cats

Veterinary Medicine and Science, Volume 11, Issue 3, May 2025.
This study in Romania investigated SARS‐CoV‐2 antibodies in pets potentially exposed to infected owners during the COVID‐19 pandemic (2020–2022). The findings suggest that cats are more susceptible to SARS‐CoV‐2 infection than dogs, describe the long term persistence of antibodies in one cat, and asses the poor diagnostic value of a commercial ELISA ...
