AI Article Synopsis

  • PCR amplification and colorimetric identification were utilized to detect DNA of Bartonella henselae and Afipia felis in patients suspected of cat scratch disease.
  • Six lymph node biopsies, along with blood and serum samples from 18 patients, were analyzed using specific probes and electrophoresis techniques.
  • The results indicated that PCR-DEIA is a sensitive and viable method for diagnosing cat scratch disease, with DNA from Bartonella henselae found in some patient samples.

Article Abstract

Polymerase chain reaction (PCR) amplification and colorimetric identification of amplicons were performed to detect Bartonella henselae and Afipia felis DNA in specimens from patients who were clinically and histologically suspected of having cat scratch disease. PCR products were revealed using 2% ethidium bromide agarose-gel electrophoresis and identified with specific probes in a commercial colorimetric hybridization assay (DEIA) (GEN-ETI-K; DiaSorin, Italy). Six paraffin-embedded lymph node biopsies from 18 patients as well as 18 samples of peripheral whole blood and 18 sera were investigated. Bartonella henselae DNA was recovered from the whole blood of four patients, and Bartonella henselae and Afipia felis DNA were detected in one patient's lymph node biopsy. This study suggests that PCR-DEIA is sufficiently sensitive to be considered feasible for the molecular diagnosis of cat scratch disease.

The Bartonella genus of bacteria encompasses ubiquitous species, some of which are pathogenic in humans and animals. Bartonella henselae, the causative agent of Cat Scratch disease, is responsible for a large portion of human Bartonella infections. These bacteria can grow outside of cells, replicate in erythrocytes and invade endothelial and monocytic cells.

Background: Fleas are insect vectors that transmit several Gram-negative bacterial pathogens acquired by ingesting infected vertebrate blood. To combat foodborne illness, insect midgut epithelial cells are armed with efficient microbial recognition and control systems, such as the immune deficiency (IMD) pathway that regulates the expression of antimicrobial peptides (AMPs). However, despite their medical and veterinary importance, relatively little is known about the IMD signaling pathway and production of AMPs in the digestive tract of cat fleas (Ctenocephalides felis).

Background: While metagenomic next-generation sequencing (mNGS) has been acknowledged as a valuable diagnostic tool for infections, its clinical validity and impact on patient management when using fresh tissue samples remains uncertain.

Methods: We conducted a retrospective cross-sectional study involving patients who underwent tissue mNGS at a tertiary hospital in China from February 2021 to February 2024, aiming to assess its ability to detect plausible pathogens and its clinical validity and impact.

Findings: A total of 520 mNGS results from 508 patients were analysed, detecting plausible pathogens in 302 (58.
