Introduction: Rickettsioses are zoonotic diseases transmitted by arthropods acting as vectors and reservoirs. Disease symptoms are nonspecific and, therefore, their clinical diagnosis is difficult. Indirect immunofluorescence (IFA) is the gold standard assay for diagnosis.

- This study investigated the prevalence of Human Pegivirus (HPgV) in Mexico among blood donors and HIV-infected individuals, revealing that 2.98% of blood donors and 33% of HIV patients tested positive for HPgV.
- Researchers analyzed nearly 8,000 serum samples using advanced PCR methods and found two prevalent HPgV genotypes, with viral loads showing distinct low and high patterns that affected HIV progression.
- The study concluded that high HPgV viremia may offer a beneficial effect on HIV infection markers, indicating the need for further exploration of the underlying mechanisms driving different HPgV replication patterns.
Rickettsioses caused by Rickettsia felis are an emergent global threat. Historically, the northern region of the province of Caldas in Colombia has reported murine typhus cases, and recently, serological studies confirmed high seroprevalence for both R. felis and R.
View Article and Find Full Text PDFRickettsia typhi and R. felis are the etiological agents of murine typhus and flea-borne spotted fever, respectively. Both are emerging acute febrile zoonotic diseases for which fleas are vectors; they also have similar clinical characteristics and global distribution.
