Seroepidemiologic Study Designs for Determining SARS-COV-2 Transmission and Immunity

Emerging Infectious Diseases, 2020
Serologic studies are crucial for clarifying dynamics of the coronavirus disease pandemic. Past work on serologic studies (e.g., during influenza pandemics) has made relevant contributions, but specific conditions of the current situation require ...

Seroepidemiology of porcine toxoplasmosis: A cross‐sectional study in Bosnia and Herzegovina

Veterinary Medicine and Science, Volume 11, Issue 4, July 2025.
This study presents the first documentation of Toxoplasma gondii infection in animals in the Bosnia and Herzegovina. A total of 437 pigs from 87 farms were tested, showing 44.8% of farms and 13.3% of pigs positive for T. gondii, with significant associations found between seropositivity and farming practices.

Current Distribution of Selected Vector‐borne Diseases in Domestic Dogs From Bucharest, Romania

Veterinary Medicine and Science, Volume 11, Issue 4, July 2025.
Serological testing of 317 dogs in Bucharest (2020‐2024) revealed an overall Canine vector‐borne diseases (CVBD) seroprevalence of 8.8%, with Dirofilaria immitis (12.62%) being the most common. Shelter and older dogs had higher infection rates. Climate change and vector expansion may influence pathogen spread, underscoring the need for enhanced ...

Rapid Diagnostic Testing for Infective Endocarditis and Myocarditis Using Nanopore Targeted Sequencing

iLABMED, Volume 3, Issue 2, Page 191-200, June 2025.
This research presents a method based on nanopore targeted sequencing (NTS) with pathogen‐specific panels for testing infective endocarditis (IE) and myocarditis. The NTS achieved a detection limit of 20 copies/test for the IE target panel and 10 copies/test for the myocarditis target panel.

Serologic evidence of the exposure of small mammals to spotted-fever Rickettsia and Rickettsia bellii in Minas Gerais, Brazil

Journal of Infection in Developing Countries, 2016
Introduction: Sources of pathogenic Rickettsia in wildlife are largely unknown in Brazil. In this work, potential tick vectors and seroreactivity of small mammals against four spotted-fever group Rickettsia (R. rickettsii, R. parkeri, R.

Seroprevalence of Toxoplasmosis among Shelter-Housed Felines in a Philadelphia Suburb

Animals, 2022
Members of the Felidae family are the definitive host of the ubiquitous zoonotic parasite Toxoplasma gondii. Few studies have been conducted to determine the epidemiology of T. gondii in domestic felines within animal shelter populations.

Using the nonhuman primate model of HCMV to guide vaccine development. [PDF]

, 2014
The natural history of human cytomegalovirus (HCMV) is inextricably associated with mucosal surfaces. The vast preponderance of primary infections occur following mucosal exposure to infectious virions, and the high seroprevalence of HCMV throughout the ...

Preliminary Seroepidemiological Studies on the Human Syncytial Virus

Journal of General Virology, 1978
The seroepidemiology of the human syncytial virus was investigated by means of an indirect immunofluorescence test on 241 sera from Kenya, Tunisia, Singapore and Britain. These included sera from patients with nasopharyngeal carcinoma, other tumours of the oro-nasopharynx, tumours of other parts of the body, and from normal donors.

Seroepidemiologic studies on Babesia caballi and Babesia equi infections in Japan.

Journal of Veterinary Medical Science, 2002
Antibodies to Babesia caballi and Babesia equi were examined on a total of 2,019 horse serum samples that had been collected in 1971-1973 by the National Institute of Animal Health by enzyme-linked immunosorbent assay (ELISA) using recombinant proteins ...
