AI Article Synopsis

  • The study focused on determining the seroprevalence of various Leptospira strains in cattle from Uganda, specifically in Kole and Mbale districts.
  • A total of 275 bovine serum samples from 130 smallholder farms were tested, revealing an overall seroprevalence of 19.27%, with the highest rates for the Pomona strain.
  • Results indicate past exposure to leptospires in the cattle population, with no significant differences observed based on district or gender.

Article Abstract

Seroprevalence of spp. in cattle is unknown in Uganda. The aim of this study was to estimate the seroprevalence of Icterohaemorrhagiae, Pomona, Butembo, Grippotyphosa, Nigeria, Hardjo, Wolfii, and Kenya and an overall seroprevalence in cattle from Kole and Mbale districts. Two hundred-seventy five bovine sera from 130 small holder farms from Kole ( = 159) and Mbale ( = 116), collected between January and July 2015, were tested for antibodies against eight strains by Microscopic Agglutination Test. A titer of ≥100 was considered seropositive, indicating past exposure. Overall, the seroprevalence was 19.27% (95% CI 14.9-24.5%). Pomona seroprevalence was highest with 9.45% (6.4-13.7%), followed by Kenya 5.09% (2.9-8.6%), Nigeria 4.00% (2.1-7.2%), Wolfii 3.27% (1.6-6.3%), Butembo 1.86% (0.7-4.4%), Hardjo 1.45% (0.5-3.9%), and Icterohaemorragiae and Grippotyphosa with less than 1% positive. Seroprevalence did not differ between districts and gender ( ≥ 0.05). Seven animals had titers ≥400. Cross-reactions or exposure to ≥1 serovar was measured in 43% of serum samples. Seroprevalence of 19% implies exposure of cattle to leptospires.

Introduction: One of the main causes of primary hepatocellular carcinoma and chronic hepatitis is the hepatitis C virus (HCV), with significant variability in its genotypes affecting pathogenicity and treatment outcomes. In India, prevalence ranges from 0.5 to 1.

An incursion and outbreak of Japanese encephalitis virus (JEV) was reported in Australia in 2021 and 2022, respectively. There was speculation that JEV may have been circulating in Australia unknowingly prior to the detection. In this study, we determined sero-prevalence and transmission of West Nile virus (WNV), Murray Valley encephalitis virus (MVEV) and JEV, prior to and post JEV incursion in a sentinel equine population in south-east Queensland (SEQ), Australia, using blocking ELISAs (screening test) and virus neutralisation test (confirmatory).

Bartonella is a vector-borne zoonotic pathogen, which could also be transmitted directly and cause a variety of clinical illnesses. This study aimed to investigate the prevalence of Bartonella in countries in the WHO Eastern Mediterranean Region (WHO-EMR) region. We searched using the keywords Bartonella and the name of each country in the WHO-EMR in databases such as PubMed, ISI (Web of Science), Scopus, and Google Scholar, with a publication date range of 1990-2022 and limited to English articles.
