Pet Birds

Hepatitis E virus (HEV), the causative agent of hepatitis E, has been reported in a wide variety of animals, including birds, but little is known of HEV infection in pet birds in northwest China. The objective of the present investigation was to examine HEV seroprevalence in three species of pet birds, namely, Eurasian siskin, Oriental skylark, and black-tailed grosbeak from Gansu. Serum samples collected from 685 pet birds from August 2011 to September 2012 were examined independently for the presence of antibodies against HEV. A total of 59 (8.31%) pet birds were tested positive for HEV antibodies by the commercially available enzyme immunoassay kits. Of these, the seroprevalence was diverse in different species pet birds; the most frequent level was 10.83% (39/360) in Eurasian siskin, followed by 6.57% (19/289) in Oriental skylark, and 2.29% (1/36) in black-tailed grosbeak. Age and collecting region of pet birds were the main risk factors associated with HEV infection. The present study firstly revealed the seroprevalence of HEV infection in three species of pet birds in northwest China, which provided the baseline data for taking comprehensive countermeasures and measures for effectively preventing and controlling HEV infection in birds.

Hepatitis E virus (HEV) infection is a major public health concern in low-income countries, yet incidence and prevalence estimates are often lacking. Serum (n = 653) and faecal (n = 150) samples were collected from apparently healthy individuals using convenience sampling technique in six communities (Ore, Oke-Osun, Osogbo, Ede, Esa-Odo, and Iperindo) from Osun State, Nigeria. Serum samples were analysed for total anti-HEV IgG/IgM and anti-HEV IgM using commercially available HEV ELISA kits. Total anti-HEV positive serum and all stool samples were analysed for HEV RNA by RT-PCR. Overall, 15.0% (n = 98/653) and 3.8% (n = 25/653) of the serum samples were positive for anti-HEV total and IgM antibodies, respectively. Total anti-HEV and IgM in Ore, Oke-Osun, Osogbo, Ede, Esa-Odo, and Iperindo was 21.0% (n = 13/62) and 3.2% (n = 2/62), 19.4% (n = 20/103) and 6.8% (n = 7/103), 11.4% (n = 12/105) and 2.9% (n = 3/105), 8.0% (n = 16/199) and 1.5% (n = 3/199), 22.0% (n = 22/100) and 10.0% (n = 10/100), and 17.9% (n = 15/84) and 0.0% (n = 0/84), respectively. All samples (stool and serum) were HEV RNA negative. Anti-HEV seroprevalence was associated with rural location, increasing age, alcohol consumption, and rearing of animals. This study demonstrated a high anti-HEV seroprevalence in Osun State, indicating the need to implement surveillance and asses the hepatitis E burden in Nigeria.

: Infectious hepatitis can be caused by Hepatitis A and Hepatitis E viruses. Hepatitis E infection is a water-borne disease transmitted by faeco-oral route. It is a cause of major health problems in developing countries. Outbreaks can happen due to improper hygiene and poor sanitation. Hepatitis E infection shows similar mode of transmission and clinical features of Hepatitis A infection. : This study was conducted to investigate the occurrence of Hepatitis E virus infection in patients screened for hepatitis A virus.: This prospective surveillance study was conducted between March 2020 to March 2021 on 57 serum samples which is came for the screening of anti-Hepatitis A virus IgM by enhanced Chemiluminescence method. These samples were collected and tested for anti- Hepatitis E virus IgM by Enzyme linked immunosorbent assay.: Among 57 samples, 11 samples (19.3%) were positive for Hepatitis A Virus IgM, 13 samples (22.8%) were positive for Hepatitis E virus IgM, and 7 samples (12.3%) were positive for both.: Hepatitis E virus infections were more than Hepatitis A virus. Hepatitis E and Hepatitis A virus co- infection was also observed. Screening of both viruses is suggested for infectious hepatitis.
