Studies on mycoplasma infection of laying geese

Abstract
Infertile eggs, dead embryos and tissues from laying geese (airsacs, peritoneum, oviduct, ovary, ova) were examined for presence of myco‐plasmas. Forty‐three of 110 eggs and the birds laying mycoplasma‐containing eggs proved to be positive for mycoplasmas. One of the strains was used for experimental infection of laying geese. A reduction in egg production, an increased number of infertile eggs, egg transmission of mycoplasmas and loss of body weight of hatched goslings, were observed due to the mycoplasma infection.
