Mycoplasma synoviae (Ms) is considered to be an economically important poultry pathogen.
Although the full economic costs of infection in layer chickens are still under debate, the
prevalence of Ms is known to be high in some countries and earlier reports have shown a
correlation between infection and Eggshell Apex Abnormality (EAA). This work is a
continuation of an earlier study of a clinical case of EAA on a layer hen farm where the
presence of two different strains of Ms, based on the sequence of the 5′ end of the vlhA …
