[Study on the biology feature and pathogenicities to silkworm of a microsporidium isolated from Barathra brassicae L].
A microsporidium (called as Bab-M) was isolated from Barathra brassicae L. captured from suburban vegetable plot of Guang Zhou. The spores were long-ovoid in shape and 4.02 +/- 0.36 microns x 1.99 +/- 0.36 microns in size. Immunologically the microsporidium shared spore surface specific antigen(s) with N. bombycis. The ultrastructure and life cycle of Bab-M were similar to that of N. b.. The rate of transovarian transmission was high. The initial conclusion was that Bab-M should be referred to as Nosema bombycis, but there was variation between them.
