American foulbrood BHL41835771

Description:

Description: PLATE VII Vegetative form, spore formation, spores, flagella, and giant whips of Bacillus larvae. Photomicrographs: A.— Vegetative form from a 24-hour culture on the surface of brood-filtrate agar, x 1000. B.— Spore formation and spores from the surface of brood-filtrate agar. X 800. C— Flagella. Stained by Loeffler's method as modified by Johnson and Mack. X 1000. (Retouched.) D.— Spores from a stained smear made directly from a decaying larva dead of American foulbrood. X 1000. E.— The production within the rods of separate elements, each being supplied with flagella. X 1000. F. — Giant whips and small spherical bodies in the older cultures of B. larvae obtained from the water of condensation of a brood-filtrate-agar slant culture. Fixed in 50 per cent formalin and stained with carbol fuchsim X 1000. G — Small and larger giant whips, and spherical bodies similar to those of F. X 1000. A similarity existing between the microscopic appearance of giant whips and spirochetes caused Maassen (14) to believe them to be spirochetes and to introduce the name Spirochaeta apis. H.— Very large whip, and spherical bodies similar to those of F and G. X 1000. Date:. Source: https://www.biodiversitylibrary.org/pageimage/41835771. Author: White, G. F. Page ID41835771.
