Bacillus coagulans (Weizmannia coagulans) is a lactic acid–forming bacterial species first isolated and described in 1915 by B.W. Hammer at the Iowa Agricultural Experiment Station as a cause of an outbreak of coagulation in evaporated milk packed by an Iowa condensary.[1] Separately isolated in 1935 and described as Lactobacillus sporogenes in the fifth edition of Bergey's Manual of Systematic Bacteriology, it exhibits characteristics typical of both genera Lactobacillus and Bacillus; its taxonomic position between the families Lactobacillaceae and Bacillaceae was often debated. However, in the seventh edition of Bergey's, it was finally transferred to the genus Bacillus. DNA-based technology was used in distinguishing between the two genera of bacteria, which are morphologically similar and possess similar physiological and biochemicalcharacteristics.[2][3]
Bacillus coagulans is a Gram-positive, catalase-positive, spore-forming, motile, facultative anaerobe rod that measures approximately 0.9 μm by 3.0 μm to 5.0 μm. It may appear Gram negative when entering the stationary phase of growth. The optimum temperature for growth is 50 °C (122 °F); range of temperatures tolerated are 30–55 °C (86–131 °F). IMViC tests VP and MR (methyl red) are positive.
This species has been recently transferred into the genus Weizmannia.[4]

Dermatophilus congolensis is a Gram-positive bacterium and the cause of a disease called dermatophilosis (sometimes called mud fever) in animals and humans, a dermatologic condition that manifests as the formation of crusty scabs containing the microorganism. It has been erroneously called mycotic dermatitis.[1] Rainscald is another condition often seen in animals, which is also caused by D. congolensis.
