Prototheca zopfii Krüger Strain UMK-13 Growth on Acetate or n-Alkanes.

The metabolism of acetate in the colourless alga, Prototheca zopfii.

Diversity within the current algal species Prototheca zopfii: a proposal for two Prototheca zopfii genotypes and description of a novel species, Prototheca blaschkeae sp. nov.

In order to clarify the intraspecies taxonomic position of the non-photosynthetic algal species Prototheca zopfii, as well as the aetiology of bovine mammary protothecosis, a selection of P. zopfii strains isolated from clinical cases of protothecal mastitis and from various environmental habitats was characterized using a polyphasic molecular approach. Based on sequence analysis of the 18S rRN...

Nature of the Growth Factor for the Colorless Alga Prototheca Zopfii

Barker's study on the nutritive requirements of Prototheca zopfii indicated that this colorless alga fails to grow in the absence of small amounts of yeast extract. A study of the growth factor requirements of Prototheca has shown that the active constituent of yeast extract necessary for the growth of this organism is thiamin (vitamin B(1)). Thiamin can fully replace the complex yeast material...

Prototheca zopfii mastitis in a herd of dairy cows.

Mastitis caused by the colourless alga Prototheca zopfii was diagnosed in 17 of 120 cows in a dairy herd. Infection occurred in animals varying from 3-14 years old and was present in one to four quarters of each cow. Nine cases were associated with clinical mastitis characterised by the presence in milk of flakes or small clots. Somatic cell counts consistent with subclinical mastitis (>500 x 1...

Susceptibility of Prototheca zopfii strains isolated from cows with mastitis to chlorhexidine and iodine

* Correspondence: [email protected] Protothecosis is an infection reported in humans and in many other animal species caused by achlorophyllous algae of the genus Prototheca. These algae are primitive unicellular organisms considered to be chlorophylllacking mutants that have adopted a heterotrophic mode of nutrition. These organisms are widely disseminated in different environments...
