Prototheca Zopfii? Mastitis in Holstein Dairy Herds and Its Characteristics of Insufficient Elimination from the Udder

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...

Identification of Prototheca zopfii from Bovine Mastitis

BACKGROUND The aim of this study was identification of the epidemiology of Prototheca zopfii species from the milk samples of dairy cattle in Isfahan, central Iran. METHODS Milk samples were obtained from 230 dairy cattle, 130 with and 100 without mastitis, in Isfahan. The samples were cultured in Prototheca Isolation Medium (PIM) and Sabouraud's dextrose agar. All P. zopfii isolates were ide...

Molecular characterization of Polish Prototheca zopfii mastitis isolates and first isolation of Prototheca blaschkeae in Poland.

Bovine mastitits caused by the colorless, yeast-like alga Prototheca zopfii is a serious and complex condition that results in heavy economic losses in the dairy industry, both through a substantial reduction in milk production and culling of infected animals. Based on the 18S rDNA sequence analysis, genotype-specific PCR assays have recently been developed to differentiate within the species P...
