A 10-year-old spayed mongrel dog was referred with repeated intercurrent hematochezia and anal bleeding. The dog was vigorous and had a normal appetite, and the fecal test showed no abnormal signs. Despite treatment primarily with sulfasalazine, the condition did not improve and unilateral blindness developed. A Prototheca zopfii infection was identified by further examination with bowel cultur...
A new strain of Prototheca zopfii Krüger was grown on acetate or on pure n-alkanes. A maximum acetate-supported exponential growth of 12 divisions day occurred at pH 5 and 30 degrees C. At 25 degrees C, growth on n-alkanes was almost as fast, but no growth occurred at 30 degrees C. After 4 days at 25 degrees C, 34 to 45% of the n-alkanes had been removed, whereas at 21 degrees C and slower grow...
Prototheca zopfii infections are becoming global concerns in humans and animals. Bovine protothecal mastitis is characterized by deteriorating milk quality and quantity, thus imparting huge economic losses to dairy industry. Previous published studies mostly focused on the prevalence and characterization of P. zopfii from mastitis. However, the ultrastructural pathomorphological changes associa...
In this paper an outbreak of mastitis in cows resistant to antibiotic treatment on a Holstein-Friesian cattle farm in Vojvodina (Serbia and Montenegro) was described. Microbiological examination of 73 milk samples from lactating cows revealed the presence of Prototheca zopfii in 22 samples (30.13%). Identification of the isolates was performed on the basis of growth features, microscopic appear...
Growth of Chlorella vulgaris and Prototheca zopfii is inhibited by treatment with 3-amino-1,2,4-triazole. Growth of these 2 algae in the presence of amino triazole is accompanied by the accumulation in the culture media of the dephosphorylated histidine precursor, imidazoleglycerol. The addition of histidine to the culture media in the presence of amino triazole restored the normal growth rates...
