In order to characterize the humoral and cellular immune responses to bovine mammary protothecosis, serum and whey samples obtained from 72 dairy cows assigned to four different clinical stages of infection were examined for specific antibodies by indirect enzyme-linked immunosorbent assay techniques. Milk samples were analyzed for the total numbers of excreted algal cells and somatic cells. Af...
Prototheca species are achlorophyllous algae ubiquitous in nature and known to cause localized and systemic infection both in humans and animals. Although identification of the Prototheca species in clinical specimens is a challenge, there are an increasing number of cases in which molecular techniques have successfully been used for diagnosis of protothecosis. In this study, we characterized n...
Prototheca wickerhamii, an environmental alga, rarely causes human infections. We present a case of Prototheca wickerhamii cutaneous and systemic infections in an 85-year-old male with adrenal insufficiency. This organism was identified by morphological features and microbiological tests. The patient was successfully treated with ketoconazole.
A fragment of the Helicosporidium sp. (Chlorophyta: Trebouxiophyceae) plastid genome has been sequenced. The genome architecture was compared to that of both a non-photosynthetic relative (Prototheca wickerhamii) and a photosynthetic relative (Chlorella vulgaris). Comparative genomic analysis indicated that Helicosporidium and Prototheca are closely related genera. The analyses also revealed th...
Biopsy of a wound infection of the palmar fascia in a young diabetic woman revealed characteristic periodic acid-Schiff-positive Prototheca species cells with a rosette configuration and internal septation. Prototheca wickerhamii was cultured repeatedly from the wound drainage and the biopsy tissue. Several diagnostic features distinguishing Prototheca species, saprophytic algae, from yeasts ar...
