Unicellular green algae infected and disseminated in two adult Nellore brown rams in India. At necropsy multiple green lesions were observed in the lungs, liver and kidneys of both sheep. Histological examination revealed necrotizing granulomas that contained numerous spheroidal to elliptical organisms ranging from 5-20 micrometers in diameter. These(More)
The acquired immune deficiency syndrome (AIDS) manifested by severe opportunistic infections, Kaposi's sarcoma, or lymphoma often has a prodrome of lymphadenopathy accompanied by constitutional symptoms. We studied the histopathologic findings of lymph node biopsy specimens and peripheral blood immunologic parameters of 24 clinically indistinguishable(More)
We treated six patients with unilateral malignant astrocytomas with pulse doses of intra-arterial BCNU (200 mg/m2 initially, with escalating doses every 6-8 weeks) via transfemoral selective internal carotid catheterization. Four patients had had partial resections without prior radiation therapy and received no steroids. They had decreased tumor stain and(More)
A 32-year-old male patient developed headaches, vomiting, blurring of vision, and focal seizures of the left side of the face 2 months after a renal transplant. He developed a brain abscess and died. Direct KOH examination of the brain tissue demonstrated hyaline as well as dematiaceous, septate hyphae. Histologic examination of brain sections revealed(More)
The first case of subcutaneous zygomycotic infection caused by Saksenaea vasiformis in a rice mill worker from India is described. The infection, confined to the man's left foot, showed multiple draining sinuses, inflammation, and intermittent low-grade fever following a crushing injury when a log fell on his foot. Histopathologic examination of two biopsy(More)
We investigated the potential of 33 different zygomycete isolates to cause cerebral disease following the intranasal instillation of their spores into ketotic rabbits with alloxan induced diabetes. The isolates represented six thermotolerant species of Rhizopus (R. arrhizus, R. chinensis, R. microsporus, R. oligosporus, R. oryzae, and R. rhizopodiformis),(More)
