Laboratory and clinical assessment of ketoconazole in deep-seated mycoses.

Forty-eight cases of deep mycoses were studied and treated with ketoconazole, each with in vitro evaluation of the minimum inhibitory concentrations (MIC) of the causative fungi, in vivo pharmacokinetic, clinical, and mycologic evaluations, several months to two years after the treatment was stopped. Excellent results were obtained in six cases of chronic mucocutaneous candidiasis, with restoration of immunologic disturbances; 23 cases of systemic candidiasis, including new aspects of heroin addicts with cutaneous, ocular, or osteoarticular manifestations; eight cases of histoplasmosis, five due to Histoplasma capsulatum and three to Histoplasma duboisii, with cure in seven and remission in one; one case of African blastomycosis (Blastomyces dermatitidis); three cases of mycetoma, two due to Monosporium apiospermum, one due to a dematiacious fungus; three cases of entomophthoromycosis with cure; one case of fungal arthritis, due to new hyphomycete similar to M. apiospermum, pathogenic for laboratory animals; one case of Drechslera longirostrata causing vertebral arthritis, following a fungal endocarditis and cured by combination of ketoconazole with amphotericin B, each agent alone being ineffective; and other deep mycoses.

Immunological separation of Entomophthorales genera.

Exoantigens from Erynia neoaphidis, Conidiobolus major, C. thromboides, C. obscurus, Zoophthora radicans, and Basidiobolus ranarum were obtained from culture filtrates of fungal material grown in a yeast extract, peptone dialysate, dextrose medium and were tested against specific hyperimmune antisera prepared from E. neoaphidis, C. major, C. thromboides, and B. ranarum by the immunodiffusion technique. Specific precipitins were observed for E. neoaphidis and B. ranarum, while cross-reactions were detected among C. major, C. thromboides, and C. obscurus. The results suggest that genera of Entomophthorales can be easily separated by this simple immunological procedure.

Basidiobolomycosis: an unusual fungal infection mimicking inflammatory bowel disease.

Basidiobolus ranarum is a fungus belonging to the Entomophthoraceae family and is mainly associated with subcutaneous soft tissue infection. The disease is usually characterized by an insidious onset of massive induration of the subcutaneous tissue involving the limbs, trunk, or buttocks. Most cases of basidiobolomycosis have been reported from Africa, South America, and tropical Asia. Visceral involvement is extremely rare. Only 4 cases with involvement of the gastrointestinal tract, including 1 fatal case originating in the United States, have been well documented in the English-language literature. This case report describes the first successfully treated patient residing in the United States who had B. ranarum infection involving the gastrointestinal tract.

Effect of spatial heterogeneity on the role of Coccinella septempunctata as an intra-guild predator of the aphid pathogen Pandora neoaphidis.

The foraging behavior of starved and non-starved adult and larval Coccinella septempunctata on groups of plants in the presence of Pandora neoaphidis-infected Acyrthosiphon pisum, uninfected aphids or a mixture of these two prey types was compared. In general results of these studies confirmed the results of previous work comparing foraging behavior on a smaller spatial scale in Petri dishes. However, behaviors were modified in response to spatial complexity, prey quality, and the host plant. Starved C. septempunctata adults and larvae fed for longer and consumed more aphids than non-starved coccinellids. Both larvae and adults fed on infected aphids and in some cases entirely consumed them. This was thought to be due to the ease of capture of infected (dead) aphids and the feeding stimuli provided by the presence of the host plant and, where there was a choice of prey, uninfected aphids in the environment. Both larvae and adults spent the majority of the time foraging in the upper regions of plants and visited more plants when they were not starved or when they were in the presence of less suitable, infected aphid prey.

Effects of long-term storage at -14 degrees C on the survival of Neozygites fresenii (Entomophthorales: Neozygitaceae) in cotton aphids (Homoptera: Aphididae).

Neozygites fresenii-infected Aphis gossypii cadavers, containing dormant hyphal bodies of N. fresenii, were stored in 4 ml glass vials at -14 degrees C in a standard consumer-type refrigerator/freezer for 1, 21, 30, 43, 51, and 68 months to determine the effect of storage on fungal survival. When the cadavers were removed from the freezer and placed in 25+/-1 degrees C, 100% relative humidity, and 12:12 (L:D) conditions, N. fresenii survival, as shown by fungal sporulation from the cadavers, was high at all storage periods. The average percentage of cadavers from which the fungus sporulated were 93, 47, 100, 100, 80, and 60% from 1, 21, 30, 43, 51, and 68 months storage periods, respectively. The number of primary conidia discharged from each sporulating cadaver was estimated using a scale of 1 (low, ca. 1000 primary conidia), 2 (medium, ca. 2000 primary conidia) and 3 (high, ca. 3000 primary conidia). The median scores for the number of primary conidia produced per sporulating cadaver were 3, 2, 3, 3, 2.5, and 1 for 1, 21, 30, 43, 51, and 68 months, respectively. Therefore, except for the longest storage period, most cadavers produced medium to high numbers of primary conidia. Mean germination of primary conidia produced from N. fresenii-infected-aphid cadavers from each time period varied significantly from 66.3 to 86.1% in the 21 and 43 months categories, respectively. Infectivity of capilliconidia, produced from frozen N. fresenii, to live healthy cotton aphids varied significantly from 16.7 to 68.7% from cadavers stored 68 months and 1 month, respectively. Overall N. fresenii survived well in dried frozen cotton aphid cadavers for up to 6 years with little reduction in sporulation, numbers of spores produced, germination of primary conidia, or infectivity.

Development of severe secondary hypertension in a patient with systemic entomophthoromycosis.

The sudden onset of hypertension mandates investigation for secondary causes. We report the case of a young man with a very rare systemic fungal disease that included massive unilateral perirenal adenopathy. Treatment was associated with the abrupt onset of severe hypertension. Imaging studies suggested progressive constriction of one kidney with treatment, presumably as a result of healing adenopathy. We suggest that this case is a new example of hypertension secondary to constrictive perinephritis (Page kidney).

Entomophthoromycosis caused by Conidiobolus coronatus: clinicomycological study of a case.

A case of midfacial swelling in a middle aged woman proved to be caused by a fungus Conidiobolus coronatus has been reported. It is a very rare condition and the knowledge of this fungus affecting the rhinofacial region in human started since 1965 only. These cases pose diagnostic problem. The treatment with the combination of ketoconazole and the saturated solution of potassium iodide was effective for this fungal infection.

Electron cytochemical demonstration of phosphatase activity with microbody membranes of Basidiobolus haptosporus.

Growth of cells of the potentially zoopathogenic fungus Basidiobolus haptosporus on a nutritionally defined medium with xanthine or urate as the nitrogen source results in greatly increased populations of microbodies. Modified Gomori procedures at the electron microscopic level suggested the single limiting membrane (and in some cases the granular matrix) of immature microbodies to be the exclusive subcellular locale(s) of alkaline phosphatase, 5'-nucleotidase and nucleoside diphosphatase activities. When grown in the presence of low inorganic phosphate, additional alkaline phosphatase activity was further identified cytochemically at and along profiles of endoplasmic reticulum and on inclusions previously described as "double-membraned vesicles". Cytochemical localization of acid phosphatase at microbody membranes was minimal if not ambiguous; Mg++-dependent adenosine triphosphatase and glucose-6-phosphatase were not identified at these locales. Quantitative biochemical estimates of alkaline phosphatase activity levels in particulate fractions initially increased with age of cells, perhaps as a function of the cultural induction and marked increase in immature microbody populations. We suggest that this enzyme may participate in some manner with protein translocation mechanisms associated with microbody biogenesis, ontogeny, and/or physiological function.
