Disseminated Conidiobolus infection with endocarditis in a cocaine abuser.

A crack cocaine abuser developed disseminated infection caused by a species of Conidiobolus not known to cause disease in vertebrates. The fungus gained entry via skin abrasions on the lower extremities, spread through the hematogenous route, and caused endocarditis. There was evidence of fungal infection in the lungs, heart, kidneys, skeletal muscles, and brain. An additional complication was extensive rhabdomyolysis, with a marked elevation of creatine kinase of up to 1.2 million U/L.

[Natural microbial control of crickets populations (Orthoptera: Gryllotalpidae: Scapteriscus borellii): regulation of populations aggregated in time and space].

From 1983 through 1988, a total of 1,762 collections, containing 31,312 individuals of the mole cricket, Scapteriscus borellii, were made, principally in the State of São Paulo, Brazil. Collections were found to fit a negative binomial distribution both as whole and when divided into monthly collections. In these collections, an iridovirus, a entomogenous nematode, and the fungi Metarhizium anisopliae, Beauveria bassiana, Paecilomyces sp., and Entomophtora sp., were found to be agents of natural mortality, although usually as endozootics and relatively rarely as epizootics and panzootics. As a group, these diseases were also distributed in a binomial negative. These data suggest that the temporal and spatial aggregations of the mole crickets, produced by high rates of migration among suitable habitats, are adaptations to outbreaks of epidemics, which also serve as mole cricket population regulators. These ideas are develop and derived from simple mathematical models of population change.

[Entomophthoromycosis. Review].

A review of the published reports on entomophthoromycosis (rhynoentomophthoromycosis and basidiobolomycosis) is presented. Geographic distribution, clinical, pathologic, mycologic and therapeutic aspects are emphasized. Primary and secondary visceral involvement are discussed. Data concerning 33 Latin American cases are analysed: 21 cases of rhynoentomophthoromycosis and 11 of basidiobolomycosis. Of these cases, 84% were described in Brazil and of the seven reported cases with primary visceral involvement reported in the world literature six were from Brazil. The importance of an early diagnosis of these infections is asserted specially in view of the resulting deformities and even death.

[2 new cases of rhinoentomophthoromycosis diagnosed in the Central African Republic (review of the literature)].

After a historical account and review of the published literature on rhinoentomophthoromycosis, we report two recently recognized cases in Central African Republic. The first case was a 32 year-old "peuhl" woman with typical facial deformation that gave her a "hippopotamus-woman" aspect. The second case was a 53 year-old man with lesions that were less typical and limited to one half of the face only. In both cases, hypodermic nodules were palpable and it is likely that inoculation occurred by scratching of a skin lesion. The woman originates from a savanna region whereas the second patient is from a forest area. In both cases, culture were positive for Conidiobolus coronatus. Treatment with itraconazole was instituted for both patients.

Mitochondrial morphology in Basidiobolus haptosporus.

Young hyphal cells of the potentially zoopathogenic fungus Basidiobolus haptosporus characteristically exhibit unusual proportions of annulate views of mitochondria in the two-dimensional perspective of thin sections. Such views exhibit a central space containing cytoplasmic ground substance and often profiles of other cytoplasmic organelles (lipid bodies, other mitochondrial forms, and especially crystalloid-containing microbodies). Three-dimensional projections are presented to suggest that these mitochondria have assumed the form of a goblet-shaped enclosure, and that the various annulate views are the consequence of plane of section viewed by electron microscopy. Their frequent occurrence and consistent morphology argues against their being random expressions of mitochondrial plasticity, but rather for close spatial associations amongst cytoplasmic organelles of young hyphae. When the fungus is grown on xanthine or its catabolites as sole sources of nitrogen, there is a proliferation of crystalloid-containing microbodies, double-membraned vesicles, and ovate to ellipsoidal mitochondria. Annulate views of mitochondria then are no longer observed, but microbodies again frequently appear in close association with mitochondria and at times in intimate contact with the mitochondrial outer membrane.

Gastrointestinal phycomycosis in 63 dogs.

In a study of 63 cases of canine gastrointestinal phycomycosis, 60 were determined to have pythiosis and 3 to have entomophthoromycosis. In pythiosis, male, large-breed dogs less than or equal to 3 years old were most commonly affected. Clinical signs usually included vomiting and weight loss and these were associated with lesions of the stomach and small intestine. Histologically, the causative organisms were found in necrotic regions of diffuse or discrete granulomas in the submucosa or muscularis mucosae. Entomophthoromycosis was diagnosed by finding wide eosinophilic sleeves intimately surrounding thin-walled hyphae. Less than 5% of the dogs were alive 3 months following diagnosis.

[Phycomycoses].

Phycomycoses are opportunistic fungal diseases as far as mucormycosis is concerned, but for basidiobolomycosis and entomophthoromycosis, the adjective 'opportunistic' should be used with caution. Mucormycosis assumes cranial, pulmonary, gastrointestinal, disseminated, cutaneous and focal forms: the infection nearly always develops in a person whose resistance is lowered by a metabolic disorder, a blood dyscrasia, corticosteroid or immunodepressive therapy. It is a frequent complication in leukemia or diabetic acidosis. Basidiobolomycosis and entomophtoromycosis are caused by fungi which belong to the order, Entomophthorales. They are characterized in tissue by broad hyphae which are surrounded by eosinophilic material. These mycoses are treated by potassium iodide.
