Human otoacariasis.

Accidental entry of insects and other arthropods is a common aetiology of aural foreign bodies (FB) presenting to accident and emergency departments. A retrospective study revealed that the FB in almost half (148) of 348 cases of aural FB investigated at the Universiti Sains Malaysia Hospital was an arthropod. The most common arthropod encountered was the cockroach, followed by a cattle tick. The high prevalence of tick infestation of the human ear canal (i.e. human otoacariasis) currently appears to be unique to the Malaysian state of Kelantan. The presentation of patients with intra-aural ticks, the methods used to remove the ticks, the complications encountered, and recommendations for an appropriate course of action in such cases are discussed.

Natural occurrence of Nocardia in soil of Tucumán: physiological characteristics.

This is the first study initiated in Argentina to establish the presence of species of Nocardia from soil samples. These samples were gathered in different areas of Tucumán. Thirty three pathogenic strains of Nocardia were isolated by the paraffin bait method. Out of them, 28 were N. brasiliensis, 3 N. asteroides and 2 N. caviae. N. brasiliensis was widely distributed in the soil of the areas tested. It is proved that N. caviae, so rarely found in other regions of the world, occurs in Tucumán. A detailed study of the morphological and physiological characteristics for identification is discussed.

In vivo determination of phagocytic indices and candidacidal activities of Candida species by rat peritoneal macrophages.

A possible correlation between pathogenesis and phagocytosis is established through comparison of the kinetics of the ingestion of nine Candida species by rat peritoneal macrophages in the early stages of infection. After 3 h of intraperitoneal injection of 6.10(8) yeasts to Sprague-Dawley rats, the phagocytic indices, candidacidal activity and the fate of the yeasts are assayed. Phagocytic indices allow separation of the species into four groups. Candidacidal activity and phagocytic indices are coincidently smaller in the more pathogenic species. Common events occur with the species assayed. All the yeasts can be isolated from blood, spleen and kidneys from the first h, whilst invasion to liver occurs from the second h post-infection.

In vitro determination of phagocytic indices of Candida berkhout species by rat peritoneal macrophages.

The aims of this investigation were to study and describe the behaviour of 13 different species of Candida, as compared with C. albicans, by means of phagocytosis assays in vitro. Tests were carried out with rat peritoneal macrophages in contact with quantified suspensions of live yeasts. Phagocytic indices, candidacidal activity and filamentation rat were tested microscopically after 3 h incubation at 37 degrees C. The phagocytic indices obtained allowed us to separate the fungi into four groups. Candida albicans and tropicalis belong to Group I; diddensii and shehatae, among others, belong to Group II; sake, krusei, viswanathii, etc., Group III; and C. glaebosa and haploid strains of Pichia ohmeri (C. guilliermondii var. membranaefaciens), Group IV. These data would suggest a possible correlation between pathogenesis and phagocytic indices. There were no evidences of any phagocytes ability to kill yeasts. Candidacidal activity was absent in the species assayed. Yeast lysis may have been observed if our assays would have taken longer than 3 h.
