    Notes: Abstract Several foci of lobomycosis among Colombian Amer Indians population were described in the Casanare region of Colombia, near the Orinoco river on the Colombian-Venezuelan border. This paper reports 16 new patients. The prevalence of Lobo's disease was 8.5% in the Amoruas tribe. Nodular lesions were located on the elbow, scapular and lumbar regions, knees, feet and legs. Leg lesions were especially numerous, were confluent and tended to ulcerate. All cases were confirmed histologically. Two Negro patients were also described. The cases bring the total number of confirmed patients with lobomycosis in Colombia to 41. Twenty-five of these were Amer Indian patients from tribes living in the Orinoco and Amazon basins of the country.

    Notes: Abstract One hundred and twelve nasal polyps received along with full history from three different hospitals of Kanyakumari district of Tamil Nadu during the period 1983–1987 were found positive for rhinosporidiosis on histopathological examination. Among the four taluks (countries) the majority of the cases (41.1 per cent) came from Agastheeswaram, followed by Kalkulam (28.6 per cent), Thovalai (17.0 per cent) and Vilavancode (13.3 per cent). The 11–20 years age group found to be highly susceptible (60 per cent). There was no sex prepondence in contracting the disease as the cases were evenly distributed between both sexes. These findings exhibited the endemic nature of the disease in Kanyakumari district. Unreported cases to an extent of 9 to 40 per cent were encountered during the ENT disease diagnostic camps conducted in nine high incidence villages. Further 8 more cases were detected in addition to cases attended in the hospitals and ENT camps when a complete enumeration of cases was undertaken in Pallam village. Thus the actual number of cases found in the district need a stratified random sampling.

    Notes: Abstract The mycoflora of the hair in 285 sheep from the West Bank of Jordan was analysed and the frequency of occurrence and the relative importance value for different fungal species found were calculated. Ninenty six species which belong to 36 genera were isolated. Forty one of these species were either well-known agents of animal and human mycoses (Trichophyton verrucosum, T. mentagrophytes, Microsporum nanum, M. canis, and others), or have been isolated from human and animal lesions (Arthroderma cuniculi, A. curreyi, Chrysosporium tropicum, Acremonium kiliense, Aphanoascus fulvuscens, Aspergillus versicolor, Paecilomyces lilacinus, Scopulariopsis brevicaulis, and others). These pathogenic fungi comprised 75.4% of all fungi recovered from the hair of sheep. This animal seems to represent an adequate reservoir for several dermatophytes and several potentially pathogenic fungi.

    Notes: Abstract The objective of this study was to characterize the epidemiology of candidemia in cancer patients in the city of Rio de Janeiro, Brazil. An 18-month survey of fungemia in patients with cancer was undertaken in three Hospitals in Rio de Janeiro. Forty-three episodes of candidemia were identified in 43 patients, 43 of which were episodes of candidemia; in ten cases the strains were not available for further identification of species and were excluded from this analysis. The overall distribution of fungi causing fungemia was: Candida albicans (5), Candida tropicalis (16), Candida parapsilosis (6), Candida guilliermondii (4), Candida lusitaniae (1) and Candida stellatoidea (1). Antifungal prophylaxis had been administered before the episode of fungemia in only six patients (18.2%): oral itraconazole in three patients and oral nistatin, low dose intravenous amphotericin B and oral fluconazole in one patient each. There was no difference in the presence of risk factors, clinical characteristics or in the outcome between albicans and non-albicans species, nor between Candida tropicalis and other non-albicans species. There was a clear predominance of non-albicans species, regardless of the underlying disease, antifungal prophylaxis or the presence of neutropenia.

    Notes: Abstract The etiology and epidemiology of concentric leaf spot and seedling blight diseases of yam (Dioscorea spp) was investigated at Jbadan, south western Nigeria, in the low land humid tropics. Sclerotium rolfsii was associated with the concentric leaf spot and seedling blight of yam. The pathogen was also harbored by weeds namely Mucuna pruriensis, Commelina erecta, ipomea triloba, I. involucrataand Ipomoea sp found growing within the yam plots. A high mean inoculum densities of 3.0 ± 0.5 × 106 colony forming unit/g of soil was estimated in the soil samples obtained from the yam plots

    Notes: Abstract A retrospective study of 325 cases of chromoblastomycosis diagnosed in the last 55 years in the Amazon region was carried out by the main Mycology services of the state of Pará, Brazil (Department of Tropical Pathology – UFPA and Mycology Department of the Evandro Chagas Institute/FNS). The data obtained showed that: (a) the main age group affected by the diseases range from 41 to 70 years-old, (b) 86.1% of the patients were agricultural-workers, (c) 93.2% of them were males and (d) 80.7% showed lesions on the lower limbs (feet and legs). The diagnosis of 62% of the cases was confirmed by laboratory studies considering the tissue form in histopathological analysis. In 24% of patients (78 cases), the etiological agent was isolated and identified through culture. Fonsecaea pedrosoi was present in 77 cases and Phialophora verucosa in only one case.

    Notes: Abstract Fungal opportunistic infections are a danger for immunocompromised hosts, such as patients with malignancies, especially in a hospital environment. We studied a group of patients with solid tumors of the respiratory tract on admission and after twenty days of hospitalization. Colonization by moulds and/or yeasts was frequently found. Preventive measures should be applied to avoid colonization inside the hospital. The importance of overcrowding, sanitation and diet is pointed out.

    Notes: Abstract The known African cases of blastomycosis to 1987 are presented, including thirteen previously undescribed cases. This brings to 81 the total number of cases known to have occurred in Africa. The question of whether the disease in Africa is the same in all respects as that in North America is addressed; the age and sex distributions of patients are similar. Minor differences in the clinical features relate particularly to the type of skin lesion, the more frequent bone involvement and the less frequent central nervous system involvement in the African patient. Little is known about the epidemiology of blastomycosis in Africa; one noteworthy feature is the apparent absence of the disease in dogs. Isolates of Blastomyces dermatitidis from the two continents, although closely related, differ in some respects.

    Notes: Abstract The mycoflora of hair of 111 cows, donkeys, rabbits, cats, and dogs were analysed and the frequency of occurrence and the relative importance value of the different fungal species isolated were calculated. Total numbers of species 56, 45, 48, 23, and 11 were recovered from cows, donkeys, rabbits, cats, and dogs respectively. The majority of the keratinophilic fungi isolated were either well-known mycotic agents or have been recovered from various animal and human lesions. These comprised 87.8%, 66.7%, 61.4%, 59.3%, and 55.2% of the hair mycoflora in cats, dogs, rabbis, cows, and donkeys respectively. Seven species of dermatophytes were isolated: Trichophyton mentagrophytes, T. verrucosum, Microsporum gypseum, M. nanum, T. ajelloi, and M. canis. Cats harboured the largest number of dermatophytes (5 species), followed by cows (4 spp), rabbits (3 spp), and donkeys and dogs (1 sp). The role of these animals in the persistence and transmission of pathogenic fungi is discussed.

    Notes: Abstract A microbiological study was carried out in the burn-care unit of the Centro Traumatologico Ortopedico of Turin (Italy) in order to detect the most important sources of fungal contamination in patients at high risk of infection. Identification of the fungi was carried out only for those of medical mycological interest, with the exclusion of the yeast isolates.
