Toxocarosis and paratenic hosts

The seroprevalence rates of human toxocarosis figured up to 24.5% versus Toxocara canis and 22.1% versus Toxocara vitulorum in some selected localities in Egypt, using enzyme linked immunosorbent assay technique. Toxocara vitulorum larvae in experimentally infected mice and rats follow the same manner of migration previously described for T.canis with more adaptation to mice than rats as paratenic host. This study clarifies the role of rodents in maintaining Toxocara larvae and spread of infection to other host

Occupational nail mycoses in a veterinarian

Mycological examination was carried out to assess the etiological agent of nail infection in a Veterinarian occupationally involved in mycological investigations. Scopulariopsis infection of the nail was confirmed macroscopically and microscopically. Successful treatment was achieved by oral administration of ketaconazol and topical application with isoconazol sol

possible role of domestica in transmitting fungal agents

Twenty two fly [M.domestica] samples were collected from cattle byres, poultry houses and human houses in different localities to investigate the possible role of flies in transmitting pathogenic fungi. A. terreus A. flavus and mucor spp. were isolated from the flies. In addition yeasts [C.albicans and others] were recovered. Great number of fungal isolates were recovered from cattle byre's flies while few isolates were recovered from flies of poultry houses and human houses; respectively

Aspergillus fumigatus a possible cause of nasal and frontal sinuses affections of dogs and man

A total of 53 stray dogs and 23 pet dogs as well as 17 owners were included in a study to find out the incidence of Aspergillus fumigatus in their nasal cavities. Aspergillus fumigatus was recovered from 40% and 61.11% of symptoms stray dogs and those showing nasal discharge respectively, while the respective values for pet dogs were 16.677% and 50%. Examination of the owners of pet dogs revealed an incidence of 16.67% for symptomless cases and 40% in those showing nasal discharges. It was concluded that the localization of Aspergillus fumigatus in the nasal cavities of a high percentage of both stray and pet dogs will definitely facilitate transmission of the mould to other dogs and man. Public health education is essential to give instruction on the hazardous nature of stray dogs. Also, periodical check-up of pet dogs is recommended

possible role of contaminated air-conditioning sets in the transmission of zoophylic fungi to man

The role of contaminated air conditioning sets in the dissemination of fungi into closed areas was investigated. Air samples were collected while the sets were switched hot, cold and off. The fungal isolates were identified. It was concluded that air conditioning sets may help in the dissemination of fungi in closed places especially when found in contaminated environment or when flying birds [pigeons, sparrows' etc]. soil their metal backs with their excreta
