AIMS Histamine intoxication is probably the best known toxicological problem of food-borne disease. A histamine-producing Staphylococcus capitis strain has been isolated from a cured meat product. The aim of this study was to gain deeper insights into the genetic determinants for histamine production in Staph. capitis. METHODS AND RESULTS The nucleotide sequence of a 6446-bp chromosomal DNA f...

Tinea capitis is a dermatophyte infection that occurs mainly in childhood; there are few reports, in Brazil, in adolescents and adults. The detection of asymptomatic carriers is of great importance in the disease control. From February 1998 to February 1999, a study was performed at the outpatient Dermatologic Unit of Instituto de Puericultura e Pediatria Martagão Gesteira (Universidade Federal...

Tinea capitis caused by Trichophyton tonsurans has been increasing in the United States for the past 25 years. A retrospective study of dermatophyte culture data at the University of California, San Francisco, and a parallel study of patient visits for tinea capitis at an affiliated hospital demonstrates a dramatic rise in Trichophyton tonsurans tinea capitis in the San Francisco Bay area.

BACKGROUND Coagulase-negative staphylococci, mainly Staphylococcus epidermidis, are the most frequent cause of late-onset sepsis (LOS) in the neonatal intensive care unit (NICU) setting. However, recent reports indicate that methicillin-resistant, vancomycin-heteroresistant Staphylococcus capitis could emerge as a significant pathogen in the NICU. We investigated the prevalence, clonality and v...

In recent years, the prevalence of tinea capitis, an infection of the scalp by dermatophytes, has increased in children worldwide. This cross-sectional study was carried out to determine the prevalence and risk factor of tinea capitis among school children in Nok community of Kaduna State, Nigeria. A total of 100 children were screened and 45% were diagnosed to have tinea capitis after fungal c...

tinea capities is the commonest dermatophytosis in children with diverse clinical presentations. the causative fungi of tinea capitis vary with geographic area and time.this study was aimed to identify the etiologic agents and determine the related factors of tinea capitis in tehran, iran. from clinically suspected cases of tinea capitis, microscopy and culture were performed. of 58patients 96%...

Tinea capitis is the most common superficial mycosis in children of school age. Although it is of public health importance, it is not a reportable or notifiable disease; therefore, actual prevalence figures are unknown in many endemic areas. The aim of this work was to determine the prevalence of tinea capitis among primary school children in two states in central Nigeria, highlighting the main...

The head louse, Pediculus capitis De Geer (Phthiraptera: Pediculidae) has developed resistance to organochlorines, the organophosphate malathion and to pyrethroids in the U.K. Therefore, headlice from Bristol school children were bioassayed against two new insecticides, fipronil and imidacloprid. Pediculus capitis was fully susceptible to imidacloprid, but it required a relatively high dose and...
