Light and transmission electron microscopy of Vibrio campbellii infection in gnotobiotic Artemia franciscana and protection offered by a yeast mutant with elevated cell wall glucan.

Luminescent vibrios are amongst the most important pathogens in aquaculture, affecting almost all types of cultured organisms. Vibrio campbellii is one of these most important pathogens. In this study, the effects of feeding mnn9 yeast cell wall mutant and wild type yeast strain were investigated in the digestive tract of brine shrimp nauplii, Artemia franciscana, after experimental infection with V.

A method for the specific detection of resident bacteria in brine shrimp larvae.

In this study, we describe an easy but efficient method to specifically target the intestinal resident microbiota in brine shrimp larvae during DGGE analysis, hereby excluding the interference of both transient (luminal) bacteria and body surface bacteria. This effective technique has several advantages over alternative methods, with respect of ease of use and rapidity.

Herpes simplex virus type 1 penetrates the basement membrane in human nasal respiratory mucosa.

Background: Herpes simplex virus infections are highly prevalent in humans. However, the current therapeutics suffer important drawbacks such as limited results in neonates, increasing occurrence of resistance and impeded treatment of stromal infections. Remarkably, interactions of herpesviruses with human mucosa, the locus of infection, remain poorly understood and the underlying mechanisms in stromal infection remain controversial.
