Minute coccobacilliform bodies have regularly been found in the nasal exudate of fowl infected both by injection and by contact with the coryza of slow onset. These bodies are commonly less than 0.5micro in diameter and are predominantly extracellular. They have consistently failed to grow in artificial media. They are held back by Berkefeld V filters which are impermeable to Hemophilus gallina...
A proliferative dermatitis similar to the condition generally referred to as strawberry footrot was observed in two Alpine chamois (Rupicapra rupicapra) from Eastern Alps, Italy. Branching septated filaments and packets of PAS-positive coccoid organisms were observed in histological sections of the affected skin. The actinomycete, Dermatophilus congolensis, was isolated from crusted lesions in ...
Cells of Arthrobacter crystallopoietes mixed in sand and air-dried have survived for up to 6 months after an initial period in which approximately half the cells lost their viability. Comparative survival curves have been obtained from inoculated sands maintained under CaSO(4) or P(2)O(5). Selections for more desiccation-resistant progeny capable of surviving the initial period were unsuccessfu...
Subaerial Freshwater Stromatolites in Deer Cave, Sarawak â•fi A Unique Geobiological Cave Formation
In most cases authors are permitted to post their version of the article (e.g. in Word or Tex form) to their personal website or institutional repository.

Ignisphaera aggregans Niederberger et al. 2006 is the type and sole species of genus Ignisphaera. This archaeal species is characterized by a coccoid-shape and is strictly anaerobic, moderately acidophilic, heterotrophic hyperthermophilic and fermentative. The type strain AQ1.S1(T) was isolated from a near neutral, boiling spring in Kuirau Park, Rotorua, New Zealand. This is the first completed...
The effects of UV irradiation (254 mmu) on a coccoid blue-green alga Agmenellum quadruplicatum, Strain PR-6, have been examined in terms of the survival curve and measurement of short time photosynthetic rates. From study of survival evidence has been found for a strong photoreactivation centered near 430 mmu. Measurements of photosynthetic rate suggest that there is a correlation between decay...
