Microbacterium sp

Microbacterium paraoxydans sp. nov
Cells of Microbacterium paraoxydans (pa-ra-o′-xy-dans, because the organism resembles M. oxydans) are small, gram-positive, coryneform rods that grow aerobically at 20, 37, and 40°C. Colonies are bright yellow, smooth, and sometimes sticky and reach a diameter of 2 mm after 48 h of incubation at 37°C on blood agar. Strains are motile by peritrichous flagella

Aerobic heterotrophic bacterium found in soil and other environments. Some species are opportunistic pathogens.

Among the coryneform bacteria, the phenotypically and phylogenetically closely related genera Microbacterium and Aureobacterium have been united in the redefined genus Microbacterium.At present, the genus Microbacterium comprises 55 species (www.bacterio.cict.fr/m/microbacterium.html), all of which exhibit more or less yellow-pigmented gram-positive rods

Mycellia sterillia

The sterile fungi, or mycelia sterilia are a group of fungi that do not produce any known spores, either sexual or asexual. This is considered a form group, not a taxonomic division, and is used as a matter of convenience. Because these fungi do not produce spores, it is impossible to use traditional methods of morphological comparison to classify them. However, molecular techniques can be applied to determine their evolutionary history.

Aeromonas veronii

Aeromonas veronii is a gram-negative, rod-shaped bacterium found in fresh water and in association with animals. It can be a pathogen of humans and a beneficial symbiont of leeches. In humans A. veronii can cause diseases ranging from wound infections and diarrhea to septicemia in immunocompromised patients. In leeches, this bacterium is thought to function in the digestion of blood, provision of nutrients or preventing other bacteria from growing.

Cladosporium sp



Colonies are rather slow growing, mostly olivaceous-brown to blackish brown but also sometimes grey, buff or brown, suede-like to floccose, often becoming powdery due to the production of abundant conidia. Vegetative hyphae, conidiophores and conidia are equally pigmented. Conidiophores are more or less distinct from the vegetative hyphae, are erect, straight or flexuous, unbranched or branched only in the apical region, with geniculate sympodial elongation in some species

Cladosporium species have a world-wide distribution and are amongst the most common of air-borne fungi. Some 500 species have been described. Isolates of Cladosporium are frequently isolated as contaminants.

Candida parapsilosis

Candida parapsilosis is not an obligate human pathogen, having been isolated from nonhuman sources such as domestic animals, insects or soil. Candida parapsilosis is also a normal human commensal and it is one of the fungi most frequently isolated from the human hands.

On Sabouraud's dextrose agar colonies are white to cream colored, smooth, glabrous and yeast-like in appearance.
Environmental isolations have been made from intertidal and oceanic waters, pickle brine, cured meats, olives and normal skin, and faeces.

Candida guilliermondii

On Sabouraud's dextrose agar colonies are white to cream colored, smooth, glabrous and yeast-like in appearance.
C. guilliermondii has also been isolated from normal skin and in sea water, faeces of animals, fig wasps, buttermilk, leather, fish and beer.
