The indoor airborne fungi.

Air, indoor or outdoor, is never completely free of fungal spores; however, their types and quantities will depend upon geographic location, the time of the day or year, meteorological conditions, and surrounding flora and fauna. The influence of the outdoor fungal flora on the indoor has been documented; however, it is an accepted fact that the indoor airborne fungi, regardless of the type of homes or dwellings, come from two sources: the outdoor air and the indoor fungal colonization. Such colonization found mainly in the basement, followed by the bathroom, the kitchen and every wet, dark and poorly ventilated area of the home. Preventing a home from becoming mouldy is ten times easier than trying to eliminate the fungal colonization within such a home.

Further studies of the airborne fungi and pollens of the Washington, D.C. metropolitan area.

Airborne fungi and pollen grains were studied during 1981 in two locations in the Washington, D.C. metropolitan area. This is a follow up of a 1977 survey of the same area to determine the prevalence of types of fungi and pollens. Dominant fungi were Hormodendrum (October), Penicillium (July) and Alternaria (September), whereas predominant pollens were oak (April), pine (April) and ragweed (September).

Airborne fungi and pollens of the Washington, D.C., metropolitan area.

Moulds and pollen allergies are common in the Washington, D.C., metropolitan area. In this survey airborne fungi and pollen grains were studied throughout 1977 by weekly sampling for determination of prevalence of types of fungi and pollens. Dominant pollen types were oak (April), pine (April) and ragweed (September), whereas those of fungi were Hormodendrum (June) and Aureobasidium (March).

Pathological studies in experimental Candida endocarditis.

Mycotic endocarditis was produced in rabbits by indwelling intracardiac catheters filled with a suspension of Candida albicans. Grossly, cardiac lesions consisted of massive fungoid valvular vegetations and/or "sleeve thrombi" surrounding the catheter. Microscopically, platelet-fibrin aggregates were observed to be loosely attached to the valvular cusps. With time, the vegetations became organized and more firmly attached against the endocardium. Also observed was a heavy neutrophylic collar often containing Candida cells which infiltrate the subendothelial tissues of the valvular cusps. Sterile endocardial lesions were produced by retained catheters. The lesions consisted of discrete, glistening, hemispherical nodules in the right heart; and similar elevated plaques on the mural endocardium of the left ventricle. Microscopically, these lesions consisted of fibrous connective tissues devoid of inflammatory cells. The lesions in the left ventricle were more extensive, extending into the myocardium.

Quantitative Studies of Total Lipids of Pathogenic Fungi.

Ten species of dermatophytes and four of the systemic fungi were assayed for total lipids, acetone-soluble fraction, and phospholipid content in different types of cultures. The yeast phase of each of the systemic fungi grown on solid medium exhibited a higher total lipid content than did the mycelial growth in liquid medium, either shake or still. Shake cultures, in all the fungi tested, produced the least lipids. The yeasts were consistently higher also in the acetone-soluble fraction. Histoplasma duboisii in the yeast phase and Microsporum gypseum produced the greatest amount of phospholipid, and Blastomyces dermatitidis in the yeast phase and M. canis produced the largest acetone-soluble fraction among the systemic fungi and dermatophytes, respectively.
