Forensic Plant Pathology. MOORE Plant Pathology Laboratory, Harpenden In introducing the session on seed-borne fungi, Mr Moore said: I do not intend to stand between you and the speakers for more than a few minutes but, as was indicated in the preliminary announcement about these meetings, the papers selected were designed to show, as far as is possible in the time allotted, the relation of mycology to other subjects.
This morning we are concerned with its relation to plant pathology, and I have been asked to make a few comments on this. Now the relationship should not be difficult to define if everyone were agreed about what mycology and plant pathology are, or about the difference between a mycologist and a plant pathologist.
But, unfortunately, in practice there seems to be a good deal of confusion about this, both nationally and internationally. In this country, where the study of plant diseases has, until comparatively recently, been dominated by investigations of plant pathogenic fungi, no clear distinction has been made between mycology and plant pathology, or between mycologists and plant pathologists. For very many years the official adviser in plant diseases to the Ministry of Agriculture and Fisheries has been called the Ministry's Mycologist, in contrast with the Entomologist, who was concerned with plant pests.
Specialists in plant pathology at the Research Stations have generally been called Mycologists, and for twenty-five years there has been a special corps of Advisory Mycologists on the staffs of the Universities and Agricultural Colleges, who have been concerned with giving advice in the whole field of plant diseases. Change, if not clarification, is now taking place. At Headquarters there are posts for both Plant Pathologist and Mycologist, though the distinction is still a nominal one: under the new National Agricultural Advisory Service the corps of Advisory Mycologists has become an official corps of Advisory Plant Pathologists: and at the Research Stations and elsewhere there is a growing tendency to try to get away from using the terms 'Mycology' and 'Mycologist' with omnibus meanings.
Abroad, the terms we have used are replaced by 'Plant Pathology' or 'Phytopathology' and' Plant Pathologist', which cover more or less the same field, except that in certain countries plant diseases caused by eelworms fall within the scope of Plant Pathology, whereas in this country they are regarded as the concern of the entomologist and not of the 'mycologist'. To me the relation between mycology and plant pathology presents no difficulty when a rational view is taken of the two subjects.
Mycology is the science of fungi or, if you prefer, the branch of botany dealing with fungi, and those who study it are Mycologists. As such it comprises many different things, including the taxonomy of fungi, their collection and Mycology and Plant Pathology. Moore 65 preservation, their biology and nutrition, their uses in medicine and industry, and the part they play in diseases of plants, animals, insects and man. Plant Pathology is a science treating of plant diseases, their nature, cause, progress and results: it is concerned with the pathological condition of plants, whatever the origin of that condition.
The subject should therefore be regarded as comprising the study of plant diseases caused by fungi, algae, bacteria, viruses and eelworms; the study of plant pests; and of the vast field of nutritional or physiological disorders.
These parts form a natural whole, and it is no longer possible to separate them, or to attempt to separate them, into watertight compartments. Entomology is bound up with the study of virus diseases; eelworms and fungi are often closely linked; and the incidence of both pest and disease is dependent on nutrition and environment. On the other hand, it does not follow that those who study plant pathology are necessarily to be labelled plant pathologists, in the way that I prefer to use the term.
There is undoubtedly a place in advisory work for the general plant pathologist who is familiar with the nature and control of all the common troubles that lead to sickness in plants, but for the most part the subject provides common ground for the mycologist, entomologist, virus worker, helminthologist, bacteriologist, nutrition or soil chemist, and plant physiologist, each specializing along his own lines, but collaborating closely with cognate branches.For advanced searches select one of the databases above.

Email address.Laboratory Handbook of Medical Mycology summarizes the concepts dealing with the laboratory aspects of medical mycology. The publication first offers information on basic terminology and classification, laboratory safety, and clinical specimens.
Discussions focus on tissue, abscess, blood, bone marrow, and urine specimens, biological hazards, disinfection and sterilization, grounding of electrical equipment, waste disposal, asexual and sexual reproduction, and vegetative growth. The text then takes a look at mold and yeast identification, including fermentation, temperature studies, asci and ascospores, zygomycetes, cycloheximide resistance, and sporulation and sterile isolates.
The manuscript ponders on susceptibility testing and bioassay procedures, culture collection, and quality control.
Topics include proficiency evaluations, media and equipment control, depositing unusual isolates in major culture collections, reconstituting lyophilized cultures, bioassay to determine drug levels in body fluids, and in vitro susceptibility testing.
The publication is a dependable source of data for laboratory technologists, microbiologists, and mycologists engaged in safely isolating and accurately identifying fungi of medical importance.

They do not contain chlorophyll and are not plants. Medical mycology is mostly concerned with microfungi, specifically zoopathogenic fungi. They grow in two forms: Mold A non-motile thallus constructed of apically elongating walled filaments hyphae.
A web of filaments constitutes a mycelium Figures 1 and 2 Yeast blastoconidia. A unicellular fungus that reproduces by budding. Small, round projections from the ellipsoid shaped parent cell are produced during mitosis followed by migration of the nucleus and cytoplasm into the bud. Finally, cytokinesis occurs forming a new daughter cell.
Buds may be solitary or in chains. Some yeasts multiply by fission. Events in the yeast cell cycle are finely orchestrated. A visual 3-D representation of the yeast cell cycle can be found here.
Candida albicans is a yeast-like fungus that grows in a variety of forms: yeast, pseudohyphae a transitional form and hyphae. Pseudohyphae can give rise to yeast cells by apical or lateral budding.
Yeast can also convert to a hyphal form. All three forms are found in tissue invaded by the fungus. Figures 3 A - C show C. Figure 4 shows a colony of yeast and of a mold growing in agar plate cultures. Most are saprobes that decompose dead organic matter. Plant pathogenic fungi cause damage to food crops, trees, and other plants. Various estimates of the number of fungal species range upwards of 1 million Heitman, About species are known human pathogens but any fungus capable of growth at 37 degrees C is potentially pathogenic in a suitably compromised host.

Cell walls Bacterial cell walls contain peptidoglycan, lipopolysaccharide, and teichoic acid. Fungal walls contain glucan, mannan, and chitin.
