“…The wall composition of S. pombe differs to some extent from that of the budding yeast. In addition to β-glucans (46 to 54%) which seem to be qualitatively comparable to those of the budding yeast, the S. pombe cell wall contains a substantial amount of a linear 1,3-α-glucan (18 to 28%) and a galactomannnan (9 to 14%) instead of mannan (Bacon et al, 1968;Bush et al, 1974;Manners et al, 1974;Manners and Meyer, 1977;Horisberger and Rosset, 1977). Chitin is a component that may have some roles in morphogenesis, via the formation of a complex with β-glucans in several genus of Ascomycetes.…”

SUMMARYIn animal cells, cytokinesis requires the formation of a cleavage furrow that divides the cell into two daughter cells. Furrow formation is achieved by constriction of an actomyosin ring that invaginates the plasma membrane. However, fungal cells contain a rigid extracellular cell wall surrounding the plasma membrane; thus, fungal cytokinesis also requires the formation of a special septum wall structure between the dividing cells. The septum biosynthesis must be strictly coordinated with the deposition of new plasma membrane material and actomyosin ring closure and must occur in such a way that no breach in the cell wall occurs at any time. Because of the high turgor pressure in the fungal cell, even a minor local defect might lead to cell lysis and death. Here we review our knowledge of the septum structure in the fission yeastSchizosaccharomyces pombeand of the recent advances in our understanding of the relationship between septum biosynthesis and actomyosin ring constriction and how the two collaborate to build a cross-walled septum able to support the high turgor pressure of the cell. In addition, we discuss the importance of the septum biosynthesis for the steady ingression of the cleavage furrow.

“…Various fluorescent lectins were used to identify six fungal species associated with systemic disease (151 probe to detect galactomannan on the cell walls of Schizosaccharomyces pombe by scanning and transmission electron microscopy (72). The lectin from the brown alga Fucus vesiculosus agglutinates Candida guilliermondii cells.…”

Lectins are generally associated with plant or animal components, selectively bind carbohydrates, and interact with procaryotic and eucaryotic cells. Lectins have various specificities that are associated with their ability to interact with acetylaminocarbohydrates, aminocarbohydrates, sialic acids, hexoses, pentoses, and as other carbohydrates. Microbial surfaces generally contain many of the sugar residues that react with lectins. Lectins are presently used in the clinical laboratory to type blood cells and are used in a wide spectrum of applications, including, in part, as carriers of chemotherapeutic agents, as mitogens, for fractionation of animal cells, and for investigations of cellular surfaces. Numerous studies have shown that lectins can be used to identify rapidly certain microorganisms isolated from a clinical specimen or directly in a clinical specimen. Lectins have been demonstrated to be important diagnostic reagents in the major realms of clinical microbiology. Thus, they have been applied in bacteriology, mycology, mycobacteriology, and virology for the identification and/or differentiation of various microorganisms. Lectins have been used successfully as epidemiologic as well as taxonomic markers of specific microorganisms. Lectins provide the clinical microbiologist with cost-effective and potential diagnostic reagents. This review describes the applications of lectins in clinical microbiology.
