Plant fertilization is achieved through the involvement of various pollen-pistil interactions. Self-/non-self-recognition in pollination is important to avoid inbreeding, and directional and sustainable control of pollen tube growth is critical for the pollen tube to deliver male germ cells. Recently, various secreted peptides (polypeptides) have been reported to be involved in cell-cell commun...

The capacity of stem cells of peritonium of mesodermal origin to undergo metaplastic transformation and form different tissues developed from mesoderm germ layer is exploited with ulterior motive to use it in the management of human diseases. The excised fallopian tube was replaced with a tube on a stent constructed from autogenous peritoneum from a suitable donor site. The effect of the surrou...

Hydrophobic components of the germ tube of the dimorphic pathogenic fungus Candida albicans were used as immunogens to prepare monoclonal antibodies (MAbs). Among the resulting MAbs, one (MAb 16B1-F10) was shown by indirect immunofluorescence to be specific to the surface of the mycelium phase of the C. albicans and C. stellatoidea species. No labeling of any other genera and Candida species te...

Backround: Candida species take the fourth place among the microorganisms which cause hospital infections. New therapeutic agents are needed because of rapidly increasing resistance rates. Boric acid preparations are preferred in local treatment especially in resistant cases while azole formulations are the first choice in oral treatment. The only boric acid analog that was approved by FDA (Foo...

OBJECTIVE This study was planned to clarify the in vitro effect of lidocaine and bupivacaine on germ tube formation by Candida albicans isolates from cases of clinical vaginal candidiasis. METHODS Fourteen C. albicans strains (clinical vaginal isolates) were grown on Sabouraud agar for 24 h at 37 and tested as follows: 100 microl of a yeast suspension [10(5) colony forming units (CFU)/ml of p...

Salivary anticandidal activities play an important role in oral candidal infection. R. P. Santarpia et al. (Oral Microbiol. Immunol. 7:38-43, 1992) developed in vitro anticandidal assays to measure the ability of saliva to inhibit the viability of Candida albicans blastoconidia and the formation of germ tubes by C. albicans. In this report, we describe modifications of these assays for use with...

The Candida albicans vacuole has previously been observed to undergo rapid expansion during the emergence of a germ tube from a yeast cell, to occupy the majority of the parent yeast cell. Furthermore, the yeast-to-hypha switch has been implicated in the virulence of this organism. The class C vps (vacuolar protein sorting) mutants of Saccharomyces cerevisiae are defective in multiple protein d...

Encystation in Phytophthora parasitica can be divided into 3 stages. In the first, the zoospores line their peripheries with flattened vesicles and nbrillar vacuoles in preparation for encystation. In the second stage, as the zoospores round up and shed their flagella, an initial wall is produced which takes the form of the mature cyst wall in thickness, but not in density. The participation of...

Background and Purpose Ozone is an inorganic molecule with effective antimicrobial properties. Clinical treatment of ozonated water was used for the elimination of Candidaalbicans, Enterococcus faecalis, endotoxins, and biofilms from root canals. In addition, its therapeutic effects for tinea pedis, ulcers, and leishmaniasis were investigated. The purpose of the present study was to evaluate th...

The influence of kinetic patterns of Candida albicans germ tube antibodies (CAGTA) on mortality was analyzed in six intensive care units. Statistically significant lower mortality rates were found in patients with patterns of increasing CAGTA titers who had been treated with antifungal agents. Thus, antifungal treatment should be considered when CAGTA titers are increasing in critically ill pat...
