Clostridioides difficile is a Gram-positive, spore-forming, toxin-producing anaerobe, and an important nosocomial pathogen. Due to the strictly anaerobic nature of the vegetative form, spores are the main morphotype of infection and transmission of the disease. Spore formation and their subsequent germination play critical roles in C. difficile infection (CDI) progress. Under suitable condition...

In this study, aerial parts of Lippia citriodora Kunth were harvested at three phenological stages (i.e. vegetative, full flowering and fruit set). The essential oil isolated by hydro distillation for 3 h using a Clevenger-type apparatus and the oil was analyzed by GC and GC-MS. The yields of oils (w/w%) in different stages was in the order of: full flowering (0.9%), vegetative (0.48%) and frui...

The organization of microtubules in germinated pollen of the conifer Picea abies (Norway spruce, Pinaceae) was examined using primarily confocal microscopy. Pollination in conifers differs from angiosperms in the number of mitotic divisions between the microspore and the sperm and in the growth rate of the pollen tube. These differences may be orchestrated by the cytoskeleton, and this study fi...

Endocarditis is rarely reported in sheep and information presented for ovine endocarditis is based mostly on comparative findings in the cattle. Infective vegetative endocarditis of the right heart was diagnosed in a 3-year-old fat-tailed ram. Clinical findings included tachycardia, marked brisket edema, jugular veins distention and pulsation and pale mucous membranes. Hematologic abnormality i...

The vegetative state may develop suddenly (as a consequence of traumatic or non-traumatic brain injury, such as hypoxia or anoxia; infection; or haemorrhage) or gradually (in the course of a neurodegenerative disorder, such as Alzheimer’s disease). Although uncommon, the condition is perplexing because there is an apparent dissociation between the two cardinal elements of consciousness: awarene...
