endospore

 [en´do-spor]
1. a thick-walled body formed within the vegetative cells of certain bacteria (e.g., Bacillus, Clostridium, Sarcina) that can withstand adverse environmental conditions for prolonged periods; under favorable conditions it will germinate to form a vegetative bacterium.
2. an asexual fungal spore produced within the hyphae or cell, as in a spherule of Coccidioides immitis or in a sporangium.

en·do·spore

(en'dō-spōr),
1. A resistant body formed within the vegetative cells of some bacteria, particularly those belonging to the genera Bacillus and Clostridium.
2. A fungus spore borne within a cell or within the tubular end of a sporophore as in the spherule of Coccidioides immitis.

endospore

(ĕn′də-spôr′)
n.
1. The inner layer of the wall of a spore.
2. An asexual spore developed within a cell, as that formed by some bacteria.

endospore

a very resistant bacterial SPORE that develops intracellularly by a process called SPORULATION, from a vegetative cell.

Overall, results show that endospores of lactate-fermenting, gas-producing Clostridium spp.
botulinum can also cause infant botulism (when infants ingest the endospores and the toxin forms in the intestines in the absence of mature gastrointestinal normal flora) and wound botulism (where the bacterium multiplies in a wound and produces toxin which is absorbed into the bloodstream).
Endospores produced by these isolates become visible inside the vegetative cell after 18 h of incubation (Fig.
Definitive diagnosis of coccidioidomycosis is made when the organism is recovered from respiratory secretions, body fluids or tissue especially detecting the characteristic spherules with endospores. (9) Fungal hyphae can be recovered from specimens obtained from boundaries of old cavitary lung lesions and skin lesions.
In case of endospore formation test isolate 1, 2, 7, 12, 13, 14, 18, 19, 23, 24, 29, 33, 34, 40, 44, 45, 46, 51, 52, 56, 57, 61, 62, 68 and 69 indicated positive test, therefore confirming the rhizobacteria being Bacillus spp., as by adopting differential staining technique the endospores retained the primary dye i.e., malachite green, whereas, the vegetative cells lost the stain.
anthracis spores; therefore, the study focused on the use of brain heart infusion (BHI) (Becton Dickinson, Sparks, Maryland) and tryptic soy broth (TSB) (Becton Dickinson, Sparks, Maryland) as nutrients for the germination of Bt spores in the endospore stage.
The morphological characteristics were identified by culturing the isolate on LB agar plates and studying the shape, size, color, opacity, texture, elevation, spreading nature and margin of the colonies, followed by gram's staining, aerobic test, motility test and endospore staining.
Molecular and biochemical characterization of a highly stable bacterial laccase that occurs as a structural component of the Bacillus subtilis endospore coat.
In these cases, the spherule/ endospore form has been implicated in human disease after exposure to infected tissues or fluids.
