Nematode eggs can be differentiated by optical imaging, not only in confocal but in other microscopic methods38. However, identification based on images is insufficient and time- and labour- consuming16. Selectivity can be maximized by detecting specific optical signatures in spectra of single species. 29 апр. 2020 г.
What do nematode eggs look like?
Eggs are oval, thin-shelled, and transparent. Eggs hatch to release rhabditiform larvae, which mature into filariform (infective stage) larvae.
How are nematodes identified?
Classic identification of nematodes is based on morphological and anatomical differences using microscopic image analysis. Morphological identification is among the cheaper identification methods and helps relate morphology with possible function [5].
Do nematodes have eggs?
Nematodes have well-developed reproductive systems that distinguish them as female and male nematodes. The females lay eggs, usually after fertilization by males but in some cases without fertilization. Many species lack males. Nematode eggs hatch into juveniles that resemble the adult nematodes but are smaller.
What eggs of nematodes are indistinguishable?
Hookworm egg with four blastomeres. Eggs of Ancylostoma duodenale and Necator americanus are indistinguishable (Unstained).
