Detection of morulae in the peripheral blood smear can provides a rapid diagnostic clue for HGA. However, morulae are most likely to be found during the first week of illness and disappear within 24–72 h after starting doxycycline [1].

morula, solid mass of blastomeres resulting from a number of cleavages of a zygote, or fertilized egg. Its name derives from its resemblance to a mulberry (Latin: morum). A morula is usually produced in those species the eggs of which contain little yolk and, consequently, undergo complete cleavage.

Morulae are cytoplasmic membrane-bound vacuoles with irregular edges that contain hundreds to thousands of gram-negative bacteria. You might find these chapters and articles relevant to this topic.

2023年8月3日 · An early stage in post-fertilization development when cells have rapidly mitotically divided to produce a solid mass of cells (16 or more) with a “mulberry” appearance is called the morula stage. The morula stage is the final stage prior to the formation of a fluid-filled cavity called the blastocoel cavity.

2019年2月14日 · This case shows that the detection of morulae in a blood smear can be helpful in the diagnosis of HGA, especially in the acute phase of illness, prior to empirical antibiotic administration. Keywords: Diagnosis; Human granulocytic anaplasmosis; Morulae.

2023年11月21日 · A morula is a microscopic ball or cluster of cells formed through cell division very early in the embryonic development that occurs after fertilization but before the blastocyst stage. As the...

Ehrlichiae are small, obligately intracellular Gram-negative bacteria. The bacteria multiply within cytoplasmic vacuoles derived from early endosomes and form intracytoplasmic microcolonies known as morulae (from the Latin ‘morus’ for mulberry owing to the microscopic appearance of the microcolony by Romanovsky stain) (Figs 109.3, 109.4) [34].

Morulae (plural of morula) are spherical masses of cells that form in the early stages of embryonic development, following the fertilization of an ovum (egg cell). Each morula is a solid cluster of cells, known as blastomeres , that results from the initial cell …

2019年10月7日 · Morulae of A. phagocytophilum are commonly detected in neutrophils of most clinically affected dogs and so infection is usually confirmed during performance of a complete blood cell count.
