Ultrastructure of Cowdry type A inclusions Semantic Scholar

Cowdry bodies are eosinophilic or basophilic [1] nuclear inclusions composed of nucleic acid and protein seen in cells infected with Herpes simplex virus, Varicella-zoster virus, and Cytomegalovirus. They are named after Edmund Cowdry. There are two types of intranuclear Cowdry bodies: Type A (as seen in herpes simplex and VZV) [2] Gross description. According to macroscopic appearance, HSV esophagitis is divided into 3 types ( Medicine (Baltimore) 2016;95:e3187 ): Type I: small, punched out lesions with raised margins usually coated with yellowish exudate. Type II: small, punched out lesions but no raised margins or exudate.

Type A: acidophilic material of droplet-like masses surrounded by clear halos within nuclei., seen in gingivostomatitis and conjunctivitis caused by Herpes simplex virus and also chicken pox caused by varicella zoster. 3 Type B intranuclear eosinophilic without any nuclear change, seen in infection with poliovirus and CMV. History. When present in herpes virus infection and present with the other nuclear changes of this infection they are called Cowdry Type A inclusions. Cowdry Type B inclusions are associated with other infections such as poliovirus and do not have the other nuclear changes of herpes infection. Unlike most other viruses involving the lung, CMV-infected cells have both intracytoplasmic and intranuclear inclusions. The intranuclear inclusion is large and commonly surrounded by a halo and a prominent rim of marginated host chromatin, providing the classic "owl's eye" appearance (Cowdry type A inclusion). There are two types: Type A (in herpes infection and yellow fever) and Type-B (in infection with polio and adenovirus) Cowdry type-A inclusion bodies appear as droplet-like masses of acidophilic materials surrounded by clear halos within nuclei, with margination of chromatin on the nuclear membrane. Type-B bodies are not associated with any.

(A) Cowdry type B inclusion of Herpes simplex virus (HSV). There is multinucleation in this infected cell, molding of these nuclei, and chromatin margination beneath the nuclear membrane (Papanicolaou stain, 400×). (B) Cowdry type A inclusion of HSV. Note the characteristic eosinophilic intranuclear inclusion surrounded by a clear zone in.

Viruses Herpes simplex virus Histopathologically, necrobiotic tubular cells are classified into inclusion-bearing cells of three types: 1) "smudge cells," 2) "Cowdry A" intranuclear inclusion cells including intranuclear. Herpes simplex virus infections may be caused by two virus genotypes: herpes simplex virus type 1 and herpes simplex virus type 2 ().Worldwide seroprevalence is high, with antibodies detectable in over 90% of the population. Of these cases, approx. 60% are caused by HSV-1.The most common infections are labial and genital herpes, which present with painful ulcerations. Bottom right, a classic Cowdry type A inclusion body is seen in the nucleus of a glial cell at the center of the field (case 10). Note the peripheralizadon of the chromatin at the nuclear membrane and the clear halo surrounding the central eosinophilic, proteinaceous inclusion. (Hematoxylin-eosin stain, x 1,000.)

Here, we report Cowdry type A inclusion bodies (CAIB) in the pancreas as a diagnostic histopathological feature found in adult Nile tilapia naturally infected with TiPV. This type of inclusion body has been well-known as a histopathological landmark for the diagnosis of other parvoviral infections in shrimp and terrestrial species. Cowdry type A Cowdry type A inclusion bodies are seen with herpes simplex virus (HSV) and varicella-zoster virus infections. Cowdry type B Cowdry type B bodies are seen in poliovirus infections. Negri bodies Negri bodies are seen in rabies. Warthin Finkeldey bodies Warthin Finkeldey bodies are seen in measles. Henderson-Patterson bodies
