Background: Chlamydia (C.) trachomatis is an obligate intracellular gram-negative pathogen affecting over 600 million people worldwide with 92 million new cases occurring globally each year. Genital C. trachomatis infection has been recognized as the most common cause of pelvic inflammatory disease leading to severe tubal damage, ectopic pregnancy, hydrosalpinx and infertility. However, the mec...

Psittacine beak and feather disease (PBFD) was diagnosed in an umbrella cockatoo (Cacatua alba) with severe feather dystrophy and loss. Electron microscopically, the intranuclear and intracytoplasmic inclusion bodies observed by light microscopy were composed of viral particles forming paracrystalline arrays, whorls, semicircles or concentric circles. Recovered viral particles from the skin and...

Intranuclear sodium, potassium, and chloride contents were measured by energy-dispersive x-ray microanalysis in freeze-fractured, freeze-dried, bulk-tumor samples taken from 10 patients suffering from invasive urogenital cancers. Human biopsies were carried out during the first diagnostic interventions before any cytostatic treatment had been applied. Pathohistological diagnosis established the...

A free-ranging adult male gray fox (Urocyon cinereoargenteus) with moderate diarrhea and thick ocular mucus discharge was examined postmortem. Microscopically, the fox had intranuclear inclusion bodies within hepatocytes. Canine adenovirus-1 was identified by polymerase chain reaction (PCR) and nucleotide sequencing. To our knowledge, this is the first report of clinical infectious canine hepat...

An 8-week-old piglet with dyspnoea, bilateral mucopurulent nasal discharge and mouth breathing was euthanased and a necropsy was performed. Apart from histological evidence of diffuse rhinitis, large intranuclear inclusion bodies, pathognomonic forporcine cytomegalovirus infection, were detected within mucous glands on the nasal turbinates. This is the first such case to be diagnosed in South A...

  Samples of formalin fixed gastrointestinal organs of three month ostrich chicks were submitted to the department of Pathology, Razi Vaccine and Serum Research Institute. Histologically hepatitis and pancreatitis with large eosinophilic intra nuclear inclusion bodies were prominent in hepatic and pancreatic cells. These inclusions were suspected as adenovirus inclusion body hepatitis (IBH) in ...
