During the period from August 1997 to March 1998, two thousand samples of cultured Penaeus semisulcatus postlarvae and subadults were collected from five hatcheries and 20 growout farms distributed in three provinces along the costs of Persian Gulf and the Oman Sea. Based on growth signs, LM and TEM histopathology, Hepatopancreatic Parvo-like Virus (HPV) were identified from the samples. The HP...

The hepatopancreatic parvo-like virus (HPV) of penaeid shrimp was extracted from infected shrimp tissues, purified and subsequently characterized. The viral particles, icosahedral in shape, are 22 nm in diameter and possess a buoyant density of 1.41 g/ml. They contain ssDNA, of approximately 5 kb in size which encodes a single polypeptide of 54 kDa. On the basis of its general characteristics t...

Viral pathogens appear to exert the most significant constraints on the growth and survival of crustaceans under culture conditions. The prevalence of viral pathogens White Spot Syndrome Virus (WSSV), Hepatopancreatic Parvo Virus (HPV), Monodon Baculo Virus (MBV) and Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) in Penaeus monodon post-larvae was studied. Samples collected from ...

INTRODUCTION Persons with HIV infection frequently present with anaemia from different causes, including use of antiretroviral therapy (typically zidovudine), iron deficiency, vitamin B12 deficiency, opportunistic infections (such as mycobacterial and fungal infections), chronic disease, AIDS-associated malignancies, autoimmune haemolysis, and direct effects of HIV infection itself. Persistent ...

Feline panleukopenia virus (FPV) is a significant pathogen of cats. Rapid virus detection is critical for treatment and management, especially in populations in which spread may occur. This study investigated the ability of the SNAP Canine Parvovirus Antigen Test Kit (SNAP Parvo, IDEXX Laboratories) to detect FPV with confirmation of viral identity by polymerase chain reaction (PCR) assay and g...
