A survey was conducted to study clinical signs, gross and histopathological lesions in pigeons with naturally occurring Newcastle disease. For this purpose, 30 pigeon lofts were visited. Among these, 14 lofts showed clinical signs of Newcastle disease, including mainly greenish white mucoid diarrhoea and nervous signs with high morbidity and mortality. Postmortem examination of affected birds s...

Aluminum is present in very small amounts in living organisms but abundant in the environment. A growing literature links with the biochemistry of aluminum and also with a series of diseases in chronic renal failure patients on treatment with hemodialysis. The initial description of potential aluminum toxicity in renal failure patients relates to description of dialysis encephalopathy syndr...

Newcastle disease is an economically important disease of poultry for which vaccination is applied as a preventive measure in many countries. Nevertheless, outbreaks have been reported in vaccinated populations. This suggests that either the vaccination coverage level is too low or that vaccination does not provide perfect immunity, allowing the virus to spread in partially vaccinated populatio...

Newcastle disease virus (NDV)-expressing avian influenza virus (AIV) hemagglutinin (HA) of subtype H5 was constructed by reverse genetics. A cloned full-length copy of the genome of the lentogenic NDV strain Clone 30 was used for insertion of the ORF encoding the HA of the highly pathogenic AIV isolate A/chicken/Italy/8/98 (H5N2) in the intergenic region between the NDV fusion and hemagglutinin...

Since 2002, following its introduction, the lineage 5d Newcastle disease virus (so-called Goose paramyxovirus - GPMV) strain has caused numerous disease outbreaks among commercial and backyard poultry in South Africa, raising questions about the ability of commercially available Newcastle disease vaccines to fully protect poultry against the strain. This study aimed to determine whether there a...

An epidemic of Newcastle disease occurred in turkeys of Southern Utah in the late fall of I965. Several workers in intimate contact with the turkeys at the processing plant developed a follicular conjunctivitis subsequently identified as due to Newcastle disease virus. The typical clinical findings and rise in haemagglutinin-inhibition titre indicated that the infection was acquired from the tu...

BACKGROUND Nowadays natural products such as pure compounds and plant extract scan provide unlimited opportunities for new antiviral drugs. Newcastle disease virus (NDV) is one of the most important viral diseases in poultry industry. Vaccination could provide protection against NDV outbreaks, but it is not sufficient because infections by NDVs have remained frequent around the world. OBJECTI...
