Introduction of a Newcastle disease virus challenge strain (sub-genotype VII.1.1) isolated in Iran.

Newcastle disease virus (NDV) sub-genotype VII.1.1 is the most common circulating NDV in Iran.

First detection and characterisation of sub-genotype XIII.2.1 Newcastle disease virus isolated from backyard chickens in Iran.

Background: Newcastle disease (ND) is an economically significant poultry disease worldwide. During field surveillance for ND in 2010 in Iran, a backyard chicken flock showed clinical signs of ND with 100% mortality.

Objectives: We aimed to characterise genetically, biologically and epidemiologically an exotic virulent ND virus (NDV) detected in Iran.

The First Occurrence of Hepatitis-Hydropericardium Syndrome in Iran and Effective Applied Control Measures in the Affected Commercial Broiler Flock.

Fowl adenoviruses cause three economically important diseases in broiler chicken flocks: hepatitis-hydropericardium syndrome (HHS), inclusion body hepatitis (IBH), and adenoviral gizzard erosion. IBH has not been considered a serious threat in northeast Iran since the last decade, because no major effect on flock performance has been noticed along with a low mortality rate. During this period, all the sporadic IBH outbreaks have also been investigated for HHS without finding any confirmed case.

Cytotoxic Effect of Alcoholic Extracts on MCF-7, HeLa, and A2780 Cell Lines.

Conventional cancer treatments are costly and have different serious side effects for patients. Natural herbal treatments are widely accepted among people because of their minimal side effects, although there is little scientific knowledge about them. One of these remedies utilizes the root of that has been used for years in Iran to treat different chronic genital diseases.

prediction of linear B-cell epitopes for S1 protein of two Iranian 793/B isolates and their changes after 90 serial passaging.

Neutralizing, serotype-specific, and hemagglutination-inhibiting antibodies against infectious bronchitis virus (IBV) are induced by epitopes in the S1 protein. Most changes in the virus genome due to mutation and recombination during serial passaging in embryonated chicken eggs occur in the S1 gene. In the current study, we tried to predict the potential linear B-cell epitopes of the S1 subunit of two Iranian 793/B isolates and then we analyzed their changes at passage level 90 due to mutations at this passage level.
