A Proposed New Strain of Avian Picornavirus in Broiler Chicken from Brazil

An experimental study on broiler chicken co-infected with the specimens containing avian influenza (H9 subtype) and infectious bronchitis (4/91 strain) viruses

This experimental study was carried out to induce a co-infection of H9 AIV and IBV with inoculumsprepared from tracheal scrubbed epithelium tissues in natural co-infected birds to rule out the effect of fieldundesired environmental conditions and also other infectious causative agents. Eighty 1-day-old broilerswere randomly divided into four equal groups. At 21 days of age, three test groups we...

Phylogenetic Study Based on the Gene of Attachment Protein (G) Avian Metapneumovirus from Broiler Breeder farm in Iran, 2013

Background and Aims: Avian metapneumovirus (aMPV) is RNA virus responsible for upper respiratory disease in poultry which is usually accompanied by secondary bacterial infections. In Iran, some molecular and serological studies indicated that aMPV infection occurred in commercial poultry industry. Materials and Methods: In this study aMPV was molecularly identified and characterized in an affec...

Efficacy of Thermostable Newcastle Disease Virus Strain I-2 in Broiler Chickens Challenged with Highly Virulent Newcastle Virus

Newcastle disease (ND) is a major threat to poultry industry production throughout developing countries. The Newcastle disease viruses (NDVs) infecting industrialized and indigenous poultry in Iran are velogenic strains and responsible for the frequent outbreaks of ND in poultry farms even in vaccinated flocks causing serious economic losses in the commercial and indigenous poultry. However, va...

Evaluation of the Pathogenicity of A/Chicken/Iran/ZMT-173/99 H9N2 Strain of Avian Influenza Virus in Serologically Mycoplasma Galisepticum Positive and Negative Broiler Chickens

The Effect of Water Pressure and Chlorine Concentration on Microbiological Characteristics of Spray Washed Broiler Carcasses

The objective of this study was to evaluate the efficiency of water pressure and concentration of dichloromethane after the evisceration system under the fecal decontamination of chicken carcasse  surfaces with and without apparent contamination. From a total of  322 carcasses, 50% were intentionally added chicken droppings in an area of more  than 2 cm2 and the rest of carcasses were kept with...
