Haemorrhagic nephritis and enteritis of geese (HNEG) is a fatal disease caused by goose haemorrhagic polyomavirus (GHPV). The aim of our study was to investigate a field outbreak of HNEG by pathological methods and real-time PCR assay using light upon extension (LUX PCR) with special regard to the possibility of vertical transmission. This is the first time that presence of GHPV was confirmed i...

A study was undertaken to assess the incidence of Marek’s Disease (MD) in vaccinated flocks. Blood, organ and feather follicle samples were collected from fifteen commercial layer farms in which Marek’s Disease outbreak was occurred even after vaccination with monovalent and bivalent vaccines. Blood samples were screened for serotype 1 specific132bp repeats and lymphocytes from corresponding po...

It is a very important significance to explore the bacterial typing methods rapidly, accurately and understand the genetic relation between isolates for controlling effectively the disease and preventing the dissemination and diffusion of the pathogen. The changes in the genetic material nucleotide sequences result in variation and evolution of bacteria, the development of molecular biology and...

The objective of the study was to investigate antimicrobial activity of native and reduced forms of duck lysozyme (dLz) against Salmonella enteritidis. Moreover, antimicrobial activity of dLz was compared with chicken lysozyme (cLz). The purified dLz was reduced with dithiothreitol. Free SH groups of reduced dLz were trapped with iodoacetamide. Lytic activity against Micrococcus luteus of reduc...

The duck plague vaccine (DPV) is locally produced from the Livestock Research Institute (LRI), Mohakhali, Dhaka which is used to control the duck plague viral disease in ducks in Bangladesh. Efficacy of this vaccine reports has no, so to say on ducks in Bangladesh. Three weeks old 50 Khaki Cambell Ducks were used to evaluate the induced of immune responses of duck plague vaccine during the peri...

A previous study of an avian obligate brood parasite, the black-headed duck, Heteronetta atricapilla, suggested that egg rejection by its two main hosts (two species...

Changes in the nature of the seed coat caused by gut passage are considered to be the proximate causes of changes in germination patterns. Modifications of seed coat permeability may be decisive in saline environments (e.g. Mediterranean wetlands), in which the response of the seed to osmotic stress, or its resistance to toxicity caused by some ions may be affected. We analysed how passage thro...

Composition of intramuscular lipids, phospholipid classes and phospholipid molecular species in traditional Chinese duck meat products was investigated. Free fatty acids and phospholipids were identified and quantified by gas and high performance liquid chromatography, and phospholipid molecular species were determined by mass spectrometry. The results showed that raw duck meat had high quantit...

“The Duck” is a complicated non-thermal radio system, consisting of the energetic radio pulsar B1757– 24, its surrounding pulsar wind nebula G5.27–0.90 and the adjacent supernova remnant (SNR) G5.4–1.2. PSR B1757–24 was originally claimed to be a young (≈ 15000 yr) and extreme velocity (& 1500 km s−1) pulsar which had penetrated and emerged from the shell of the associated SNR G5.4–1.2, but rec...
