To develop a live vaccine strain against fowl typhoid and paratyphoid caused by Salmonella serovar Gallinarum biovar Gallinarum (Salmonella Gallinarum) and Salmonella serovar Enteritidis (Salmonella Enteritidis), respectively, several nalidixic acid resistant mutants were selected from lipopolysaccharide (LPS) rough strains of Salmonella Gallinarum that escaped from fatal infection of a LPS-bin...

Recombinant outer membrane protein H (rOmpH) is a potential fowl cholera vaccine candidate. The present study was aimed at developing rOmpH formulations for intranasal administration. The rOmpH was purified and formulated with either Escherichia coli enterotoxin B (LTB) or CpG oligodeoxynucleotides (ODN) as an adjuvant. Antibody responses in chickens intranasally immunized with rOmpH in combina...

A strain each of mumps and Newcastle disease virus and five strains of influenza virus were found to be capable of removing all the receptors for this group of viruses from fowl red cells. Five virus strains were tested for their capacity to inactivate the virus hemagglutinin of human plasma and of egg white. In the case of egg white all strains including mumps and Newcastle disease virus inact...

Objectives: Comparative histological studies of pineal gland of man and fowl has been made to observe structural differences if any between these two species. Background: Some works have been done sporadically on laboratory animals and on birds and also in human correlating with other parameters. In this investigation an approach has been made to observe the cellular organization of the pineal ...

The members of the genus Eimeria infect a wide range of vertebrate hosts, such as swine, cattle, goats, sheep, rabbits, turkeys and chickens. It is now generally accepted that seven Eimeria species are recognised to parasitize the intestinal tract of the domestic fowl (Gallus gallus domesticus). Of all the Eimeria species that infect domestic fowl, Eimeria maxima is the most immunogenic species...

The fatty acid composition of the intramuscular lipids of cattle, pigs and birds were determined relative to breed and feeding regime. The cattle included Yellow Cattle, Hereford and Japanese Black; pigs included Wild-boar, Touyuens and Yorkshires; the birds were Wild-birds, Jungle-fowl and broilers. The pen fed animals such as Japanese Black cattle and Yorkshire pigs had a higher amounts of ol...

Differential scanning calorimetry (DSC) was applied to elucidate the thermal behavior of fowl feather keratins (barbs, rachis, and calamus) with different morphological features. The DSC curves exhibited a clear and relatively large endothermic peak at about 110-160 degrees C in the wet condition. A considerable decrease in transition temperature with urea and its helical structure content esti...

The isolation of a Gram-negative bacillus from the nasal exudate of fowl experimentally infected with an uncomplicated coryza is reported in the preceding paper. ~ The introduction of this organism into the palatine cleft of normal fowl was regularly followed by an inflammation of the upper air passages with a discharge from the nares. I t was of importance to determine whether any infectious a...
