present investigation was carried out to identify dna polymorphism of il-2rγ and chb6 genes. sixty five birds belonging to the indigenous chicken of himachal pradesh were utilized. good quality dna samples were subjected to pcr-rflp analysis using chicken specific primers. overnight restriction enzyme digestion was carried out at 37°c with iu hph i and pvu ii for il-2rγ and chb6 genes, respecti...

canine distemper virus (cdv) creates a very contagious viral multi-systemic canine distemper (cd) disease that affects most species of carnivora order. the virus is genetically heterogeneous, particularly in section of the hemagglutinin (h) gene. sequence analysis of the h gene can be useful to investigate distinction of various lineages related to geographical distribution and cdv molecular ep...

Streptococcus suis 2 (SS2) has evolved into a highly invasive pathogen responsible for two large-scale outbreaks of streptococcal toxic shock-like syndrome (STSLS) in China. Excessive inflammation stimulated by SS2 is considered a hallmark of STSLS, even it also plays important roles in other clinical symptoms of SS2-related disease, including meningitis, septicemia, and sudden death. However, ...

While conventional LDL-C, HDL-C, and triglyceride measurements reflect aggregate properties of plasma lipoprotein fractions, NMR-based measurements more accurately reflect lipoprotein particle concentrations according to class (LDL, HDL, and VLDL) and particle size (small, medium, and large). The concentrations of these lipoprotein sub-fractions may be related to risk of cardiovascular disease ...

Streptococcus suis serotype 2 (SS2) is an important zoonotic agent in swine and humans. Anti-phagocytosis and survival in phagocytic cells and whole blood is essential for bacteria to be pathogenic. In this study, the host specificity determinant specificity subunit (coded by hsdS) of the Type I Restriction-Modification system and two peptidoglycan-binding proteins (coded by lysM and lysM', res...

objective: aflatoxin is important in the food industry, in animal husbandry and the medical area; there are enormous negative economic impacts due to this toxin. numerous studies have researched extracts and plant compounds with the intent to reduce the growth of aflatoxin-producing organisms, inhibit toxin production and suppress the major toxin encoded genes (i.e., aflr) in these organisms. l...

abstract: fifteen non-aflatoxigenic strains of aspergillus flavus, represent a wide range of geographic regions of iran (six provinces include fars, ardebil, guilan, golestan, kerman and semnan) and vegetative compatibility groups (vcgs), were collected from corn (zea mays l.), peanut (arachis hypogaea l.) and pistachio (pistachia vera l.) soils and kernels, were screened for the presence of af...

it is now agreed that 10-25% of infertile men with azoospermia have submicroscopic deletions of the y chromosome long ann (yq), consistent with the proposed location of the azoospermia locus (azf) in yq 11.23. however, it is not known whether yq microdeletions are unique to men with azoospermia or whether they are also observed in infertile men with less severe defects of spermatogenesis (oligo...

background & objective: streptococcosis is one of the bacterial infections in fish, especially rainbow trout which infects brain and nervous systems of fish and is caused by s. iniae . estimation of the impact of disease prevalence by s. iniae in fish farming in some countries is reported about 100 million dollars per year. some of the most effective proteins in pathogenicity of these bacteria ...

the ovine melatonin receptor 1a (mtnr1a) and aromatase (cyp19) genes were structurally characterized and the association between their variants and reproductive and growth traits was studied in kurdi sheep at kurdi sheep breeding station located in shirvan, iran. the genomic dna was extracted by guanidine thiocyanate-silica gel method. polymerase chain reaction was carried out to amplify 824 bp...
