AIM The present study was conducted to evaluate the effects of neem leaf extract (NLE) supplementation on immunological response and pathology of different lymphoid organs in experimentally Escherichia coli challenged broiler chickens. MATERIALS AND METHODS For this study, we procured 192-day-old broiler chicks from local hatchery and divided them into Groups A and Group B containing 96 birds...

The aim of our study was to investigate the influence of adiSalmoSOL PF dietary supplement, given for 3 days in drinking water, on selected parameters of cell-mediated (Experiment I) and humoral (Experiment II) immunity in chicken and turkey broilers. In Experiment I, birds were randomly divided into two groups of 10 birds each. Group 1 comprised control turkeys or chickens, whereas group 2 bir...

Peptide transporters 1 and 2 (PepT1 and PepT2) and peptide/histidine transporter 1 (PHT1) are all members of the proton-coupled oligopeptide transporter family, which are important for the transport of amino acids in peptide form. The PepT1 acts as a low-affinity/high-capacity transporter and PepT2 as a high-affinity/low-capacity transporter for di- and tri-peptides. The PHT1 transports di- and...

Antibiotics have been common feed additives in poultry rations as growth promoters to improve performance via reducing burden of pathogens. However, it has been increasing pressure to reduce or even eliminate antibiotic usage in poultry feed due to the negative human health issues of antibiotic resistance. Safe broiler production without medication and vaccination was conducted at present study...

Various commercial vaccines for immunization of broiler chickens against infectious bursal disease (IBD) are available, so it would be appropriate to compare the pathogenicity and immune response of chickens to these vaccines. In this study the pathogenicity and serologic response of four IBD vaccines, cloned D78®, Bursine-2®, Bursimune® and Cevac Gambo-L®, were evaluated in specific pathogen f...

Apis cerana Fabricius is endemic to most of Asia, where it has been used for honey production and pollination services for thousands of years. Since the 1980s, A. cerana has been introduced to areas outside its natural range (namely New Guinea, the Solomon Islands, and Australia), which sparked fears that it may become a pest species that could compete with, and negatively affect, native Austra...

The sugarcane borer, Diatraea saccharalis Fabricius, has great economical interest as it affects the culture and industrial use of the sugarcane. However, there are few studies concerning the internal morphology of this insect. This work aims to study morphometrically the midgut and the epithelium along their lenght, trying to characterize different regions. Midgut of last instar larvae was div...

The type specimens of the bee genus Hylaeus Fabricius, 1793 described by Ferdinand Morawitz from Asia and deposited in the Zoological Museum of the Moscow State University and in the Zoological Institute, Russian Academy of Sciences St. Petersburg, are critically reviewed. Precise information with illustrations of types for 39 taxa is provided. New synonymy is established for Hylaeus incongruus...

Because several peptides originally found in the pituitary as within the central nervous system have been localized in lymphoid tissues and because somatostatin (somatotropin-release-inhibiting hormone, SRIH) can act on cells of the immune system, we searched for this peptide in lymphoid organs. We demonstrated that SRIH mRNA exists in lymphoid tissue, albeit in smaller levels than in the periv...
