Dietary Curcuma longa enhances resistance against Eimeria maxima and Eimeria tenella infections in chickens.
The effects of dietary supplementation with an organic extract of Curcuma longa on systemic and local immune responses to experimental Eimeria maxima and Eimeria tenella infections were evaluated in commercial broiler chickens. Dietary supplementation with C. longa enhanced coccidiosis resistance as demonstrated by increased BW gains, reduced fecal oocyst shedding, and decreased gut lesions com...
متن کاملevaluating the resistance of eimeria spp. field isolates to anticoccidial drugs using three different indices.
background: in this study, the presence of resistance to diclazuril, amprolium+ethopabate and salinomycin, representing some of the commonest anticoccidials in iran’s poultry industry, against three mixed eimeria field isolates were investigated. methods: three eimeria field isolates, collected from typical broiler farms in iran, were propagated once, inoculated to 480 broilers, comprising 30 c...
متن کاملResistance, susceptibility, and immunity to Eimeria tenella in major histocompatibility (B) complex congenic lines.
The major histocompatibility (B) complex influence on resistance, susceptibility, and immunity to Eimeria tenella was examined in UCD B complex congenic chicken lines. In Experiment 1, 6-wk-old chicks from 12 UCD congenic lines were weighed and assigned to either challenge or control groups. The challenge group received a dose of 10,000 E. tenella oocysts. Response to challenge was evaluated by...
متن کاملAntimicrobial Resistance Pattern of Stenotrophomonas maltophilia Isolates from a Tertiary Care Setting in Rawalpindi, Pakistan
Introduction: Stenotrophomonas maltophilia is intrinsically resistant to many antimicrobials. Like Pseudomonas spp., this bacterium has a remarkable ability to cause infections, particularly in the respiratory and urinary tracts. This study aims to determine the antimicrobial resistance pattern of S. maltophilia isolates collected from a tertiary care setting and frequency of multi, extensively...
متن کاملIdentification of common immunodominant antigens of Eimeria tenella, Eimeria acervulina and Eimeria maxima by immunoproteomic analysis
Clinical chicken coccidiosis is mostly caused by simultaneous infection of several Eimeria species, and host immunity against Eimeria is species-specific. It is urgent to identify common immunodominant antigen of Eimeria for developing multivalent anticoccidial vaccines. In this study, sporozoite proteins of Eimeria tenella, Eimeria acervulina and Eimeria maxima were analyzed by two-dimensional...
