Prevalence and aetiology of coccidiosis in broiler chickens in Bejaia province, Algeria.

The prevalence of coccidiosis was determined and Eimeria species were identified in farms at different locations in the Bejaia region, Algeria. The study was conducted from February to December 2016. Unvaccinated birds were selected randomly.

Determination of the optimal time of vaccination against infectious bursal disease virus (Gumboro) in Algeria.

This study was conducted to determine the effect of maternally derived antibody (MDA) on live vaccine against infectious bursal disease. A total of 140 chicks selected from vaccinated parent stock were used in this investigation. In a preset vaccination schedule, blood samples were collected to check for the actual effect.

Modulatory effects of non-steroidal anti-inflammatory drugs on the luminol and lucigenin amplified chemiluminescence of equine neutrophils.

The purpose of this study was to explore the potential modulation of equine neutrophil oxidative burst by a series of classical NSAIDs which was subsequently monitored by the luminol or lucigenin-enhanced chemiluminescence (CL) technique. A significant dose-dependent inhibition of the luminol CL was observed with the majority of investigated drugs. This inhibition was very significant for phenylbutazone and Indomethacin; while for aspirin, a higher concentration is required.

Additive action of royal jelly and honey against Staphylococcus aureus.

Four varieties of honey and one variety of freshly reaped royal jelly (RJ) were used to evaluate their additive action against Staphylococcus aureus (ATCC 29523). In a first step honey and RJ were used separately to determine their minimum inhibitory concentration (MIC) against the tested strain. In a second step, lower concentrations of honey than the MIC were added to lower concentrations of RJ than the MIC and then incorporated into media to determine the minimum additive inhibitory concentration.

Synergistic action of starch and honey against Aspergillus niger in correlation with Diastase Number.

To evaluate the synergistic action of starch on the antifungal activity of honey, a comparative method of adding honey with and without starch to culture media was used. Aspergillus niger was used to determine the minimum inhibitory concentration (MIC) of five varieties of honey. In the second step, lower concentrations of honey than the MIC were incubated with a set of concentrations of starch and then added to media to determine the minimum synergistic inhibitory concentration (MSIC).
