This study was designed to evaluate serum and milk amyloid A (SAA) as an inflammatory indicator in inflammatory diseases. Twenty clinically healthy cows and 100 cows with various inflammatory diseases were selected for this study. Blood samples were collected from the coccygeal vein of both healthy and diseased groups. Milk samples were taken from four quarters of both groups. Milk samples of f...

Infectious diseases have been implicated as a cause of high rates of adult mortality in southern sea otters. Exposure to environmental contaminants can compromise the immuno-competence of animals, predisposing them to infectious diseases. In addition to organic pollutants, certain trace elements can modulate the immune system in marine mammals. Nevertheless, reports of occurrence of trace eleme...

objective: the orange-red spectrum of  the skin of  electric yellow (labidochromis caeruleus) is  one  of  the  idealistic and  necessary  schemas sought  by  aquarists  and commercial producers. in this study, the effect of live foods meal on the skin coloration of juvenile electric yellow was examined. methods: 270 fish with an average living body weight was 0.42 ± 0.11 g, and average total l...

american foulbrood (afb) disease is caused by the sporeforming bacterium paenibacillus larvae larvae. traditional diagnosis is based on culture technique is time and laboratory work consuming. in this study with standard strain, pcr was developed by specific primers and pcr products were electrophoresed on 0.8 % agarose gel. the pcr primers were selected on the basis of the 16s rrna gene and am...

Abstract Background In the present study, detection, characterization and virulence analysis of a field collected nucleopolyhedrovirus isolated from cotton leafworm, Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) was carried out. The obtained isolate, named SpliNPV-YW, diseased S. larvae in El-Menoufia governorate, Egypt.

Effects of Daphnia magna enriched with cod liver oil (CLO) as a source of highly unsaturated fatty acid (HUFA) on growth, survival, stress resistance, and fatty acid composition of the Persian sturgeon larvae were evaluated. Daphnia enriched for three different time periods (3, 6, and 9 hours) and non-enriched Daphnia were fed to the Persian sturgeon larvae (average weight 61.6±0.4mg) during 14...

Luís, MA and, later, separated leaves from their respective branches. was obtained by means hydrodistillation dragging a steam at temperature 100ºC for 3 hours. prepared using phase inversion method. chemical constituents quantifi...

Biological control of gypsy moth ( Lymantria dispar ) was carried out in 2021 the field protective forest belts at territory State Hunting Enterprise Balchik by introducing entomopathogenic fungus Entomophaga maimaiga (Entomophthorales: Entomophthoraceae). In same year a mortality rate 26.1% pest population registered. 2022 E. and multiple nuclear polyhedrosis virus L Ld MNPV) caused collapse r...

This investigation into the natural history and behavior of 81 species of cerambycid beetles suggests that reproductive behavior is correlated with the condition of the larval host: Adults of species whose larvae attack living trees tend to show behavioral differences from those that attack dying or dead hosts. Behavioral differences among species that are associated with larval host condition ...
