Furthermore, the capacity of this strain to produce slime on Congo Red Agar, biofilm formation on polystyrene plate and hydrophobicity are reported. In addition, the modification of the membrane fatty acids profiles has been studied.

The obtained results show that the strain survival is strongly influenced by acidity. Indeed, the stressed and unstressed strains became biofilm positive after acid stress. A significant increase in the hydrophobicity percentage compared to the values found under normal conditions, is also noticed.

Through the analysis of the complete sequences of internal gene cassette together with previously characterized HA and NA genes we found three different genotypes amongst five completely sequenced viruses. Two viruses possessed a completely H1avN1 genotype (40%) and belonged to the H1avN1 lineage, which is prevalent in European swine populations. The other three viruses have arisen through the reassortment of the genes of H1avN1 and H1N1pdm09 lineages. In one sample we detected coinfection with viruses of H3N2 subtype with genes of H1avN1, H1N1pdm09 and A/swine/Gent/1/1984-like H3N2 lineages that presents a potential environment for the generation of a triple reassortant virus. The presence of the H1N1pdm09 origin M gene in this sample implies the potential risk of the introduction of these viruses into the human population.

For this purpose, 19 Holstein-Friesian dairy cows were allocated into concrete and rubber mat groups. Swab samples were taken from the teat ends to determine the bacterial counts causing environmental mastitis. Milk samples were collected from a composite of all four quarters to determine the SCC. Instantaneous sampling method was utilized to observe the behavioral activities of cows. Cows were visually evaluated to determine the udder cleanliness score. Independent samples t-test was utilized in the statistical analysis of the obtained data. Coliform (P<0.05), Escherichia coli, and Klebsiella spp. (P<0.01) counts of the swab samples taken from the cows housed on concrete flooring were significantly higher than rubber mat group. However, no statistically significant differences were found between groups in terms of total bacteria, Streptococcus spp., and Enterobacteriaceae counts. The SCC on samples taken from cows kept on concrete surface were significantly higher (P<0,05) than that of animals housed on rubber mat. Furthermore, cows in the rubber mat group were determined to be significantly cleaner (P<0.05) than those in concrete group. It was also determined that the cows housed on rubber mat spent significantly longer time for lying behavior (P<0.05), which is a significant indicator of animal comfort. The time spent for standing without eating was considerably higher (P<0.01) in concrete group. In addition, the times spent for eating was significantly lower (P<0.01) in the concrete group.

The anticoccidial drugs, synbiotic and probiotic can partially prevent morphological changes in any three segments of small intestine in broiler chicken with coccidiosis.
