“…The differences between the current observations and those made by Christensen et al (1996) may be due to the genetic difference between the strains of bacteria used as well as the chickens used in the study. The most probable reason for the discrepancies on the peak bacterial counts between the current experiment and that of Waihenya et al (2002) would be the fact that the current results were influenced by the presence of different ecotypes.…”

“…In that study, a similar trend where bacteria were being cleared after the peak counts was observed. Other studies (Christensen et al ., 1996;Waihenya et al ., 2002) have shown peak counts to occur on day 7 and 6, respectively, contrasting the current results. However, the clearance of the bacteria from the two organs followed a trend similar to that obtained in the current experiment.…”

“…On the other hand, the Mbeya ecotype peaked on day 6 after infection and the Pemba ecotype on day 14 after infection. It was seen, therefore, that between ecotypes some were in agreement with the previous studies (Christensen et al ., 1996;Mdegela et al ., 2002;Waihenya et al ., 2002). The results may hence suggest the existence of different host response mechanisms between the different local chicken ecotypes studied.…”

“…Aloe vera is one of the most well-known herbal medicines with various properties such as healing, anti-inflammatory, anti-oxidative, anti-diabetic and immunomodulatory effects as well as antibacterial, antifungal and antiparasitic properties (Waihenya et al 2002;Boudreau and Beland 2006). Studies suggest that chemical composition of Aloe plant, to a large extent, depends on the species analysed.…”

The purpose of the present research is to study the effects of different levels of Aloe vera gel on microflora population, humoral and cellular immune response, and relative weight of lymphoid organs compared to the effects brought about by antibiotic. The groups included the control group (basal diet) as well as three groups with different levels of Aloe vera gel (added to basal diet at 1.5%, 2% and 2.5%), and finally a group with basal diet supplemented by 15 ppm virginiamycin antibiotic. Regarding ileum microflora, the increase in Aloe vera gel in the feed resulted in significant reduction in the number of E. coli colonies and significant increase in the number of Lactobacillus colonies compared to the control and antibiotic groups. As far as humoral immunity is concerned, Newcastle disease virus antibody titre on the 24th and 38th day was the highest in 2.5% and 2% Aloe vera gel groups, respectively. In addition, sheep red blood cells antibody titre reached its highest level in the 2.5% Aloe vera gel group on the days 24, 28, 34 and 38. The differences among the groups regarding sheep red blood cells antibody titre were significant on the days 24, 28 and 34, while no significant differences were observed on the 38th day. Regarding the cellular immunity, the highest response was obtained by injecting phytohemagglutinin-P and the highest relative weight of spleen and bursa of Fabricius was found in the 2.5% Aloe vera gel group. The findings of the study suggest reduction in number of E. coli colonies and increase in number of Lactobacillus colonies as a result of increased Aloe vera gel in the feed. Furthermore, the 2.5% Aloe vera gel group resulted in significantly higher levels of humoral and cellular immunity, as well as relatively greater weight of lymphoid organs, which suggests that Aloe vera gel can be a proper replacement for the virginiamycin antibiotic.

For prevention of atrophic rhinitis of swine by Bordetella bronchiseptica and fowl typhoid by Salmonella gallinarum, bacterial strains showing antimicrobial activity against those pathogenic bacteria were isolated from various samples collected at animal farms. Among 372 bacterial isolates strain TK3 showed the highest antibacterial activity against both pathogens, and was identified as Bacillus amyloliquefaciens by 16S rRNA gene sequence analysis. B. amyloliquefaciens TK3 could inhibit growth of both pathogens by secretion of antibacterial compounds such as siderophore, rhamnolipid and antimicrobial peptide. Production radius of siderophore on Chrome azurol S agar plate by strain TK3 was 0.53 cm after 14 days of incubation, and concentration of siderophore in King's B medium was 1.06 mmol/ml. It also secreted 82.4 mg/L of rhamnolipid, and antimicrobial peptide that completely inhibited growth of both pathogens at concentration of 30 μl/ml in LB medium.
