| Summary: | <b> Aim:</b> This study was aimed to determination of effectiveness
of the bovine Immuneglobuline G (IgG) against Salmonella
infections caused by Salmonella Dublin, S. Typhimurium, S.
Kentucky or S. Anatum.<p>
<b> Materials and Methods:</b> Cattle were immunized with inactive
monovalent, bivalent and combined Salmonella vaccines,
three times at 21 days intervals. Immunized cattle blood
samples were collected at 10 days after last vaccination and
titres of IgG to Salmonella antigens were measured micro Serum
Agglutination Test. A total of 100 mice (total 10 vaccine
groups and each group included 10 mice) were challenged
with Salmonella strains by oral route. After challenge, IgG to
mice were administrated by oral route. Mice were observed
for occurence of morbidity and mortality for 20 days. Also,
feacal samples were analyzed to determination influence of
IgG on spread of Salmonella species by feaces.<p>
<b> Results:</b> The antibodies titres in blood of immunized cattle
were found to be high than before vaccination and controls.
The numbers of morbidity and mortality in groups of vaccine
were determined as 9 in combined vaccine (6 in S. Dublin, 2
in S. Typhimurium and 1 in S. Kentucky), 3 in bivalent vaccine
(in S. Typhimurium), and 2 in monovalent (1 in S. Anatum and
S. Kentucky). The re-isolation number of Salmonella strains
were lower from internal organs and feacal samples of mice
in all groups.<p>
<b> Conclusions:</b> In conclusion, it was observed that IgG of immunized
cattle is can be useful for protection against Salmonella
infections, but limited. |
