Aim: To find out the organisms causing
endometritis in cattle and to determine their in
vitro sensitivity to various antibiotics.
Materials and Methods: Thirty uterine
secretion samples, 9 from Holstein Friesian and 21
from Jersey cows were collected in and around
Namakkal district of Tamil Nadu from clinical
cases of endometritis. The bacteria isolated both
aerobically and anaerobically from endometritis
showed the characteristic colony, were gram
stained and confirmed by standard biochemical
tests. The in vitro antibiotic sensitivity
test with different antibiotic discs were carried
out.
Results: Out of 30 samples, 25
contained different strains of bacteria and 5 were
found bacteriologically sterile. Different species
of bacteria isolated from these samples were,
Escherichia coli (36.66%), Klebsiella spp
(30%), Proteus spp (13.33%), Pseudomonas
aeruginosa (6.66%), Clostridium spp
(3.33%). The in vitro antibiotic
sensitivity test indicated that the highest number
of isolates (64%) were sensitive to Ceftriaxone,
followed by Gentamicin, Enrofloxacin and
Chlortetracycline (32%). Chloramphenicol showed
sensitivity in minimum number (8%) of isolates.
Conclusion: This study revealed that the
bacteria E. coli and Klebisella spp
are more commonly isolated in endometritis in cows
and the drug Ceftriaxone is highly effective.
