| Summary: | Ovary infection (oophoritis) is among the most common diseases found in
layers between the start of egg production and during the laying phase. The incidence
of oophoritis may entend into oviduct to cause salphyngitis or vice versa. Generally,
control of oophoritis was done with antibiotics, however antibiotic treatment was
frequently improper that can support the emergence of bacterial resistance.
Oophoritis cases in Indonesia has not been widely reported, however the incidence of
decreased egg production often occurred. Oophoritis causing bacteria and antibiotic
usage for treatment is also unknown well. Therefore, this experiment was designed to
isolate and to identify the bacteria causing ovary infection in commercial layers and
to evaluate bacterial sensitivity to some antibiotics that commonly used in the field.
Nineteen samples of commercial layers that were obtained from three farms in the
region of Yogyakarta were necropsied. Samples of infected ovaries were cultured on
blood agar plates (PAD), then incubated at 370C for 18-24 hours in aerobic and
anaerobic. Gram staining and biochemical tests were performed to identify the
bacteria. After bacteria have been identified, sensitivity test was performed by disc
diffusion method of Kirby-Bauer. Bacteria that can be isolated and identified from
infected ovary were Staphylococcus aureus (29%), Escherichia coli (21%),
Staphylococcus intermedius (17%), Staphylococcus epidermidis (13%),
Streptococcus sp. (4%), Bacillus sp. (4%), Bacillus cereus (4%), Enterobacter sp.
(4%), and Klebsiella pneumonia (4%). Antibiotic sensitivity testing showed that
bacteria originated from infected ovary were sensitive to the combination of
amoxylin-clavulinic acid (88%), gentamicin (88%), enrofloxacin (71%), and
erythromycin (58%). Based on these results, it can be concluded that the most
common bacteria that can be isolated from infected ovary were Staphylococcus
aureus and Escherichia coli. Most of the bacteria isolated from infected ovary were
sensitive to the combination of of amoxylin-clavulinic acid, gentamicin,
enrofloxacin, and erythromycin, however they were resistant to colistin sulfate,
tetracycline, and penicillin. |
