Abstract
The study was conducted for characterization of Staphylococcus sp
isolated from arthritic broiler breeder flock with antibiogram study
of identified field isolates. The study was performed in a breeder
flock. The flock consists of 7000 birds of different age groups, name
of the breed cobb 500 selected for the study. The sample were
collected from the affected birds and shifted aseptically to the
Bacteriology laboratory of the department of Microbiology Hajee
Mohammed Danesh Science and Technology University. The
samples were subjected to clinical, postmortem and microbiological
(morphological, cultural and biochemical) examination. The study
shows that infection is very high in starter and grower (58.2%) than
laying period (16.6%). The staphylococcus sp highly sensitive to
different antimicrobial agents such as 100% sensitive to
ciprofloxacin, doxycycline, penicillin, gentamicin and 70% sensitive
nitrofurantoin 60% azithromicin and resistance to cephradine,
ampicillin, amoxicillin sulfomithoxazole X Trimethoprim.
Description
The importance of Staphylococcosis in poultry sector has increased to be
a growing concern day by day throughout the world during the last
decades. Staphylocococcus aureus is a normal inhabitant of the skin and
upper respiratory tract of diseased and healthy chickens (Shiozawa et al.,
1980; Zhu et al., 1999). Several species of Staphylococcus cause
infection in poultry. Staphylococcus aureus is an important opportunist
that can cause superficial to life-threatening illnesses in a variety of
animal species. In poultry, this organism has been implicated in
osteomyelitis, synovitis, and cellulites (White DG, 2003).The
Staphylococcus sp cause a number of infection in poultry such as arthritis,
osteomyelitis, dermatitis, endocarditis, septicemia, wound infection, and
ophthalmitis. Staphylococcus infections tend to occur more frequently
during the following four periods of a breeder’s life: 0 - 2 weeks femoral
head necrosis (or bacterial chondronecrosis) are often related to egg or
hatchery contamination and minor surgeries at, 4 - 6 weeks infection hock
and stifle joints secondarily related to other infection, at 10 - 20 weeks
Infection hock and stifle joints is due to the stress of vaccination, feed
restriction and sexual maturation. Overcrowding, poor feed distribution
and insufficient feeder space exacerbate these problems.
