The reported that the Streptococcus sps, E.coli, Klebsiella spp,

The microbial load in
collected milk samples was analyzed to be Staphylococcus aureus, E.coli,
Bacillus and Pseudomonas. Among 12 milk samples 9 shows positive for Staphylococcus
aureus, 4 positive for E.coli, one sample positive for both Bacillus and
Pseudomonas. The prevalence of micro oraganisms in the present study was
reported as Staphylococcus aureus(75%), E.coli(33.3%) , Bacillus(8.23%) and
Pseudomonas(8.23%)respectively. Similar results with be Staphylococcus
(coagulase positive Staphylococcus spp. (44.76%) and coagulase negative
Staphylococcus spp. (22.86%)) was the predominant organism isolated from
mastitis milk samples followed by Streptococcus spp., E.coli, Bacillus spp.,
Cornyebacterium spp. and Pseudomonas spp. Ajuwape etal (2005) reported the
similar kind results with coagulase-negative Staphylococcus (50.9%) as
predominant organism followed by Escherichia coli (15.1%), Streptococcus spp.
(9.4%), Bacillus cereus (7.5%), Mannhiemia haemolytica (5.7%), Corynebacterium
spp. (5.7%) and Klebsiella pneumoniae (5.7%).

The other major pathogen
responsible for mastits was E.coli with 33.3% these results are in similar with
the results of Ameh and Tari (2000) , while sree priya et al (2017) reported
the prevalence of E.coli with 50% incidence in goat mastitis. Radostitis et
al., 2000 reported that the Streptococcus sps, E.coli, Klebsiella spp,
Citrobacter spp, Enterobacter spp, Pseudomonas spp, Serratia spp, Proteus spp. As
environmental pathogens. The Bacillus cereus found in one sample in the present
study the prevalence of this organism also reported in the studies of Ajuwape
etal (2005) with Bacillus cereus (7.5%).

On analysis it reveals
that Staphylococcus aureus plays predominat role for mastitis in ewes followed
by E.coli. even the other organisms like Bacillus and Pseudomonas were detected
the Staphylococcus aerus and E.coli plays important role. The mono microbial
infection with Staphylococcus aeurus and E.coli and mixed infection with both
these organisms and mixed with Bacillus and Pseudomonas also observed in the present
study.  The incidence of mono microbial
infection with staphylococcus spp observed in 7 quarters , E.coli in 1 quarter
while the mixed infection was observed with both Staphylococcus and E.coli in 2
quarters and with staphylococcus, bacillus and Pseudomonas in 1 quarter. Sree
priya et al (2017) reported the mixed infection of Staphylococcus with E.coli
and Klebisiella. The Staphylococcus sps and E.coli were isolated from the gangrenous
mastitis cases in goat by Pal et al (2011). The mono bacterial infection predominates
mixed infection in goat mastitis. Sarker and Samad (2011) also reported the
predominance of mono bacterial infection (76.27%) over the mixed microbial infection
(16.95%).

One of the major causes
of mastitis in goat farming was found to be poor management with low hygiene at
the farm as well as animals itself. The unhygienic condition of farm and
animals results in mastitis with coliforms (Radostitis et al., 2000).

The Staphylococcus sps were the predominate as like in other mastitis
cases in other animals while the presence of coliforms is majorly due to
improper management in farms as well as unclean animals. One of the predisposing
factor for mastitis in goat were found to be overcrowding which results in
scope of spreading microorganisms from infected animals to healthy animals even
from infectef quarter to healthy quarter in same animal.
