Abstract
A
s
tudy was conducted to find out the incidence of various mastitis causing organism in cattle of organized dairy farm.
Out of total 44 clinical mastitis samples 13.64% were found to have fungal mastitis and 77.26% were found to have bacterial mastitis.
The yeast and yeast like fungi isolated were
candida spp
. and
Aspergillus spp
. Good hygiene, sanitation and managemental practices
of farm animal and workers and judicious use of antibiotics will lowerincidence of bovine mycotic mastitis.

1 Introduction
Mastitis is caused by multi etiological agent includes
bacteria, mycoplasmas, viruses, fungi and algae
(Kivaria and Noordhnizen, 2007; Wellenberg et al.,
2002). According to literature data, fungal infections
account for 2%–13% of all cases of mastitis in cows
(Krukowski et al., 2006; Krukowski, et al
.,
2000).
Sometimes, their incidence is much higher or they are
enzootic. It is widely prevalent in organized as well as
un organized dairy herds and associated with a
significant loss of milk yield resulting in increased
costs of production and treatment, which also
deteriorated quality of milk and milk products (Arshad
et al., 1998). Amongst fungal mastitis
Candida
is the
most common species isolated from cases of mastitis
in bovines (Radostitis, 1995). Many a times mycotic
mastitis is unnoticed by clinician in first attempt of
treatment and administration of antibiotics may
aggravate fungal mastitis as some of the antibiotics
like penicillin and tetracycline act as a source of
nitrogen for various species of fungi (Meek, 1981).
There for treatment of fungal mastitis is a challenge as
many of these fungi do not respond to the antibiotics
rather they use some of the antibiotic like tetracycline
as their source of energy (Tarfarosh and Purohit, 2008).
Due to this reason most of the mastitis cases remains
incurable and source of infection for other adjoining
animals.
Keeping in view, present work is undertaken to
evaluate a prevalence of fungal mastitis in cattle at
organised dairy farm (Cattle Breeding Farm, JAU,
Junagadh).
2 Result
Out of total 44 samples examined, 6 samples yielded
fungal agents, 34 samples were positive for bacteria
and the remaining 4 were negative for fungal as well
as bacterial agents (Table 1).
In this study, the incidence of fungal agents in clinical
cases of mastitis was 13.64% (6).Out of 6 isolates of
fungi, 2 isolates yielded smooth white or yellowish,
cottony colonies having resemblance with
Candida
spp.
(Figure 1). Upon microscopic examination these
isolates showed oval shaped budding cells and were
tentatively identified as
Candida spp.
Remaining 4
isolates revealed rapid growing colonies with greenish
or black pigmentation, showing resemblance with
