The main problem in the cultivation of vaname
(
Litopenaeus vannamei
)
shrimp is
disease, one of disease agent
s
is bacteria, for example genus
Vibrio
that
cause
d
vibriosis
infection
. The safe effort of
disease prevention is by using probiotics.
Bacillus
sp. D2.2 which has antibacterial and biocontrol acvities can be used as
probiotics. Application of probiotics with
Bacillus
sp. D2.2 combined with white
sweet potato prebotics containing oligosaccharides c
ould
have a beneficial effect
on the host
by stimulating microbial growth and selectively stimulating the
growth of certain bacteria in the d
igestive tract.
The aim of this research
was
to
know the resilience of vaname shrimp
that has been
given probiotic 6%
with
0%
(control) to infection bacterial of
V. alginolyticus in vivo
then histology test to
observe
muscular damage caused by infection. The results showed that the use of
probiotics
Bacillus
sp. D2.2 6%
in vivo
and histo
pato
logy test were able to
provide bet
ter shrimp resistance
against
V. alginolyticus
.

Permasalahan utama dalam
budidaya
udang
vaname
(Litopenaeus vannamei)
adalah
penyakit
, salah satu agen penyakit yaitu bakteri, misalnya genus
Vibrio
penyebab infeksi vibriosis. Upaya penanggulangan penyakit yang aman yaitu
dengan probiotik.
Bacillus
sp. D2.2 yang memiliki akvitas antibakteri dan
biokontrol dapat dimanfaatkan sebagai probiotik. Aplikasi probiotik dengan
bakteri
Bacillus
sp.
D2.2
dikombinasikan dengan prebotik ubi jalar putih yang
memiliki kandungan oligosakarida

Penelitian ini dilakukan bertujuan untuk mengetahui ketahanan udang vaname
yang diberi probiotik 6% dan 0% (kontrol) terhadap infeksi bakteri
V.
alginolyticus
secara in vivo kemudian dilakukan uji
histopatologi
untuk melihat
kerusakan jaringan
akibat infeksi. Hasil penelitan menunjukkan bahwa
penggunaan probiotik
Bacillus
sp. D2.2 6% secara
in vivo
dan uji
histopatologi
mampu memberikan ketahanan udang lebih baik terhadap infeksi
V. alginolyticus
.
