A Review: Factors Affecting Outbreaks of Saprolegniosis on Aquatic Animals
Get PDFIn this paper, we review the current knowledge regarding factors affecting the
outbreaks of saprolegniosis. Saprolegniosis is a serious disease which can
cause significant economic losses in aquaculture. Oomycetes are considered
to be responsible for the disease. Outbreaks of saprolegniosis occur when
equilibrium between pathogenic oomycetes and host resistance is disturbed.
This may be the result of an increase in numbers or virulence of the zoospores
of oomycetes in the water, or an increase in the susceptibility of the host. The
presence of oomycetes zoospores in the environment is regarded as one of
the most important causes of saprolegniosis. However, important differences
have been found between plant and animal pathogenic oomycetes and appear
to be related not only to tactic responses to environment, but also to infection
strategies to a host. In addition, fish are more susceptible to infection by
pathogenic oomycetes when physically injured, stressed or infected.
Furthermore, water environmental factors, such as temperature, salinity, and
microorganisms, should be carefully considered since they play a key role in
the outbreaks of saprolegniosis
Recovery of Listonella anguillarum from Diseased Pufferfish (Takifugu rubripes) in China
Get PDFIn May 2016, there was a disease outbreak among pufferfish (Takifugu
rubripes) in a marine farm in Tianjin municipality, with the cumulative
mortality rate reaching 45% within 7 days from the beginning of the
outbreak. The main symptoms of the disease were abdominal and anal
swelling of the diseased fish. Significant damage was also observed
histopathologically in the intestine, liver, and kidney. The strain H008 was
isolated from diseased kidneys, and the challenge test revealed that the same
disease was diagnosed in pufferfish which suffered similarly high mortality
rates. Using physiological biochemical tests combined with 16S rDNA
sequence analysis, the strain was identified as Listonella anguillarum.
Antimicrobial susceptibility tests showed that H008 was resistant to 10 of 15
antimicrobial agents tested. To the best of our knowledge, this is the first
report of L. anguillarum causing disease in pufferfish
Providencia alcalifaciens: a Causal Agent of Red Leg Disease in Freshwater-Cultured Whiteleg Shrimp Penaeus vannamei
Get PDFRed leg disease causes significant economic losses in whiteleg shrimp Penaeus vannamei. Yet only scarce information is available on Providencia alcalifaciens as a bacterial pathogen of this disease. In this study, a virulent strain, temporarily named P3, was isolated from diseased freshwater-cultured P. vannamei suffering from red leg disease, identified phenotypically and molecularly as P. alcalifaciens. A phylogenetic tree was constructed to examine the taxonomic position and relatedness of isolate P3 to other P. alcalifaciens isolates. When screened against a range of common veterinary antibiotics, isolate P3 exhibited susceptibility to aminoglycosides and quinolones antibiotics in aquaculture. To the best of our knowledge, this is the first report of P. alcalifaciens as a causal agent of red leg disease in freshwater-cultured P. vannamei
Efficacy of Tricaine Methanesulfonate (MS-222) as an Anesthetic Agent for Short-term Anesthesia in Juvenile Yellow Perch (Perca flavescens)
Get PDFThe present study was conducted to assess an optimal dose of tricaine methansulfonate (MS-222) for rapid anesthesia and recovery in juvenile Yellow perch Perca flavescens. Yellow perch (≈7.0 g/fish) exposed to increasing concentrations of MS-222 (100, 150, 200, 250 and 300 mg/L) showed significant (P<0.05) decreased anesthetic induction and increased recovery time with increasing MS-222 dose. Among the doses tested, the 250 mg/L MS-222 dose showed the shortest anesthetic induction and recovery times. Blood glucose and hematocrit levels were significantly (P<0.05) lower in juvenile yellow perch exposed to the 250 mg/L MS-222 dose than the other MS-222 doses tested. Juvenile yellow perch (about 9.7 g/fish) exposed to 250/mg MS-222 combined with bicarbonate buffer at three ratios (w/w: 1:0.5, 1:1 and 1:2) showed significantly (P<0.05) reduced anesthesia induction and recovery times. The shortest times of anesthesia induction and recover were observed in treatments using the 1:1 MS-222 to buffer ratio. Analysis on serum biochemical parameters (e.g., osmolality, glucose, albumin, calcium, alanine transaminase, total protein and calcium) showed that use of sodium bicarbonate with MS-222 did not have any significant effect on the above measurements compared with those determined in fish exposed to MS-222 only. Anesthesia induction time and recovery time of yellow perch were significantly affected by body sizes. These results suggest that a brief exposure to a 250 mg/L MS-222: sodium bicarbonate dose may be optimal for minimizing handling disturbance in juvenile yellow perch
