Q

Renibacterium Salmonimarum cause —

A

bacterial kidney disease (BKD)
pin-pount hemorrage
granulomas throughout spleen and kidney

gram + bacteria

18
Q

host species for Renibacterium Salmonimarum

A

Salmonid species are the primary hosts, although the disease has been induced in non-salmonid species.

bacterial kidney disease
gram + bacteria

19
Q

—- is very harmful. Induces haemolytic, proteolytic, exotoxin, catalase and DNAse activities.

A

Renibacterium Salmonimarum

gram + bacteria

bacterial kidney disease (BKD)

20
Q

virulent factor for renibacterium salmonimarum

A

p57- promotes intracellular invasion of leucocytes and inducing immunosuppression.

vibriosis
lesions and external hemorrhage

gram - bacteria

Q

25
Piscirickettsia salmonis cause
Piscirickettsiosis white/yellow systemic ulcers, kidney necrosis, anemia | gram - nonmotile bacterium, non-encapsulated
26
how to get Piscirickettsia salmonis
Enters through gills and skin and or infected preys -Horizontal and vertical transmission | salmon disease gram - bacteria
27
Piscirickettsia salmonis uses --- as vectors. Will infect --- and spread and evade host
isopod macrophages | gram - bacteria
28
why does kidney injury cause anemia in fish
no bone marrow blood products made in the kidney
29
Infectious haematopoietic necrosis virus cause
thick trailing fecal cast hemorrage necrosis
30
what animals are infected by IHNV
Infectious haematopoietic necrosis virus salmon fry little fish
31
treatement for IHNV
No commercial vaccines available. Immunization of fish with IHNV induces neutralizing antibodies.
32
the "ebola" of fish viruses
Infectious haematopoietic necrosis virus IHNV
33
Viral Haemorrhagic Septicaemia Virus (VHSV) cause
giant eyes hemorrage in swim bladder and fatty tissue septicemia kidney necrosis- anemia
34
--- causes marked kidney necrosis. Loss of haemopoietic cells. Deadly especially in infected fry.
VHSV
35
treatment for VHSV
-No commercial vaccines available. Immunization of fish with VHSV induces neutralizing antibodies | Viral Haemorrhagic Septicaemia Virus
36
Koi herpesvirus causes
-lethargy, -erratic swimming behaviour -increased mucus production -haemorrhaging within the liver -gill necrosis
37
oomycetes
water molds fungal disease
38
--- usually infects fish that are already diseased (secondary infections) and/or fish that are immunosuppressed.
-Fungi
39
Many fungi, especially the ---- induce lymphocytopenia, and impairment of the haematopoietic organs
oomycetes ## Footnote fungus
40
treatment for oomycetes
malachite green, 0.5% NaCl. ## Footnote fungi
