Skin Diseases Caused by Microorganisms 1) Catalase negative, Gram-positive cocci in chains with Beta-hemolytic colonies 2) Virulence factor A) Streptolysin – destroys RBC 3.
The Department of Fisheries and Oceans website will remain available until this move is complete. Nocardiosis, Fatal inflammatory bacteraemia (FIB), Focal necrosis, Multiple abscesses, Summer mortality, Pacific oyster nocardiosis (PON). Nocardia crassostreae (Actinomycete bacteria) in the Nocardia otitidiscaviarum rRNA sub-group.
West coast of North America from the Strait of Georgia, British Columbia to California, and Japan (Matsushima Bay). Infection found all year but usually associated with mortalities during the late summer and fall.
Gross Observations: Round yellow-to-green pustules up to 1 cm in diameter on the surface of the mantle, gill, adductor muscle, and heart. Tissue Imprints: Gram-positive, acid-fast, branched and beaded colonies of filamentous bacteria are observed in imprints of material from pustules.
Histology: Dense clumps of deeply staining Gram-positive, PAS-positive, branching, beaded, basophilic bacteria surrounded by an intense accumulation of haemocytes in most organs.
DNA Probes: Two sets of PCR primers and one oligonucleotide probe for detecting PON were identified by Gee and Elston (1997). Culture: After 3-5 days of growth on Brain Heart Infusion (BHI) agar plates, strains isolated from diseased Pacific oysters produced a well developed mycelium that fragmented into irregular rod-shaped forms.
Haemophilus influenzae (including Hib) is a bacterium that can cause a severe infection, occurring mostly in infants and children younger than five years of age. There are six identifiable types of Haemophilus influenzae bacteria (a through f) and other non-identifiable types (called nontypeable).
Staphylococcal Impetigo A) Superficial skin infection characterized by weeping pus production (pyoderma) 7.


Can cause endocarditis, meningitis, skin rashes, UTIs, external ear infections in swimmers, as well as corneal ulcers in contact wearers 4. Because the chickenpox lesions are itchy, many children are prone to secondary infection by S.
Ultimately causes a skin rash starting at the head the progressing to the trunk and extremities, then disappearing in the same order 6. The extent of associated mortalities has not been accurately measured but estimated at about 35% in some localities. The lesions can be reminiscent of those caused by Denman Island disease but are often larger in size.
Crassostrea gigas with lesions in the adductor muscle (A) and body wall (B) caused by Nocardia sp. Histological section of Crassostrea gigas through the edge of a lesion in the mantle with normal vesicular connective tissue in the left part of the figure and an accumulation of haemocytes around a cluster of Nocardia sp.
Histological section through a large lesion in the adductor muscle of Crassostrea gigas with nocardiosis.
Gram stained histological section through lesion containing several clusters of Nocardia sp.
Histological section through wall of intestinal tract of Crassostrea gigas with nocardiosis. One primer set amplifies a portion of the 16S rDNA template from more than one genus of mycolic acid producing bacteria, including Nocardia.
This organism belongs to Group C streptococci with regards to antigen response and is known to cause strangles.
It is thought that 100% of the population has been infected with HHV-6 by adulthood even if no symptoms have ever been seen M.
Therea€™s a vaccine that can prevent disease caused by Hib, but not the other types of H.influenzae.


Causitive agent is Propionibacterium acnes A) Digests the oil surplus resulting in intense local inflammation that can eventually burst the follicle 3.
Bacteria or spores enter damaged tissue and release exotoxins that cause necrosis of the surrounding tissues 3.
Transmitted by direct contact with respiratory secretions A) Is one of the most contagious diseases 3.
The oligonucleotide molecular probe is a pathogen specific sequence within the Nocardia specific amplicon. Primer sets and the probe can be used alone or in combination depending on the requirements for sensitivity and specificity. Pacific oyster nocardiosis: isolation of the bacterium and induction of laboratory infections.
Isolation of the bacterium causing focal necrosis (fatal inflammatory bacteremia) in Pacific oysters (Crassostrea gigas). Investigation of the relationship between the presence of a Gram-positive bacterial infection and summer mortality of the Pacific oyster, Crassostrea gigas Thunberg. Pathology and significance of fatal inflammatory bacteraemia in the Pacific oyster, Crassostrea gigas. Investigation of the stress response, summer mortality and disease resistance of oysters, Crassostrea spp. Including a lysozyme treatment within the DNeasy extraction procedure significantly increased the yield of N.
