Table 3 Significant diagnoses from bacterial infections in respiratory, lymphoid, central nervous, and integumentary systems

PP041215

Aeromonas sp.

Pneumonia, necrotizing, suppurative, locally extensive, acute marked

Aggregates of bacteria with neutrophils. Aeromonas sp. cultured from lung

PP110329

Actinobacillus delphinicola

Bronchopneumonia, multifocal, acute, marked

Alveoli filled with neutrophils. Part of these neutrophils are degenerate and apparently transformed into globules of dark blue chromatin (as seen with some bacterial infections: nuclear streaming). Actinobacillus delphinicola cultured from lung and lung draining lymph node

PP070221

Actinobacillus delphinicola

Brucella sp.

Bronchopneumonia, multifocal, suppurative, acute, moderate

Bacteria observed with fibrin, macrophages, and neutrophils in lung lesions. Actinobacillus delphinicola cultured from lung draining lymph node, Brucella sp. cultured form lung

PP110711

Brucella ceti

1. Pneumonia, pyogranulomatous, locally extensive, chronic, marked

Marked inflammatory reaction with many neutrophils and macrophages. TBLN sample yielded culture of Brucella ceti

2. Lymphadenitis multifocal subacute to chronic marked

Subcapsular infiltration with neutrophils (TBLN), increase of lymphocytes in medulla and vacuolated macrophages in cortex (PSLN)

Brucella ceti cultured from both lymph nodes

PP120906.3

Enterococcus faecalis

Interstitial pneumonia, suppurative, histiocytic, locally extensive, chronic, moderate

Inflammatory reaction typical for bacterial infection. Enterococcus faecalis cultured form lung sample

PP030405

Escherichia coli; Pseudomonas aeruginosa; Streptococcus sp.

Pneumonia, pyogranulomatous, multifocal, chronic, marked

Histologic association of bacteria with lesion. Escherichia coli; Pseudomonas aeruginosa; Streptococcus sp. cultured from lung sample

PP061122.2

Escherichia coli

1. Bronchopneumonia, suppurative, multifocal, subacute to chronic, marked

2. Myositis, suppurative, multifocal, acute, moderate

3. Fasciitis, suppurative, focal, acute, moderate

Histologic association of bacteria with lesion. Escherichia coli cultured from sample

PP121031

Salmonella sp. (host adapted group B Salmonella)

Bronchopneumonia, pyogranulomatous, necrotizing, multifocal, chronic, moderate

Histologic association of bacteria with lesion. Salmonella sp. cultured from sample

PP120906.2

Streptococcus dysgalactiae

1. Interstitial pneumonia, suppurative, diffuse, acute, moderate

2. Hepatic abscesses, multiple, marked

3. Arthritis, suppurative, diffuse, acute, marked

4. Sepsis

Inflammatory reaction typical of bacterial infection (suppurative interstitial pneumonia, multiple marked hepatic abscesses, observation of strings of bacteria in joint capsule with associated inflammatory relation) Streptococus dysgalactiae cultured from ear abscess, liver abscess, lung, liver, spleen, kidney, trachea-bronchial lymph node, pre-scapular lymph node, adrenal and uterus

PP121130

Shewanella putrefaciens

Enterococcus faecalis

Gram negative non-fermenter

Dermatitis, pyogranulomatous, multifocal, chronic, marked, with epidermal hyperplasia, keratin pearls, and bacterial infection

Many aggregates of small coccobacilli mixed with many neutrophils and macrophages observed in the epidermis

PP111219

Escherichia coli Stenotrophomonas maltophilia

Bronchopneumonia, haemorrhagic, suppurative, diffuse, acute, marked, associated with bacterial infection

Histologic association of bacteria with lesion. Salmonella sp. cultured from sample

PP050502

Shewanella putrefaciens

Enterococcus faecalis

Streptococcus sp.

Dermatitis, multifocal, suppurative, superficial, acute, moderate

Histologic association of bacteria with lesion and bacteria cultured from sample

PP060524

Clostridium perfringens

1. Cerebellum: panencephalitis, pyogranulomatous, haemorrhagic, necrotizing, locally extensive, marked associated with fungal hyphae (Aspergillus sp.) and mixed bacterial infection

2. Otitis media purulent subacute to chronic diffuse marked

Bacteria observed centrally in pyogranulomas in meninges and cultured from middle ear and brain samples
