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

From: Clinical, pathological, and laboratory diagnoses of diseases of harbour porpoises (Phocoena phocoena), live stranded on the Dutch and adjacent coasts from 2003 to 2016

Erasmus code numbera Bacterium Lesion Observation which links bacterium to lesion
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
  1. aErasmus code numbers are made of two letters as acronym for genus and species (here Phocoena phocoena) and six numbers indicating year, month and day of necropsy. The suffix T indicates the animal was treated with fenbendazole (an antiparasiticum) during rehabilitation.
