Pathologic findings and causes of death of stranded cetaceans in the Canary Islands (2006-2012)

This study describes the pathologic findings and most probable causes of death (CD) of 224 cetaceans stranded along the coastline of the Canary Islands (Spain) over a 7-year period, 2006–2012. Most probable CD, grouped as pathologic categories (PCs), was identified in 208/224 (92.8%) examined animals. Within natural PCs, those associated with good nutritional status represented 70/208 (33.6%), whereas, those associated with significant loss of nutritional status represented 49/208 (23.5%). Fatal intra- and interspecific traumatic interactions were 37/208 (17.8%). Vessel collisions included 24/208 (11.5%). Neonatal/perinatal pathology involved 13/208 (6.2%). Fatal interaction with fishing activities comprised 10/208 (4.8%). Within anthropogenic PCs, foreign body-associated pathology represented 5/208 (2.4%). A CD could not be determined in 16/208 (7.7%) cases. Natural PCs were dominated by infectious and parasitic disease processes. Herein, our results suggest that between 2006 and 2012, in the Canary Islands, direct human activity appeared responsible for 19% of cetaceans deaths, while natural pathologies accounted for 81%. These results, integrating novel findings and published reports, aid in delineating baseline knowledge on cetacean pathology and may be of value to rehabilitators, caregivers, diagnosticians and future conservation policies.

First Report of Wohlfahrtiimonaschitiniclastica Isolation from a Patient with Cellulitis in the United States

et al. 2015

We report the first documented isolation of Wohlfahrtiimonas chitiniclastica from a human in the United States. Initially misidentified as Acinetobacter lwoffii by Vitek-2, the isolate was subsequently identified as W. chitiniclastica by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and 16S rRNA gene sequencing. While the clinical significance of the isolate in this case is unclear, it highlights the superior performance of MALDI-TOF MS for bacterial identification. CASE REPORTA 26-year-old morbidly obese male courier worker was admitted with worsening right leg swelling and draining ulcers. He had developed lymphedema of the right leg during the preceding year after undergoing surgical correction of a right lower extremity varus deformity. A few weeks prior to the current admission, he had noticed right leg ulcers draining yellowish green serosanguineous fluid. On admission, he was afebrile and his white blood cell count was 11,100/l. He was found to have right lower extremity cellulitis.A swab was collected from the right leg and sent to the microbiology laboratory for wound cultures. The sample was inoculated onto blood, chocolate, and MacConkey agars and incubated under aerobic conditions at 37°C. Gram staining revealed many Gram-negative bacilli and moderate Gram-positive cocci. Four different organisms were isolated from the swab after growth. Microbial identification of each isolate was performed by using routine biochemical tests, including automated identification by the Vitek 2 system (bioMérieux, Marcy l'Etoile, France). The organisms were identified as Proteus vulgaris, Klebsiella pneumoniae, Acinetobacter lwoffii, and Staphylococcus aureus. The isolates were subsequently analyzed in triplicate by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) (RUO version 3.1, Bruker Biotyper; Bruker Daltonics, Bremen, Germany). Of note, the isolate identified as A. lwoffii by the Vitek 2 system was identified by MALDI-TOF MS as Wohlfahrtiimonas chitiniclastica, with identification log (score) values of 2.253, 2.296, and 2.229.

“…The northernmost region from which a case has been reported is Estonia, where a 64-year-old man with chronic foot gangrene was coinfected with W. chitiniclastica and Myroides odoratimimus ( 8 ). Cases from the United States include septicemia in a deer in Michigan ( 9 ) and a leg wound infection in a 26-year-old man in New York ( 10 ).…”
