The lesion had a mass effect, deforming and displacing the brainstem to the right. The mean P50 value of harbor porpoise blood at 5% CO2 (PCO2≈35.7 mmHg) was 29.8 mmHg, which increased to 36.2 mmHg at 9% CO2 and decreased to 19.3 mmHg at 1% CO2. In animal tissue, Aspergillus usually develops without producing conidial heads (Seyedmousavi et al., 2015) limiting the characterization to Aspergillus –like hyphae. Harbor porpoises are active divers that exchange O2 and CO2 with the environment during a fast single breath upon surfacing. doi: 10.1053/jcpa.2001.0547, Jepson, P. D., Baker, J. R., Kuiken, T., Simpson, V. R., Kennedy, S., and Bennett, P. M. (2000). P50 is somewhat smaller) than in terrestrial mammals of similar size (Schmidt-Nielsen, 1997). System - Female . doi: 10.1159/000293601, Prahl, S., Jepson, P. D., Sanchez-Hanke, M., Deaville, R., and Siebert, U. 28, 729–734. Histopathologic and immunocytochemical studies of distemper in harbor porpoises. Release of NO activity from deoxygenating RBCs during a dive may, however, help O2 delivery to tissues such as the heart and the brain that remain perfused. 127, 137–144. However, this does not explain the difference between harbor porpoise and rabbit, because P50 of the Hb was similar in the two species. IJsseldijk, L. L., and ten Doeschate, M. T. I. Animals that were rehabilitated following live stranding or those that were given any medication prior to euthanasia, were not included in this study. Table 2. 131, 201–207. The mechanism is not applicable in deep-diving seals that exhale before diving, and where the alveoli collapse. Organ. (A) Granular, irregular plaques in the bronchi of case #18. For terms and use, please refer to our Terms and Conditions Culture negative samples were analyzed using a real-time PCR to detect Aspergillus DNA at the Department of Medical Microbiology of Radboudumc. From an epidemiologic perspective, aspergillosis in free-ranging delphinids is often occurring with co-infection of dolphin morbillivirus (DMV; Cassle et al., 2016; Terio et al., 2018), but for other species, including the harbor porpoise, morbillivirus infections are reported only infrequently (Kennedy et al., 1991; De Swart et al., 1995, Müller et al., 2000). 124, 102–114. Microbiol. This value is similar to the PCl value in human RBCs at 37°C (Jensen and Brahm, 1995) and to PCl values observed in a number of ectothermic animals at their respective preferred temperatures (Jensen et al., 2001). Aspergillosis in free-living cetaceans has often been reported in co-infection with morbillivirus (e.g., Domingo et al., 1992). However, infections with Scedosporium spp. J. Comp. Reproductive organs were assessed grossly in order to make a final differentiation between juveniles and adults. Experiments on individual blood samples were completed within 48 h. For comparative purposes, blood from pig (Sus scofa domesticus) was obtained from a local slaughterhouse (Danish Crown, Odense) and blood from sheep (Ovis aries) was acquired from the Biomedical Laboratory, University of Southern Denmark. Most animals were in a good nutritional condition (NCC1-2, n = 8), four presented a moderate nutritional condition (NCC3-4) and four porpoises a poor nutritive condition (NCC5) and the remaining two harbor porpoises were emaciated (NCC6; Table 1). Pathol. 160, 3115–3120. (2013). Fungal identification was based on colony characteristics of isolates and microscopic morphology on lactophenol cotton blue mount.

Agents Dis. De Swart, R., Harder, T., Ross, P., Vos, H., and Osterhaus, A. Figure 2. Interestingly, the animal with obstructive bronchitis (#18) had no macroscopic or histologic evidence of pulmonary parasites. Pathol. The Company of Biologists is the first not-for-profit publisher to commit to this approach.

We thank Genevieve Desportes and Angela Fago for useful discussions, and the staff at Fjord and Belt and Dolfinarium Harderwijk for their help during blood sampling. 122, 171–183. Login via your The drawn curve is an exponential fit to the data (R2=0.9994). The true plasma buffer value primarily reflects the buffering capacity of Hb. The buffer value of separated plasma reflects the buffering properties of plasma proteins. Culture was performed in 17/18 of the cases and was positive in 10/17. Secondary findings, including the presence and severity of parasites, are given in Tables 2,3.

Carcasses were transported to Utrecht University (UU), Faculty of Veterinary Medicine, Division of Pathology for immediate necropsy, or temporally stored at −20°C prior to further investigations. At present, no information is available on the rate of erythrocyte anion exchange in diving mammals. Monitoring of fungal loads in seabird rehabilitation centers with comparisons to natural seabird environments in northern California. 5E), in agreement with the stoichiometry for the complex autocatalytic oxidation of oxyHb by nitrite (Kosaka and Tyuma, 1987): At intermediate SO2 values (as occurs in vivo), nitrite can react with both deoxyHb and oxyHb, but the deoxyHb reaction producing NO (reaction 1) was clearly favored, as seen from the steeper decline in [deoxyHb] with time (i.e.
5D). Along the southern North Sea, harbor porpoise (Phocoena phocoena) strandings increased significantly since 2005 and necropsies to determine causes of death have been conducted since 2008. Sci. In most cases, there were also cross sections of parasites present, notably not in the case with occlusive bronchitis (#18). Microbiol. Diving marine mammals can experience large decreases in local temperature in the peripheral circulation and may also reduce core temperature during dives.

The temperature was 25°C. Presumably this difference is a direct consequence of the specific anatomy and physiology of cetaceans.
Aspergillus alabamensis, a new clinically relevant species in the section Terrei. 2), but the correlation failed to be significant at the P<0.05 level (P=0.087). One of these animals (#15) live stranded and during respiration, asymmetry of the blowhole musculature and a partial hemiplegia of the blowhole was observed (Supplementary Video). practice, diagnostic laboratories, reproductive and pathological laboratories,
