“…CNS infection by Aspergillus sp. has been recognized in a northern bottlenose whale ( Hyperoodon ampullatus ) [ 48 ], a harbor porpoise [ 49 ], three striped dolphins and a bottlenose dolphin co-infected by CeMV [ 38 , 50 ]. In this case, there was no evidence of systemic fungal infection and concomitant disease processes.…”

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.

“…The prevalence of aspergillosis in human reaches a million people and it has become a global problem (Bongomin et al, 2017). Several cases of A. fumigatus infection have reported in canine (Magro et al, 2017), cattle, horse, cat and nonhuman primates (Seyedmousavi et al, 2015), bottlenose dolphin (Cassle et al, 2016) and among the avian species (Cafarchia et al, 2014). This study elucidated that contamination of Aspergillus belonging to the "Fumigati section" in the litter and air influence to the incidence of aspergillosis.…”

Aspergillosis is the common infectious diseases in the avian species. Aspergillosis causes granulomatous lesions in the lung and upper respiratory system and rarely reported regarding its infection in the kidney. This study aims to analyse the risk factors of renal aspergillosis in the pigeon (Columba livia) and its association to aflatoxicosis and CD4+/ CD8+ depression. Twenty-dead pigeons, feed and litter randomly collected from 10-local breeders. Each breeder was asked to fill out the questionnaire. Microbiology, immuno-histopathology and detection of aflatoxin were performed on the collected specimens. The data was analysed using SPSS 16. The results revealed that the prevalence of Aspergillus belonging to the "Fumigati section" was 85% and 80% in lungs and kidneys, respectively. Moreover, the hyphae and granulomatous inflammation with minimal expression of CD4+/CD8+ are observed from pigeons kidney. This study reflected that contamination of Aspergillus belonging to the "Fumigati section" in the litter and air significantly affect the occurrence of pigeon's renal aspergillosis.

“…Marine mammal morbilliviruses as with terrestrial morbilliviruses have an affinity for lymphoid, epithelial and neuronal tissue and the pathologic findings of CeMV and PDV are similar to CDV infections of terrestrial carnivores [70,71]. Lymphotropic morbillivirus replication results in immunosuppression and often secondary opportunistic bacterial, fungal and protozoal infections which may result in highly variable lesions in more chronic morbillivirus infections [6,72,73]. Pathologic findings of infection include interstitial to bronchointerstitial pneumonia, profound widespread lymphoid depletion and syncytial cell formation [46,74].…”

Emerging infectious disease has become a serious concern that has consequences for human, animal and environmental health on a global scale. During the past two decades, it has become clear that viruses are emerging in terrestrial environments from the human-animal interface at an unprecedented rate. Thus, the understanding of complex diseases associated with emerging zoonotic pathogens and the creation and execution of strategies to deal with this issue has assumed new public health importance, requiring a One Health approach involving multiple health disciplines. Similar infectious disease trends involving emerging viruses are now being documented in aquatic ecosystems and are impacting marine mammals. As in terrestrial species, emerging viruses in marine mammals may be associated with neoplasia, epizootics and zoonotic disease and involve a complex pathogenesis involving noninfectious cofactors such as anthropogenic toxins, biotoxins, immunologic suppression and other environmental stressors. Among the viruses recently isolated from marine mammals are influenza viruses, morbilliviruses, papillomaviruses, herpesviruses, arboviruses, caliciviruses and others. Many of these emerging marine mammal viruses are associated with disease and specific pathologic findings. In other cases, the disease significance of these novel viruses is unknown and requires further research. In this report, we briefly review emerging viruses that have disease significance for marine mammals and/or public health. Novel concurrent clinicopathologic data will be presented when available broadening the understanding of disease pathogenesis. References will help provide more in-depth information. Additionally, this review has demonstrated that marine mammals may be important sentinel animals that indicate environmental health concerns and parallel emerging public health issues.
