To catalog the diversity and abundance of halogenated organic compounds (HOCs) accumulating in high trophic marine species from southwestern Atlantic Ocean, tissue bottlenose dolphins (Tursiops truncatus) stranded or incidentally captured along coast Rio de Janeiro, Brazil, were analyzed by a nontargeted approach based on GC×GC/TOF-MS. A total 158 individual HOCs 32 different structural classes detected blubber 4 adult male T. truncatus. Nearly 90% are not routinely monitored environment....
During November-December 2017, a mass die-off of Guiana dolphins (Sotalia guianensis) began in Rio de Janeiro, Brazil. Molecular and pathologic investigations on 20 animals indicated that cetacean morbillivirus played major role. Our findings increase the knowledge health disease aspects this endangered species.
Cetacean morbillivirus (CeMV; Paramyxoviridae) is the most significant pathogen of cetaceans worldwide. The novel “multi-host” Guiana dolphin ( Sotalia guianensis; GD)-CeMV strain reported in South American waters and infects dolphins southern right whales Eubalaena australis). This study aimed to describe pathologic findings, GD-CeMV viral antigen distribution detection by RT-PCR (reverse transcriptase polymerase chain reaction), infectious comorbidities 29 that succumbed during an unusual...
This study describes the pathologic findings of 24 humpback whales (Megaptera novaeangliae) found stranded along Brazilian coast from 2004 to 2016. Eighteen (75%) animals evaluated were alive. From these, 13 died naturally on shore and five euthanized. Six at sea washed ashore. Of 24, 19 (79.2%) calves, four (16.7%) juveniles, one (4.2%) was an adult. The most probable cause stranding and/or death (CSD) determined in 23/24 (95.8%) individuals. In CSD included neonatal respiratory distress...
Abstract Since the 1980s, cetacean morbillivirus (CeMV) has caused mass mortality events worldwide. However, no epizootics had been recorded in South Atlantic, until an unusual event (UME) linked to Guiana dolphin (GD‐CeMV) began Ilha Grande Bay, southeastern Brazil, November 2017. In a five‐month period, UME spread neighboring Sepetiba Bay and accounted for death of at least 277 dolphins ( Sotalia guianensis ). Prevalence positive dolphins, as estimated from RT‐PCR diagnostics, was 92.3%...
Cetacean morbillivirus (CeMV) is a major threat to cetaceans worldwide, causing individual deaths and outbreaks of mass mortality. Based on partial sequences the viral phosphoprotein, CeMV subclassified into seven strains two distinct lineages. To date, only CeMV-1 strains, including dolphin (DMV), have been completely sequenced. The CeMV-2 lineage was first reported in Guiana dolphins (Sotalia guianensis) Brazil associated with an unusual mortality event 2017–2018. Here we provide nearly...
Rough-toothed dolphins, Steno bredanensis, are closely associated with coastal waters in the Southwestern Atlantic Ocean, increasing exposure to multiple stressors, such as chemical pollution. Persistent organic pollutants (POPs) known affect health of cetacean species. To comprehend potential impacts POPs on populations' viability, it is necessary distinguish populations and predict their risk long-term exposure. Blubbers rough-toothed dolphins (n = 28) collected along southeastern (SE)...
Cetacean morbillivirus (CeMV; Paramyxoviridae) causes epizootic and interepizootic fatalities in odontocetes mysticetes worldwide. Studies suggest there is different species-specific susceptibility to CeMV infection, with striped dolphins (Stenella coeruleoalba), bottlenose (Tursiops truncatus) Guiana (Sotalia guianensis) ranking among the most susceptible cetacean hosts. The pathogenesis of infection not fully resolved. Since no previous studies have evaluated organ-specific...
The large majority of cetacean interspecific studies report only on dolphin interactions, while interactions between odontocete and mysticete are less common. present work aims to sightings during the breeding season humpback whales (Megaptera novaeangliae) , along 370 km Bahia State, north-eastern Brazil, addressing aspects distribution behaviour. During 7 seasons (2000–2006), a total 230 research cruises were performed, in which 38 events among other cetaceans (Tursiops truncatus, Steno...
Poxviruses are emerging pathogens in cetaceans, temporarily named 'Cetaceanpoxvirus' (CePV, family Poxviridae), classified into two main lineages: CePV-1 odontocetes and CePV-2 mysticetes. Only a few studies performed the molecular detection of CePVs, based on DNA-polymerase gene and/or DNA-topoisomerase I amplification. Herein we describe new real-time PCR assay SYBR® Green primer set to detect 150 bp fragment CePV gene, also effective for conventional detection. The novel was able 5 up ×...
