Abstract Understanding the population structure and genetic diversity of green turtles is crucial for effective conservation. This study investigated occurrence, composition, potential origins ( Chelonia mydas ) in Potiguar Basin, northeastern Brazil, based on stranding data from 2010 to 2019. Analysis revealed that 87.36% consisted juveniles, primarily females with a curved carapace length (CCL) between 30 59.9 cm. Genetic analysis mtDNA control region (481 bp, n = 39) eight haplotypes,...

Abstract Fibropapillomatosis (FP) can be an important conservation threat to green sea turtles ( Chelonia mydas ) due its widespread distribution and complex aetiology. Thus, understanding the impacts of FP in turtle populations is a research priority towards efforts. The body condition index (BCI), based on straight carapace length (SCL) mass (BM), accurate indicator body-nutritional that used routine health evaluations. This study aimed compare BCI FP-free (N = 369) FP-affected 518) from...

Antimicrobial resistance is an ancient natural phenomenon increasingly pressured by anthropogenic activities. Escherichia coli has been used as markers of environmental contamination and human-related activity. Seabirds may be bioindicators clinically relevant bacterial pathogens their antimicrobial genes, including extended-spectrum-beta-lactamase (ESBL) and/or plasmid-encoded AmpC (pAmpC), in anthropized remote areas. We evaluated cloacal swabs 20 wild magnificent frigatebirds ( Fregata...

The knowledge regarding infectious agents affecting wildlife is crucial for species’ conservation. We hypothesized that herpesviruses are present in wild Neotropical carnivores. Herein, we used DNA polymerase and glycoprotein B broad‐spectrum PCRs to molecularly survey the presence of spleen and/or lung samples 53 carnivores Brazil, comprising families Canidae, Felidae, Mustelidae, Procyonidae. percentage PCR‐positives was 28.3% (15/53). An alphaherpesvirus found a river otter ( Lontra...

Abstract A captive loggerhead turtle ( Caretta caretta ) of unknown sex, 3 years age, presented with bilateral mucoid secretions, severe chemosis, conjunctival hyperemia, and globe retraction. The animal was evaluated ophthalmologically systemically, hematological, microbiological, cytological biopsy samples were collected for complementary diagnosis. histopathological examination showed amphophilic intranuclear inclusions associated inflammatory infiltrate. diagnosis Chelonid...

Abstract Chelonid alphaherpesvirus 5 (ChHV5) has been consistently associated with fibropapillomatosis (FP), a neoplastic disease that affects sea turtles globally. The DNA of ChHV5 detected in cutaneous and noncutaneous tissues (e.g., lung) green Chelonia mydas (FP+) without (FP−) clinical signs FP, indicating persistent infection. Previously published custom primer pairs were used to amplify the fragments unique long (UL) partial genes (UL30 UL18) through end-point PCR from tumors (n =...

Fibropapillomatosis (FP) is an infectious disease caused by Chelonid alphaherpesvirus 5 (ChHV5). Nevertheless, its clinical manifestations are considered multifactorial. Due to relevance, FP currently monitored in sea turtle populations the United States, Australia, Caribbean, and Brazil. Between 2000 2020, TAMAR Project/ Project Foundation analyzed prevalence of nine states oceanic islands along Brazilian coast, including Fernando de Noronha Archipelago (FNA), a historically FP-free area.

Abstract Seabirds are one of the most threatened avian groups. Viruses, including herpesvirus, represent considerable threats to marine avifauna. Herein, our goal was survey herpesvirus in Procellariiformes that stranded Brazil between June and July 2021. We analyzed 12 Cory's shearwaters ( Calonectris borealis ), two Great Shearwaters Ardenna gravis , syn.

Polyomaviruses (PyVs) are small double-stranded DNA viruses able to infect species across all vertebrate taxa. In cetaceans, PyVs have been reported only in short-beaked common dolphin (Delphinus delphis), bottlenose (Tursiops truncatus) and killer whale (Orcinus orca). Herein, we surveyed PyV 119 cetaceans (29 mysticetes 90 odontocetes) stranded along the Brazilian coast, from 2002 2022, comprising 18 species. extracted lungs was tested using a nested PCR targeting major capsid protein gene...
