Comparison of Oxytetracycline and Sulfamethazine Effects Over Root Elongation in Selected Wild and Crop Plants Commonly Present in the Mediterranean Cropland and Pasture Scenarios.

Fertilization with animal manure and sewage sludge, and the use of sewage water for irrigation, can lead to high antimicrobial concentrations in agricultural soils. Once in soil, antimicrobials can exert direct and indirect toxic effects on plants by misbalancing plant-microbe symbiotic relationships. We performed germination tests to determine the optimum germination conditions of 24 plant species (10 crop and 14 wild species).

Environmental contamination by veterinary medicinal products and their implications in the conservation of the endangered Pyrenean Capercaillie (Tetrao urogallus aquitanicus).

The endangered Pyrenean Capercaillie (Tetrao urogallus aquitanicus) inhabits perennial forests of the Pyrenees (Spain, France and Andorre). Feces of domestic animals (e.g.

Polyomavirus surveillance in cetaceans of Brazil: first detection of polyomavirus in Guiana dolphins ().

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 (), common bottlenose dolphin () and killer whale (). Herein, we surveyed PyV in 119 cetaceans (29 mysticetes and 90 odontocetes) stranded along the Brazilian coast, from 2002 to 2022, comprising 18 species.

ESBL-Producing Enterobacterales at the Human-Domestic Animal-Wildlife Interface: A One Health Approach to Antimicrobial Resistance in Piauí, Northeastern Brazil.

The use, misuse, and overuse of antimicrobials is one of the main public health threats of the 21st century. We investigated the risk factor of the presence of extended-spectrum, cephalosporin-resistant Enterobacterales in feces of non-domestic and domestic birds and other domestic animals in Piauí State, northeast Brazil. We collected a total of 387 cloacal and rectal swab samples of free-living birds, domestic birds, and domestic mammals in five municipalities: Amarante, Água Branca, Lagoa Alegre, Parnaíba, and Teresina.

Molecular Detection and Characterization of Mycoplasma spp. in Marine Mammals, Brazil.

Mycoplasma spp. are wall-less bacteria able to infect mammals and are classified as hemotropic (hemoplasma) and nonhemotropic. In aquatic mammals, hemoplasma have been reported in California sea lions (Zalophus californianus) and river dolphins (Inia spp.

Herpesvirus, Flavivirus, and Coronavirus Surveillance in Magnificent Frigatebirds (Fregata magnificens), Alcatrazes Archipelago, Southeastern Brazil.

We surveyed the presence of herpesvirus, flavivirus, and coronavirus in 20 Magnificent Frigatebirds (Fregata magnificens) from the protected Alcatrazes Island, Alcatrazes archipelago, Brazil. One adult female was positive for herpesvirus (5% occurrence; 95% confidence interval -5.5 to 15.

Short-Finned Pilot Whale Strandings Associated with Pilot Whale Morbillivirus, Brazil.

Cetacean morbillivirus (CeMV) causes illness and death in cetaceans worldwide; the CeMV strains circulating in the Southern Hemisphere are poorly known. We detected a pilot whale CeMV strain in 3 short-finned pilot whales (Globicephala macrorhynchus) stranded in Brazil during July-October 2020. Our results confirm this virus circulates in this species.

Herpesvirus and adenovirus surveillance in threatened wild West Indian (Trichechus manatus) and Amazonian manatees (Trichechus inunguis), Brazil.

African (Trichechus senegalenses), West Indian (T. manatus), WIM)], and the Amazonian manatees (T. inunguis, AMM).

World Health Organization critical priority clone ST648 in magnificent frigatebird () of an uninhabited insular environment.

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

Erysipelas in a stranded common bottlenose dolphin: first report in a South American odontocete.

Erysipelas is a zoonotic disease caused by Erysipelothrix rhusiopathiae. In cetaceans, this disease has two main clinical forms: a cutaneous one, grossly characterized by rhomboid lesions, and a septicemic and often fatal form. Erysipelas is considered an important cause of morbidity and mortality in captive cetaceans; however, information in free-ranging cetaceans is limited.

Adenovirus surveillance in wild carnivores from Brazil.

Landscape transformation favors the spread of new pathogens that can be shared between domestic and wild animals. Certain adenoviruses (e.g.

Myeloid and histiocytic sarcomas in subantarctic fur seals Arctocephalus tropicalis, Brazil.

Histopathological and immunohistochemical methods were used to diagnose round cell tumors in 2 subantarctic fur seals Arctocephalus tropicalis with marked anemia. Although wild-born, both individuals were placed under human care while juveniles in a Brazilian aquarium. Both pinnipeds were PCR tested for herpesvirus, and 1 was infected with otariid gammaherpesvirus 5 (OtHV-5), previously described in a subantarctic fur seal stranded in Brazil.

Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli survey in wild seabirds at a pristine atoll in the southern Atlantic Ocean, Brazil: First report of the O25b-ST131 clone harboring bla.

Antimicrobial resistance is among the most serious public health threats of the 21st century, with great impact in terms of One Health. Among antimicrobial resistant bacteria (ARB), extended-spectrum ß-lactamase (ESBL)-producing Escherichia coli (ESBL-EC) represent major challenges to human healthcare. Wild birds have been commonly used as environmental bioindicators of ESBL-EC.

Novel alphaherpesvirus in a wild South American sea lion (Otaria byronia) with pulmonary tuberculosis.

In 2017, an adult male South American sea lion (Otaria byronia), presenting emaciation and a cervical abscess, stranded alive in Florianópolis, southern Brazil. The animal was directed to a rehabilitation center, dying a few days later. On necropsy, the main gross findings were necrotizing lymphadenitis of the right prescapular lymph node and nodular bronchopneumonia.

Nutritional Secondary Hyperparathyroidism and Fibrous Osteodystrophy in a Captive African Penguin () Similar to Osteomalacia in Poultry.

A 9-yr-old female black-footed African penguin () was presented for necropsy after a history of reproductive abnormalities, paresis of limbs, weakness, and sudden death. Postmortem examination revealed soft keel, collapsed rib cage with beading of the ribs, and bilateral parathyroid enlargement. Classic histologic lesions of fibrous osteodystrophy with osteomalacia were observed in the ribs, vertebrae, and to a lesser extent in the femur and tibiotarsus associated with hyperplasia of parathyroid glands.

Case report of respiratory aspergillosis and candidiasis in wild Magellanic penguins (Spheniscus magellanicus), Brazil.

Magellanic penguins (Spheniscus magellanicus) migrate to the continental shelf of southern-southeastern Brazil during austral winter. Stranded penguins are directed to rehabilitation centers, where they occasionally develop fungal diseases. Aspergillosis, a mycosis caused by Aspergillus spp.

Seabirds as anthropization indicators in two different tropical biotopes: A One Health approach to the issue of antimicrobial resistance genes pollution in oceanic islands.

Antimicrobial resistance is a quintessential One Health issue, among the most serious 21st century global threats to human health. Seabirds may act as sentinels of natural and anthropogenic changes in the marine ecosystem health, including pollution by antimicrobial resistance genes (ARGs). We used real time PCR to identify and quantify 22 plasmid-mediated ARGs in the gastrointestinal microbiome of six wild seabird species, comparing an anthropized (Fernando de Noronha Archipelago - FNA) and a pristine biotope (Rocas Atoll - ROA), Brazil.

Neoplasms and novel gammaherpesviruses in critically endangered captive European minks (Mustela lutreola).

The European mink (Mustela lutreola) is a riparian mustelid, considered one of the most endangered carnivores in the world. Alpha, beta and gammaherpesviruses described in mustelids have been occasionally associated with different pathological processes. However, there is no information about the herpesviruses species infecting European minks.
