AI Article Synopsis
- The increase in cattle egret populations in Fernando de Noronha poses risks to public health and native species due to their competition and potential transmission of diseases.
- Researchers collected cloacal swabs from 456 healthy cattle egrets, which were organized into 51 groups for testing.
- The study found Salmonella in 11.7% of the pools, identifying several serovars, suggesting that cattle egrets may act as reservoirs for this pathogen, threatening both human health and biodiversity.
Article Abstract
The growth of the population of cattle egrets (Bubulcus ibis) in the archipelago of Fernando de Noronha constitutes a threat to public health and biological diversity because of their competition with and predation on native species and the possibility of transmission of pathogens to human beings, livestock and native wildlife. The aim here was to search for, isolate and identify serovars of Salmonella in clinically healthy local cattle egrets. Cloacal swabs were obtained from 456 clinically healthy cattle egrets of both sexes and a variety of ages. The swabs were divided into 51 pools. Six of these (11.7%) presented four serovars of Salmonella enterica subspecies enterica: Salmonella serovar Typhimurium; Salmonella serovar Newport; Salmonella serovar Duisburg; and Salmonella serovar Zega. One sample was identified as S. enterica subspecies enterica O16:y:-. Results in this study suggest that cattle egrets may be reservoirs of this agent on Fernando de Noronha and represent a risk to public health and biological diversity.

Ardeids are wild birds well adapted to urban and periurban environments. However, the association of wildlife with humans and livestock increases the chances of transmission of microorganisms between wild animals, domestic animals and humans. The present study aimed to investigate the occurrence of Salmonella spp.

The residual concentration of pesticides and heavy metals (arsenic, mercury, selenium, lead, cadmium, and aluminum) was measured in the soil and the cattle egret (Bubulcus ibis) liver from two localities at Sharkia Governorate, Egypt. The pesticide residues have taken the following pattern: chlorpyrifos > metalaxyl > piperonyl butoxide > thiophanate-methyl, in the soil. The residual concentration of pesticides was greater in the soil at Kafr El-Ashraf village (agricultural site) than at El-Qanayat city (garbage site) during the summer season of 2021 compared with the winter season of 2022.

This study took advantage of a natural experiment in 2006 and 2007 when Black-crowned Night Herons were prevented from breeding at Lake Fetzara in the first year due to the presence of a feral cat. This event provided valuable insight into the spatial and temporal dynamics of nest site selection among coexisting heron species, which consisted of Cattle Egrets (), Little Egrets () and Squacco Herons ().

The present avian anatomists have shown a renewed interest in looking at whether the structure of the avian eyelid is accommodated by the kinetic achievement for each eyelid. The current work utilised both histological and anatomical methods to explore the eyelid's structural association with their kinetic, utilising the hoopoe and cattle egret as natural models. The third lid moved only without implicating other lids.

Ingestion of microplastic (MPs) in birds and its subsequent health effects has become one of the major environmental concerns. The current study is, therefore, designed to investigate the level of MPs in gastrointestinal tract of a semi-aquatic bird species, the cattle egret (Bubulcus ibis) and characterize their types, color and chemical composition. Samples (n = 5) from dead individuals were first digested then separated on the basis of density followed by vacuum filtration prior to quantification of MPs through stereomicroscopy.
