Respiratory diseases in birds generate sanitary and economic impacts and may be related to the environment and climate. Mycoplasma gallisepticum, Ornithobacterium rhinotracheale (ORT), Pasteurella multocida, Avibacterium paragallinarum, Escherichia coli, Riemerella anatipestifer, and Bordetella avium are among the most important avian respiratory pathogens. ORT is responsible for causing ornitobacteriosis, a disease characterized by clinical signs ranging from mild to severe respiratory conditions, with high mortality rates, mainly affecting turkeys and chickens. The first report of ornitobacteriosis was in 1981 in Germany. Despite its importance, few studies on ORT have been published. In addition, the presence of this pathogen has been neglected in poultry farms, mainly due to the lack of appropriate diagnostic protocols. The lack of correct isolation and diagnostic protocols along with inappropriate use of antimicrobial agents have been contributing to treatment failure. Due to its economic importance to the poultry industry, ornitobacteriosis should be monitored and included in national programs for the prevention and control of avian respiratory diseases. This review aimed to update and discuss important issues related to ORT since this pathogen has great economic and sanitary implications for the chicken production chain. [ABSTRACT FROM AUTHOR]

Rats and mice are the most used experimental models in research. Globally, animal houses are subjected to parasite outbreaks. In Brazil, the parasitological profile is used to reflect the sanitary condition of laboratory animals and must be monitored frequently. The present study developed an integrative review of scientific studies on the parasitological profile of rats and mice in animal facilities in Brazil. It identified the most prevalent parasite species reported in animal facilities from different geographic regions of the country, as well as factors contributing to the perpetuation of these parasites, and proposed measures to help prevent such infections. Based on the guiding question “which endoparasites and ectoparasites have already been identified in rat and mouse colonies in animal facilities in Brazil?” and considering inclusion and exclusion criteria, 28 studies published between 1974 and 2021 were selected in four scientific bases. These studies covered facilities in 12 Brazilian States, describing 16 genera of parasites in mice and 18 in rats. Most of the facilities in the selected studies were of the conventional type and with few sanitary barriers, and these conditions may favor the recurrence of parasites. Efforts are, therefore,necessary for institutions to have animal facilities in accordance with the legislation and practice optimal methodologies. The measures proposed in this article can contribute to change the panorama of parasites in the national animal facilities, aiming to safeguard the quality of scientific data and animal welfare.
