“…In the studies carried out by Machado et al (2018) and Teixeira (2019), there was high sensitivity to ceftiofur in the antimicrobial sensitivity test, results similar to those found in this research. However, other studies demonstrate a high rate of resistance to ceftiofur, Matias et al (2016) had 71.67% resistance to the antimicrobial mentioned above.…”

The Psittaciformes are among the most popular pets due to their intelligence, ability, and ease of maintenance in small environments. However, the absence of adequate environmental stimuli generated by confinement can predispose these animals to characteristic stress conditions, leaving them susceptible to the triggering of various diseases, among which those of bacterial origin stand out. The objective of this study was to carry out a survey of enterobacteria and evaluate the antimicrobial sensitivity profile of bacteria isolated from parrots from a pet shop in the city of Fortaleza, Ceará. Ninety-six samples were collected from four pet shops (which were classified as A, B, C and D), eight samples of local swabs from budgerigar (Melopsittacus undulatus), were collected from each establishment eight from cockatiels (Nymphicus hollandicus) and eight from lovebirds (Agapornis sp.). Isolation of enterobacteria is under the methodology used by Lopes et al. (2015) with modifications. The method used to study bacterial resistance was the Kirby-Bauer method, following the standards stipulated by the Clinical and Laboratory Standards Institute. Sixty-eight enterobacteria strains from ten different species, Proteus mirabilis, Citrobacter diversus, Pantoea agglomerans, Escherichia coli, Providencia stuartii, Hafnia alvei, Proteus vulgaris, Serratia liquefaciens, Enterobacter sakasakii and Citrobacter amalonaticus, were isolated. P. agglomerans was the bacterium with the highest frequency of isolates from pet shop parrots, making up 23.5% of the isolates; the second-most isolated strain was P. mirabilis with 17.7%. In this study, 79% of the isolated strains were resistant to at least one class of antimicrobials tested. Tetracycline proved to be the most resistant antimicrobial (44%), followed by polymyxin B (38%) and nalidixic acid (25%). Among the 68 strains, 19% did not show resistance to any of the classes of antimicrobials tested. The condition of multidrug resistance - resistance to ≥3 classes of antimicrobials - was observed in 18% of the isolated strains.

“…Concerning Escherichia coli, it is possible to observe that the results in relation to multidrug resistance are the most varied. However, it is possible to find similar rates [15], percentages lower than 5.4% or higher than 23.1% [26,84].…”

“…Environmental pollution is one of the anthropogenic actions that puts the conservation of avifauna at risk, mainly on aspects related to the dissemination of pathogens that are important for animal and public health, such as Salmonella and other enteropathogens [11,12]. Furthermore, free-ranging birds may come into contact with residues of antibiotics or resistant microorganisms when exposed to contaminants in the environment in which they live [13,14,15]. This may affect the health of birds, considering that factors such as ingestion of antibiotics and infection by pathogenic organisms may alter the microbiota of birds [16,17,18].…”

“…Anthropogenic effects on wildlife are poorly investigated, and the extent to which animal populations contribute to the spread of antibiotic resistance is still unknown. Therefore, considering that there are few studies investigating the contact that free-living birds have with multidrug-resistant enterobacteria in the Ceará State, which are generally limited to a few species, greater elucidation is needed [28,29,15,30].…”

Caatinga is a biome unique to Brazil that is degraded by anthropogenic actions, which lead to the loss of biodiversity putting many species at risk of extinction. The Ceará State is located in the Caatinga and has a rich avifauna comprised of 433 species including 13 species that are threatened with extinction, which are found in the Baturité Massif. The aim of this study was to investigate the frequency and diversity of enterobacteria in wild birds and to determine their susceptibility to antimicrobials. Cloacal swab samples were collected from 50 individuals of 28 different species, including the Ceara Gnatheter (Conopophaga cearae) and Red-necked Tanager (Tangara cyanocephala cearensis), which are classified as vulnerable (VU) by the Brazilian Ministry of the Environment. A total of 55 isolates belonging to 14 different species of Enterobacteriaceae were identified. Among these, Pantoea agglomerans and Escherichia coli were the most prevalent species with isolation rates of 36% and 26%, respectively. The highest rate of antimicrobial resistance found was to ampicillin (41.8%), followed by nalidixic Acid (36.3%) and amoxicillin associated with clavulanic acid (32.7%). The drugs with the best efficacy were tobramycin (96.4%), ciprofloxacin (92.6%) and tetracycline (90.9%). Multidrug resistance was observed in 23.5% of the analyzed strains. This research provides important information about the composition of the cloacal microbiota of wild birds in Mulungu, Brazil, as well as their health status. In addition, these results demonstrate that they harbor multidrug-resistant strains of Enterobacteriaceae.

Background: Histomoniasis is a disease caused by Histomonas meleagridis, a flagellated protozoan that can cause severe necrotizing hepatitis and typhlitis in several bird species. The disease has a cosmopolitan distribution. In experimental infection, peacocks (Pavo spp.) showed susceptibility to histomoniasis, however there are few reports on natural histomoniasis in this species. In northeastern Brazil, reports about its occurrence in avian species are scarce and nonexistent in peacocks. Therefore, this report aims to describe the epidemiological and clinicopathological aspects of a histomoniasis case in a peacock (Pavo cristatus) in the Brazilian semiarid region.Case: A 3-month-old male peacock with a history of apathy and anorexia was attended in the Veterinary Hospital of the Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró, RN, Brazil. The animal was raised extensively in a farm without basic sanitary measures, also with a history of living with animals of different species. After clinical examination, in which intense apathy and weight loss were confirmed, the bird was submitted to emergency therapeutic measures, however there was no clinical improvement and the bird died. At necropsy, intense diffuse bilateral necrotizing typhlitis and multifocal to coalescent necrotizing hepatitis were observed. Fragments of the organs were collected in 10% formaldehyde buffered with phosphate-saline buffer for histopathological analysis and cecal content were collected for microbiological analysis. Histopathology of the cecum revealed transmural necrotizing typhlitis associated with myriads of trophozoites morphologically compatible with Histomonas meleagridis. The same microorganisms observed in association with necrotizing hepatitis lesions, which allowed the diagnosis of histomoniasis. Also, the bacterium Pantoea agglomerans was isolated from the cecal content.Discussion: The macroscopic and microscopic findings allowed the diagnosis and the first recording of histomoniasis in peacock in the semi-arid region of Rio Grande do Norte. The bird was raised in an extensive breeding and without sanitary management, such as the use of anthelmintics, which may favor infection by the nematode Heterakis gallinarum, that’ transmits the protozoan Histomonas meleagridis. The contamination, which begins by the orofecal route, happens through the ingestion of eggs of the nematode contaminated with H. meleagridis that pass through the gastrointestinal tract, reaching the ceca and causing intense lesions in the organ, such as the bilateral transmural typhlitis that we observed in this case. From ceca, the protozoan has access to the bloodstream and reaches the liver, where it causes necrotic hepatitis, also present in the peacock. Both cecal and hepatic lesions were associated with myriads of microorganisms morphologically compatible with H. meleagridis, which allowed the diagnosis of the disease. The challenge in diagnosing this disease occurs mainly due to nonspecific clinical signs, such as apathy and weight loss, the only signs reported by the breeder and observed in this peacock. Confirmation of the occurrence of histomoniasis in any region is important to establish the disease among the differential diagnoses for the species, as in this case. Since this is the first report of peacock histomoniasis in the semi-arid region of Rio Grande do Norte, it is evident the need to consider the disease among possible diagnoses in cases of nonspecific symptoms and it also demonstrates the need to implement control and prophylaxis measures in peacock breeding aiming to avoid losses of birds and economic losses to the breeders and to promote quality of life to the animals.
