Sarna knemidocóptica (Knemidokoptes spp. ) Em periquitos australianos (Melopsittacus undulatus): relato de caso / Knemidocoptic mange (Knemidokoptes spp. ) In australian parakeets (Melopsittacus undulatus): case report

Sarna knemidocóptica apresenta relevante importância na clínica e criação de aves. São caracterizadas como ectoparasitos penetrantes, escavadores de túneis dérmicos de hospedeiros susceptíveis, causando-lhes lesões cutâneas graves e parasitando extensa gama de espécies, principalmente aquelas criadas em cativeiro. Periquitos australianos (Melopsittacus undulatus) são uma das aves psitacídeas mais comumente mantidas como animais de companhia e, destacando-se entre outras ectoparasitoses, como: ácaros das penas, dos ninhos e larvas de moscas, está o gênero Knemidokoptes spp., responsável pela sarna dos periquitos. Neste relato, foram observados sete M. undulatus da variedade inglesa, adultos sendo quatro fêmeas e 3 machos obtidos na cidade de Porto Ferreira, São Paulo. As aves apresentavam-se irritadas, coçando-se, com mutilações variadas. Pode-se observar níveis distintos de patologia nos exemplares e lesões foram observadas em toda a extensão da pele: do crânio, cera (nariz), bico, derme das asas, cauda e membros inferiores (patas), levado a ausência de penas, formação de placas elevadas de superfície irregular, porosa de coloração brancacenta e aspecto crostoso poroso. Os bordos das lesões apresentavam-se avermelhadas, onde as aves bicavam para coçar até se mutilarem. Foi coletado material córneo das áreas lesionadas e em 100%, observou-se ao microscópio óptico (40x), instares da sarna que, por características morfológicas e parasitárias, sugere-se ser a espécie K. pilae. Cinco dos sete animais: quatro fêmeas e um macho, com maior nível de lesões vieram a óbito mesmo iniciado o tratamento e duas aves: macho, menos infestadas foram curadas, porém perdurando sequelas dérmicas e hábito de coçar os membros. Este é o primeiro relato, comprovado por identificação microscópica do ácaro parasitando periquitos padrão inglês atendidos em Descalvado, SP.

Knemidocoptic mange is of relevant importance in clinical and poultry breeding. They are characterized as penetrating ectoparasites, burrowing into dermal tunnels of susceptible hosts, causing severe skin lesions and parasitizing a wide range of species, especially those bred in captivity. Australian parakeets (Melopsittacus undulatus) are one of the parrot birds most commonly kept as companion animals and, standing out among other ectoparasitosis such as: feather mites, nest mites and fly larvae, is the genus Knemidokoptes spp., responsible for mange of birds. parakeets. In this report, seven M. undulatus of the English variety were observed, adults, four females and 3 males, obtained in the city of Porto Ferreira, São Paulo. The birds were irritated, scratching themselves, with various mutilations. Different levels of pathology can be observed in the specimens and lesions were observed along the entire length of the skin: skull, wax (nose), beak, wing dermis, tail and lower limbs (legs), leading to the absence of feathers, formation of raised plaques with irregular surface, porous, whitish color and scaly porous appearance. The edges of the lesions were reddened, where the birds pecked to scratch until they mutilated themselves. Corneal material was collected from the injured areas and 100% of the scab instars were observed under an optical microscope (40x), which, due to morphological and parasitic characteristics, is suggested to be the species K. pilae. Five of the seven animals: four females and one male, with a higher level of lesions, died even after the treatment was started, and two birds: male, less infested were cured, but with dermal sequelae and the habit of scratching the limbs. This is the first report, confirmed by microscopic identification of the mite parasitizing English standard parakeets in Descalvado, SP.

Zoonotic bacteria research and analysis of antimicrobial resistance levels in parrot isolates from pet shops in the city of Fortaleza, Brazil

ABSTRACT: 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.

RESUMO: Os psittaciformes estão entre os animais de estimação mais populares devido sua inteligência, habilidade, além da facilidade de manutenção da espécie em pequenos ambientes. Contudo, a ausência de estímulos ambientais adequados gerados pelo confinamento, podem predispor esses animais a quadros característicos de estresse, deixando-os susceptíveis ao desencadeamento de várias doenças dentre elas se destacam as de origem bacteriana. O objetivo desse trabalho foi realizar uma pesquisa de enterobactérias e avaliar o perfil de sensibilidade antimicrobiana de bactérias isoladas de psitacídeos de pet shop da cidade de Fortaleza, Ceará. Foram coletadas 96 amostras de quatro pet shops (os quais foram classificados em A, B, C e D), sendo coletados de cada estabelecimento oito amostras de suabes clocais oriundos de periquitos australianos (Melopsittacus undulatus), oito de calopsitas (Nymphicus hollandicus) e oito de agapornis (Agapornis sp.). O isolamento de enterobactérias está de acordo com a metodologia utilizada por Lopes et al. (2015) com modificações. O método utilizado para o estudo de resistência bacteriana foi o de Kirby-Bauer, seguindo os padrões estipulados pela Clinical and Laboratory Standards Institute. Foi isolado um total de 68 cepas de enterobactérias, de dez espécies diferentes, Proteus mirabilis, Citrobacter diversus, Pantoea agglomerans, Escherichia coli, Providencia stuartii, Hafnia alvei, Proteus vulgaris, Serratia liquefaciens, Enterobacter sakasakii e Citrobacter amalonaticus. Pantoea agglomerans foi a bactéria com maior percentagem de frequência dos isolados de psitacídeos de pet shop, perfazendo um total de 23,5% dos isolados, a segunda cepa mais isolada foi Proteus mirabilis com 17,7%. Neste estudo 79% das cepas isoladas foram resistentes a pelo menos uma classe de antimicrobianos testados, tetraciclina demonstrou ser o antimicrobiano com maior resistência (44%), seguido da polimixina B (38%) e do ácido nalidíxico (25%). Dentre as 68 cepas isoladas, 19% não apresentaram resistência a qualquer uma das classes de antimicrobianos testadas. A condição de multirresistência, ou seja, resistência a 3 classes de antimicrobianos foi observado em 18% das cepas isoladas.

Testicular development induced by GnRH-IS in budgerigar (Melopsittacus undulatus)

Nowadays, the third part of parrots in the world is endangered or vulnerable; an alternative for their preservation is assisted reproduction in captivity through hormonal manipulation. In birds, GnRH is the main hormone which controls reproductive physiology, it is known there are three types: GnRH-I, GnRH-II and GnRH-III, involved in the release or inhibition of luteinizing hormone and follicle stimulant hormone to control gonadal and gametic development. The objective of this study was, to evaluate the effect of administrating synthetic GnRH-I in the testicular development of Melopsittacus undulatus. Twenty-eight adult budgerigars were randomly divided in two groups: control (n=14) and treated (n=14) with a unique dose of synthetic GnRH-I. Testicular development was assessed through ultrasonography and density was evaluated with pixels. Germinal diameter and thickness of germinal epithelium were determined with histology; there were identified and countified different cellular strains in seminiferous tubules therefore spermatobioscopy. Results. Ecographic density was: control group: 76 ± 7 pixels, treated group 41 ± 3 pixels. Thickness of germinal epitellium, 51.5 ± 2.9µm and 73.1 ± 3.1µm, for control group and treated group respectively. Sperm concentration in the treated group was 300% superior than in control group. It is concluded that the administration of synthetic GnRH-I, is a viable alternative to be used as part of the assisted

First report of psittacine beak and feather disease in importedbudgerigar (Melopsittacus undulatus) chicks in Mexico

This case reports an outbreak of psittacine beak and feather disease in imported budgerigars (Melopsittacusundulatus) in a breeding site in Mexico. Feather abnormalities occurred in 3-month-old budgerigars and the percentage of affected birds was 40 of 100 birds (40%). The disease begins with varying degrees of bare skin on the back, the ventral region of the body, and the thoracic and pelvic regions without clinical signs or mortality offspring. Thirty-tree budgerigars were referred to the laboratory for diagnostics work-up. The hemogram showed different stages of inflammation in all studied birds, where 66% had relative erythrocytosis, leukocytosis due to heterophilia and monocytosis associated with chronic inflammation. The biochemical analysis showed mainly hypoproteinemia and hypouricemia in 5/8 and 4/9 birds, respectively. The absence of feathers with some tiny calamus of the pectoral region was the most significant feature and no other significant pathologic changes were observed. Histopathologic findings were apoptosis and a moderate amount of spherical intracytoplasmic basophilic inclusion bodies in clusters in some epithelial cells of feather follicles (12/14 sections examined) and bursa of Fabricius (8/10 sections examined). End-point PCR of bursa of Fabricius, genome sequencing and phylogenetic analysis, confirmed circovirus identification of the psittacine beak and feather disease virus species and belonging to the group 2 previously found in budgerigars. This is the first description of the psittacine beak and feather disease in budgerigars in Mexico showing the need of monitoring health status of companion and free-ranging endemic and endangered psittacine birds in Mexico in order to collaborate with the trade regulation of these bird species.(AU)

A retrospective study of neoplasms in ornamental and pet birds diagnosed at the Hospital de Aves of the Universidad Nacional Autónoma de México (2007-2014)

A retrospective study including a total of 44 ornamental and pet birds with neoplasms diagnosed at the Hospital de Aves, Facultad de Medicina Veterinaria y Zootecnia, Universidad Nacional Autónoma de México from January 2007 to April 2014 was conducted. Most of affected birds were Psittaciformes (n=26, 59%) including budgerigars (Melopsittacus undulatus) (n=12/26, 46.15%) and amazon parrots (Amazona spp.) (n=7/26, 26.92%), and followed by Passeriformes and Anseriformes (n=7/44, 15.90%, each) and Galliformes (n=4/44, 9.09%). The youngest studied bird was a 6.5-week-old lovebird (Agapornis sp.) with a papilloma, and the oldest bird was a 37-year-old yellow-naped parrot (Amazona auropalliata) with a hemangiosarcoma. Most of the affected birds were adults (n=23, 52.27%). The gender was determined for 17 birds (38.63%), of which eight (47.05%) were females and nine (52.94%) males. There were 45 reported neoplasms,as one salmon-crested cockatoo (Cacatua moluccensis) had two neoplasms. The two most frequent neoplasms were fibrosarcomas (n=9/45, 20%) and hemangiosarcomas (n=5/45, 11.11%). The largest number of neoplasms was found in the integumentary system (n=18/45, 40%), followed by the reproductive system (n=10/45, 22.22%). Of the 16 types of neoplasms, seven (43.75%) were malignant, six (37.5%) were benign, and three (18.75%) were potentially malignant. This study showed similarities with retrospective previously reported studies and contributes to the knowledge of the neoplastic diseases that occur in ornamental and pet birds in Mexico.(AU)

Efeitos sedativos da administração intranasal ou intramuscular de midazolam associado ou não ao butorfanol em periquito autraliano (Melopsitacus undulatus) / Sedative effects of intranasal or intramuscular administration of midazolamwith or without butorphanol in budgerigards (Melopsitacus undulatus)

Frequentemente o Médico Veterinário é requisitado para realização de diversos procedimentos em aves, os quais geralmente necessitam de sedação ou anestesia geral. Este trabalho teve como objetivo comparar os efeitos sedativos do midazolam (5 mg.kg-1) associado ou não ao butorfanol (1 mg.kg-1) pelas vias de administração intranasal ou intramuscular. Sete periquitos australianos foram submetidos a quatro tratamentos em delineamento do tipo crossover com 15 dias de intervalo. Foram avaliados os períodos de latência, tempos de decúbito dorsal, tempos de sedação, tempos de recuperação, grau de sedação e qualidade de recuperação. Os resultados paramétricos foram avaliados por análise de variância de uma via seguida por teste de Student-Newman-Keuls e os dados não paramétricos foram submetidos ao teste Kruskal-Wallis ambos com 5% de significância. A técnica intranasal demonstrou melhores graus de sedação, no entanto, concluiu-se que ambos os protocolos e as vias de administração avaliados são seguras e viáveis para sedação em periquito australiano.(AU)

Often veterinarians have attended various species of birds to perform clinical procedures, which require sedation or generalanesthesia. The aim of this study was compare the intranasal or intramuscular sedative effects of midazolam (5 mg.kg-1) withor without butorphanol (1 mg.kg-1). Seven budgerigards (Melopsitacus undulates) were submitted in a crossover design to fourtreatments. The procedures were performed with 15 days washout. Were evaluated the on set time, dorsal recumbency timeduration, total sedation period, total recovery time, sedation degree and recovery quality. The parametric results were analisedby one way ANOVA following Student-Newman-Keuls test and non-parametric datas were submitted to Kruskal-Wallis test, bothwith 5% significance. The intranasal technical demonstrates best degrees of sedation, however, this study concluded that bothprotocols and the administration routes are safe and viable for sedation in budgerigards.(AU)

EFEITOS ANESTÉSICOS DA ADMINISTRAÇÃO INTRANASAL OU INTRAMUSCULAR DA ASSOCIAÇÃO DE MIDAZOLAM E CETAMINA RACÊMICA OU S+ EM PERIQUITO AUSTRALIANO (Melopsittacus undulatus)

Abstract Intranasal anesthesia in birds is considered a safe, simple and efficient technique. The aim of this study was compare the anesthetic effects of midazolam (5 mg.kg-1) with racemic (R) or S+ (S) ketamine (15 mg.kg-1), administered intranasally (IN) or intramuscularly (IM) in budgerigars (Melopsittacus undulatus). Eight budgerigars were used in a crossover design with four treatments: INR, INS, IMR and IMS. Onset time, dorsal recumbency time duration, total anesthesia time, total recovery time, sedation degree and recovery quality were evaluated. Significant differences were observed in onset time between INS (40.25±10.55 sec) and IMR (74.32±21.77 sec); between administration vials for dorsal recumbency time, INS (23.93±7.51 min) and INR (28.68±16.13 min), which were different from IMS (60.08 ± 27.37 min) and IMR (74.3±21 min). In total anesthesia time, INS (45.48±17.94 min) and INR (39.24±15.62 min) were different from IMS (75.84±20.20 min) and IMR (20.73±79.4 min). The total recovery time was significantly higher in INS (21.55±18.43 min) compared to IMR (5.1±3.56 min). The results of this study indicated that both administration vials can be used for short time non-invasive procedures and the intranasal vial is preferable for fast procedures.

Resumo A anestesia intranasal em aves é considerada uma técnica anestésica segura, simples e eficiente. O objetivo deste estudo foi comparar os efeitos anestésicos da associação de midazolam (5 mg.kg-1) e cetamina (15 mg.kg-1) nas formulações racêmica (R) ou S+ (S) administrados pela via intranasal (IN) ou intramuscular (IM) em periquitos australianos (Melopsittacus undulatus). Foram utilizados oito periquitos em delineamento do tipo crossover, em quatro tratamentos: INR, INS, IMR e IMS. Foram avaliados os tempos de latência, decúbito dorsal, anestesia e recuperação, grau de sedação e qualidade de recuperação. Foi observada diferença significativa no tempo de latência entre INS (40,25±10,55 seg) e IMR (74,32±21,77 seg); entre as vias de administração para o tempo de decúbito dorsal, INS (23,93±7,51 min) e INR (28,68±16,13 min), diferente de IMS (60,08±27,37 min) e IMR (74,3±21,77 min) e para tempo de anestesia, INS (45,48±17,94 min) e INR (39,24±15,62 min), diferentes de IMS (75,84±20,20 min) e IMR (79,4±20,73 min). O tempo de recuperação foi significativamente maior em INS (21,55±18,43 min) comparado a IMR (5,1±3,56 min). Pode-se concluir que as duas vias de administração avaliadas podem ser utilizadas em procedimentos de curta duração e não invasivos e a via intranasal é preferível para procedimentos rápidos.

Ingluvoliths in budgerigar: case report / Ingluvolitos em periquito australiano: relato de caso

The gastrointestinal tract of birds presents unique anatomy and physiology. The crop or chat, is a distension of the esophagus with function of storing food. Injuries and masses in these locations can occur for various reasons causing feeding difficulties and thinning of the bird. Food or foreign body impacted inside tract gatrintestinal can form the bezoars. Thus, the objective was reporting the occurrence of masses in crop in a budgerigar attended at the Veterinary Hospital of the Universidade Federal de Uberlândia, and diagnosed as phytobezoar or ingluvoliths after necropsy examination and evaluation of the mass found(AU)

O trato gastrointestinal das aves apresenta anatomia e fisiologia únicas. O inglúvio, ou papo, é uma distensão do esôfago com função de armazenar alimentos. Lesões e massas nesses locais podem ocorrer por diversos motivos, provocando dificuldades alimentares e emagrecimento da ave. O alimento ou material estranho impactado no interior de trato gastrintestinal pode formar os bezoares. Assim, objetivou-se descrever a ocorrência de massas em inglúvio de um periquito australiano atendido no Hospital Veterinário da Universidade Federal de Uberlândia, e identificadas como fitobezoar ou ingluvolitos após exame necroscópico e avaliação das massas encontradas(AU)

Avaliação de dois métodos de estocagem de amostras teciduais para diagnóstico molecular de Sarcocystis spp

No Brasil existem três espécies de gambás, Didelphis aurita, Didelphis albiventris e Didelphis marsupialis. Entre os diversos agentes patológicos que estes hospedeiros albergam, estão os protozoários do gênero Sarcocystis de grande interesse na medicina veterinária por causar a Mieloencefalite Protozoária Equina (EPM). Com a evolução dos métodos de diagnóstico a biologia molecular possibilitou a identificação de espécies em hospedeiros diferentes. Com isso o presente trabalho tem por objetivo avaliar dois métodos de conservação tecidual com a finalidade de melhorar o diagnóstico molecular. Para tanto, foram utilizados cinco gambás D. aurita para a obtenção dos esporocistos contidos na lâmina própria do intestino delgado. Estes foram extraídos da mucosa após digestão da mesma com hipoclorito de sódio 10%. Após a contagem e morfometria dos esporocistos, cada amostra foi padronizada em inóculos contendo 60 e 120 esporocistos em 1 mL, que foram inoculados em periquitos australianos (Melopsittacus undulatus). Dois periquitos foram inoculados com solução de soro fisiológico, perfazendo um total de 12 periquitos. De todos os periquitos que morreram ou foram eutanasiados no período de quatro meses, foram coletadas amostras de tecidos e conservadas a temperatura de -20 ºC com e sem a imersão em álcool absoluto. Foi realizada a biologia molecular dos esporocistos com o primer ITS 18S 9L/1H. Utilizando este mesmo primer foi realizado o diagnóstico molecular dos seguintes tecidos: coração, língua, coxa, peito, fígado, pulmão e cérebro, com o intuito de comparar a eficiência dos métodos de conservação. Como resultado dos valores morfométricos em micrômetros dos esporocistos obtivemos o comprimento médio de 11,2 ± 0,9 (7-15,6) e largura média de 7,7 ± 0,6 (3,8-10,9). Todas as amostras de raspado de mucosa contendo os esporocistos foram positivas para a PCR utilizando o primer ITS. O método de conservação a -20°C sem e com imersão em álcool absoluto apresentaram eficiência na preservação do DNA dos tecidos, embora não foram encontradas diferenças estatísticas significativas entre os dois métodos avaliados. Nas infecções agudas foram observadas lesões histopatológicas em região hepática e pulmonar, com formação de merontes nos pulmões. Nas infecções crônicas foram encontrados 20 cistos maduros e imaturos nos tecidos do peito, coxa e da língua que mensurados tiveram valores em micrômetros de 25,4 ± 7,1 (12,7-34,8) de largura e 45,9 ± 24,6 (16,8-113,0) de comprimento. Com os resultados obtidos podemos inferir que os gambás D. aurita estão parasitados com espécies de Sarcosystis spp. que tem aves como hospedeiro intermediário.

In Brazil there are three species of possums, Didelphis aurita, Didelphis albiventris and Didelphis marsupialis. Among the various pathological agents that these hosts harbor, protozoa of the genus Sarcocystis is object of great interest in veterinary medicine for causing Equine Protozoan Myeloencephalitis (EPM). With the evolution of diagnostic methods, molecular biology has enabled to identify species in different hosts. Thus, the present work aims to evaluate two methods of tissue conservation in order to improve the molecular diagnosis. For this purpose, five D. aurita possums were used to obtain the sporocysts contained in the small intestine lamina propria. These were extracted from the mucosa after digestion with 10% sodium hypochlorite. After sporocyst counting and morphometry, each sample was standardized on inocula containing 60 and 120 sporocysts in 1 mL, which were inoculated into budgerigars (Melopsittacus undulatus). Two parakeets were inoculated with saline solution, making a total of 12 parakeets. From all the parakeets that died or were euthanized in the period of four months, tissue samples were collected and kept at -20 ºC with and without immersion in absolute alcohol. Molecular biology of the sporocysts was performed with the ITS 18S 9L / 1H primer. Using this same primer, the molecular diagnosis of the following tissues was performed: heart, language, thigh, chest, liver, lung and brain, in order to compare the efficiency of conservation methods. As a result of the morphometric values in micrometers of the sporocysts, we obtained an average length of 11.2 ± 0.9 (7-15.6) and an average width of 7.7 ± 0.6 (3.8-10.9). All mucosa scrape samples containing sporocysts were positive for PCR using the ITS primer. The method of conservation at -20 ° C without and with immersion in absolute alcohol showed efficiency in the preservation of DNA tissue, although no statistically significant differences were found between the two methods evaluated. In acute infections, histopathological lesions were observed in the hepatic and pulmonary regions, with formation of merons in the lungs. In chronic infections, 20 mature and immature cysts were found in the chest thigh and tongue tissues, which were measured with micrometers values of 25.4 ± 7.1 (12.7-34.8) in width and 45.9 ± 24.6 (16.8-113.0) in length. With the results obtained, its possible to infer that D. aurita possums are parasitized with Sarcosystis spp. species that have birds as an intermediate host.

Os psitacídeos estão entre as aves mais procuradas como animais de companhia, por causa da sua docilidade, beleza e inteligência, alguns indivíduos possuem a capacidade de imitar a voz humana, sendo de fácil adaptação em ambiente doméstico. Várias doenças são transmitidas de aves em cativeiro para os seres humanos através do contato direto ou indireto com aves doentes ou portadoras assintomáticas. Dentre estas doenças, destacam-se as de origem bacteriana. Esse trabalho tem como objetivo, investigar enterobactérias oriundas de psitacídeos de pet shop da cidade de Fortaleza, Ceará e avaliar o perfil de sensibilidade antimicrobiana das cepas bacterianas isoladas. Este projeto foi aprovado pelo comitê de ética, com o seguinte número de protocolo, CEUA: 2893348/2017. Foram coletadas 96 amostras de 04 pet shops (os quais foram classificados em A, B, C e D) situados na cidade de Fortaleza-CE, sendo coletado de cada estabelecimento 08 amostras de suabes clocais oriundos de periquitos australianos (Melopsittacus undulatus), 08 de calopsitas (Nymphicus hollandicus) e 08 de agapornis (Agapornis sp.). Das 96 amostras coletadas, foi isolado um total de 68 cepas de enterobactérias, de 10 espécies diferentes, Proteus mirabilis, Citrobacter diversus, Pantoea agglomerans, Escherichia coli, Providencia stuartti, Hafnia alvei, Proteus vulgares, Serratia liquefaciens, Enterobacter sakasakii e Citrobacter amalonaticus. Pantoea agglomerans foi à bactéria com maior percentagem de frequência dos isolados de psitacídeos de pet shop, perfazendo um total de 23,5% dos isolados, a segunda cepa mais isolada foi a Proteus mirabilis com 17,7%. A tetraciclina demonstrou ser o antibiótico com maior resistência, com sobrevida de 44%, seguida da polimixina b (38%) e do ácido nalidíxico (25%). Dentre as 68 cepas isoladas neste estudo, treze (19%) não apresentaram resistência a qualquer uma das classes de antibióticos testadas. Treze cepas (16%) apresentaram resistência a 3 classes de antibióticos, ou seja, condição de multiresistência. Dessa forma, observou-se que psitacídeos de pet shop, podem albergar enterobactérias resistentes e/ou multiresistente aos antimicrobianos testados.

Parrots are among the most sought after birds as companion animals, because of their docility, beauty and intelligence, some have an ability to imitate the human voice, being easy to adapt in the domestic environment. Various diseases are transmitted from birds in captivity to humans through direct or indirect contact with sick birds or asymptomatic carriers. Among these diseases, those of bacterial origin stand out. This work aims to investigate enterobacteria from pet shop parrots in the city of Fortaleza, Ceará and to evaluate the antimicrobial sensitivity profile of bacterial strains. This project was approved by the ethics committee, with the following protocol number, CEUA: 2893348/2017. 96 administrators were collected from 04 pet shops (which were classified as A, B, C and D) located in the city of Fortaleza-CE, being collected from each establishment 08 the local swabs from Australian parakeets (Melopsittacus undulatus), 08 of cockatiels (Nymphicus hollandicus) and 08 of lovebirds (Agapornis sp.). Of the 96 collected, it was isolated from a total of 68 strains of enterobacteria, from 10 different species, Proteus mirabilis, Citrobacter diversus, Pantoea agglomerans, Escherichia coli, Providencia stuartti, Hafnia alvei, Proteus vulgares, Serratia liquefaciens, Enterobacter sakasakii and Citrobacter amalonaticus. Pantoea aglomerans was the bacterium with the highest frequency of pet shop parrots, making up a total of 23.5% of those required, the second most isolated strain was Proteus mirabilis with 17.7%. Tetracycline is considered to be the antibiotic with the highest resistance, with a 44% survival rate, followed by polymyxin b (38%) and nalidixic acid (25%). Among the 68 strains consolidated in this study, thirteen (19%) did not resist any of the tested antibiotic classes.
