Histology and immunofluorescent study of the pancreas in lovebird (Agapornis personatus).

BACKGROUND: Lovebird (Agapornis personatus) is a monotypic species of bird of the lovebird genus in the parrot family Psittaculidae and order Psittaciformes. OBJECTIVES: The present study was designed to investigate the histology and immunohistochemistry of the pancreas in the lovebird. METHODS: Totally, three adult birds were used. The pancreas was assessed using histological and immunofluorescent staining to detect insulin, glucagon, somatostatin, pancreatic polypeptide (PP) and neuropeptide Y (NY). RESULTS: The exocrine pancreas was composed of pyramidal acinar cells with zymogen granules at the apical cytoplasm. The endocrine pancreas was identified as large alpha, small beta and mixed islets of Langerhans. No intercalated duct was observed. Alpha cells with a density of 28.55% were the most numerous cell type, which were populated throughout the large islets, especially at the periphery. The beta cells with a density of 15.78% were accumulated mostly at the periphery of islets. The delta cells exhibited 17.81% intensity. Despite their lower density, the distribution of delta cells was like that of A cells throughout the islets. PP and NY cells were distinguished with densities of 14.69% and 20.63%, respectively. CONCLUSIONS: Although the arrangement of acinar cells, ductal systems and endocrine islets reflects patterns observed in various avian species, the absence of intercalated duct, the presence of three types of Langerhans islets as alpha, beta and mixed islets and the high expression of NY in the islets were some unique features observed in the current study. These findings contribute to the broader understanding of avian pancreas histology.

COMPARISON OF THREE MIDAZOLAM-BASED SEDATION PROTOCOLS IN BUDGERIGARS (MELOPSITTACUS UNDULATUS) AND BLACK-CHEEKED LOVEBIRDS (AGAPORNIS NIGRIGENIS).

This randomized, crossover study evaluated three sedation protocols administered subcutaneously in nine budgerigars (Melopsittacus undulatus) and nine black-cheeked lovebirds (Agapornis nigrigenis). All protocols included midazolam (5 mg/kg), combined with butorphanol (5 mg/kg) (BM), medetomidine (20 lg/kg) (MM), or alfaxalone (13 mg/kg) (AM). Mortalities from suspected cardiorespiratory arrest were observed when AM was used in lovebirds, even after reduction of alfaxalone dosage to 3 mg/kg, and therefore this protocol was excluded from further use in this species. Induction and recovery times were recorded and their quality assessed. Sedation depth and heart and respiratory rates were measured every 5 min and radiographic positioning was attempted at 10 and 20 min. At 30 min, midazolam and medetomidine were reversed with flumazenil (0.05 mg/kg, SC), and atipamezole (0.2 mg/kg, SC), respectively. MM consistently provided deep sedation in both species, with successful radiographic positioning at every attempt. As expected, heart rate was often lower with MM than with other protocols, but no associated complications were noted. In budgerigars, BM had the lowest radiographic positioning success rate (10 min: 5/9, 20 min: 3/9), whereas in lovebirds it provided significantly deeper sedation (P < 0.001), allowing radiographic positioning in all subjects. In both species, BM provided the shortest recovery times. AM resulted in reliable radiographic positioning of all budgerigars at 10 min, but not at 20 min (5/ 9), and provided consistently poor recoveries. This study highlights how differently two psittacine species of similar size may react to the same sedation protocols. AM sedation cannot be fully reversed and produced significant undesirable effects, several of which have been previously reported with alfaxalone administration to avian species. The authors therefore caution against using alfaxalone-midazolam combinations in budgerigars and black-cheeked lovebirds. Both BM and MM provided reliable sedation in these species, and appear to be suitable alternatives to AM.

Diagnosis and Treatment of Gordonia Species Infection in a Peach-Faced Lovebird (Agapornis roseicollis).

Respiratory distress is a common presentation for avian species. A 9-week-old peach-faced lovebird (Agapornis roseicollis) was presented with a 2-week history of progressive dyspnea. Computed tomographic (CT) images were suggestive of splenomegaly and bilateral granulomatous pulmonary disease. Polymerase chain reaction testing of samples from the choana, cloaca, and distal tracheal/syringeal area were positive for Mycobacterium species hsp65. A comparison search of the 400 base pair sequence in the NCBI/BLAST/blastn database revealed a best match of 93% similarity to Gordonia species and 91% similarity to Gordonia bronchialis. Gordonia is a genus in the phylum Actinomycetota, the same lineage that includes Mycobacterium species. Gordonia species can be mistaken for Mycobacterium species unless more definitive diagnostic testing is pursued. Infection caused by Gordonia species is rare in humans. Reports commonly cite infection of immunocompromised patients, and to our knowledge, no reports of treatment have been published in the veterinary literature. After the test results were obtained, the patient was treated with azithromycin and pradofloxacin for 3 months. The lovebird was presented for reexamination when the antibiotic treatment was complete. When reexamined, and a second series of CT images evaluated, it was determined that the treatment achieved clinical resolution of signs and lesions.

Museomics and phylogenomics of lovebirds (Psittaciformes, Psittaculidae, Agapornis) using low-coverage whole-genome sequencing.

Natural history collections contain specimens that provide important insights into studies of ecology and evolution. With the advancement of high-throughput sequencing, historical DNA (hDNA) from museum specimens has become a valuable source of genomic data to study the evolutionary history of organisms. Low-coverage whole genome sequencing (WGS) has been increasingly applied to museum specimens for analyzing organelle genomes, but is still uncommon for genotyping the nuclear DNA fraction. In this study, we applied low-coverage WGS to phylogenomic analyses of parrots in the genus Agapornis by including both modern samples and historical specimens of âˆ¼100-year-old. Agapornis are small-sized African and Malagasy parrots with diverse characters. Earlier phylogenetic studies failed to resolve the positions of some key lineages, prohibiting a robust interpretation of the biogeography and evolution of these African parrots. Here, we demonstrated the use of low-coverage WGS for generating both mitochondrial and nuclear genomic data, and evaluated data quality differences between modern and historical samples. Our resolved Agapornis phylogeny indicates the ancestor of Agapornis likely colonized Madagascar from Australasia by trans-oceanic dispersal events before dispersing to the African continent. Genome-wide SNPs also allowed us to identify the parental origins of hybrid Agapornis individuals. This study demonstrates the potential of applying low-coverage WGS to phylogenomics and population genomics analyses and illustrates how including historical museum specimens can address outstanding questions regarding the evolutionary history of contemporary lineages.

Undifferentiated Wing Sarcoma in a Peach-Faced Lovebird (Agapornis roseicollis).

A 10-year-old peach-faced lovebird (Agapornis roseicollis) was evaluated for an ulcerated and painful mass at the location of a fracture 2 years previously. Whole body radiographs showed a humeral fracture with a presumptive neoplastic proliferation in the distal diaphysis. Right wing amputation was elected but the animal died during recovery from surgery. Histopathological examination of the amputated wing revealed an infiltrative sarcomatous neoplastic proliferation. Immunohistochemistry (IHC) was carried out to characterize the tumour using antibodies against vimentin, desmin, smooth muscle actin (SMA), S-100, ionized calcium-binding adapter molecule-1 (IBA-1), CD18, cytokeratin and epithelial membrane antigen (EMA). The mesenchymal component of the mass was immunolabelled for vimentin and SMA and sparse epithelial cells were immunopositive for cytokeratin. Very few scattered cells were immunopositive for CD18 and IBA-1. The final diagnosis was consistent with an undifferentiated sarcoma with intralesional hyperplastic epithelium. According to the location, the history of a previous fracture and the histological pattern and IHC profile, the tumour was classified as an undifferentiated sarcoma with entrapped air sac epithelium.

The influence of substrate size upon pulling and gripping forces in parrots (Psittaciformes: Agapornis roseicollis).

The ability to securely grasp substrates of variable diameter is critical to arboreal animals. Arboreal specialists have emerged across several vertebrate lineages - including mammals, lizards and amphibians - and several attempts have been made to quantify their grasping performance, by measuring either gripping (i.e. forces generated about an object or substrate enclosed within the digits) or pulling (i.e. the ability to resist being removed from a substrate) forces. In this study, we present data on both pulling and gripping performance across a range of substrate diameters (0.5-17.5 mm) within a model parrot species (Agapornis roseicollis). Parrots represent an ancient arboreal lineage, allowing us to compare their abilities with those of arboreal specialists within other tetrapod groups. Data were collected using 3D-printed perches of variable diameter, and forces were registered using either an AMTI low-load force plate (grip force) or a Harvard Apparatus portable strength tester (pull force). Gripping forces peaked at a 5 mm diameter perch, while pulling forces were greatest at a 2.5 mm diameter. All forces strongly diminished above 10 mm size, suggesting grip force is optimized when utilizing small perches, a finding which corresponds to observational studies of preferential perching habits among free-ranging parrots. Relative grasping performance (adjusted for body size) in parrots is roughly equivalent to that of other arboreal specialists from other tetrapod lineages, but low when compared with that of raptorial birds that utilize their feet during aerial prey capture. Further taxonomic sampling is encouraged to contextualize how grasping performance varies in an adaptive evolutionary context.

Liposarcoma of Probable Medullary Bone Origin in a Lovebird (Agapornis roseicollis).

A 15-year-old female peach-faced lovebird (Agapornis roseicollis) was presented to the hospital for a possible left wing injury and an inability to fly after falling in its cage. On physical examination the left elbow was swollen and painful. Radiographic images revealed left wing soft tissue swelling surrounding the elbow and lysis of the distal humerus with extensive cortical thinning. Subsequent high-definition volumetric-imaging 3-dimensional computed tomography (HDVI 3D CT) revealed a pathological fracture, cortical lysis, periosteal reaction, and abnormal intraosseous soft tissue of the left humerus with associated soft tissue swelling, suggestive of neoplasia. No evidence of metastatic disease was identified. Surgical amputation of the left wing was elected. A liposarcoma and pathologic fracture of the humerus were diagnosed histologically and by oil red O staining for lipids in the neoplastic cells. The morphologic features of the tumor suggested that it developed within the adipocyte component of the medullary bone. The incision at the amputation site healed without complication. A follow-up HDVI 3D CT performed 4 months postsurgery showed no evidence of metastatic disease. To the authors' knowledge, this is the first report of a primary liposarcoma of medullary bone origin in an avian species.

Patterns of single limb forces during terrestrial and arboreal locomotion in rosy-faced lovebirds (Psittaciformes: Agapornis roseicollis).

The biomechanical demands of arboreal locomotion are generally thought to necessitate specialized kinetic and kinematic gait characteristics. While such data have been widely collected across arboreal quadrupeds, no study has yet explored how arboreal substrates influence the locomotor behavior of birds. Parrots - an ancient arboreal lineage that exhibit numerous anatomical specializations towards life in the trees - represent an ideal model group within which to examine this relationship. Here, we quantifiy limb loading patterns within the rosy-faced lovebird (Agapornis roseicollis) across a range of experimental conditions to define the circumstances under which arboreal gaits are triggered, and how, during arboreal walking, gait patterns change across substrates of varying diameter. In so doing, we address longstanding questions as to how the challenges associated with arboreality affect gait parameters. Arboreal locomotion was associated with the adoption of a sidling gait, which was employed exclusively on the small and medium diameter poles but not terrestrially. When sidling, the hindlimbs are decoupled into a distinct leading limb (which imparts exclusively braking forces) and trailing limb (which generates only propulsive forces). Sidling was also associated with relatively low pitching forces, even on the smallest substrate. Indeed, these forces were significantly lower than mediolateral forces experienced during striding on terrestrial and large diameter substrates. We propose that the adoption of sidling gaits is a consequence of avian foot morphology and represents a novel form of arboreal locomotion where inversion/eversion is impossible. Such movement mechanics is likely widespread among avian taxa and may also typify patterns of arboreal locomotion in humans.

Parasitological and histopathological examination of Cocktail lovebirds infected with Eimeria aratinga (Apicomplexa: Eimeriidae).

Coccidiosis is a devastating worldwide disease and is considered a dreadful disease in lovebirds. Indeed, a problem has been appeared cocktail lovebirds kept in a private pet birdhouse in Sheikh Zayed City, Giza, Egypt, in the shape of blood-tinged diarrhea, birds huddled together and showing signs of inappetence, ruffled feathers, unable to fly, general weakness and emaciation associated with high mortalities. Therefore, this study aimed to diagnose and find a suitable treatment to overcome such problems. To achieve this aim, blood and droppings samples were collected from infected and healthy birds for parasitological and hematological examinations, and tissue samples were collected from freshly dead birds for postmortem and histopathological examinations. A treatment trial was adopted on 50 infected birds and 25 healthy and parasitological negative birds and groups were classified as follows: group 1) 25 infected birds treated with Diclazuril, group 2) infected birds treated with Coccicure, and group 3) 25 birds kept as control negative reference birds. The parasitological identification revealed the presence of Eimeria aratinga (E. aratinga) oocysts in the infected bird intestine. Finally, we concluded that E. aratinga is a serious protozoon parasite infesting lovebirds revealing severe clinical signs, high mortalities, histopathological changes in the intestine and alteration in blood parameters. Diclazuril is an effective drug in treating E. aratinga in cocktail lovebirds.

Characterization of agapornis fischeri interferon gamma and its activity against beak and feather disease virus.

This study sought to clone and sequence the interferon-γ (IFN-γ) gene of the Fischer's lovebird parrot (Agapornis fischeri). Raw264.7 cells treated with the expressed IFN-γ protein exhibited an upregulation in inducible nitric oxide synthase protein expression and nitric oxide (NO) production coupled with increases in phagocytosis and pinocytosis, as well as an induction of interferon-stimulated genes through the activation of the NF-κB factor, all of which are indicators of the innate immune responses of the activated macrophages. Similar to the IFN-γ protein of other species, the NO production activity of the parrot IFN-γ protein decreased by 80% after exposure at 60 °C for 4 min. Additionally, only half of the NO production activity of the parrot IFN-γ protein remained upon exposure to HCl for 30 min. These findings suggested that the parrot IFN-γ protein was heat-labile and sensitive to acidic conditions. Therefore, all of these effects contributed to the blockage of the uptake of BFDV virus-like particles (VLPs) by cells, the nuclear entry of the Cap protein of BFDV VLPs, and the clearance of the virus from BFDV-infected parrots by the IFN-γ protein of Agapornis fischeri. This study is the first to describe the cloning of the IFN-γ gene of Agapornis fischeri and characterize the anti-beak and feather disease virus activity of the IFN-γ protein of Agapornis fischeri.

Alfaxalone Sedation in Black-cheeked Lovebirds (Agapornis nigrigenis) for Non-invasive Procedures.

Alfaxalone is an injectable neuroactive steroid anesthetic that is becoming more widely used as a sedative in a wide range of animals. The purpose of this study was to evaluate the efficacy of this drug for sedation during handling and noninvasive medical procedures in black-cheeked lovebirds (Agapornis nigrigenis). Based on a pilot study that showed that 5 mg/kg alfaxalone was inadequate, and that 20 mg/kg resulted in respiratory arrest in 1 bird, the effects of 12.6 ± 0.9 mg/kg alfaxalone administered subcutaneously was investigated in 9 birds. Despite minor movements and twitching, it was possible to handle all birds and to perform positioning for a ventrodorsal radiograph. A loss of reaction to noxious stimuli was not achieved during sedation. Times from injection to initial effect (mean ± SD) was 93 ± 48 seconds; to recumbency, 209 ± 70 seconds; to first handling for positioning the bird in lateral recumbency, 251 ± 68 seconds; to initial righting effort, 55 ± 8 minutes; and to perching for a minimum of 20 seconds, 76 ± 7 minutes. Median respiration rates between 5 to 45 minutes were 36 to 40 breaths/min; apnea was not noted in any bird. Birds received 0.5 L of oxygen/min via face mask. Oxygen saturation (SpO2) and pulse rate were measured via pulse oximetry in 8 birds continuously from 10 to 30 minutes, SpO2 values remained above 90%. During sedation, mean pulse rate decreased significantly over time (P = .007; 10 minutes = 409 ± 81 beats/min; 30 minutes = 324 ± 25 beats/min). The majority of birds had rough inductions and recoveries, which could have been minimized if birds had been placed in a more confined space. In summary, 12.6 mg/kg alfaxalone provided nearly 1 hour of stable, nonanalgesic sedation appropriate for noninvasive procedures in black-cheeked lovebirds.

Cool birds: facultative use by an introduced species of mechanical air conditioning systems during extremely hot outdoor conditions.

Rapid climate change across the globe is having dramatic effects on wildlife. Responses of organisms to shifting thermal conditions often include physiological and behavioural accommodations, but to date these have been largely viewed and studied as naturally evolved phenomena (e.g. heat avoidance, sweating, panting) and not necessarily as strategies where animals exploit other anthropogenic conditions or resources. Moreover, the degree to which native versus introduced species show thermal plasticity has generated much conservation and ecological interest. We previously have observed introduced rosy-faced lovebirds (Agapornis roseicollis) perching in the relief-air vents on building faces in the Phoenix, Arizona, USA, metropolitan area, but doing so only during summer. Here, we show that such vent-perching events are significantly associated with extreme outdoor summer temperatures (when daily local highs routinely exceed 40°C). In fact, the temperature threshold at which we detected lovebirds starting to perch in cool air vents mirrors the upper range of the thermoneutral zone for this species. These results implicate novel, facultative use of an anthropogenic resource-industrial air-conditioning systems-by a recently introduced species (within the last 35 years) to cool down and survive extremely hot conditions in this urban 'heat-island' environment.

Development and characterization of microsatellite markers in Rosy-faced and other lovebirds (Agapornis spp.) using next-generation sequencing.

Agapornis are a group of small African parrots that are heavily traded around the world. They are invasive species in many places, but some of them are listed as Vulnerable or Near Threatened. However, the genetic tools for assessing inter-individual relationships, population structure, and genetic diversity of these birds are very limited. Therefore, we developed polymorphic microsatellite markers in A. roseicollis and tested the transferability on 5 lovebird species including A. personatus, A. nigrigenis, A. fischeri, A. pullarius, and A. canus, and two closely related outgroups (i.e. Bolbopsittacus lunulatus and Loriculus galgulus). We first performed whole-genome re-sequencing on five individuals of A. roseicollis to identify potential polymorphic loci. Out of 37 loci tested in 11 A. roseicollis, 27 loci were demonstrated to be polymorphic, with the number of the alleles ranging from 2 to 7 (mean = 3.963). The observed heterozygosity ranged from 0 to 0.875 (mean = 0.481) and expected heterozygosity ranged from 0.233 to 0.842 (mean = 0.642). Five loci (Agro-A13, p < 0.01; Agro-A15, p < 0.05; Agro-A43, p < 0.05, Agro-A65, p < 0.05; Agro-A67, p < 0.05) were detected to deviate from Hardy-Weinberg equilibrium, with the presence of null alleles suggested in locus Agro-A13 and Agro-A77. The exclusion powers for PE1 and PE2 are 0.997 and 0.999, respectively. The 27 novel polymorphic markers developed here will be useful for parentage and kinship assignment and population genetics study in Agapornis, and provide a tool for scientific research, captive breeding industry, and invasion and conservation management of these species.

Bilateral osteoma cutis in a Peach-Faced Lovebird (Agapornis roseicollis).

An osteoma is an infrequent tumor documented in avian species. An adult female Peach-Faced Lovebird (Agapornis roseicollis) with a history of previous trauma was examined due to the presence of bilateral hard and yellowish-white masses in the radio-cubital humerus junction. Histopathological dermal examination revealed a non-neoplastic process of mesenchymal origin, characterized by the formation of well-differentiated trabecular bone, multiple areas of medullary bone and loose connective tissue and coagulation of the necrosis foci. Based on the histological findings and the medical history, the masses were diagnosed as bilateral secondary osteoma cutis. To our knowledge, this is the first report of this pathology with an acute course in this exotic pet bird. The previous trauma could be the initiating cause.

Development of an SNP-based parentage verification panel for lovebirds.

The genus Agapornis, or lovebirds, are popular pet parrots worldwide. Currently, breeders are dependent on pedigree records as a selection tool as no molecular parentage verification test is available for any of the nine species. The A. roseicollis reference genome was recently assembled. This was followed by the sequencing of the whole genomes of the parents of the reference genome individual at 30× coverage. The parents' reads were mapped against the reference genome to identify SNPs. Over 1.6 million SNPs, shared between the parents, were discovered using the Genome Analysis Toolkit pipeline. SNPs were filtered to a panel of 480 SNPs based on Genome Analysis Toolkit parameters. The panel of 480 SNPs was genotyped in a population of 960 lovebirds across seven species. A panel of 262 SNPs was compiled that included SNPs successfully amplified across all species. The 262-SNP panel was reduced based on the observed heterozygosity (HO ) and minor allele frequency (MAF) values per SNP to include the lowest number of SNPs with the highest exclusion power for parentage verification. Two smaller panels consisting of 195 SNPs with MAF and HO values >0.1 and 40 SNPs with MAF and HO values >0.3, were constructed. The panels were verified using 43 families from different species with known relationships to evaluate the exclusion power of each panel. The 195 SNP panel with an average exclusion probability of 99.9% and MAF and HO values >0.1 was proposed as the routine Agapornis parentage verification panel.

How lovebirds maneuver through lateral gusts with minimal visual information.

Flying birds maneuver effectively through lateral gusts, even when gust speeds are as high as flight speeds. What information birds use to sense gusts and how they compensate is largely unknown. We found that lovebirds can maneuver through 45° lateral gusts similarly well in forest-, lake-, and cave-like visual environments. Despite being diurnal and raised in captivity, the birds fly to their goal perch with only a dim point light source as a beacon, showing that they do not need optic flow or a visual horizon to maneuver. To accomplish this feat, lovebirds primarily yaw their bodies into the gust while fixating their head on the goal using neck angles of up to 30°. Our corroborated model for proportional yaw reorientation and speed control shows how lovebirds can compensate for lateral gusts informed by muscle proprioceptive cues from neck twist. The neck muscles not only stabilize the lovebirds' visual and inertial head orientations by compensating low-frequency body maneuvers, but also attenuate faster 3D wingbeat-induced perturbations. This head stabilization enables the vestibular system to sense the direction of gravity. Apparently, the visual horizon can be replaced by a gravitational horizon to inform the observed horizontal gust compensation maneuvers in the dark. Our scaling analysis shows how this minimal sensorimotor solution scales favorably for bigger birds, offering local wind angle feedback within a wingbeat. The way lovebirds glean wind orientation may thus inform minimal control algorithms that enable aerial robots to maneuver in similar windy and dark environments.

[Human Psittacosis: A Case Report]. / Psitacose: A Propósito de Um Caso Clínico.

Psittacosis is a rare disease caused by Chlamydophila psittaci, an intracellular bacteria transmitted by contaminated birds. The clinical and radiological presentations are nonspecific. We describe a case of a 42-year-old woman, with known exposure to birds, who presented to the emergency department with one-week evolution of myalgia, polyarthritis, and respiratory symptoms. At admission, she had fever, respiratory failure, raised inflammatory markers and bilateral interstitial infiltrates at chest radiography. Considering the clinical findings and epidemiological background, we raised the hypothesis of a Chlamydophila psittaci atypical pneumonia that was serologically confirmed. Tetracyclines are the mainstay of treatment and the macrolides are an effective alternative. We highlight the importance of the epidemiological context in the early diagnosis and treatment of this infection.

A psitacose é uma entidade rara provocada pela Chlamydophila psittaci, uma bactéria intracelular obrigatória que se transmite através do contacto com aves contaminadas. A apresentação clínica e imagiológica é inespecífica. Reporta-se o caso clínico de uma mulher de 42 anos, com história de exposição a pássaros, que se apresenta no Serviço de Urgência com um quadro de mialgias, poliartralgias e clínica de infeção respiratória, com uma semana de evolução. À admissão, encontrava-se febril, com insuficiência respiratória do tipo 1, elevação dos parâmetros inflamatórios e infiltrados intersticiais difusos bilaterais na radiografia de tórax. Considerando o quadro clínico e o contexto epidemiológico de risco, colocou-se a hipótese de pneumonia atípica por Chlamydophila psittaci, confirmada serologicamente. As tetraciclinas são o esteio do tratamento, sendo os macrólidos uma alternativa eficaz. Realça-se a importância do contexto epidemiológico, para uma abordagem diagnóstica e terapêutica apropriadas.

Agapornis sp. pet birds: Source of dissemination of azole-resistant yeasts.

The objectives of this study were to identify yeasts in 40 feces samples of Agapornis birds and determine their antifungal susceptibility profile by two methodologies. Results indicated 92.5% of positivity (46 isolates). Six genera were identified (14 species): Cryptococcus (39.13%), four species; Candida (36.96%), four species; Rhodotorula (13.05%), two species; Trichosporon (6.52%), two species; Kodamaea ohmeri (2.17%); and Sporobolomyces salmonicolor (2.17%). Regarding the susceptibility profiles, 41.3% of the isolates showed low sensibility to fluconazole and 47.8% to itraconazole. Thus, Agapornis sp. disseminate potentially pathogenic and resistant yeasts. Precautionary measures should be taken regarding breeding and keeping them as pets.
