Pig farming is an area of livestock that has been developing the most in Brazil and the world, with production increasing every year, generating jobs, and being of great importance for the Brazilian economy. In swine production, great health enables these animals to reach their highest point of development and antimicrobials are used, either prophylactically or through food, as growth promoters. Within swine culture, there is a concern regarding antibiotic-resistant bacteria; however, Staphylococcus spp. do not receive the necessary prominence in research, since the pathologies caused by them do not tend to cause great economic losses. Therefore, this review aimed to highlight the importance of bacterial resistance within breeding stock, its possible origins, the importance of Staphylococcus spp. within this topic, and its evolution in swine farming over the years. For this, studies were selected, with an emphasis on information such as country, number of samples, presence of Staphylococcus spp. resistant to methicillin, breeding phase, and phenotypic and molecular tests. In addition, publications were selected that show the importance of understanding the biological and resistance profiles of Staphylococcus spp. in swine herds in Brazil and around the world.


A suinocultura é uma das áreas da pecuária que mais se desenvolveu e se desenvolve no Brasil e no mundo, com a sua produção aumentando todos os anos, gerando empregos diretos e indiretos, e sendo de grande importância para a economia brasileira. Destaca-se na produção de suínos a necessidade de grande sanidade para que estes animais alcancem seu maior ponto de desenvolvimento e, para tal, são utilizados antimicrobianos, seja de forma profilática ou através da alimentação, como promotores de crescimento. Dentro da suinocultura também está presente a preocupação envolvendo as bactérias resistentes a antibióticos, contudo, os Staphylococcus spp. não recebem o destaque necessário em pesquisas, já que as patologias causadas por estes ainda não tendem a causar grandes prejuízos econômicos de forma direta aos produtores. Por este motivo, esta revisão objetivou evidenciar a importância da resistência bacteriana dentro dos planteis, suas possíveis origens, a importância dos Staphylococcus spp. dentro deste tópico e a sua evolução na suinocultura através dos anos. Para este foram selecionados trabalhos encontrados em diferentes bases de dados com ênfase em informações como país, número de amostras, presença de Staphylococcus spp. resistentes a meticilina, fase de criação, e testes fenotípicos e moleculares, além de publicações que evidenciam a importância de se conhecer os perfis biológicos e de resistência dos Staphylococcus spp. nos planteis de suínos do Brasil e do mundo.

Background: Anophthalmia is a rare, congenital condition, defined as the complete absence of the eye bulb due to inadequate growth of the vesicle or optic dome. The malformation can be primary (in the absence of complete), secondary (inthe presence of only residual tissue), or degenerative (in which the eye begins to form, but for some reason, it begins todegenerate). This condition is rare in dogs, cats, cattle, and sheep. Microscopic evaluation of orbital tissue for identificationis always recommended. The aim of this study was to report a case of bilateral anophthalmia in a domestic cat.Case: A feline male, healthy, Maine Coon breed with 60 days of life was attended at the one veterinary private clinic.The cat, negative for FIV and FeLV, was born in a commercial cattery, belonging to his mother’s third litter, healthy litterwith the exception of this feline. He arrived with a complaint of not opening his eyelids, like the rest of the litter. In theclinical examination, it was found the normality of vital signs, absence of other visible anatomical abnormalities, only theocular region was observed with closed eyelids. The initial suspicions were anophthalmia and microphthalmia. The patientwas referred for an ocular ultrasound, which showed the complete absence of the right and left eye bulbs. The right andleft orbital cavities had only a volume of soft, amorphous, and predominantly homogeneous tissue. After the ultrasoundreport, the patient underwent a surgical procedure to remove a fragment of tissue from the eye socket, which was sent forhistopathological examination to confirm anophthalmia and discard the differential diagnosis of microphthalmia. Microscopy revealed immature, epithelial, and glandular tissue in the middle of discrete and moderate connective tissue, looselyarranged. In some fragments, cartilaginous tissue was also revealed. Thus, the histological findings are...

Background: Contact between humans and pets, mainly dogs and cats, has been increasing in recent years, which may result in the spread of infectious agents to new hosts and even to the environment, causing emergencies of national and international interest. The aim of this work was to understand the phenotypic profile of bacteria of the Enterobacteriaceae family of vaginal and preputial mucous of stray dogs from a border region. Materials, Methods & Results: Swab samples from the vaginal and preputial mucosa of stray dogs from two border regions were collected for later bacterial isolation, biochemical identification of bacterial isolates, susceptibility tests to different antimicrobials, and determination of the bacterial resistance index. Samples were collected from 70 animals, was possible to isolate 88 samples, of which 36 (40.9%) presented isolates of Gram-negative bacteria, with Escherichia coli being the most prevalent species (44.8%), followed by Obesumbacterium proteus in eight (27.5%); Enterobacter aerogenes and Enterobacter cloacae in two (6.8%); and Erwinia herbicola, Koserella trabulsii, Proteus mirabilis, and Serratia rubidaea (3.4%) from one isolate. The most resistant antimicrobials Clindamycin (100%), Metronidazole (100%), Oxacillin (100%), and Penicillin (100%) were tested against the vaginal and preputial samples and when the multidrug resistance index of the isolates was analyzed, all were classified as presenting a public health risk. Discussion: The results of this work suggest that stray dogs may be considered potential reservoirs of resistant pathogenic microorganisms, enabling future health problems due to the close coexistence of tutors with their dogs. It is known that the microorganisms that inhabit a certain environment or a specific part of the body are collectively called microbiomes. More specifically, some of them are bacteria that inhabit the reproductive mucous...
