“…Isolate of Streptococcus equi subsp. zooepidemicus was susceptible to cephalosporin and all penicillins used, except ampicillin, corroborating previous research of Pansani et al, 2016 that detected in equine samples 100% of the isolates of the subspecies sensitive to penicillin, 40% resistant to ampicillin, however 35% presented resistance to cefotaxime, differently our study (Table 1). The S. zooepidemicus strain showed resistance to norfloxacin and sensitivity to ciprofloxacin (both belonging to the fluoroquinolone class), in addition to MDR.…”

There are several infectious diseases that affect equines and can cause large economic losses in this sector and damage to animal welfare. In this species, abscessing lesions of a purulent character preferentially in the withers are strongly suggestive of brucellosis. However, few studies have been carried out on the disease in this species, making its identification and control difficult due to the lack of standardization in the interpretation of results. Therefore, samples of whole blood, serum and purulent secretion were collected from three horses. The animals came from the state of Pará. The diagnostic methods selected were the Rose-Bengal plate test (RBPT) and Polymerase Chain Reaction (PCR), for the negative molecular results for brucellosis, microbiological analysis were chosen. Although part of the samples were positive for brucellosis in serological tests, all of them showed negative results for PCR. In bacterial cultivation, species were isolated Streptococcus equi subsp. zooepidemicus, Enterococcus faecalis e Staphylococcus sciuri subsp. lentus., which showed resistance to antibacterials, especially the E. faecalis isolate classified as MDR (multi drug resistant). In conclusion, the best form of diagnosis is the joint evaluation of several tests, both screening and confirmatory, in order to obtain a definitive diagnosis with assertiveness.

“…In clinical cases of strangles, horses show the typical clinical signs of a generalized infectious process (depression, lack of appetite, fever), as well as nasal secretion, initially serous, which changes to mucopurulent and purulent in some days, productive cough, pain on palpation the mandibular region and an increase in the volume of lymph nodes, mainly submandibular, in addition to the extended neck position due to pain in the larynx and pharynx region (Moraes et al, 2009). The presumptive diagnosis is performed according to the clinical signs, with the gold standard being the bacterial culture with the identification of S. equi (Pansani et al, 2016;Ribas et al, 2018).…”

Respiratory diseases have a major impact on sport horses and are often cited as the second most common reason for loss of training days and significant veterinary costs. Adult horses most commonly develop pneumonia when bacteria aspirated from the environment, nose, or oropharynx reach the lower airways and overwhelm the pulmonary defense mechanisms. This article report five cases of bacterial pneumonia in horses associated with infection by Eschericia coli. Five Quarter horses, three males and two females, with ages varying from 5 to 12 years, were examined for diagnosis of respiratory disease characterized by apathy, cough and lack of appetite. Auscultation of the thorax revealed increased harsh breath sounds dorsally, crackles, wheezes, and dullness of respiratory sounds ventrally. Manipulation of the trachea and larynx induced cough. Culture results were positive for Escherichia coli. The therapeutic protocol consisted of anti-inflammatory, antibiotic therapy, and supportive care. Flunixin meglumine was administered intravenously at 24-hour intervals over eight days. Ceftiofur sodium was prescribed intramuscularly, q.d., for 15 days. Horses were clinically monitored daily until complete remission of clinical signs. None of the animals relapsed, and all returned to routine athletic activities.

“…Mesquita et al (2019) relataram elevada resistência (próximo a 100%) frente à β-lactâmicos, licosaminas e aminoglicosídeos. Assim como Pansani et al (2016) descreveram resistência de 63% à tetraciclina e Manzoor et al (2008) sugeriu índice de 100% de resistência à tetraciclina.…”

O uso da antibioticoterapia em animais, na maioria das vezes, ocorre de maneira desorientada, o que colabora para o aumento da resistência microbiana. Neste contexto, o presente trabalho teve por objetivo avaliar a prevalência de bactérias multirresistentes na cavidade nasal de equinos assintomáticos para doenças respiratórias. Foram coletadas amostras de swab nasal de 50 equinos assintomáticos para doenças respiratórias. As amostras foram semeadas em placas de Petri contendo ágar sangue e ágar MacConkey, incubadas em aerobiose e microaerofilia a 37ºC por 48 horas. As culturas puras foram submetidas à identificação segundo as características morfocoloniais, morfotintoriais e bioquímico-fisiológicas convencionais. Também foi realizada a verificação da susceptibilidade antimicrobiana in vitro e em seguida calculado o índice de resistência múltipla. Das amostras analisadas foram isolados Staphylococcus aureus, Staphylococcus coagulase negativa, Streptococcus spp, Micrococcus spp, Enterobacter spp e Escherichia coli. O gênero Staphylococcus e Streptococcus demonstraram resistência total e intermediária a praticamente todos os antibióticos testados; o gênero Enterobacter aos β-lactâmicos, cefalosporinas, monobactam, quinolonas, anfenicóis, sulfozamidas, e aminoglicosídeos (amicacina e tobramicina); e E. coli aos β-lactâmicos, algumas cefalosporinas, monobactam, quinolonas, aminoglicosídeos, anfenicóis, sulfozamidas e tetraciclina. Todas as cepas analisadas apresentaram multirresistência. Conclui-se que equinos hígidos sem alteração respiratória, possuem microrganismos com potencial patogênico em suas fossas nasais. Além disso, o alto índice de resistência microbiana é preocupante e serve de alerta para o possível uso indiscriminado de antibióticos, o qual pode afetar a saúde animal e dos seres humanos.
