Abstract
Trueperella pyogenes is a pathogenic bacterium that causes suppurative infections in domestic and wild animals as well as humans. This paper describes a clinical case of subcutaneous abscess by T. pyogenes in a bovine in the Western Amazon, Brazil. During anamnesis, intramuscular injectable drug administration in the middle third of the left gluteal biceps muscle and the practice of reusing needles were reported. The clinical examination revealed edema, hyperthermia and high pain sensitivity to the touch in the region. A sample was collected through a puncture incision for the bacterial culture, during which T. pyogenes was isolated. The therapeutic approach was the use of a systemic antimicrobial and topical care, with a good prognosis. This report is the first description of infection by T. pyogenes in cattle in the Western Amazon and underscores the importance of appropriate sanitary management in herds, especially the use of disposable needles and hygiene at the site of parenteral drug application.
Highlights
INTRODUCTIONT. pyogenes may be found in the oral, nasal and genital microbiota of apparently healthy ruminants and pigs (ROGOVSKYY et al, 2018; GALÁN-RELAÑO et al, 2019)

The evolution of the disease is related to cases of mastitis, arthritis, interdigital phlebitis, osteomyelitis, abortion, metritis, orchitis, omphalitis and bronchopneumonia as well as subcutaneous abscess or abscess in parenchymal tissues, with a variable prognosis (CAFFARO et al, 2014; ISHIYAMA et al, 2017; WARETH et al, 2018; KONTTURI et al, 2019; PIERSANTI et al, 2019)
Summary
T. pyogenes may be found in the oral, nasal and genital microbiota of apparently healthy ruminants and pigs (ROGOVSKYY et al, 2018; GALÁN-RELAÑO et al, 2019). It is present in the environment and can be found in fomites. This paper describes a clinical case of subcutaneous abscess by Trueperella pyogenes in a bovine in the Western Amazon. A sample of the content was sent to the Animal Infectious Disease Laboratory of the Federal University of Acre for bacteriological isolation in 5% bovine blood agar at 37°C for 48 hours in aerobiosis. Based on the pertinent literature, the phenotypic and biochemical characteristics were compatible with Trueperella pyogenes (MEGID; RIBEIRO; PAES, 2016; ROGOVSKYY et al, 2018)
