Bovine mastitis is an important and costly disease to dairy cattle. Diagnostic methods usually performed in Brazil are somatic cell counts (SCC) and milk microbiology. Low bacteria shedding in milk implies no colony growth in microbiological tests and false negative results. Streptococcus agalactiae and Staphylococcus aureus are principal pathogens of mixed mastitis. However, S. agalactiae has a higher bacterial release from the mammary gland than S. aureus, affecting microbiological sensitivity to diagnose S. aureus. This study aimed to estimate the SCC and total bacterial count (TBC) from cows according to pathogen isolated in milk and to evaluate variation in S. aureus diagnosis by a microbiological test during S. agalactiae treatment, which is called blitz therapy. Both S. agalactiae and S. aureus presented high SCC means, although S. agalactiae showed shedding of bacteria 2.3 times greater than S. aureus. Microbiological sensitivity to S. aureus increased for 5 months during S. agalactiae treatment. The prevalence of S. agalactiae fell after 5 months of therapeutic procedures. The prevalence of S. aureus increased to 39.0. The results showed that due to high sensitivity, the polymerase chain reaction (PCR) could be used at the beginning of blitz therapy with the goal of S. agalactiae eradication from the dairy herd.

Definida como um dos maiores desafios do século XXI, a pandemia de covid-19 atingiu os 5 continentes do mundo. O objetivo desta pesquisa foi conhecer a percepção dos usuários do Hospital Militar de Ladário, MS, quanto aos conceitos epidemiológicos e às medidas de prevenção comunicados pelas mídias. Trata-se de um estudo qualiquantitativo transversal. Os resultados apontaram para um ambiente favorável à difusão da informação por mídias sociais e aplicativos de mensagens. Evidenciou-se que o público jovem tem mais acesso à internet e aos aplicativos de mensagens, como WhatsApp; 98% dos respondentes acreditam na importância da troca de informações, 43,5% obtêm informações a partir das mídias sociais e menos de 1% prefere receber informações por e-mail. É de grande relevância a divulgação da informação em saúde para públicos distantes da sede, de forma a manter elevada a prevenção da doença e a preservação da vida.

Most antimicrobials used globally in human medicine are also employed in animal treatment, increasing the risk of antimicrobial resistance. In this context, the World Health Organization (WHO) and the World Organisation for Animal Health (WOAH) classified antimicrobials according to their importance in human and veterinary health. This study analyzed the antimicrobial molecules commercially available in Brazil for animal use, comparing their classifications based on WHO and WOAH criteria. Data was collected by consulting the Business Intelligence panel of the Ministry of Agriculture and Livestock (MAPA). A total of 742 registered drugs were identified, comprising 70 distinct antimicrobial molecules, totaling 888 occurrences in different drug formulation combinations. Among these molecules, 55.2% were considered Highly Important Antimicrobials (HIA) by the WHO, while 85.5% were categorized as Critically Important Veterinary Antimicrobial Agents (VCIA) by the WOAH. Divergences in classifications between the organizations were observed, highlighting potential challenges for veterinarians in clinical decision-making.
