Resumo: O experimento foi realizado com o objetivo de estudar, em ovinos mantidos em pastagens de capim-buffel, a utilização de leucena ou guandu, como bancos de proteína, durante estação seca. Foram testados nove tratamentos experimentais, constituídos pela combinação de três tipos de pastagens (capim-buffel, capim-buffel+guandu e capim-buffel+leucena), com três taxas de lotação (4, 6 e 10 borregos/ha). As pastagens, em duas repetições, foram estabelecidas em dezoito piquetes de 0,5 ha. Foram utilizados 60 borregos, com peso médio inicial de 19,4 kg, que receberam água e suplementação mineral completa à vontade e foram pesados a intervalos de 14 dias após 16 horas de jejum. Na pastagem de capim-buffel+leucena, foi possível elevar a lotação de quatro para seis borregos/ha, sem redução do ganho individual de peso dos animais, com conseqüente aumento da produção por unidade de área. Na pastagem de capim-buffel+guandu, não houve melhoria de desempenho dos animais em comparação à pastagem de capim-buffel. Concluiu-se que bancos de proteína de leucena podem melhorar a qualidade de pastagens de capim-buffel.

Abstract: The experiment was carried out to evaluate the use of Leucaena leucocephala and Cajanus cajan as protein sources, during the dry season for lambs grazing on buffel grass pastures. Nine experimental treatments resulting from the combination among three types of pasture (buffel grass, buffel grass+Cajanus cajan, and buffel grass+leucaena) and three stocking rates (4, 6 and 10 lambs/ ha) were tested. Eighteen paddocks (two replicates of pastures per treatment) of 0.5 ha were used. Sixty lambs with 19.4 kg live weight at the beginning of the experiment were allocated to pastures with water and mineral supplement offered ad libitum. Animal liveweight was recorded at 14 day-intervals after 16 hours of fasting. Lambs on the pasture of buffel grass+leucaena showed good performance with no variation in daily liveweight gain rate, when the stocking rate increased from 4 to 6 animals/ha. Buffel grass+Cajanus cajan pasture did not improve animal performance as compared to buffel grass pasture. It was concluded that leucaena, used as protein supplement, can improve the quality of buffel grass pastures.

Surgical environment can play as a source of multidrug-resistance organism, what can pose as a big threat to the patients and health care professionals. This study aimed to evaluate the prevalence and antimicrobial resistance profile of Gram-positive cocci (GPC) and Gram-negative bacilli (GNB) isolated from the surgical environment. All samples were collected during the intraoperative period of clean/clean-contaminated (G1) and contaminated (G2) surgery. A total of 150 samples were collected from the superficial surgical site in the beginning (n = 30) and the end (n = 30) of the procedure, surgeon's hands before (n = 30) and after (n = 30) antisepsis, and the surgical environment (n = 30). MALDI-TOF MS and antimicrobial susceptibility testing by disk diffusion method were performed for species identification, and determination of the resistance profile. Sixty-eight isolates of GPC and 15 of GNB were obtained. Staphylococcus spp. were the most frequent species isolated from surgical site (55.26% [21/38]), surgeon's hands (46.15% [6/13]), and environment (56.67% [17/30]). GPC were mostly resistance to penicillin (85.71% [54/63]), and erythromycin (77.78% [49/63]), and GNB were mostly resistance to cefazolin (58.33% [7/12]), and azithromycin (58.33% [7/12]). High incidence of multidrug resistance was observed in coagulase-negative staphylococci (86.21% [25/29]), coagulase-positive staphylococci (86.67% [13/15]), Enterococcus spp. (68.42% [13/19]) and Gram-negative bacilli (60% [9/15]). The high rate of resistance of commensal bacteria found in our study is worrying. Coagulase-negative staphylococci are community pathogens related to nosocomial infections in human and veterinary hospitals, their presence in healthy patients and in veterinary professionals represent an important source of infection in the One Health context. Continuous surveillance and application of antimicrobial stewardship programs are essential in the fight against this threat.
