The aim of this study was to identify chemical markers of commercial tropical red wines with the potential to apply for the Geographical Indication-GI São Francisco Valley. Volatile organic compounds of nine diferent commercial red wines from the São Francisco Valley, located in the Caatinga region of Brazil, that meet the classic oenological parameters for commercialization, were extracted and separated by the HS-SPME/GC?MS technique, and identifed. A total of 103 volatile compounds were identifed and classifed into 13 chemical groups, of which the esters and alcohols were the majority groups. Similarities were found in the composition of 27 compounds identifed in all wines; however, the cultivars infuenced the distinction of volatiles expressed exclusively in only one type of wine. Among these, 22 compounds were highlighted for having been identifed for the frst time in wines, such as 3-phenyl-undecane and 4-phenyl-decane. These exclusive compounds are possible markers which confrm the typicality of tropical red wines of this region, and can contribute to the qualitative description and enhancement of regional identity for wines from the São Francisco Valley.

The aim of this study was to determinate whether coagulase-negative staphylococci (CNS) from buffalo milk or the milking environment possess virulence factors that are associated with intramammary infections or antimicrobial resistance. Milk samples (n = 320) from 80 lactating buffalo were evaluated for clinical and subclinical mastitis by physical examination, the strip cup test, California Mastitis Test (CMT), and somatic cell count (SCC) over a 4-mo period. In addition, swabs were obtained from the hands of consenting milkers (16), liners (64), and from the mouths (15) and nostrils (15) of buffalo calves. No clinical cases of mastitis were observed; however, CMT together with SCC results indicated that 8 animals had subclinical mastitis. Eighty-four CNS isolates were identified by MALDI-TOF MS and cydB real-time PCR (qPCR) and then evaluated by qPCR for presence of the eta, etb, sea, sec, cna, seb, sei, seq, sem, seg, see, and tst toxin genes, adhesion- and biofilm-associated genes (eno, ebps, fib, fnbA, coa), and the methicillin resistance gene (mecA). Resistance to antibiotics commonly used for mastitis treatment in Brazil was determined using the Kirby-Bauer test. Two strains were positive for the see and eta toxin genes; and mecA (1), eno (27), ebps (10), fnbA (10), and coa (5) genes were also detected. A notable number of isolates were resistant to erythromycin (30), penicillin (26), and cotrimoxazole (18); importantly, 10 vancomycin-resistant isolates were also detected. A smaller number of isolates were resistant to rifampicin (8), oxacillin (7), clindamycin (5), cefepime (4), tetracycline (3), ciprofloxacin (2), and chloramphenicol (1), and none were resistant to gentamicin or ciprofloxacin. Isolates with resistance to 2 (13 isolates), 3 (3), 4 (3), 5 (1), and 6 (1) antibiotics were detected. Taken together, our findings suggest that CNS isolates may not be a significant cause of clinical or even subclinical mastitis in buffaloes, but they may be a reservoir of virulence and antibiotic resistance genes.
