The study aimed to identify potential biomarkers of mammary gland infection in Santa Inês sheep. Commercial flocks of sheep provided the same hygiene, sanitary, and nutritional management under semi-intensive production systems were monitored during the lactation stage-and assessed 15, 30, 60, and 90 days after delivery (through the end of lactation and weaning). The California Mastitis Test (CMT) was performed on the mammary glands. Milk was collected for bacterial examination and protein analysis. Bacterial culture and biochemical characterization of the samples were performed. Forty-two milk samples from healthy glands (negative CMT and bacterial testing) and 43 milk samples from infected glands (positive CMT and bacterial testing) taken at the predefined time points were assessed. A rennin solution was used to obtain the whey. The proteins analysis was performed using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), which allowed for the quantification of nine whey proteins produced in healthy glands: serum albumin, lactoferrin, IgA, IgG heavy-chain (IgG HC), IgG light-chain (IgG LC), total IgG (IgG HC + IgG LC), ?-lactalbumin, ?-lactoglobulin, protein with MW 15.000 Da, protein with MW 29.000 Da and eleven whey proteins secreted by infected glands, including haptoglobin and ?-1-acid glycoprotein. A comparison of whey proteins between healthy and infected glands showed increases (P<0.05) in the secreted and total contents of all proteins, except for IgG LC and ?-lactoalbumin. The most significant changes were observed in ?-1- acid glycoprotein, lactoferrin and haptoglobin, which showed three-, five-, and seven-fold increases in secretion, respectively. This study showed that haptoglobin, ?-1-acid glycoprotein, lactoferrin, albumin, and the IgA and IgG immunoglobulins may serve as potential biomarkers for mammary gland infection in sheep.

Fruit flies (Diptera: Tephritidae) are among the main pests in horticulture, impacting field crops and export markets. The biological control of fruit flies has become an important method for environmentally friendly crop production. Although biological control is an age- old practice and the mass- rearing of some biological agents boomed in the 1990s, efforts in fruit fly control programs still face several challenges. We conducted a systematic review to investigate publications assessing the success or failure of using natural enemies against tephritid fruit flies. Our goal was to compile and summarize information from over 30 years of research on biocontrol efforts, including groups and species of control agents and fruit flies tested, methodological approaches applied, the country where the study was performed, and the scope adopted. We also analyzed effectiveness, efficiency, and success rates in biocontrol studies published from 1990 to 2021. Our review showed 2986 records, of which 225 publications matched the criteria. The most- studied biocontrol agents for the suppression of fruit flies were parasitoids, fungi, and nematodes. A few studies assessed bacteria, predators, and viruses. We found a total of 55 fruit fly species described as hosts of the biological agents. Natural/conservation biological control was the main scope studied; however, augmentative biological control had a higher rate of successful studies and potential success, followed by classical biological control. The effectiveness and efficiency parameters are discussed to provide support for researchers in future studies.
