Despite the effectiveness of some drugs, the disease remains a major worldwide problem. Consequently, the search for new treatments is important for disease eradication. Biological molecules with antimicrobial properties represent a promising alternative to combat pathogens. Bovine lactoferrin (bLF) is a key component of the innate host defense system, and its peptides have exhibited strong antimicrobial activity. Based on these properties, we evaluated the parasiticidal activity of these peptides on G. intestinalis. Trophozoites were incubated with different peptide concentrations for different periods of time, and the growth or viability was determined by carboxyfluorescein-succinimidyl-diacetate-ester (CFDA) and propidium iodide (PI) staining. Endocytosis of peptides was investigated by confocal microscopy, damage was analyzed by transmission and scanning electron microscopy, and the type of programmed cell death was analyzed by flow cytometry. Our results showed that the LF peptides had giardicidal activity. The LF peptides interacted with G. intestinalis and exposure to LF peptides correlated with an increase in the granularity and vacuolization of the cytoplasm. Additionally, the formation of pores, extensive membrane disruption, and programmed cell death was observed in trophozoites treated with LF peptides. Our results demonstrate that LF peptides exhibit potent in vitro antigiardial activity. <\/jats:p>","DOI":"10.1139\/bcb-2016-0079","type":"journal-article","created":{"date-parts":[[2016,11,30]],"date-time":"2016-11-30T22:41:24Z","timestamp":1480545684000},"page":"82-90","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":31,"title":["Parasiticidal effect of synthetic bovine lactoferrin peptides on the enteric parasite <i>Giardia intestinalis<\/i>"],"prefix":"10.1139","volume":"95","author":[{"given":"Hugo","family":"Aguilar-Diaz","sequence":"first","affiliation":[{"name":"CIASaP, Facultad de Medicina, Universidad Aut\u00f3noma de Sinaloa.
