“…However, in 1993, a colleague of Prof. Mazza published a letter to the editor [88], in which he corrected the issue of transmission of T. cruzi with breast milk. Jörg [90] corrected that the milk collected by Mazza et al [88] was contaminated with blood, indicating that transmission of T. cruzi was via blood (bleeding nipples). Similar results related to the transmission of T. cruzi via nipple digestion were presented by Mediana-Lopez [91].…”

One of the most important bioactive components of breast milk are free breast milk oligosaccharides, which are a source of energy for commensal intestinal microorganisms, stimulating the growth of Bifidobacterium, Lactobacillus, and Bacteroides in a child’s digestive tract. There is some evidence that maternal, perinatal, and environmental-cultural factors influence the modulation of the breast milk microbiome. This review summarizes research that has examined the composition of the breast milk microbiome and the factors that may influence it. The manuscript highlights the potential importance of the breast milk microbiome for the future development and health of children. The origin of bacteria in breast milk is thought to include the mother’s digestive tract (entero-mammary tract), bacterial exposure to the breast during breastfeeding, and the retrograde flow of breast milk from the infant’s mouth to the woman’s milk ducts. Unfortunately, despite increasingly more precise methods for assessing microorganisms in human milk, the topic of the human milk microbiome is still quite limited and requires scientific research that takes into account various conditions.

“…Because T. cruzi, originally named Schyzotrypanum cruzi, possesses the capacity to cross the epithelium and to infect via the oral route [29,327,329], the presence of this pathogen in the milk has been searched for. T. cruzi was found in the milk of experimentally infected mice [328,330,331], and several reports describe the presence of this pathogen in the milk from pregnant women [332][333][334][335], as reviewed by Norman and Lopez-Vélez [336]. In most cases, the presence of T. cruzi in the milk of pregnant women has been attributed to contamination by infected blood due to nipple bleeding [336].…”

Unicellular eukaryotes of the Trypanosomatidae family include human and animal pathogens that belong to the Trypanosoma and Leishmania genera. Diagnosis of the diseases they cause requires the sampling of body fluids (e.g., blood, lymph, peritoneal fluid, cerebrospinal fluid) or organ biopsies (e.g., bone marrow, spleen), which are mostly obtained through invasive methods. Body fluids or appendages can be alternatives to these invasive biopsies but appropriateness remains poorly studied. To further address this question, we perform a systematic review on clues evidencing the presence of parasites, genetic material, antibodies, and antigens in body secretions, appendages, or the organs or proximal tissues that produce these materials. Paper selection was based on searches in PubMed, Web of Science, WorldWideScience, SciELO, Embase, and Google. The information of each selected article (n = 333) was classified into different sections and data were extracted from 77 papers. The presence of Trypanosomatidae parasites has been tracked in most of organs or proximal tissues that produce body secretions or appendages, in naturally or experimentally infected hosts. The meta-analysis highlights the paucity of studies on human African trypanosomiasis and an absence on animal trypanosomiasis. Among the collected data high heterogeneity in terms of the I 2 statistic (100%) is recorded. A high positivity is recorded for antibody and genetic material detection in urine of patients and dogs suffering leishmaniasis, and of antigens for leishmaniasis and Chagas disease. Data on conjunctival swabs can be analyzed with molecular methods solely for dogs suffering canine visceral leishmaniasis. Saliva and hair/bristles showed a pretty good positivity that support their potential to be used for leishmaniasis diagnosis. In conclusion, our study pinpoints significant gaps that need to be filled in order to properly address the interest of body secretion and hair or bristles for the diagnosis of infections caused by Leishmania and by other Trypanosomatidae parasites.

“…Mazza et al ( 5 ) reported transmission through lactation; in the other study, the newborn was not breast-fed ( 28 ). However, another publication later indicated that in the study by Mazza et al, the collected milk was contaminated by blood ( 29 ). Medina-Lopes reported 2 cases of acute Chagas disease in infants that had been acquired through breast-feeding from mothers in the chronic phase.…”
