“…Another famous explorer, La Perouse, like his contemporary Captain Cook, was making a The author is affiliated t with the U.S. Geological Survey, Washington, D.C., in the Branch of Paleontology and Stratigraphy. scientific expedition around the world when both of his frigates, the Astrolabe and the Boussole, were lost, in 1788, on the dangerous outer reefs of Vanikoro in the Santa Cruz Islands (4).…”

Neonatal Sulfhemoglobinemia and Hemolytic Anemia Associated With Intestinal Morganella morganii

“…It has been postulated that in the absence of sulfur-containing drugs, the source may be from H 2 S produced as a metabolic end product by intestinal microbiota capable of reducing sulfate or elemental sulfur. 4,13,14 Retrospectively, fecal samples were subjected to microbiota compositional analysis via Illumina MiSeq sequencing where we noted the presence of M morganii. This species represented 38% of the relative abundance in the fecal microbiota of our subject, whereas it was completely absent in a control group and was observed to reduce to 3% abundance while the infant was recovering.…”

“…1,3 The majority of cases are attributed to exposure to sulfurcontaining drugs, but SHb has also been postulated to be derived from hydrogen sulphide (H 2 S) produced by the intestinal microbiota. 4,5 We present a case of sulfhemoglobinemia and hemolytic anemia in a 7-day-old infant, who fortunately survived this potentially lethal condition, in addition to our efforts to identify the source of H 2 S.…”
