Leptospira noguchii is a gram-negative, pathogenic organism.L noguchii is famous for causing the febrile illness in Fort Bragg, NC during World War II. There was 40 cases of this fever documented during each summer from 1942 to 1944; however, there were 0 deaths recorded from this outbreak. Unlike other strains of Leptospira that cause leptospirosis, L. noguchii is characterized by showing a pretibial rash on the victim.
Leptospira noguchii was originally cultured in 1907, but was thought to be Spirochaeta interrogans due to the question mark shape of the cell. However, upon further research on the 16s rRNA Yasuda et al. was able to classify this organism as Leptospira noguchii.
Originally, there were only two species classifications of Leptospira. They were categorized as Leptospira interrogans, the pathogenic species, and Leptospira biflexa, the nonpathogenic species. However in 1989, it was discovered that there were 21 different species of Leptospira. Within these 21 species, Leptospira noguchii was recognized. However, conjugation is very common among the genetic materials making them hard to distinguish individual species.
Leptospira noguchii can grow in stagnant water, and is known to grow optimally between 28 °C - 30 °C at a pH between 7.2 and 7.6.L. noguchii is also known to have a parasitic relationship and grow in host’s kidneys. It can be isolated from urine, blood, and cerebrospinal fluid.
