Query: NC_002940:1234410 Haemophilus ducreyi 35000HP, complete genome

Lineage: Haemophilus ducreyi; Haemophilus; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria

General Information: This strain is a human passage derivative of Haemophilus ducreyi strain 35000 that is serum-resistant. Causative agent of chancroid. A group of organisms that are either obligate parasites or commensal organisms found in animal mucous membranes. Almost all species require the presence of important growth factors found in the blood of their hosts, including either X factor (protoporphyrin IX or heme) or V factor (nicotinamide adenine dinucleotide (NAD or NADP)). This organism is an obligate human pathogen that causes the sexually transmitted disease chancroid (ulcer of the genital region) and it enhances the transmission of HIV (which enhances Haemophilus ducreyi transmission in turn). This organism is an apparent extracellular pathogen that resists phagocytosis. Some of the virulence factors include an outer membrane serum resistance protein, as well as two toxins, cytolethal distending toxin (CDT) and hemolysin, both of which contribute to tissue destruction.

Subject: NC_020064:3517500 Serratia marcescens FGI94, complete genome

Lineage: Serratia marcescens; Serratia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This organism was discovered in 1819 by Bizio who named the organism after the Italian physicist Serrati. It was considered a nonpathogenic organism until late in the 20th century, although pathogenicity was noted as early as 1913. Serratia marcescens is an opportunistic human pathogen that is increasingly associated with life-threatening hospital-acquired infections. It is an environmental organism that has a broad host range, and is capable of infecting vertebrates and invertebrates, as well as plants. In humans, Serratia marcescens can cause meningitis (inflammation of the membrane surrounding the brain and spinal cord), endocarditis (inflammation of heart muscle) and pyelonephritis (inflammation of the kidneys). Many strains are resistant to multiple antibiotics. Environmental isolates are noted by production of the red pigment prodigiosin.
