Query: NC_011083:3171171 Salmonella enterica subsp. enterica serovar Heidelberg str. SL476, Lineage: Salmonella enterica; Salmonella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria General Information: This is a multidrug resistant strain. Salmonella enterica subsp. enterica serovar Heidelberg is one of the more common serovars causing disease in the USA. This group of Enterobactericiae have pathogenic characteristics and are one of the most common causes of enteric infections (food poisoning) worldwide. They were named after the scientist Dr. Daniel Salmon who isolated the first organism, Salmonella choleraesuis, from the intestine of a pig. The presence of several pathogenicity islands (PAIs) that encode various virulence factors allows Salmonella spp. to colonize and infect host organisms. There are two important PAIs, Salmonella pathogenicity island 1 and 2 (SPI-1 and SPI-2) that encode two different type III secretion systems for the delivery of effector molecules into the host cell that result in internalization of the bacteria which then leads to systemic spread.

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.
