[The physicochemical and biological characteristics of the Yersinia pestis pH 6 antigen isolated by an immunosorption method] Bacteriostasis of Y. pestis(but not enteropathogenic yersiniae) was abrupt in Ca2+-deficient medium at neutral to slightly alkaline pH (7.0 to 8.0), although increasing the pH to 8.5 or 9.0, especially with added Na+(but not l-glutamate), facilitated full-scale growth After migrating to the inside of macrophages, Y. pestis bacteria would encounter harsher microenvironments, including higher temperature, low pH values, osmotic pressure, and reactive oxygen species (as shown in Figure 1). Consequently, Y. pestis may have evolved the ability to adapt to these challenges

Yersinia pestis is a nonmotile, slow-growing, facultative organism classified in the family Enterobacteriaceae. It appears as plump, gram-negative coccobacilli that are seen mostly as single cells or pairs, which may exhibit bipolar staining from a direct specimen if stained with Wright's or Giemsa stains. This appearance has been referred to as safety pin-like Y. pestis was discovered in 1894 by Alexandre Yersin, a Swiss/French physician and bacteriologist from the Pasteur Institute, during an epidemic of the plague in Hong Kong. Yersin was a member of the Pasteur school of thought Description and significance Yersinia pestis was discovered in Hong Kong in 1894 by a Swiss physician Alexandre Yersin, who was a student of the Pasteur school of thought.

Yersinia pestis is a bacterial pathogen that causes bubonic plague in humans. As Y. pestis cycles between fleas and mammals, it senses the environment within each host to appropriately control gene expression. PsaA is a protein that forms fimbria-like structures and is required for virulence. High temperature and low pH together stimulate psaA transcription by increasing the levels of two. Plague is a widespread zoonotic disease that is caused by Yersinia pestis and has had devastating effects on the human population throughout history. Disappearance of the disease is unlikely due to the wide range of mammalian hosts and their attendant fleas Yersinia pestis Provider Requirements Isolate Submission REQUIRED.

Yersinia pestis and plague: an updated view on evolution

The fraction 1 (F1) capsule of Yersinia pestis, the causative agent of plague, is a highly antigenic, virulence-associated surface structure (2, 28).The capsule, encoded by the caf gene cluster (Fig. 1A), has antiphagocytic activity and decreases uptake by macrophages and epithelial cells (7, 17).Capsule biogenesis occurs via the conserved chaperone/usher (CU) pathway (24, 27) and is dependent. Pneumonic plague occurs when Yersinia pestis infects the lungs. Transmission can take place if someone breathes in Y. pestis particles, which could happen in an aerosol release during a bioterrorism attack. Pneumonic plague is also transmitted by breathing in Y. pestis suspended in respiratory droplets from a person (or animal) with pneumonic.
