They also cause different types of infections, and different types of antibiotics are effective against them. There are many other stains besides Gram stain. Shapes: All bacteria may be classified as one of three basic shapes: spheres (cocci), rods (bacilli), and spirals or helixes (spirochetes).

When cholera symptoms occur, they begin 1 to 3 days after exposure, usually with sudden, painless, watery diarrhea and vomiting. Usually, people have no fever.

Abstract. After De’s pivotal demonstration in 1959 of a diarrhoeogenic exo-enterotoxin in cell-free culture filtrates from Vibrio cholerae (of classical biotype), much insight has been gained about cholera toxin (CT), which is arguably now the best known of all microbial toxins. The subunit structure and function of CT, its receptor (the GM1 ...

It affects both children and adults and can kill within hours. It has a short incubation period, ranging between two hours and five days. People with low immunity, such as malnourished children or people living with HIV ...
Shedding of hyperinfective bacteria in patient stool is predicted to impact the epidemic spread of cholera by lowering the infectious dose required to cause disease. Transcriptional profiling of V. cholerae isolated from patient stool revealed that genes required for nutrient acquisition and motility were upregulated, while genes required for ...
