(HUS) happens once microorganisms enter the system and release a poisonous substance that destroys red blood cells. Patients with hemolytic uremic syndrome often have dysentery. The syndrome is deadly (Galanakis et al., 2002; Butler, 2012).
Enterococcus is the massive group of carboxylic acid microorganism of the phylum Firmicutes. Enterococci are Gram +ve cocci that generally occur in pairs (diplococci) or short chains. Enterococci are facultative anaerobic organisms, i.e., they're capable of internal respiration in each oxygen-rich and oxygen-poor environment. Although they're not able of forming spores, enterococci are tolerant of a large vary of environmental conditions: hot temperature (10–45 °C), pH (4.5–10.0), and high …show more content…

Proteus bacilli are widely distributed in nature as saprophytes, being found in moldering animal matter, sewage, manure soil, the mammalian intestine, and human and animal body waste. They are opportunistic pathogens, commonly responsible for urinary and septic infections. The urinary tract infections involving struvite stones are characteristic. By producing urease, Proteus spp. can hydrolyze urea into ammonia and carbon dioxide, and therefore raise urinary pH. Alkalinization of urine promotes precipitation of magnesium-ammonium phosphate salts leading to the formation of struvite stones, which may serve as a nidus for the persistence of infection or may directly obstruct the urinary tract, there by promoting infection. Proteus is often the cause of bacterial invasion of the bloodstream often associated with diabetes, heart and lung disease, or cancer. Proteus is regarded to be an undesired element of intestinal microflora, as the bacteria may also become a causative agent of diarrhea. Approximately 95% of UTIs occur when bacteria ascend through the urethra and the bladder. Infection includes Urethritis, cystitis, prostatitis, or pyelonephritis. Chronic, recurring stones may be an indication of chronic infection. Symptoms of urethritis are usually mild and may be dismissed by the patient. Women present with dysuria, pyuria, and increased frequency of urination. Presenting symptoms in males are usually mild and may include urethral discharge. Symptoms of cystitis tend to be more prominent compared to those of urethritis. In both men and women, symptoms are of sudden onset. They include dysuria, increased frequency, urgency, suprapubic pain, back pain, small volumes, concentrated appearance, and hematuria. If the patient is febrile, this could be a sign of bacteremia and impending sepsis. These symptoms may not be present if the patient has an indwelling catheter. Prostatitis is obviously limited to men and occurs
