Gastroenteritis bacterial

In children suffering from gastroenteritis due to bacterial infection, there was a negative correlation between the magnitude of fever and the duration of the infection.

The spectrum of gastrointestinal tract infections (GTI) cover a wide spectrum from asymptomatic Helicobacter pylori gastritis to self-limiting viral gastroenteritis to food poisoning to bacterial enterocolitis to antibiotic-associated Clostridium difficile colitis to typhoid fever with sepsis and multi-organ failure. 

Campylobacter species are most commonly responsible for outbreaks of bacterial gastroenteritis in developed countries. The majority of die gastrointestinal Campylobacter infections do not require antibiotic treatment and are selflimiting. Where treatment is required, erythromycin is usually recommended. However, fluoroquinolones are often also used pending laboratory results, because they can cover additional bacterial pathogens and are better tolerated than erythromycin. 

Experimental work with bacterial cells presents a potential biohazard. Some strains of the bacteria recommended for use may cause gastroenteritis (abdominal pain and diarrhea). Do not pipet any solutions by mouth. Always wear gloves and wash your hands well with hot water and soap before eating or drinking. 

Salmonella enterica (S. enterica) is a rod-shaped Gram-negative facultative anaerobe and a prominent enteric bacterial pathogen capable of causing food- and water-related diseases. Several serovars of S. enterica are associated with human infection. The principle clinical diseases associated with Salmonella infection are typhoid fever and gastroenteritis. S. enterica serovars Typhi S. Typhi) and Paratyphi (,S. Paratyphi) are pathogenically exclusive for humans and are known to cause typhoid or enteric fever (Ohl and Miller, 2001). Typhoid fever is a systemic infection characterized by the development of fever, abdominal pain, enterocolitis, and occasionally, a maculopapular rash. The hallmark feature of typhoid fever is the presence of mononuclear cell infiltration and hypertrophy of the intestinal Peyer s patches and mesenteric lymphoidal tissue (Kraus et al., 1999 Ohl and Miller, 2001). There are approximately 20 million cases of typhoid fever worldwide each year, and this acute and often life-threatening infection is responsible for over 200,000 deaths annually (Crump et al., 2004).

Campylobacter jejuni Gram-negative bacterium, v hich is one of the most frequent causes of bacterial gastroenteritis world-wide. Campylobacter jejuni gastroenteritis is the most frequently recognized preceding infection in GBS. 

Secondary lactose intolerance may occur as a result of reduced enzyme activity following diffuse intestinal damage from infections (giardiasis, bacterial overgrowth, or viral gastroenteritis), ulcerative colitis, celiac disease, and tropical sprue. This deficiency is usually reversible following recovery from the disorder. 

The side effects inherent to some of these drugs used as lifelong treatment must be taken into account. Also, reduced gastric acidity eliminates a natural physical protective barrier and may cause, with continuous use, bacterial overgrowth [91] and gastroenteral infections [92]. This would be especially problematic for cystic fibrosis patients, who, because of the nature of their disease, are more susceptible to intestinal infections. 

Hemolysins, which lyse vertebrate erythrocytes, are important virulence factors in vertebrate bacterial pathogens. Such toxins are also found in some Bt strains and seem to be identical to the hemolysin found in B. cereus. Some Bt isolates have been found to produce the same type of diarrhea-producing enterotoxins as B. cereus. Bt may therefore have implications in causing gastroenteritis.
