There is more than 4 folds increase in the titer of antibodies against Salmonella typhi “320/40= 8”, this means acute infection.

Escherichis coli

Infection:-

1- urinary tract infection

2- diarrhea

Treatment:-

requires antibiotic testing, but most common are

1-”Ampicilin”

2-”Aminglycosides”

Klebsiella

Infection:-

urinary tract infection

Treatment:-

beta lactamase producing

“Aminglycosides” is used

Proteus

Infection:-

urinary tract infection, by the urease the urea is split to produce ammonia “alkaline urine”

Salmonella

Infection:-

1- typhoid fever

2- food poising “meat, poultry & egg” diarrhea

This usually happens when people eat in public places “Pakistan, Sudan & Egypt”

Treatment:-

In enteric fever “chloramphenicol”, if resistant “ciprofloxacilin”

Shigilla

Infection:-

dysenteriae (enterotoxin, cytotoxic & neurotoxic) bloody, mucoid & small stools with fever

Treatment:-

Fluid replacement & “Ampicillin”

Vibrio cholera

Infection:-

cholera (exotoxin persistent and excessive secretion of isotonic fluid by intestinal mucosa)

Treatment:-

“Erythromycin”

Campylobacter jejuni

Infection:-

Food poisoning “Chicken” diarrhea.

Treatment:-

“Erythromycin”

Helicobacter pylori

Infection:-

Gastric and duodenal ulcerations

Treatment:-

Triple therapy: “Omeprazole” + “Amoxycilin” + “Metronidazole”

Quadruple therapy: Same + proton pump inhibitors

Infection:-

Gastric and duodenal ulcerations

Treatment:-

“Erythromycin”, “Amoxycilin”
