INTRODUCTION • Infectious Disease in animals & human • Caused by Salmonella • Food Borne Disease (eggs, milk and meat products) • Animals Decrease of production Enteric Disease Abortus and neonatal death • Fowl High Mortality rate (DOC up to 2 – 3 weeks of age)
Etiology • Salmonella road shape cell, Gram negative, non spore, somatic (O) & flagellar (H) antigens • Salmonella are usually motile except in poultry S. gallinarum & S. pullorum, do not ferment lactose. • Growth optimal in MCA, SSA • The genus Salmonella contains more than 2.400 serotypes, occur worldwide and infect many mammals, birds and reptiles and are mainly excreted in faeces.
Epizootiology Salmonellosis is a worldwide zoonosis, besides economic losses to animal production, its zoonotic character makes it an important public health problem. Organism may be present in water, soil, animal feeds,raw meat and in vegetable material. The source of environtmental contamination is faeces In poultry S. pullorum infect the ovaries, and the organisms can be isolated from eggs.
Pathogenesis Although many aspects of the pathogenesis of Salmonellosis are poorly understood, the virulence of Salmonellae relates to their ability to invade host cells, replicate in them and resist both digestion by phagocytes. Peroral tract. Intestinalis (mucosae of the illeum, caecum and colon) and the messenteric lymph nodes replicate and LPS product endotoxin it may be contribute to the local inflammatory response which damages intestinal epithelial cells diarrhoea organisms can be excreted through faeces Bacterial cell wall LPS also mediates the endotoxic shock septicaemic salmonellosis Latent infections, in which Salmonellae are present in the gall bladder but are not excreted.
Clinical Symptom • Clinical disease may develop from subclinical and latent infections if affected animals are stessed e.g transportation, overcrowding etc. • Salmonellosis in adult cattle is usually sporadic and is also often associated with stress. • In most animals species, both enteric and septicaemic forms of salmonellosis are recorded. • Enteric salmonellosis : • Acute disease is characterized by fever, depression, anorexia and profuse diarrhoea often containing blood, mucus and epithelial casts. Dehydration and weight loss follow and pregnant animals may abort.
Chronic disease : • Can follow acute Salmonellosis in pigs, cattle and horses are characterized by : intermittent fever, soft faeces and gradual weight loss, emaciation. • Septicaemic Salmonellosis : • Clinical disease is sudden with high fever, depression, and die within 48 hours. • Surviving animals can develop persistent diarrhoea, arthritis, meningitis or pneumonia. • Pigs characteristic bluish discolouration of the ears and snout.
Salmonellosis in poultry S. pullorum Pullorum disease S. gallinarum Fowl typhoid S. enteritidis in egg dishes may result in human food poisoning PULLORUM DISEASE = Bacillary White Diarrhoae Infects young chicks and turkey poults up to 2 – 3 weeks age and the mortality rate is high The clinical symptoms are anorexia, depression, whitish faecal pasting around their vents and characteristic lessions include whitish nodes throughout the lungs and focal necrosis of liver and spleen. FOWL TYPHOID Lession in young chicks and poults similar of Pullorum Disease Characteristic findings bile-stained liver and enlarge spleen.
Differentiation of the biotypes of S. pullorum and S. gallinarum : S. pullorum S. gallinarum Glukose (gas) + - Dulcitol - + Maltose - + Ornithine decarboxylase + - Rhamnose + - Motility - -
Diagnosis • A history of previous outbreaks of the disease, clinical sign and postmortem picture. • Laboratory confirmation is required Specimens : faeces, blood, intestinal contents, tissue lession and abomasal contents ( aborted foetuses ) - Isolation and identification specimen should be cultured onto SSA, BGA and also added to Selenite F, Tetrathionate broth for enrichment. - Serrological tests Rapid Whole Blood Test (RWBT) for Pullorum Test with Polyvalent antigen or ELISA and DNA probes.
Treatment • Antibiotic therapy should be based on results of susceptibility testing • Oral antimicrobial therapy should be used judiciously for treating enteric salmonellosis • Fluid and electrolyte replacement therapy is required to counteract dehydration and shock
Control • Measures for excluding infection form a herd or flock free of salmonellosis • Measures for reducing environmental contamination
