Name of disease Caused byParts of body affectedMethod of spreadType of vaccination or antibodies
DiphtheriaCorynebacterium diphtheriaUpper respiratory tract, mainly throat also toxin affects heart.Droplet infectionToxoid
Tuberculosis (TB)Mycobacterium tuberculosisMainly lungsDroplet infection, Drinking milk from infected cattle.BCG living attenuated bacteria. Antibiotics e.g. streptomycin.
Whooping cough (Pertussis)Bordetella pertussisUpper respiratory tract, inducing violent coughingDroplet infectionKilled bacteria
GonorrhoeaNeisseria gonorrhoeaeReproductive organs: mainly mucous membranes of urinogenital tract. Newborn infants may acquire serious eye infections if they pass through infected birth canal.Contagion by sexual contactAntibiotics, e.g. penicillin, streptomycin
SyphilisTreponema pallidumReproductive organs, then eyes, bones, joints, central nervous system, heart and skin.Contagion by sexual contactAntibiotics. e.g. penicillin
TetanusClostridium tetaniBlood. Toxin produced which affects motor nerves of spinal cord and hence muscles, causing lockjaw and spreading to the muscles.Wound infectionToxoid
CholeraVibrio choleraAlimentary canal: mainly small intestine.Faecal contamination (a) food – or water borne of material contaminated with faeces from infected person. (b) handling of contaminated Objects. (c) vector, e,g. flies moving from human faeces to food.Killed bacteria: short-lived protection and not always effective Antibiotics e.g. tetracyclines, chloramphenicol.
Typhoid feverSalmonella typhiAlimentary canal, then spreading to lymph and blood, lungs, bone marrow, spleen.Same as choleraKilled bacteria (TAB vaccine)
Bacterial dysenteryShigella dysenteriaeAlimentary canal, mainly ileum and colonSame as choleraNo vaccine.
Bacterial food poisoning (gastro enteritis or salmonellosis)Salmonella spp.Alimentary canalMainly foodborne meat from infected animals from poultry and pigs. Also via faecal contamination as choleraAntibiotic. e.g. tetracyclines.
