INFECTION DISEASE AND SPREADING
Spreading of microorganisms in the body Cell expansion
The spread of Salmonella typhi to intestinal cells,
staphylococci and streptococci found in the deep, tuberculosis agents in the liver lesions
Spreading with phagocytic cells
Metastatic event in tuberculous cases Spread through blood
B. abortus and C. fetus subsp. Fetus (spread)
P. multocida (both propagation and reproduction) Lymphatic spread
Francisella tularensis, Corynebacterium pseudotuberculosis ovis
Nervous spread Rabies virus
INFECTION DISEASE AND SPREADING
Pathways of Microorganisms from Body to Body Through the skin
Flower virus, Marek's disease virus, Anthrax effect, glander effect, skin tuberculosis effect
Through the respiratory system Droplet infection
Through the digestive system
Stool and vomiting (Helicobacter felis, H. pylori) Through the urogenital system
Urine - Corynebacterium renale, Leptospira species
Genital outflows - Mycoplasma species, Haemophilus somnus, abort factors
By way of release
Milk - mastitis agents, B. abortus, B. melitensis, L. monocytogenes Tears - M. bovis, M. conjunctivae, cattle virus
INFECTION DISEASE AND SPREADING
Contaminant Shapes of Microorganisms
Vertical transmission (Intra-uterine transmission) Hereditary Contagion - Retroviruses (RNA viruses) Congenital infection
Germinal infection (S. pullorum, S. gallinarum, M. galliseptium, Newcastle disease, Avian Encephalomyelitis, EDS'76
viruses, H. somnus)
Placental transmission (Blue-tongue disease virus, cat panleukopeni virus)
Immediate transmission (C. jejuni)
Horizontal (Lateral) infection (Extra- or post-uterine infection) Direct and indirect transmission
INFECTION DISEASE AND SPREADING
Contaminant Shapes of Microorganisms Direct contamination
Direct physical contact (fungal infections, anthrax, staphylococcus, etc.)
Venereal transmission (C. fetus subsp venerealis) Fecal - oral infection (Salmonellosis)
Droplet infection or air-borne infection Indirect infection
Iatrogenic transmission (surgical intervention, therapeutic applications)
Infection with inanimate intermediates (fomit)
Contamination by vital agents (reservoir and vector)
