incisions, skin abrasions, Mucous
membrane ,Ear, Sebum channels.
 Transmitted by direct contact, endogenous
infection, Swimming water , hot tubes etc.

5.  Impetigo –Staphylococcus aureus or Streptococcus

 Folliculitis-Staphylococcus aureus
 Toxic shock syndrome-Staphylococcus aureus
 Necrotizing fasciitis- Streptococcus pyogenes
 Erysipelas-Streptococcus pyogenes
 Dermatitis-Pseudomonas aeruginosa
 Otitis externa-Pseudomonas aeruginosa
 Acne-Propionibacterium acnes

8.  Fever , rash, shock
 Tissue destruction
 Reddish patches
 Inflammatory lesions
 Infection of hair follicle
 Vesicles on skin

9.  For pseudomonas -
fluoroquinolones, and
self limiting
 For propionibacterium -
benzyol peroxide, isotr -
etinoin, azelaic
• For Staphylococcus aureus- penicillin, beta-lactom
antibiotic
• For streptococcus -penicillin ,surgical remove of
tissue

10.  Caused by Papillomavirus, smallpox, monkey
virus, Varicella zoster virus, Herpes simple virus
type 1,6 and 7, Measles virus, Rubella virus,
Human parvovirus.
 Enters in skin by respiratory track, endogenous
infection of peripheral nerves, mucous membranes
etc.
 Transmitted by contact, aerosol, recurrence of
latent chickenpox , recurring latent infection etc.

13.  Warts
 Smallpox
 Monkeypox
 Chickenpox
 Shingles
 Herpes simplex
 Measles
 Rubella
 Fifth disease (erythema infectiosum)
 Roseola

14.  Horny projection of the skin formed by proliferation
of cell
 Pustules that may be nearly confluent on skin
 Vesicles are confined to face, throat and lower back,
waist, scalp, upper chest ,around mouth.
 skin rashes of reddish maculae's first appearing on
the face and spreading to trunk and extremities
 Mild macular disease with facial rash

15.  Removed by liquid nitrogen cryotherpay,
electrodessication , acids or lasers.
 Acyclovir , preexposure to vaccine etc.

16.  Caused by Microsporum, Trichophyton,
epidermophyton spp, Sporothrix and
Schenckii , Candida albicans .
 Enters in by skin ,skin abrasion, mucous
membranes etc.
 Transmitted by direct contact ,soil
,endogenous infection etc.

17.  Ringworm
 Sporotrichosis
 Candidacies

18.  Skin lesions of highly varied apperaance,
loss of hair.
 Ulcer at site of infection spreading into
neraby lymphatic vessels
 Infected skin becomes bright red

19.  Griseofulvin , Miconazole, Clotrimazol
 Potassium iodide , Ketoconazole

20.  Caused by Sarcoptes scabiei and Pediculus
humanus capitis etc.
 Present on skin
 Transmitted by contact

21.  Scabies and Pediculosis
 Forms papules and itching
 Treated by Gamma benzene hexachloride ,
permethrin and by topical insecticide
preparation.

22.  Types of skin infections are Bacterial, Fungal, Viral
and parasitic.
 Disease transmitted by direct contact, soil, infection
, aerosols etc.
 Portal of enrty is skin ,hair folicles, surgical incision,
ear ,sebum channel, repiratory track, endogenoous
infection, mucous membrane etc.
 Symptoms are different for different infection.
 Treatment for virus , bacteria ,fungi and parasitic is
different.
