6. Glander’s disease
7. Cat scratch disease

Tuberculosis
• well know phrase
• The more the things change, the more they remain
same
• This applies to tb which is a wide spread infectious
disease seen from centuries
• Chronic bacterial infection caused by
Mycobacterium tuberculi characterized by the
formation of granulomas in infected tissue by cell
mediated hypersensitivity

•M.tuberculosis is a rod
shaped
•Nonsporing
•Thin aerobic bacteria
• ACID FAST BACILLI
•acid fastness is due to high
content of mycolic acids ,
• long chain crosss linked
fatty acids and other cell
wall lipids
Causative org:
Myc. TB
Myc.Bovis
Myc.avium intercellulare
Causative org:
Myc. TB
Myc.Bovis
Myc.avium intercellulare

ETIOLOGY
• M.tb facultative intra cellular parasite
• Human strain is responsible for many cases
• bovine strain - illness through the ingestion of
unpasteurised cow’s milk .
• Rarely atypical or oppurtunistic mycobacteria -
pulmonary or generalised infection in
immunocompromised individuals

Mode of transmission :
1. Inhalation of organism
2. Ingestion of organism
3. Inoculation of organism
4. Transplacental route

Clinical features:
- Episodic fever, chills & night sweats
- Fatigue & malaise
- Loss of weight
- cough with or without hemoptysis
classification
Depending on extent of bacterial exposure &
resistance of the patient
- Asymptomatic primary TB
- Symptomatic primary TB
- Progressive primary TB &
- Reactivation TB

PRIMARY TB
 The infection of an individual who has not been
previously infected or immunized is called
Primary TB or Ghon’s complex.
 Tissue involved is lung & hilar lymph nodes,
tonsils, cervical lymph nodes.
 Ghon’s complex consists of 3 components:
1. Pulmonary component
2. Lymphatic vessel component
3. Lymph node component

GHON’S FOCUS

FATE OF PRIMARY TB
1. Fibrosis, calcification & ossification
1. Progressive primary tuberculosis
1. Primary miliary tuberculosis – seen in liver, spleen,
kidney, brain, bone marrow.

SECONDARY TB
 The infection of an individual who has been
previously infected and sensitized is called
secondary or post primary or reinfection or chronic
tuberculosis.
 Sec. TB occurs in lungs, tonsils, pharynx, larynx,
small intestine &skin.
 Infection acquired from
1. Endogenous source
2. Exogenous source

FATE OF SECONDARY TB
 Fibrosis & calcification
 Progressive pulmonary
TB.
1. Fibrocaseous TB
2. Tuberculous caseous
pneumonia
3. Miliary TB

SCROFULA

 Female genitalia : Abdominal pain, vaginal disorders,
menstrual disorders.
 Meningitis : cranial nerve palsies, hydrocephalus,
blindness, optic atrophy.
 Skin : Lupus vulgaris

ORAL MANIFESTATIONS
 Oral mucosa has rarely been reported
 Age :Children and adolescents
 Sex : Male :female :: 5:1

• Primary TB : gingiva, tooth extraction sockets,
buccal folds
• Sec. TB : tongue, palate, lips, alveolar mucosa &
jaw bones
• Lesions present as ulcers or less commonly as
nodules, vesicles, fissures,, plaques, granulomas
and verrucous proliferations.
• Lesion may be single or multiple, painful or
painless

• Mucosa :Ulcer – irregular, ragged, undermined
edges, minimal induration , with yellowish
granular base
• Tongue
 Site : lateral border, ant. Dorsum, base of tongue
 Painful, grayish-yellow, firm well demarcated

TUBERCULOSIS - ULCERS

• Tooth apex & socket involvement: Brodsky &
Klattel - 1943
• Jaw bone involvement: Tuberculous
osteomyelitis

paraesthesia of lower lip, lymphadenopathy
 Loosening of teeth.
 TB of maxilla
• Involvement of major salivary glands:
 Parotid gland followed by submandibular and
sublingual glands
(Zheng &Zhang –1995, Mignogna et al – 2000)

INVESTIGATIONS
• Examination of sputum
• Bacterial culture
• Radiographs
• Mantoux test
 False negatives : Severe TB, AIDS, recent
infection,malnutrition, malignancy, sarcoidosis.
 False positive : infection by related bacteria

CALCIFIED CERVICAL LYMPH NODES

• Culture of Mycobacterium tuberculosis
remains the gold standard for both diagnosis
and drug sensitivity testing.
• Conventional culture methods using
Lowenstein-Jensen (LJ) or 7H11 medium,
• disadvantage of being very slow. take 20 – 56
days for diagnosis
• four to six weeks after initial culture for drug
sensitivity testing.
• .

• 7H11- medium slightly accelerates the
process, but requires antibiotics in the
medium to prevent contamination and a CO2
incubator.
• Diagnosis with 7H11 medium takes 17 –21
days,
• DST information is available three to six
weeks later

Ptosis seen in neuro syphilis

Portrait of Gerard de
Lairesse ( 1665–67). De
Lairesse, himself a painter
and art theorist, suffered
from congenital syphilis
that severely deformed his
face and eventually blinded
him.
Congenital syphilis

• T.p – has ability to cross placental barrier
• Fetus infected during 2nd,3rd trimester

HUTCHINSONS INCISOR

Saber shin

Actinomycosis
• Actinomycosis is a suppurative and granulomatous
chronic infectious disease
• usually spreads into adjacent soft tissues without
regard for tissue planes or lymphatic drainage
• may also be associated with a draining sinus tract
• Caused by ray fungus a.israelli, a.nalesundi,
a.viscosus, a.odontolyticus, a.propionica
• A.bovis produce lumpy jaw

• Actinomyces are Gram-positive, non-acid fast, anaerobic or
microaerophilic filamentous branched bacteria
• living as commensal organisms in the human oral cavity and
respiratory and digestive tracts,
• Becoming invasive when, through a mucosal lesion, they
gain access to the subcutaneous tissue.
• Infection is always endogenous. Doesnot occur by person
to person contact.
• Thus, dental caries, dental manipulations and
oromaxillofacial traumas are the most common triggering
events

• Presents as a chronic, fluctuant mass
• Located at the border of the mandible
• pain is rare, slight fever
• sensation of superficial tension around the mass.
• Initially, the mass may be surrounded by induration
or erythema; later, it may become tender to
palpation, on account of a central necrosis process
• Becoming progressively larger within weeks or
months

• Mass breaks down and abscess, sinuses are formed
• Discharging pus contain typical yellow sulphur
granules
• Skin overlying abscess is purplish,red indurated has
appearance of wood.
• Infection may extend into adjoining soft tissue as
well as bone
• Leads actinomycotic osteomyelitis

CERVICO FACIAL ACTINOMYCOSIS

• Definitive diagnosis may be established only by a
positive culture, however, Actinomyces growth is
very difficult even on appropriate anaerobic media
• The macroscopic presence of the classic sulfur
granules in tissue specimens or drainage may be of
some help when making diagnosis, even if these
features are not pathognomic, since nocardiosis,
botryomycosis may also present with sulfur granules

• Surgery plays an important role both in the diagnosis
and treatment of actinomycosis,
• recurrence following surgery alone is very common
• 2-4 weeks of high-dose intravenous antibiotics
followed by 3-6 months of oral antibiotics.
• Penicillin is the drug of choice
• Tetracycline and erythromycin are employed in
patients allergic to penicillin.

• Begins as small ulcer on gingival mucosa
• Rapidly spreads & involves surrounding tissues
• Jaws, lips, cheeks
• Initial site is commonly an area of stagnation around
fixed bridge or crown
• Overlying skin becomes inflammed, edematous, necrotic
• Line of demarcation develops between healthy and dead
tissue

appearance of blackening of skin
• Large masses of tissue may slough, leaving jaw
exposed
