kolhapur
Mechanisms of renal injury (Depending on the species and strain/ on the host’s resistance and genetic background)
Direct invasion of the renal parenchyma
Induce an immune reaction
Injure the capillary endothelium
Provoke a nonspecific humoral hematologic response.

Postinfectious / Poststreptococcal glomerulonephritis
Streptococcus pyogenesGram negative cocci
Complication -streptococcal pharyngitis / impetigo
Immune complexes- lodged in the glomerular basement membrane
Complement activation leading to basement membrane destruction
Disorder of the glomeruli or small blood vessels in the kidneys.
Pyelonephritis
.
Escherichia coli Gram negative bacilli
Pyelonephritis -type of urinary tract infection (UTI) that affects one or both kidneys.
Route- from the bladder/ through the bloodstream from other parts of the body.

Filaria
Wuchereria bancrofti
Mode of Infection-mosquito bite
Definitive host-manIntermediate host-Mosquito(culex,Aedes,Anopheles)

Recurrent infections associated with damaged lymphatic abnormalities of therenal functions.
LeishmaniasisLeishmania donovani
Mode of transmisson-bite of sandfly(Phlebotomus)
Definitive host-ManIntermediate host-sandfly
Infective form-Promastigote
Cloudy swelling of kidney-albuminuria
Amastigote form
Promastigote
Schistosomiasis (Bilharziasis)
Schistosoma mansoni, S. haematobium,S.japonicum.
Source of infection - contaminated freshwater
Infective form – cercariae
Definitive host -humansIntermediate host-Snail
Renal granulomas
Echinococcosis (hydatid cyst)
Echinococcus granulosus
Mode of infection - contaminated food and drinkInfective agent - embryonated eggs.
Definitive host - dogIntermediate host – man
Glomerulonephritis
Toxoplasmosis
Toxoplasma gondii
Mode of infection-Uptake of cyst byinhalation, followed by ingestion .
Infective form-cyst
Primary host – cat
Intermediate host - human
Disseminated infection of Kidney occurs
Trichinosis
Trichinella spiralis
Mode of transmission - raw or undercooked pork bearing larvae
Proliferative glomerulopathy
Onchocercosis
Onchocerca volvulus
Mode of infection-bite of black flies
Definitive host-ManIntermediate host-female black flies(simulium)
Infective form-larvae
Progressive glomerulonephritis.
Fungal diseases
Disseminated Candidiasis
Mucormycosis
Ochratoxicity
Disseminated Candidiasis
Candida species
Predisposing factor - immunocompromised persons,leukemic patients undergoing high-dose chemotherapy.
Perinephric abscess
Renal failure
Mucormycosis
Mucor, Rhizopus, Absidia, and Cunninghamella Occurs in underdeveloped tropical regions
Immunocompromised patients
Renal infarction and thrombosis of renal vessels.
Ochratoxicity
Group of mycotoxins produced by some Aspergillus sp. and some Penicillium sp. Occur in commodities such as cereals, coffee, dried fruit and red wine
Toxic-Nephropathy
Carcinogenic
Viral infections
Dengue haemorrhagic fever
Hepatitis A
Hepatitis B
Hepatitis C
Dengue haemorrhagic fever
.
Dengue virus (DEN-1–DEN-4)RNA flavivirus.
Dengue vector - female of the Aedes aegypti
GlomerulonephritisAcute kidney injury (AKI)Haemolytic uraemic syndrome
Hepatitis A
RNA Virus
Source of infection - Faeces
Route of transmission - Fecal-oral
kidney inflammation.
Hepatitis B
DNA Virus
Source of infection- Blood/blood derived bodyfluid
Route of transmission- :
Parenterallylow verticalsexual transmission
Renal necrosis occurs due to the body’s reactionto the virus rather than due to the virus itself.
Hepatitis C
RNA virus
Source of infection-Blood/blood derivedbody fluid
Route of transmission Parenterally low vertical sexual transmission
Renal carcinoma
