The common blood feeder mites of poultry are from the genera Dermanyssus and Ornithonyssus. Their presence are problematic for the producers either through potential direct effects on weight gain, egg production or sperm production in roosters or as nuisance pests on workers. They also cause anaemia in birds and play a vector role for several human and animal diseases. Five poultry farm buildings of Vikarabad area of Rangareddy district were visited. Samples were collected from a variety of sites, including beneath feed troughs, inside cage fittings and fastening clips, under egg conveyer belts and under manure belts. Heavily mite infested feathers were plucked from three to five individual birds and kept in closed plastic covers. Samples were processed and mounted permanently by using DPX and species differentiation was done. Besides this litter materials and soil samples from the farm were also collected. Massive mixed infestations of Dermanyssus and Ornithonyssus mites were found. The morphological characters provided here can be considered as a practical tool for species differentiation and as these blood feeder mites were most prevalent and important pests of poultry, public health aspects of these parasites should be considered.

Material for study -Right and Left adrenal . No. of Suicidal cases -HundredNo. of Accidental cases (control)-Twenty . Results: On Histological study it was found that the cells in Zona Glomerulosa showed increased nuclear density. Hypertrophy and hyperplasia of Zona Fasciculata with intracytoplasmic lipid depletion varying from mild to extensive giving rise to parenchymal cord-like arrangement of cells .Sinusoidal prominence in all the three zones including medulla.A normal pattern of Adrenal gland is informative of receipt of sudden violence i.e accident. Conclusion: The present study concludes and supports the idea that chronic stress as in suicide usuallyinduces adrenal growth which may have implications for forensic people in revealing the cause of unknown deaths.

The nematodes Dispharynx spiralis (Superfamily-Spiruroidea, Family-Acuariidae) parasitising the proventriculus and Heterakis gallinarum (SuperfamilySubuluroidea, Family-Heterakidae) found in the caecum of two backyard poultry birds are described. The usual location of D. spiralis is glandular stomach or proventriculus, where their heads may be deeply buried in the proventricular wall. H. gallinarum occurs in the caecum and commonly called as caecal worm of poultry.
