    STUDY ON CERTAIN ASPECTS OF VECTOR CAPACITY OF CULICOIDES SPECIES IN RELATION TO BLUETONGUE
    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2006) SATHEESHA, S- P.
    Culicoides flies are tiny insects commonly known as â biting midgesâ ?. These midges are the most abundant and smallest haematophagous insects occurring throughout most of the inhabited world. They are the pests of veterinary and medical importance and inflict painful bites. In addition to feeding on blood of domestic animals and man, they cause annoyance and allergic reactions. However, their importance lies in the transmission of a greater number of assorted pathogens of human, domestic and wild animals. But it is as vectors of arboviruses, particularly arboviruses of domestic livestock, that they achieve their prime importance. To date, over 50 viruses have been isolated from Culicoides species. Among these, bluetongue virus (BTV) causes disease of such international significance that it has been allocated OlE list A status. The resultant consequence is the trade barrier on movement of ruminants, their germplasms and other animal products, thus, disrupting the international commerce (Mellor, 1996).

    EPIDEMIOLOGICAI. ASPECTS OF HAEMORRHAGIC SEPTICAEMIA IN KARNATAKA STATE
    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2006) RAJASHEKHAR D. PATIL
    Haemorrhagic septicaemia (HS) is caused by Pasteurella multocida (Past, multocida) type 1 or B and occurs in domestic animals especially in cattle and buffaloes (Khera, 1979). It appears that HS has been recorded on clinical and bacteriological grounds in 70 countries and is suspected to occur but not confirmed in about 20 countries (De Alwis, 1984). HS has been recorded in many parts of India. Among top five important diseases of our country, HS occupies second and first positions in morbidity and mortality respectively (Dutta et al., 1990). It has been recorded in many states of India almost every year affecting and killing large number of animals, thus causing severe economic loss.

    EPIDEMIOLOGICAL, BIOCHEMICAL AND ANTIBIOGRAM STUDY OF BLACK QUARTER IN KARNATAKA STATE
    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2005) VIJAYKUMAR N. TELAGAR
    Black quarter (BQ) is an important infectious bacterial disease causing wide spread damage among the livestock especially cattle, buffaloes and sheep. It is also reported in a variety of animals, including fish and whales, but is of utmost importance in cattle and sheep. Pigs are very rarely affected; man and equidae are completely resistant (Sterne, 1975). True Black quarter (BQ) is caused by Clostridium chauvoei (Cl. chauvoei) sometimes referred to as Cl. feseri (Batta et al., 1995), but mixed infections resulting from Cl. chauvoei and Cl. septicum are not uncommon, albeit, the significance of Cl. septicum is still debated (Barnes et al., 1975).

    EPIDEMIOLOGICAL ASPECTS OF FOOT AND MOUTH DISEASE IN CATTLE AND BUFFALOES OF KARNATAKA STATE
    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2005) VENKATESH, S. H.
    Foot and mouth disease (FMD) is an acute infectious disease of cattle, swine, sheep, goats and other cloven footed animals (Fincher et al, 2001). It is caused by an apthovirus of family picornaviridae, which occurs as seven major serotypes viz, O, A, C, South African Territories (SAT) 1, 2, 3 and Asia 1 (Radostits et al., 2003). FMD is one of the most important animal diseases in the world and in India the disease is endemic (Sharma, 1998). Previously it was considered as the second most serious animal disease in India after rinderpest (RP) (Saxena, 1995) but now it has occupied the first place as RP is not recorded. Ellis and James (1976) estimated the economic losses due to FMD in bovine population of India as Rs. 420 crores per year. However, the National Dairy Development Board (NDDB) has updated the estimate as Rs. 1,000 crores (Saxena,1995).
