Introduction Kyasanur Forest Disease (KFD), also referred to as monkey fever is an infectious bleeding disease in monkey and human caused by a highly pathogenic virus called KFD virus. It is an acute prostrating febrile illness, transmitted by infective ticks, especially, Haemaphysalis spinigera. Later KFD viruses also reported from sixteen other species of ticks. Rodents, Shrews, Monkeys and birds upon tick bite become reservoir for this virus. This disease was first reported from the Shimoga district of Karnataka, India in March 1955. Common targets of the virus among monkeys are langur (Semnopithecus entellus) and bonnet monkey (Macaca radiata). -

Virulence During Newcastle Disease Viruses Cross Species Adaptation
viruses Review Virulence during Newcastle Disease Viruses Cross Species Adaptation Claudio L. Afonso Base2bio, LLC, Oshkosh, WI 54905, USA; [email protected]; Tel.: +1-800-817-7160 Abstract: The hypothesis that host adaptation in virulent Newcastle disease viruses (NDV) has been accompanied by virulence modulation is reviewed here. Historical records, experimental data, and phylogenetic analyses from available GenBank sequences suggest that currently circulating NDVs emerged in the 1920–19400s from low virulence viruses by mutation at the fusion protein cleavage site. These viruses later gave rise to multiple virulent genotypes by modulating virulence in opposite directions. Phylogenetic and pathotyping studies demonstrate that older virulent NDVs further evolved into chicken-adapted genotypes by increasing virulence (velogenic-viscerotropic pathotypes with intracerebral pathogenicity indexes [ICPIs] of 1.6 to 2), or into cormorant-adapted NDVs by moderating virulence (velogenic–neurotropic pathotypes with ICPIs of 1.4 to 1.6), or into pigeon-adapted viruses by further attenuating virulence (mesogenic pathotypes with ICPIs of 0.9 to 1.4). Pathogenesis and transmission experiments on adult chickens demonstrate that chicken-adapted velogenic-viscerotropic viruses are more capable of causing disease than older velogenic-neurotropic viruses. Currently circulating velogenic–viscerotropic viruses are also more capable of replicating and of being transmitted in naïve chickens than viruses from cormorants and pigeons. These evolutionary virulence changes are consistent with theories that predict that virulence may evolve in many directions in order to achieve maximum fitness, as determined by genetic and ecologic constraints. Keywords: NDV; evolution; virulence; host adaptation Citation: Afonso, C.L. Virulence during Newcastle Disease Viruses Cross Species Adaptation. -

Species Composition of Hard Ticks (Acari: Ixodidae) on Domestic Animals and Their Public Health Importance in Tamil Nadu, South India
Acarological Studies Vol 3 (1): 16-21 doi: 10.47121/acarolstud.766636 RESEARCH ARTICLE Species composition of hard ticks (Acari: Ixodidae) on domestic animals and their public health importance in Tamil Nadu, South India Krishnamoorthi RANGANATHAN1 , Govindarajan RENU2 , Elango AYYANAR1 , Rajamannar VEERAMANO- HARAN2 , Philip Samuel PAULRAJ2,3 1 ICMR-Vector Control Research Centre, Puducherry, India 2 ICMR-Vector Control Research Centre Field Station, Madurai, Tamil Nadu, India 3 Corresponding author: [email protected] Received: 8 July 2020 Accepted: 4 November 2020 Available online: 27 January 2021 ABSTRACT: This study was carried out in Madurai district, Tamil Nadu State, South India. Ticks were collected from cows, dogs, goats, cats and fowls. The overall percentage of tick infestation in these domestic animals was 21.90%. The following ticks were identified: Amblyomma integrum, Haemaphysalis bispinosa, Haemaphysalis paraturturis, Haemaphy- salis turturis, Haemaphysalis intermedia, Haemaphysalis spinigera, Hyalomma anatolicum, Hyalomma brevipunctata, Hy- alomma kumari, Rhipicephalus turanicus, Rhipicephalus haemaphysaloides and Rhipicephalus sanguineus. The predomi- nant species recorded from these areas is R. sanguineus (27.03%) followed by both R (B.) microplus (24.12%) and R. (B.) decoloratus (18.82%). The maximum tick infestation rate was recorded in animals from rural areas (25.67%), followed by semi-urban (21.66%) and urban (16.05%) areas. This study proved the predominance of hard ticks as parasites on domestic animals and will help the public health personnel to understand the ground-level situation and to take up nec- essary control measures to prevent tick-borne diseases.
