A Call to Introduce Structured Zika Surveillance in India
India has the climatic conditions conducive to year-round transmission of Zika virus, and a structured disease surveillance program should be implemented to prevent an outbreak. Read more on this in Trends in Parasitology
Seasonal dynamics in mosquito abundance and temperature do not influence avian malaria prevalence in the Himalayan foothills
This is the first study from the tropics published in the journal of Ecology and Evolution, which captures the absence of a seasonal pattern in prevalence of avian Plasmodium, despite a strong correlation between mosquito abundance and temperature. These findings are in stark contrast to other studies conducted in temperate regions...read more
Estimating prevalence of avian haemosporidians in natural populations-a comparative study on screening protocols
What’s the best method to estimate avian haemosporidian prevalence in natural populations study published in the journal of Parasites and Vectors compares four commonly used diagnostic protocols and compare them across two labs in India and Sweden. The study highlights the importance of accounting for methodological issues to better estimate infection in parasitological studies and illustrates how a wider deployment of diagnostic tools combined with statistical approaches is needed for each study, in order to provide adequate insight into the most appropriate approach to avoid erroneous inferences.
Exploring host and geographical shifts in transmission of haemospordians in a Palaearctic passerine wintering in India
Study on host and geographical shifts in parasite transmission published in the Journal of Ornithology explores avian malaria parasites of a Palaearctic passerine Blyth’s reed warbler (Acrocephalus dumetorum) that breeds in Europe but winters exclusively in Indian sub-continent. In the Central Asian Flyway, India is a staging and wintering ground for many European passerines; however lacks information on transmission or exchange of parasite through migrant birds. Using combination molecular and morphological techniques, this study confirmed that not all migrant species are involved in host and geographical shifts in transmission of vector-mediated parasites which require a definite host (e.g. insect vector) for successful transmission.
Life-history characteristics influence physiological strategies to cope with hypoxia in Himalayan birds
Hypoxia study in Himalayan birds published in Proceeding of the Royal Society B highlights how birds at high altitude meet their oxygen demand. With climate change, many bird species are likely to move upwards in response to rise in temperature, however hypoxia can be a major hurdle in coping with this shift in their ranges.
