Hello everybody my name is Zohir Chowdhury, and today we'll talk about vector-borne and zoonotic
diseases affecting humans so zoonotic diseases that affecting humans are being shown in this
table and in this table you can see some of the most important genetic diseases the host or the
reservoirs that harbours the pathogen as well as the pathogen type listed in here the animal
host or reservoir has been further divided into domestic animals and wild animals and
whenever the axis president is table it indicates that that type of animal is not currently the
predominant host or reservoir in this diagram you can visually view the host reservoir information
presented in the previous table in a more visual manner some of the zoonotic diseases spread by
wildlife are Lyme disease hantavirus Ebola and SARS disease spread by livestock's on the other
hand are cow pox Rift Valley fever ecoli and mad cow disease and then there's this other
diseases of animal origins there are rabies and tracts plague avian flu as well as TV in here
we can see a quite a few vector borne diseases that are affecting humans you can see malaria
dengue yellow fever Zika virus chikungunya Japan Japanese encephalitis and st. Louis encephalitis
as well as West Nile all of the diseases the main vector is mosquito including Fleury acids
the vector is also mosquito here the vector has been divided into has been grouped into the three
different types of mosquitoes that call there are predominant vectors of human diseases one
is the aegis Egypt Ike ulis mosquito and then the Anopheles over here so for malaria Zano fields for
dengue yellow and Zeke zika chikungunya Zetas and then for Japanese encephalitis and loose
encephalitis as well as West Nile is the Culex filariasis which is a warm disease can be spread
by all of these three types of mosquitoes plague Lyme disease and leishmaniasis they don't have a
mosquito vectors but they have another vector and for plague is a flea for Lyme disease is a black
legged tick and for leishmaniasis is sand fly the primary host or reservoir as you can see in
some cases is humans in other cases is human in primates and in some cases is Birds or rodents
pathogen has been listed in here in many cases it's a virus or bacteria the dominant pathogen
but in some cases you may have a parasite is a case for malaria and for leishmaniasis is
protozoa and for filariasis is round world since mosquito are so dominant in spreading diseases to
humans in here you can see some of the major diseases that are mosquito-borne so Western
valor Western virus malaria filariasis dengue fever Zika virus yellow fever chikungunya and
Japan Japanese Japanese encephalitis these are some of the major mosquito-borne diseases that
were also presented in the previous table go ahead continue on trying to understand more of
the mosquitoes so we introduced three different mosquitoes the Anopheles the qlex and the eaters
and this species has been extremely successful successful the female because it needs a blood
meal for producing eggs it needs a protein from the blood and at that time the female becomes
extremely aggressive and it seeks human blood that contains that consumes a lot of protein whereas
the meal of the same species they are typically I get there their nutrition from flowers and
nectars whereas the female during your production needs a good protein diet and that's why it needs
blood meal so the NF LS is responsible for the malaria qlex as we mentioned earlier West Nile
virus st. Louis encephalitis Japanese Japanese encephalitis and the ETS mosquito is responsible
for dengue chikungunya Zika as well as yellow fever with respect to the time when they feed
the nfl's is mostly a nighttime fever whereas the QX and edx the primary a daytime theatre and it is
being mostly in the day and qlex dusk to dawn so a nighttime theatre so an ELISA tqex an item theater
and Edith is a data and Peter in both cases blood is their preferred meal especially when they when
they need oh and when the female is about to reproduce the ana Phyllis is found in fresh or
saltwater marshes swamps rice fields edges of rivers streams and pools qlx also like stagnant
water with organic which were over with organic material and the EDS on the other hand has been
highly evolved to live where people live so it lets tool a single eggs on side of water-holding
containers such as flower pop apart spare tires and similar things in here we can see the typical
mosquito breeding sites that are natural and in here you can see most guru buildings that there
are man-made and i was pointing earlier here you have a small little pools of water that can
get collected near who are human lives and this becomes breeding ground of mosquito especially
the the mosquito that is the aegis egypt a which has been adapted to live where humans
are so that's just a quick concept check which of the following is not a disease carried by
mosquito plague is not one malaria dengue and West Nile virus all three are mosquito carry diseases
true or false dengue zika chikungunya can be transmitted by the Aedes mosquito true thank you
