...so increase the risks of vector-borne diseases, and the mosquito-borne Dengue virus is one of the pathogens benefitting from this. The related virus Japanese encephalitis virus is the most important cause of mosquito-borne encephalitis in the world, and is maintained in avian reservoirs and amplified by pigs. The occasional spill-over of the virus into humans results in more than 60 000 clinical cases of Japanese encephalitis annually, with high case fatality ...

Two independent studies among febrile patients revealed dengue IgG seroprevalence of 73% and malaria prevalence of 80% in some areas of the country. The diagnosis of the disease is further complicated by the fact that, dengue fever mimics malaria fever and the prevalence of dengue-malaria co-infection is ...

...ntracellular rickettsial vector-borne pathogens that impact on livestock farmers with major economic constraints and eventually threaten human health in cases of zoonotic species involvement. Therefore, our study aimed to identify Anaplasma spp. infection in a bovine host using both microscopy and molecular techniques. A total of 59 samples were collected from Mingaladon township, Yangon region, and the presence of infection was assessed using a Giemsa-stained...

...ologies along with viral vector-based vaccines containing specific DNA segment(s) of an infectious pathogen(s), nanoparticle-based and plant-based delivery mechanisms have proven as more targeted and adaptable approaches to boost immune responses. Hence, it proves the vaccines as a big breakthrough in preventive and therapeutic medicine over 200 years and named “Future Medicine”. To assess vaccine safety and efficacy, scientists are now using vario...

Furthermore, a computational approach was used to understand evolutionary relationships among Cry1AB gene and to identify conserved protein domains in Cry1AB proteins. Use of insilico approach provided new insights of understanding functional characteristics of Cry1AB gene and its variants....

...f animals which serve as vector of different types of pathogens like viruses, bacteria, rickettsia and protozoa and cause mortality in humans and animals. This study was focused on morphological and molecular identification of ixodid ticks, using morphological keys and an internal transcribed spacer (ITS-2) Deoxyribonucleic acid (DNA). Moreover, the presence of Babesia and Theileria species was also investigated in ticks using 18S rRNA gene. Identification of ...

...current study presents a vector/host combination (pET28a(+)/IL-2) and optimization of expression in LB,TB and M9 media with varying concentrations of inducers (IPTG and lactose) and post induction time. Maximum expression of IL-2 was achieved in LB with 0.5 mM IPTG for 6 hours post induction time. A denaturing purification scheme (Immobilized metal affinity chromatography) was employed for the purification of IL-2. The refolding of the purified IL-2 was achiev...

In this study, microhabitats were specified, surveys were conducted to explore specified microhabitats in Chakwal district of Pothwar region, Punjab, Pakistan. After qualitative and quantitative sorting, checklist of mosquitoes along with diversity indices and quantitative habitat web were prepared, which point out the hotspots of different mosquito species. In this study, a total of 580 specimens, comprisin...

The disease mainly exist in cutaneous form while sporadic cases of visceral leishmaniasis has also been reported from the affected areas. Present study was designed to know the species composition, relative abundance and seasonal variation of leishmaniasis vector in an emerging endemic focus of Nowshera. Sand flies collected by flit met...

...eshawar > Charsadda. The vector map for road network and major settlements of the basin showed that Peshawar was the most interlinked district than the other four ones. Image processing for drainage network depicted 8 large and small rivers / streams draining out eventually in to the Indus river. All the rivers/ streams were run through Charsadda and Mardan districts except the Shah Alam in the northern part of Peshawar district.

A total of 150 one-day-old, unsexed broiler chicks were divided into five treatment groups, each further subdivided into three replicates of 10 chicks with an initial average weight of 39 grams. Group A served as the negative control with a non-enzyme supplemented diet, while Group E was the positive control, receiving a diet supplemented with 500 IU of commercial neutral cellulase. Groups B, C, and D...
