Environmental and socio-demographic factors associated with cutaneous leishmaniasis in district Khyber, Pakistan; alarming spread of the disease to new foci.

Cutaneous leishmaniasis (CL) is a sand fly-borne infection of significant public health concern in Pakistan (endemic for CL). This study aimed to scrutinize the environmental and socio-economic risk factors for CL in district Khyber (located on Pak-Afghan border), Pakistan. Clinically confirmed 2881 CL case records for (January-December) 2017 and 2020 were obtained from district hospital.

Insecticide susceptibility and detection of kdr-gene mutations in Aedes aegypti of Peshawar, Pakistan.

Dengue is an endemic disease in Peshawar, Pakistan and its primary vector is Aedes aegypti mosquito. Due to absence of vaccines and proper treatment for dengue, vector control becomes a necessary tool for disease management. Reported insecticide resistance in vectors is a serious threat to the control of dengue.

Characterization of sand fly breeding sites in district Malakand, Khyber Pakhtunkhwa, Pakistan, and evaluation of risk factors for cutaneous leishmaniasis in the region.

Present study was carried to determine the sand fly species composition, breeding sites ecology, seasonal abundance, and spatial distribution in district Malakand, Khyber Pakhtunkhwa, Pakistan. In addition, risk factors associated with cutaneous leishmaniasis (CL) were also evaluated. Survey of indoor and outdoor habitats was carried out using sticky traps in 31 villages of Dargai and Batkhela tehsils of Malakand.

Genotoxic Consequences in Common Grass Carp (Ctenopharyngodon idella Valenciennes, 1844) Exposed to Selected Toxic Metals.

The primary aim of the current study was to recognize the biomarker approach as the finest tool to identify the geno-toxicological effects of copper, chromium, and lead inside the blood of grass carp using micronucleus test and comet assay. The induced micronuclei frequency in response to the administered concentrations of LC50 metals was discovered in the erythrocytes of metal-exposed fish at four-time intervals. The genotoxic effect of these metals with respect to the formation of micronuclei was ranked as chromium > lead > copper.

Sand Fly (Diptera: Psychodidae) Species Diversity, Habitat Preferences, and Ecological Aspects of Distribution in Bajaur District, Khyber Pakhtunkhwa, Pakistan.

The species composition, distribution, and bionomics of sand flies was investigated from January to December 2017 in four tehsils (20 villages) of district Bajaur (formally Bajaur agency), Khyber Pakhtunkhwa, Pakistan. In total, 4,173 adult specimens comprising of seven species of Phlebotomus (Diptera: Psychodidae) and three species of Sergentomyia (Diptera: Psychodidae) were collected by oral aspirator, insecticide spray, and sticky traps from June to October. Highest numbers of flies were collected indoors in July and August when relative humidity and temperature were highest.

Habitat characterization of sand fly vectors of leishmaniasis in Khyber Pakhtunkhwa, Pakistan.

Leishmaniasis is currently prevalent in 98 countries including Pakistan, where its wide-spread. Phlebotomus papatasi Scopoli and Phlebotomus sergenti Parrot are suspected vectors of cutaneous leishmaniasis (CL) while P. Phlebotomus major Yakimoff and Phlebotomus hindustanicus Theodor are vectors of visceral leishmaniasis (VL) in the Khyber Pakhtunkhwa (KP) province of Pakistan.

Malaria epidemiology and comparative reliability of diagnostic tools in Bannu; an endemic malaria focus in south of Khyber Pakhtunkhwa, Pakistan.

The present study was aimed at elucidation of malaria epidemiology and comparing performance of several diagnostic procedures in Bannu, a highly endemic district of Khyber Pakhtunkhwa, Pakistan. Dried blood spots were collected from patients suspected of malaria visiting a hospital and two private laboratories in district Bannu and processed for species-specific PCR (rRNA). Patients were also screened for malaria through microscopy and RDT.

Geospatial and Climatic Patterns Associated With the Distribution of Sand Fly (Diptera: Psychodidae) Vectors of Leishmaniasis in Pakistan.

We provide a comprehensive and updated review on the effects of elevation and climatic factors on distribution of sand fly (Diptera: Psychodidae) vectors of cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) across Pakistan. Our study was undertaken in view of the increasing risk of leishmaniasis, particularly resulting from climatic deviations and political instability in the region. Literature (published and unpublished) on suspected vectors of CL (Phlebotomus sergenti Parrot and Phlebotomus papatasi Scopoli) and VL (Phlebotomus major Yakimoff and Schokhor and Phlebotomus hindustanicus Theodor) was collected, sorted, and utilized in geospatial analysis.

Variability of Cutaneous Leishmaniasis Lesions Is Not Associated with Genetic Diversity of in Khyber Pakhtunkhwa Province of Pakistan.

is the causative agent of cutaneous leishmaniasis in Pakistan. Here, intraspecific diversity of from northern Pakistan was investigated using multilocus microsatellite typing. Fourteen polymorphic microsatellite markers were typed in 34 recently collected isolates from Pakistan along with 158 archival strains of diverse Afro-Eurasian origins.

Potential Resting and Breeding Sites of Sand Flies (Diptera: Psychodidae) and Their Habitat Characteristics in Leishmaniasis Foci of Dir Districts, Khyber Pakhtunkhwa, Pakistan.

Despite their medical importance, natural breeding sites of sand flies have been poorly explored. Detecting such sites is imperative in vector control strategies. This study aimed to identify potential breeding and resting microhabitats of sand flies and household risk factors associated with cutaneous leishmaniasis transmission in Dir districts, Khyber Pakhtunkhwa, Pakistan.

Cutaneous Leishmaniasis in Khyber Pakhtunkhwa Province of Pakistan: Clinical Diversity and Species-Level Diagnosis.

This study primarily aimed to identify the causative species of cutaneous leishmaniasis (CL) in the Khyber Pakhtunkhwa Province of Pakistan and to distinguish any species-specific variation in clinical manifestation of CL. Diagnostic performance of different techniques for identifying CL was assessed. Isolates of Leishmania spp.

Phylogenetic position of Leishmania isolates from Khyber Pakhtunkhwa province of Pakistan.
