Bioaccumulation of Heavy Metals in Water, Sediments, and Tissues and Their Histopathological Effects on Anodonta cygnea (Linea, 1876) in Kabul River, Khyber Pakhtunkhwa, Pakistan

BioMed Research International (2018)

Muhammad Iftikhar Khan Muhammad Khisroon Ajmal Khan Naila Gulfam Muhammad Siraj

The present investigation aimed to assess the concentrations of selected heavy metals in water and sediments and their bioaccumulation in tissues of freshwater mussels and their histopathological effects on the digestive gland, gills, and gonads of Anodonta cygnea . Water, sediments, and freshwater mussel samples were collected at four sites, that is, reference and polluted sites, along the Kabul River, Khyber Pakhtunkhwa. The polluted sites were receiving effluents from the industrial, agricultural, municipal, and domestic sources. The order of metals in the water was Zn>Pb>Ni>Cu>Mn>Fe>Cr>Cd, in sediments the order was Fe>Zn>Cr>Ni>Mn>Pb>Cu>Cd, and in the soft tissues the order was Fe>Zn>Mn>Pb>Cu>Cr>Ni>Cd. Histopathological alterations observed in polluted sites of Kabul River were inflammation, hydropic vacuolation, and lipofuscin pigments (in digestive gland), gill lamellar fusion, dilated hemolymphatic sinus, clumping, and generation of cilia and hemocytic infiltration (in gills), and atresia, necrosis, granulocytoma, hemocytic infiltration, and lipofuscin pigments (in gonads). The histopathological alterations in the organs of Anodonta cygnea can be considered as reliable biomarkers in biomonitoring of heavy metal pollution in aquatic ecosystems.

Sand Fly (Psychodidae: Phlebotominae) Ecology of an Emerging Cutaneous Leishmaniasis Focus in Khyber Pakhtunkhwa with an Updated Species Checklist from Pakistan

Pakistan Journal of Zoology (2023)

Syed Basit Rasheed Farrah Zaidi Samiullah Samiullah Tehmina Jan

Tick and tick-borne pathogens are among the major threats to animal health and production causing huge economic losses in the form of morbidity and mortality throughout the world.Due to the scarcity of epidemiological data and appropriate diagnostic methods, the study was carried out to detect Anaplasma marginale and Theileria annulata from buffaloes of Sheikhupura, Jhang, and Rawalpindi districts by using duplex PCR.A total of 1,152 blood samples of buffaloes were screened for epidemiological investigations.DNA extracted from blood samples was used for the amplification of the msp1β gene and cytochrome b gene by using single and duplex PCR.The prevalence of these pathogens and associated risk factors were observed through the multiple logistic regression method.The overall prevalence of a single infection of A. marginale was found to be 14.26% and for T. annulata it was 15.28%.The mixed infection, through duplex PCR in the buffalo population, was observed as 12.92%.Different associated risk factors were evaluated to assess their association with the prevalence of these pathogens.Generally, the prevalence was significantly higher in female buffaloes (P=0.0001)during summer season (P=0.0001).Sequencing and phylogenetic analysis of A. marginale showed that Sequence Pak-4* was closely similar to sequences CP006847.1 and appeared in the same clade.Sequence Pak-4* was ascended to Pak-3* isolate and descendant to MK792344.1 Pakistani isolate.On the other hand, phylogenetic analysis of T. annulata showed that the Pak-2* sequence appeared to be descendants of Indian isolate MH78945.1.In the future, this study will be helpful for large-scale analysis of multiple species by using duplex and multiplex PCR and also for improving the control of associated tick-borne diseases in endemic regions through vaccine development.

An overview of the taxonomic instability of endangered Golden and Zhobi mahseer in Pakistan

Brazilian Journal of Biology (2021)

Muhammad Yousaf Zaigham Hasan Farrah Zaidi Syed Basit Rasheed

Abstract In South and South East Asia three genera of fish species i.e. Tor, Neolissochilus and Naziritor are commonly known as Mahseer with at least 47 species. Among these 23 belongs to genus Tor, 22 to Neolissochilus and one to Naziritor i.e. Naziritor zhobensis. Recently another species added to genus Naziritor is Naziritor chelynoides in India. Among Tor species Tor putitora (Hamilton) is the most widely distributed Mahseer in Pakistan and other countries of the Indian subcontinent. However, based alone on morphological characters some authors identify the Pakistani counterparts as Tor macrolepis (Heckel), (a species presumed to be found exclusively in the Indus River system) distinct from Tor putitora (a species found in Ganga Brahmaputra River system). In order to resolve this taxonomic ambiguity, present study carried out meristic and morphometric measurements of Mahseer collected from a total of 11 water bodies of Pakistan. Ratios between the morphometric characters were calculated and statistically analyzed using t-test and correlation coefficient. Two species identified as Tor putitora and Naziritor zhobensis were the sole Mahseer inhabitants of Indus system in Pakistan. Tor putitora occurred at all surveyed sites while Nazirtor zhobensis had a distribution range from river Zhob to tributaries of river Gomal the right bank tributaries of River Indus. The study corroborates that there are no unequivocal morphological synapomorphies in any existing populations of both species. The study further demonstrates that head length, a character frequently used in Mahseer taxonomy, is not a good measure for species identification. Finally the present study establishes that Naziritor zhobensis still exists in the water bodies of Pakistan and that golden Mahseer occurring in Indus riverine system of Pakistan is Tor putitora.

Age and developmental stage specific Bioaccumulation of Copper during acute toxicity of Copper sulphate of two freshwater Fishes Rohu (Labeo rohita) and Mrigal (Cirrhinus mrigala)

Research Square (Research Square) (2023)

Azam Jan Afridi Amina Zuberi Ali Muhammad Yousafzai Farrah Zaidi

Abstract The widespread use of Copper resulted in chronic toxicity, triggering adverse health consequences for the aquatic organism. To investigate bioaccumulation of Copper, acute toxicity test / Median lethal concentration (LC 50 / 96h)) of copper sulphate was performed at four aged group, and developmental stages viz fertilized egg to larvae, swim-up fry, advance fry, and fingerling of two freshwater fishes Rohu ( Labeo rohita ) and Mrigal ( Cirrhinus mrigala ). Each group was exposed to water born copper toxicity in selected glass aquaria. Resulted values of Median lethal concentrations (LC 50 /96h) of copper sulphate at Embryonic and larval, Swim-up fry, Advance fry, and Fingerling stages for Labeo rohita were 0.37, 0.75, 1.07, and 1.34 ppm and for Cirrhinus mrigala were 0.48, 0.94, 1.36, and 1.52 ppm respectively. Copper was analyzed in the whole bodies of first three developmental stages Viz; Embryonic and larval, Swim-up fry, Advance fry, while at fourth i-e at Fingerling stage five tissues Viz; gills, liver, kidney, skin, and muscle were selected. The resulted bioaccumulation order of copper at four developmental stages were Fingerling > Advance fry > Swim-up fry > Embryonic and larval stages for both species. At fourth, fingerling stage bioaccumulation of Copper was resulted in order of gills > liver > skin > kidney > muscle tissues for Rohu, and in order of liver > gills > kidney > skin > muscle tissues of Mrigal. This study provides baseline information for toleration of maximum quantity of Copper at four developmental stages. We recommend the pretreatment of industrial effluent before discharges into freshwater bodies.

An Exploratory Case study of the effect of Ecology on Malaria Risk Factors in Northern Pakistan.

Research Square (Research Square) (2020)

Qaisar Jamal Syed Basit Rasheed Nazma Habib Khan Farrah Zaidi NAZIA NAZ

Abstract Background : Ecology of an area can greatly affects the population of the vector mosquito species by providing conditions for their breeding, thus affecting the transmission of malaria in an area. Areas having similar climate, but dissimilar ecological conditions may alter the factors of malaria transmission, thus resulting in different control strategies for disease management. Current study implies a cross-sectional approach to investigate different malaria risk factors in two ecologically distinct districts of Khyber Pakhtunkhwa, Pakistan. Methods: Data was collected by using closed-ended questionnaire from 2854 and 1944 randomly selected individuals of District Charsadda and Swabi respectively from December to August. A univariate logistic regression analysis was used to measure the association between history of malaria infection and different possible risk factors. Results: 37.6% of the respondents in Charsadda and 46.5% in Swabi were having history of malaria infection. Plasmodium vivax was found to be the dominant species causing infection in the local population. In district Swabi, factors like windows mesh, drinking water source, irrigated fields, sleeping habits, gender and marital status was found significant ( P <0.05) in the transmission of the infection. In district Charsadda, parameters like windows mesh, house made, animals in home, irrigated fields, use of residual sprays, use of repellents, use of bed nets, outdoor night roaming, family history, previous infection and sleeping habits showed significant ( P <0.05) relation to malaria infection. Conclusions: This study provides some basic guidelines by identifying the potential risk factors in districts having diverse ecology to design a comprehensive and effective control strategy to reduce malaria disease burden.

Environmental risk modelling and potential sand fly vectors of cutaneous leishmaniasis in Chitral district: a leishmanial focal point of mount Tirich Mir, Pakistan

Tropical Medicine & International Health (2017)

Farrah Zaidi Syeda Hira Fatima Tehmina Jan Fatima Mehreen Asad Ali

To provide baseline information about suspected vectors and the incidence, distribution and an active zone of transmission for cutaneous leishmaniasis (CL) in Chitral, Pakistan, using GIS tools; and to investigate the role of environmental factors in the disease dynamics.Two surveys in 2014 and 2016 as a basis for choropleth and environmental risk mapping.A total of 769 captured specimens yielded 14 Phlebotomus and six Sergentomyia species including two potential vectors of CL, i.e. Phlebotomus papatasi and Phlebotomus sergenti. P. papatasi (71%) was dominant, followed by P. sergenti (18%). A choropleth map generated in Arcmap 10.1 based on 1560 CL case reports displayed maximum prevalence (0.92-2.5%) in Ayun, Broz, Charun, Chitral 1 and 2 and Darosh 1 and 2 union councils. An environmental risk map constructed by MaxEnt 3.3.3 defined an active zone of transmission based on leishmaniasis occurrence records (n = 315). The analysis of variable contribution in MaxEnt indicates significance of elevation (54.4%), population density (23.3%) and land use/land cover (6.6%) in CL disease dynamics.The probability of CL increases (0.6-1 on logistic scale) in severely deforested areas, in lowland valleys and in regions with high-population density.
