Abstract
In human diet, poultry meat is an important component due to the presence of vitamins, proteins and minerals. But poultry meat can be contaminated by pathogenic bacteria which are responsible for food borne infections. The current study was therefore aimed at identification of Escherichia coli, a common pathogen causing food borne infections, in chicken samples (n = 400) collected from three districts of KhyberPukhtunkhwa; Peshawar, Kohat and Nowshera. The isolates were identified by Gram staining, API strips and through PCR (Universal Stress Protein). A total of 174 samples were positive for E. coli among the collected chicken samples. The isolates were resistant to TE, NOR and NA while were sensitive to MEM, TZP and FOS. The results were statistically significant having value P ≤ 0.05 in ANOVA. The isolates showed different antibiotic resistance genes; OXA-1, CTX-M15, blaTEM, QnrS, TetA, AAC, AAD, sul1 and sul2 which is the molecular explanations of their antibiotic resistance pattern. The PCR products were sequenced by Next Generation Sequencing (NGS) and the results revealed mutations in AAC gene (M120T and R197T) and CTX-M15 (A85V, N122D, A148S and G247D). To prevent and treat pathogenic diseases, the use of antimicrobial agents in animal husbandry are of utmost concern. The over-use and misuse of antimicrobial agents has made pathogenic E. coli multi drugs resistant making it a causative agent for many diseases in human beings. The results of the current study may be helpful for the physicians the better management of the diseases caused by E. coli.

Abstract
Blood and fecal samples of chukar partridge (Alectoris chukar), albino pheasant (Phasianus colchicus), silver pheasant (Lophura nycthemera), rose-ringed parakeet (Psittacula krameri) and turkeys (Meleagris gallopavo) were analyzed to check parasitic prevalence. To record parasites these five avian species were placed kept in separate cages at Avian Conservation and Research Center, Department of Wildlife an Ecology, University of Veterinary and Animal Sciences, Lahore, Pakistan. 100 fecal and 100 blood samples for each bird species were inspected to analyze internal parasites. During present study, 17 species of endoparasites 14 from fecal samples and three from blood were examined. Two species of ectoparasites i.e. mite Dermanyssus gallinae 42% and fowl ticks Args persicus 41%were studied. Blood parasites included Plasmodium juxtanucleare 50%, Leucoctoyzoon simond having parasitic prevalence 40%, and Aegyptinella pullorum having parasitic prevalence of 40%. Parasitic species recorded from fecal samples included 6 species of nematodes viz. Allodpa suctoria 2%. Syngamus trachea with parasitic prevalence of 60%, Capillaria annulata 37.5%, Ascardia galli 24%, Capillaria anatis 40% and Heterakis gallinarum 28.3%. Similarly, two species of trematodes viz. Prosthogonimus ovatus having parasitic prevalence of 50% and Prosthogonimus macrorchis 21% were also documented from fecal avian samples . Single cestode species Raillietina echinobothrida having parasitic prevalence of 72% and 3 protozoan species i.e. Eimeria maxima having parasitic prevalence of 21%, Giardia lamblia 41% and Histomonas meleagridis 18% were documented during corpological analysis. In our recommendation, proper sanitation, medication and vaccination of bird's enclousres are suggested to avoid parasites.

Abstract
During the present study, specimens were collected from selected sites of Cholistan desert and Kalabagh Game Reserve, Punjab province, Pakistan. Each captured specimen was tagged with voucher number and morphometric measurements were taken. The average snout to vent length was 172.559±1.40 mm and average weight was 92.1±1.30 g. The DNA of Uromastyx hardwickii was amplified and sequenced using 16S rRNA primer set. The obtained DNA sequence has shown reliable and clear species identification. After trimming ambiguous bases, the obtained 16S rRNA fragment was 520 bp while 16S rRNA fragments aligned with closely matched sequence from NCBI comprised of 510 bp. Closely matched sequences of genus Uromastyx were retrieved from NCBI in blast searches. Neighbour-joining tree of genus Uromastyx was constructed based on p-distance using MEGA X. The mean intraspecific variation was 0.095±0.01 while intraspecific variation was ranging from 0-1%. Similarly, interspecific variation of Uromastyx hardwikii with Saara asmussi, Uromastyx alfredschmidti, Uromastyx geyri, Uromastyx thomasi, Uromastyx alfredschmidti was 0-12%, 0-19%, 0-19%, 0-20%, 12-19% respectively. The newly produced DNA was submitted to NCBI and accession number was obtained (MW052563.1). Results of current study provided information about the molecular and morphological identification of Genus Uromastyx. In our recommendation, comprehensive molecular based identification of Pakistan's reptiles is required to report any new or subspecies from country.

Abstract
Present study was planned to determine variations in external and internal quality egg parameters of different avian species including ostrich Struthio camelus, ducks Anas platyrhynchos, chicken Gallus gallus, turkeys Meleagris gallopavo and grey francolin Francolinus pondicerinus. All the birds were kept under similar rearing conditions. A total of 150 eggs were collected for each species to record external features of these eggs. Statistically significant (p<0.05) variations were recorded in egg weight, egg length and egg width between ostrich, ducks, chicken, turkey and quail eggs. Significantly (p<0.05) higher egg weight, egg length and egg width was observed for ostrich eggs while the same was lowest for grey francolin eggs. Similarly, significantly (p<0.05) greater shape index and egg volume values were observed for ostrich eggs while lowest shape index values were recorded for turkey eggs and egg volume was lowest for grey francolin. Significantly, higher (p<0.05) values of egg density were noted for eggs of the quail and the same were lowest for ostrich eggs. Non-significant variations in egg density values were observed between eggs of the ducks, chicken, turkey and grey francolin. It has been concluded that the positive correlations between the internal and external egg quality traits indicated that the traits can be improved through selection.

Abstract
Crz1p regulates Calcineurin, a serine-threonine-specific protein phosphatase, in Rhizoctonia solani. It has attracted consideration as a novel target of antifungal therapy based on studies in numerous pathogenic fungi, including, Cryptococcus neoformans, Candida albicans and Aspergillus fumigatus. To investigate whether Calcineurin can be a useful target for the treatment of Crz1 protein in R. solani causing wet root rot in Chickpea. The work presented here reports the in-silico studies of Crz1 protein against natural compounds. This study Comprises of quantitative structure-toxicity relationship (QSTR) and quantitative structure-activity relationship (QSAR). All compounds showed high binding energy for Crz1 protein through molecular docking. Further, a pharmacokinetic study revealed that these compounds had minimal side effects. Biological activity spectrum prediction of these compounds showed potential antifungal properties by showing significant interaction with Crz1. Hence, these compounds can be used for the prevention and treatment of wet root rot in Chickpea.

Abstract
Plants have long been used as herbal medicines in many countries. However, microbial contamination of these medicines may affect human health. Present study was performed to assess the pathogenic proliferation in the locally available commercial herbal oral medicines. The pathogenic load was compared with the microbiological standard given by the British Pharmacopoeia. Out of 85 oral liquid samples, 2 were found to be highly contaminated with a total aerobic bacterial load of 1.24 x 10(5) cfu/ml, 10 samples were contaminated with fungi (1.2 x 10(4)-6.3 x 10(4) cfu/ml). Tests for specific pathogens were carried out. One sample showed contamination by coliforms but none of the samples were contaminated by Salmonella spp. and Shigella spp. Among 40 semisolid samples, one showed to be contaminated with bacteria (1.93 x 10(5) cfu/g) and 5 samples consisted of fungal load ranging between 1.5 x 10(4)-2.2 x 10(4) cfu/g. The presence of bacteria and fungi in these samples thus suggest the fact that aseptic handling is necessary during processing of oral herbal medicines.

Abstract
Several studies have shown the role of thiol-rich proteins especially metallothionein (MT) in the therapeutic interventions against oxidative damage. Previously, we have provided strong evidence for the involvement of ROS in iron nitrilotriacetate (Fe-NTA)-induced renal toxicity, which may have relevance to its carcinogenicity. The purpose of this study was to evaluate the role of zinc metallothionein (Zn-MT) on the protection against Fe-NTA-induced renal oxidative damage. The results demonstrate that Zn-MT pretreatment provided protection against Fe-NTA-induced mortality in mice (40% protection). Similarly, Zn-MT pretreatment also provided protection against Fe-NTA-induced lipid peroxidation (26% inhibition, P < 0.001). It is proposed that Zn-MT protects kidney tissue against the noxious effect of Fe-NTA primarily by interference with lipid peroxides. It is concluded that Zn-MT may serve as an excellent physiological antioxidant against Fe-NTA-mediated renal oxidative damage.

Almost 3 to 10% of the oxygen utilized by tissues is converted to its reactive intermediates, which impair the functioning of cells and tissues. Superoxide dismutase (SOD) catalyzes the conversion of single electron reduced species of molecular oxygen to hydrogen peroxide and oxygen. There are several classes of SOD that differ in their metal binding ability, distribution in different cell compartments, and sensitivity to various reagents. Among these, Cu, Zn superoxide dismutase (SOD1) is widely distributed and comprises 90% of the total SOD. This ubiquitous enzyme, which requires Cu and Zn for its activity, has great physiological significance and therapeutic potential. The present review describes the role of SODs, especially Cu, Zn SOD, in several diseases, such as familial amyotrophic lateral sclerosis (FALS), Parkinson's disease, Alzheimer's disease, dengue fever, cancer, Down's syndrome, cataract, and several neurological disorders. Mutations in the SOD1 gene cause a familial form of amyotrophic lateral sclerosis. The mechanism by which mutant SOD1 causes the degeneration of motor neurons is not well understood. Transgenic mice expressing multiple copies of FALS-mutant SOD1s develop an ALS-like motor neuron disease. Vacuolar degeneration of mitochondria has been identified as the main pathological feature associated with motor neuron death and paralysis in several lines of FALS-SOD1 mice. Various observations and conclusions linking mutant SOD1 and FALS are discussed in this review in detail.

Abstract
Free radicals have been suggested to be widely implicated as the species responsible for harmful biological processes, such as aging, carcinogenesis and numerous other diseases. The mechanism of biological damage produced in such processes has been investigated in a wide variety of systems, including studies on proteins, enzymes, nucleic acids and carbohydrates. In the present study we selected an ascorbic acid-transition-metal ion (ASA-Cu(2+)) system in order to understand the mechanism of soluble and membrane-bound enzyme inactivation by generating free radicals. Papain, a thiol protease, was immobilized on an immobilized-metal-ion carrier and used as a model to examine the inactivation behaviour of membrane-bound enzymes. A comparison was made between the inactivation of soluble and immobilized papain by free radicals, and the potential of different radical scavengers to prevent the inactivation of enzyme was examined.
