Soil salinity is the major abiotic stress that disrupts nutrient uptake, hinders plant growth, and threatens agricultural production. Plant growth-promoting rhizobacteria (PGPR) are the most promising eco-friendly beneficial microorganisms that can be used to improve plant responses against biotic and abiotic stresses. In this study, a previously identified B. thuringiensis PM25 showed tolerance to salinity stress up to 3 M NaCl. The Halo-tolerant Bacillus thuringiensis PM25 demonstrated distinct salinity tolerance and enhance plant growth-promoting activities under salinity stress. Antibiotic-resistant Iturin C ( ItuC ) and bio-surfactant-producing ( sfp and srfAA ) genes that confer biotic and abiotic stresses were also amplified in B. thuringiensis PM25. Under salinity stress, the physiological and molecular processes were followed by the over-expression of stress-related genes (APX and SOD) in B. thuringiensis PM25. The results detected that B. thuringiensis PM25 inoculation substantially improved phenotypic traits, chlorophyll content, radical scavenging capability, and relative water content under salinity stress. Under salinity stress, the inoculation of B. thuringiensis PM25 significantly increased antioxidant enzyme levels in inoculated maize as compared to uninoculated plants. In addition, B. thuringiensis PM25-inoculation dramatically increased soluble sugars, proteins, total phenols, and flavonoids in maize as compared to uninoculated plants. The inoculation of B. thuringiensis PM25 significantly reduced oxidative burst in inoculated maize under salinity stress, compared to uninoculated plants. Furthermore, B. thuringiensis PM25-inoculated plants had higher levels of compatible solutes than uninoculated controls. The current results demonstrated that B. thuringiensis PM25 plays an important role in reducing salinity stress by influencing antioxidant defense systems and abiotic stress-related genes. These findings also suggest that multi-stress tolerant B. thuringiensis PM25 could enhance plant growth by mitigating salt stress, which might be used as an innovative tool for enhancing plant yield and productivity.

The aim of the present study was to assess the drinking water quality in the selected urban areas of Lahore and to comprehend the public health status by addressing the basic drinking water quality parameters. Total 50 tap water samples were collected from groundwater in the two selected areas of district Lahore i.e., Gulshan-e-Ravi (site 1) and Samanabad (site 2). Water samples were analyzed in the laboratory to elucidate physico-chemical parameters including pH, turbidity, temperature, total dissolved solids (TDS), electrical conductivity (EC), dissolved oxygen (DO), total hardness, magnesium hardness, and calcium hardness. These physico-chemical parameters were used to examine the Water Quality Index (WQI) and Synthetic Pollution Index (SPI) in order to characterize the water quality. Results of th selected physico-chemical parameters were compared with World Health Organization (WHO) guidelines to determine the quality of drinking water. A GIS-based approach was used for mapping water quality, WQI, and SPI. Results of the present study revealed that the average value of temperature, pH, and DO of both study sites were within the WHO guidelines of 23.5 °C, 7.7, and 6.9 mg/L, respectively. The TDS level of site 1 was 192.56 mg/L (within WHO guidelines) and whereas, in site 2 it was found 612.84 mg/L (higher than WHO guidelines), respectively. Calcium hardness of site 1 and site 2 was observed within the range from 25.04 to 65.732 mg/L but, magnesium hardness values were higher than WHO guidelines. The major reason for poor water quality is old, worn-out water supply pipelines and improper waste disposal in the selected areas. The average WQI was found as 59.66 for site 1 and 77.30 for site 2. Results showed that the quality of the water was classified as “poor” for site 1 and “very poor “ for site 2. There is a need to address the problem of poor water quality and also raise the public awareness about the quality of drinking water and its associated health impacts.

Plant viral diseases are the foremost threat to sustainable agriculture, leading to several billion dollars in losses every year. Many viruses infecting several crops have been described in the literature; however, new infectious viruses are emerging frequently through outbreaks. For the effective treatment and prevention of viral diseases, there is great demand for new techniques that can provide accurate identification on the causative agents. With the advancements in biochemical and molecular biology techniques, several diagnostic methods with improved sensitivity and specificity for the detection of prevalent and/or unknown plant viruses are being continuously developed. Currently, serological and nucleic acid methods are the most widely used for plant viral diagnosis. Nucleic acid-based techniques that amplify target DNA/RNA have been evolved with many variants. However, there is growing interest in developing techniques that can be based in real-time and thus facilitate in-field diagnosis. Next-generation sequencing (NGS)-based innovative methods have shown great potential to detect multiple viruses simultaneously; however, such techniques are in the preliminary stages in plant viral disease diagnostics. This review discusses the recent progress in the use of NGS-based techniques for the detection, diagnosis, and identification of plant viral diseases. New portable devices and technologies that could provide real-time analyses in a relatively short period of time are prime important for in-field diagnostics. Current development and application of such tools and techniques along with their potential limitations in plant virology are likewise discussed in detail.

Moringa oleifera ’s rich phytochemical profile positions it as a promising natural alternative for sustainable pest management. This study characterizes the phytochemical composition and antioxidant activity of M. oleifera extracts and, for the first time, evaluates their insecticidal potential against Tribolium castaneum (red flour beetle). Extracts from leaves, stems, roots, and seeds were prepared using ethanol, methanol, acetone, and distilled water. Phytochemical analysis identified high levels of total phenolics (7.18 µg GAE/mg DW, ethanol leaf extract), flavonoids (23.52 µg QE/mg DW, ethanol leaf extract), tannins (245.4 mg CE/g DW, acetone seed extract), saponins (13.7%, methanol leaf extract), and alkaloids (30.06 mg atropine/100 mL, water stem extract). HPLC quantification revealed abundant bioactive compounds, including phenolic acids (gallic, caffeic, chlorogenic, and ferulic acids), flavonoids (apigenin, quercetin, kaempferol), flavanols (catechin, epicatechin, procyanidin dimers), and iridoids (oleuroside), with gallic acid, quercetin-3-O-rhamnoside, and kaempferol as dominant constituents. Antioxidant assays demonstrated significant activity, with methanol root extract showing 71% DPPH inhibition and methanol stem extract exhibiting the highest total antioxidant capacity (36.12 mg GAE/g DW). Insecticidal bioassays revealed ethanol root extracts induced 90% mortality in T. castaneum within 24 h at 30% concentration, outperforming other extracts. These findings underscore M. oleifera ’s dual functionality as a potent bioinsecticide and antioxidant, advocating for its integration into sustainable pest management. Further research should optimize extraction protocols and field-scale formulations to enhance practical applications.

The purpose of the current work was to develop and characterize ethosomes of vitamin D3 gel that could more effectively work against psoriasis. Psoriasis is a chronic immune-mediated inflammatory skin disease. Due to vitamin D3 role in proliferation and maturation of keratinocytes, it has become an important local therapeutic option in the treatment of psoriasis. In this research we have initiated worked on ethosomes gels containing vitamin D3 to treat psoriasis. Soya lecithin 1–8% (w/v), propylene glycol and ethanol were used to create the formulations, which were then tested for vesicle size, shape, surface morphology, entrapment effectiveness, and in vitro drug permeation. The drug encapsulation efficiency of ethosomes was 96.25% ± 0.3. The particle sizes of the optimized ethosomes was 148 and 657 nm, and the PDI value was 0.770 ± 0.12 along with negative charge − 14 ± 3. Fourier transform infrared (FT-IR) spectroscopy and differential scanning calorimetry (DSC) along with thermogravimetric analysis (TGA) studies confirmed the absence of interactions between vitamin D3 and other ingredients. It was determined that the total amount of medication that penetrated the membrane was 95.34% ± 3. Percentage lysis was very negligible for all strengths which were found less than 15%. Based on our research, ethosomes appear to be safe for use. The vitamin D3 ethosomal gel order, description, pH, and viscosity were all within the specified ranges, according to the findings of a 6-month investigation into the stability profile of the completed system. In this research, we successfully prepared ethosomes loaded with vitamin D3 and then converted it into gel for patients’ easy applications.

Starch is added to the fabric surface to secure weaving process. During finishing these sized particles are removed from the fabric and prepared it for printing and dyeing. Chemicals de-sizing agents damage fabric surfaces and reduce the quality of the product. An alternative to these conventional desizing agents is the use of biological molecules i.e. enzymes. The current study compares traditional de-sizing to bio-based de-sizing methods, as well as the optimization of fabric desizing settings using crude amylase. Amylase-producing Bacillus cereus AS2 was isolated from indigenous soil samples. The maximal fermentative de-sizing capability was discovered at 72 h, with no fabric surface degradation. Chemical desizing showed that the fabric lost all sizing agents to TEGEWA scale 9 within 1 h in presence of 5N HCl. Optimal studies for desizing showed that 1000 IU/ml of amylase resulted in maximum de-sizing within 15 h at 60 °C and 0.5% Triton-X. Water absorbance and weight loss, both parameters were used to check the desizing efficacy and it was found that de-sizing to same scale was occurred in the case of enzyme as well as commercially desized fabric. Enzyme desized cloth was found to be free of any starch particles in SEM micrographs, identical to industrially de-sized fabric, ensuring bioprocess efficacy.

Hatcheries have the power to spread antimicrobial resistant (AMR) pathogens through the poultry value chain because of their central position in the poultry production chain. Currently, no information is available about the presence of AMR Escherichia coli strains and the antibiotic resistance genes (ARGs) they harbor within hatchezries. Therefore, this study aimed to investigate the possible involvement of hatcheries in harboring hemolytic AMR E . coli . Serotyping of the 65 isolated hemolytic E . coli revealed 15 serotypes with the ability to produce moderate biofilms, and shared susceptibility to cephradine and fosfomycin and resistance to spectinomycin. The most common β-lactam resistance gene was bla TEM , followed by bla OXA-1 , bla MOX -like , bla CIT -like , bla SHV and bla FOX . Hierarchical clustering of E . coli isolates based on their phenotypic and genotypic profiles revealed separation of the majority of isolates from hatchlings and the hatchery environments, suggesting that hatchling and environmental isolates may have different origins. The high frequency of β-lactam resistance genes in AMR E . coli from chick hatchlings indicates that hatcheries may be a reservoir of AMR E . coli and can be a major contributor to the increased environmental burden of ARGs posing an eminent threat to poultry and human health.

Developing special textiles (for patients in hospitals for example) properties, special antimicrobial and anticancer, was the main objective of the current work. The developed textiles were produced after dyeing by the novel formula of natural (non-environmental toxic) pigments (melanin amended by microbial-AgNPs). Streptomyces torulosus isolate OSh10 with accession number KX753680.1 was selected as a superior producer for brown natural pigment. By optimization processes, some different pigment colors were observed after growing the tested strain on the 3 media. Dextrose and malt extract enhanced the bacteria to produce a reddish-black color. However, glycerol as the main carbon source and NaNO 3 and asparagine as a nitrogen source were noted as the best for the production of brown pigment. In another case, starch as a polysaccharide was the best carbon for the production of deep green pigment. Peptone and NaNO 3 are the best nitrogen sources for the production of deep green pigment. Microbial-AgNPs were produced by Fusarium oxysporum with a size of 7–21 nm, and the shape was spherical. These nanoparticles were used to produce pigments-nanocomposite to improve their promising properties. The antimicrobial of nanoparticles and textiles dyeing by nanocomposites was recorded against multidrug-resistant pathogens. The new nanocomposite improved pigments' dyeing action and textile properties. The produced textiles had anticancer activity against skin cancer cells with non-cytotoxicity detectable action against normal skin cells. The obtained results indicate to application of these textiles in hospital patients’ clothes.

Honey bees are vital pollinators essential for ecosystems and global agriculture, but their populations are declining due to pressures caused by pests. This study reports the presence of Escherichia coli , Klebsiella pneumoniae , Proteus terrae , and Pseudomonas spp . in four different honey bee species in Pakistan for the first time, uncovering a previously neglected aspect of honey bee microbiology. From January 2023 to June 2024; 1190 honey bees were collected from four districts in Khyber Pakhtunkhwa and they were identified. Molecular screening based on PCR targeting the microbial 16 S rDNA resulted in the detection of potential bacterial pathogens across different districts. In Buner, K. pneumoniae and E. coli were detected in Apis mellifera and Apis cerana individuals while Apis florea was positive only for K. pneumoniae . In Swat, Pseudomonas spp . was identified in A. mellifera , Apis dorsata and A. florea , while in A. cerana no pathogen was detected. In Lower Dir, A. mellifera and A. florea were positive for Pseudomonas spp. , and A. cerana for K. pneumoniae , with A. dorsata being pathogen-free. In Malakand, K. pneumoniae and E. coli was found in A. mellifera and A. cerana , while A. florea harbored only Pseudomonas spp ., and A. dorsata had no pathogens. Finally, P. terrae was detected exclusively in A. mellifera from Buner and Swat. Morphological analysis revealed significant interspecies variation, with A. dorsata exhibiting the largest values in tongue length (4.27 ± 0.21 mm), forewing size (12.8 ± 0.19 mm), and the highest cubital index (2.71 ± 0.04 mm). A. mellifera was classified in second place, followed by A cerana and A . florea, which characterized by the lowest measurement values. In the present study significant bacterial pathogens were identified representing emerging threat to honey bees in Pakistan while data regarding their phenotypic characterization and phylogenetic position were provided for the first time in the region.

Currently, HIV (human immunodeficiency virus) infection is one of the leading complications in public health and causes acquired immunodeficiency syndrome (AIDS), especially in the African region. No specific vaccine is available to combat this, with multi-strain variability being one of the hurdles. In this investigation, we employed variability in the epitope of the HIV subtype C targets to introduce mutations and construct an epitope-based vaccine. Four targets were examined to predict the B and T cells (major histocompatibility complex class I and II). Among the predicted epitopes, immunodominant epitopes were selected and were mapped with the identified variable amino acid to incorporate mutation. These selected and mutated epitopes were used for the non-mutated and mutated vaccine construction, considering linker for fusion and adjuvant to improve the activity. The vaccine’s structure was modeled and examined to validate its structural quality, and a high population coverage was also found. The docking investigation of the non-mutated and mutated vaccine with Toll-like receptor 3 shows remarkable activity followed by strong binding affinity, and the simulation of over 100 ns revealed the constancy of the complex system. The immune response revealed its strong effectiveness by generating multiple immunoglobulins followed by the time step of infection, and further, in silico cloning demonstrated a high expression in Escherichia coli based on their favorable Codon Adaptation Index and GC value. The integrated approach in this investigation will help to plan a potent immunodominant vaccine that can work for multiple strains of HIV infection.
