Abstract
Immunoaffinity chromatography (IAC) is a fundamental isolation and purification tool which is incorporated in a substantial range of therapeutic and diagnostic applications. This study has reappraised the usefulness of immunoaffinity chromatography for the purification of polyclonal antibodies. Protein A based IAC is a convenient and reliable method for purification of IgG, from hyperimmunesera (HIS) raised in experimental animals such as rabbits, guinea pigs and mice to be utilized in pharmaceutics and diagnostics. The 146S fraction of Foot and Mouth Disease virus (FMDV) TCID50=10 5.6 was cultured on a baby hamster kidney cell line 21 (BHK-21), concentrated using salt precipitation method using PEG 6000, purified by size exclusion chromatography (SEC) using Sepharose-30 at 254nm absorbance. Purification of 146S FMDV was analyzed using 12% SDS-PAGE which provided two bands of light and heavy chains. The alum-based vaccine, consisting of ≥10μg of 146S FMDV, was applied in 10 male rabbits and 10 male guinea pigs and two animals of each group were taken as a negative control. The titer of serum was calculated using virus neutralization test. A Protein-A kit (Thermo scientific- 44667, 0528.2) was used to purify HIS raised against 146S FMDV and validated using 12% SDS PAGE in reducing condition. The data demonstrate that protein-A affinity chromatography is an efficient tool for the purification of antibodies from hyper-immune sera raised against 146S FMDV and can be used for the production of diagnostic kits e.g. Enzyme linked immuno-sorbent assay (ELISA) and radioimmunoassay.

Abstract
The present study was conducted to investigate the antimicrobial potential of essential oils of Curcuma longa and Syzygium aromaticum against multidrug-resistant pathogenic bacteria. Four identified bacterial isolates including Methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli, Klebsiella pneumoniae, and Acinetobacter baumannii were selected and their antibiotic sensitivity was checked by disc diffusion assay. C. longa and S. aromaticum were subjected to steam distillation to obtain their essential oils. The crude essential oils were fractioned by employing column chromatography. Crude essential oils and their fractions were evaluated for their antibacterial activity by agar well diffusion assay and minimum inhibitory concentrations were calculated. All the selected bacterial isolates showed resistance to three or more than three antibiotic groups and were declared as multidrugresistant (MDRs). Crude essential oils of C. longa and S. aromaticum exhibited antimicrobial activity against all selected isolates but S. aromaticum activity was better than the C. longa with a maximum 19.3±1.50 mm zone of inhibition against A. baumannii at 1.04 µL/mL MIC. GC/MS analysis revealed the abundance of components including eugenol, eugenyl acetate, b- caryophyllene, and a- Humulene in both crude oil and fractions of S. aromaticum. While the main components of C. longa essential oil were Ar-tumerone, a-tumerone, b- Tumerone, I-Phellandrene, a-zingibirene, b- sesquiphellandrene, and p- Cymene. This study highlights that plant-based essential oils could be a promising alternative to antibiotics for which pathogens have developed resistance. C. longa and S. aromaticum carry compounds that have antimicrobial potential against multiple drug-resistant bacteria including MRSA. E. coli, K. pneumoniae and A. baumannii.

Abstract
The frequency of Staphylococcus aureus strains associated with oral cavity microbiota has prodigious consideration. Although S. aureus has been reflected as an ephemeral member of the human oral cavity microbiota, the isolation, identification, and characterization of S. aureus is important. The present study aimed to characterize S. aureus strains from the oral cavity microflora, isolation of S. aureus from the human oral cavity microbiota, and demographic information of the participants to evaluate exogenous factors associated with the presence of S. aureus and their genetic analysis linkage with different factors. The method used in this study is the isolation of oral cavity microbiomes using sheep blood agar and Mannitol salt agar. We performed antibiotic profiling with various antibiotics and genetic analysis utilizing gene-specific primers for specific genes, including nuc, mecA, pvl, agr, and coa. A significant number of S. aureus isolates were found in the oral cavity of humans 18/84 (21.42%), and all 18 strains tested positive for the confirmatory nuc gene. Antibiotic resistance-conferring gene mecA was positive in 10 (55.6%) isolates. It was found that the occurrence of pvl, agr, and coagulase (coa) genes was 9 (50%), 6 (33.33%), and 10 (55.6%), respectively. The genetic analysis reported that significant associations were present between male and mecA gene (P = 0.03) and coa (P = 0.03), smokers with the occurrence of mecA (P = 0.02), agr (P = 0.048) and coa (P = 0.02) genes. Likewise, the association of antibiotic usage was significantly found with mecA (P = 0.02), coa (P = 0.02); however, the individuals who have taken orthodontic treatment recently have a significant association with agr (P = 0.017). The use of mouth rinse was significantly associated with the prevalence of the pvl gene (P = 0.01), and tooth brushing frequency and inflammation of the buccal cavity were also statistically significant in relation to pvl gene prevalence (P = 0.02, 0.00, respectively). Moreover, calories and weight-controlled diet were significantly associated with mecA, agr, and highly significant with coa (P = 0.02, 0.048, 0.000), so all P < 0.05, and no significant association was found between the socioeconomic status of individuals with aforementioned analyzed genes.

Abstract
Thirty puppies were randomly divided in to 3 groups for comparative evaluation of two commercial CPV vaccines. Each group was further subdivided in to < 6 months and < 3 months -old puppies and either vaccinated with a monovalent vaccine: Primodog, a combination vaccine: Duramune or maintained as a non-vaccinated control. Humoral immune response was determined by Hemagglutination Inhibition (HAI) on 21 and 35 -days after vaccination. The geometric mean titer (GMT) induced by Duramune, 21 and 35 -days post-vaccination was GMT 73.3 and 137.2, respectively. Comparatively, Primodog demonstrated higher GMT on 21 and 35 -days after vaccination: 97.0 and 168.9, respectively. The older puppies (< 6 months old) demonstrated higher seroconversion to both vaccines.

Abstract
Boophilus microplus is a major cattle tick specie causing great economic loss to the dairy industry throughout the globe including Pakistan. Trichlorfon and Deltamethrin are used to control bovine ticks, and their sprays are also used in other pest control programs that exert pressure on ticks to gain resistance. This study is aimed to examine the resistance level of Rhipiciphalus microplus against trichlorfon and deltamethrin. The engorged ticks were collected from two ecological regions of Khyber Pakhtunkhwa, KPK Pakistan i.e., Swat & Dir (zone-1), and Charsadda & Nowshera (zone-2). Four concentrations of acaricides in two-fold and ten-fold ppm with three replicates for each were used in both bioassays. Egg hatch assay and adult immersion tests were used to assess the resistance status. The probit analysis of egg hatch assay showed the highest hatching percentage in zone 1 on both dilutions (67-76% on two-fold and 68-88% on ten-fold dilution) while lethal concentration (LC95) was found to be 2.187 ppm and discriminating dose (DD) as 4.374 ppm for trichlorfon. In zone 2, hatching percentage was 73-84 on two-fold and 72-91% on ten-fold dilution while LC95 was recorded as 0.599 ppm and DD as 1.198 ppm. The same parameters were studied for deltamethrin and in zone 1 the hatching percentage was found as 38-56% on two-fold dilution and 37-80% on ten-fold dilution while LC95 was recorded as 0.001 ppm and DD as 0.002 ppm. In zone 2, the hatchability was recorded as 42-58% on two-fold and 43-85% on ten-fold dilution. The values for LC95 was recorded as 0.001 ppm and DD as 0.002 ppm. Further, analysis of adult immersion test against trichlorfon revealed the values of LC50 as 2.85 ppm and LC95 as 4.71 ppm in zone 1 and in zone 2 as 3.14 ppm and 5.28 ppm, respectively. Similarly, LC50 and LC95 against deltamethrin was recorded as 0.79 ppm & 1.71 ppm in zone 1 and 0.45 ppm & 4.325 ppm in zone 2, respectively. Based on the findings of this study, the isolated Rhipicephalus microplus was found to be more resistant to the widely used acaricides i.e., trichlorfon than deltamethrin. In order to maintain the efficacy of acaricides at country level, the study recommends continuous monitoring of resistance.

Abstract
Lactobacilli are probiotics with Aflatoxin (AF) detoxification ability, found in fermented products, GIT of animals and environment. Purpose of this study was to investigate the ability of broiler isolates of Lactobacillus against Aflatoxin B1 (AFB1). For this purpose, 5 isolates of Lactobacillus from broiler gut were incubated with 100 ppb AFB1 in aqueous environment and effect of different parameters (cell fractions, time, temperature, pH) on detoxification was determined by HPLC. The ameliorative effect of Lactobacillus salivarius (LS) against AFB1 was studied in broiler. The results revealed that LS (CR. 4) showed the best results (in vitro) as compared to other isolates (L. salivarius (CR. 3, CR, 4), L. agilis (CE. 2.1, CE. 3.1) and L. crispatus (CE. 28). Cell debris of CR. 4 showed significantly higher detoxification (P<0.05). Maximum amount of AFB1 was detoxified at 30°C (97%), pH 4.0 (99%) and 6 h (99.97%). In vivo study showed that AFB1 decreased weight gain (1,269 ± 0.04 gm/ bird), feed consumed (2,161 ± 0.08 gm/ bird), serum total protein (2.42 ± 0.34 gm/ dl), serum albumin (0.5 ± 0.2 2 gm/dl) and antibody titer (4.2 ± 0.83). Liver function enzymes were found (alanine transaminase (ALT): 32 ± 10.7 U/L) and aspartate transaminase (AST): 314.8 ± 27 U/L) elevated in AFB1 fed broilers. Treatment with 1% LS not only decreased the toxic effects of AFB1 (group D) but also improved the overall health of broilers due to its probiotic effects (p<0.05) as compared to control negative (group A). The detoxification ability of LS was better than commercial binder (CB) (0.2% Protmyc). It was concluded that detoxification of AFB1 by Lactobacillus was strain, temperature, pH and time dependent. LS has detoxification ability against AFB1 in vivo.

Abstract
Foot-and-mouth disease (FMD) is a highly infectious disease of cattle and other cloven-hoofed animals, causing huge economic losses annually worldwide. This disease is endemic in Pakistan where the serotypes of the foot-and-mouth disease virus (FMDV) are A, O and ASIA-1. At present, trivalent FMDV vaccines are being used to prevent FMD but the current production process is laborious and is unable to fulfill the needs of the meat and dairy industries. To meet the vaccine needs of Pakistan, the conventional method of using adherent cell lines to produce the vaccine could be replaced by suspension cell cultures which produce higher yields in less time and less volume. Therefore, the aim of this study was to investigate and optimize some of the factors that affect viable cell density and subsequent virus yield. The relationship between the yield of the 146S fraction and the TCID50 of the virus preparations obtained was also evaluated as a mean to control and check the quality of the vaccine product. The results provided optimized conditions for vaccine production using cell suspensions and showed that there was a linear relationship between TCID50 and 146S fraction yield. Either TCID50 or the 146S fraction yield, or both could be used as parameters for quality monitoring during vaccine production. Using TCID50 reduced the number of steps involved in virus production while measuring 146S fraction yield was useful for quality control. However, more studies are required to evaluate the relative effectiveness of vaccines produced by virus cultures using either TCID50 or 146S fraction as quality monitoring tools.

Abstract
Henosepilachna vigintioctopunctata is a serious pest of Solanaceae and Cucurbitaceae in many Asian countries. RNA interference (RNAi) can effectively reduce transcript abundance in this beetle, offering opportunities to explore the biological function of specific genes. The white gene encodes a half-type ATP-binding cassette transporter that plays an essential role in tryptophan, guanine and uric acid transport across membranes. Mutations that disrupt the function of white are known to cause eye pigmentation phenotypes in many insect species. Here, we found evidence for five white gene paralogues present in H. vigintioctopunctata transcriptome datasets sequenced from a range of developmental stages. We individually knocked down each of the five white genes through the injection of corresponding double-stranded RNAs (dsRNAs) to the fourth-instar larvae to determine whether functional divergence has occurred. We found that injecting 1 μg dswhite3 caused compound eye colour of pupae and adults to develop as red/brown and brown, respectively, compared with black eyes in control beetles. Injection of 2 μg dswhite3 increased RNAi efficacy and produced a clearer eye colour phenotype. At both doses, the ocular diaphragm (a ring of black pigment surrounding each eye) did not change in the white3 RNAi hypomorphs. Moreover, our data revealed that injection of dswhite2 at the fourth-instar larval stage impaired the climbing ability of both male and female adults. Our results confirmed, for the first time, functional divergence of duplicated white genes in an insect species.

Abstract
Clostridium perfringens (C. perfringens) is a normal inhabitant in the gut of animals. It may proliferate rapidly in favorable conditions and produces lethal toxins. These toxins may cause lethal effects in the intestines and systemically it may cause enterotoxaemia. In disease conditions, the presence of C. perfringens CFU/g in fecal sample can be of diagnostic value. This study aims to determine the bacterial counts and predisposing factors of C. perfringens (targeting CPA gene) infection in addition to an in-vitro antimicrobial trial in entero-toxemic sheep in Pakistan. A total of 192 diarrheic sheep irrespective of age, gender and breed were selected and the CFU/g was determined from the fecal samples. The study showed that 34.9% of the samples had elevated level of bacterial count compared to the normal (104-107 CFU/g). Out of the total, 7.8% of the samples had subnormal bacterial count (CFU/g), while, 57.3% of the samples showed bacterial counts in the normal ranges. The confirmation of selectively isolated C. perfringens was done by amplification of 324bp CPA gene fragment using polymerase chain reaction (PCR). The in-vitro antimicrobial sensitivity trials showed that penicillin, ciprofloxacin and ceftriaxone are 100% efficacious against C. perfringens, while, bacitracin, ampicillin and amoxicillin were found to be least effective. The key determinants in this study which support the in-vivo growths of C. perfringens were; carbohydrate rich diet and overcrowding with the odds ratios (OR) of 5.44 and 2.26, respectively. This study concludes that C. perfringens is highly prevalent in sheep population of Pakistan. The incidence of enterotoxaemia can be minimized by controlling the factors which enhance its in-vivo growth. The diseased animal associated with elevated C. perfringens levels can be effectively cured using any one of the penicillin, ciprofloxacin and ceftriaxone.

Abstract
Toxigenic potential of different candidate fungi, isolated from rice straw feed of Degnala disease affected bovines was analyzed along with species, age, gender and seasonal prevalence. Of 1,536 cases, 104 (6.77%) showed positive signs with a significant association (p less than 0.05) between this disease and rice straw feeding, in buffaloes, and bovine aged over 1 year in the winter season. Complete blood count showed a marked increase in erythrocyte sedimentation rate and all white blood cells numbers, except lymphocytes in positive cases. There was a significant increase (p less than 0.05) in alanine amino transferase, aspirate amino transferase and alkaline phosphatase in the liver function test. At the same time, an increased value of creatinine was noted in the renal function test. For isolation and screening of toxigenic fungi, rice straw samples (n=40) being fed to the positive cases were processed further, and 85 fungal isolates were found, mainly of Aspergillus (57), Penicillium (10), Fusarium (04), Zygomycetes (03), Curvularia (01) and unidentified (10). All isolated fungi were subjected for mycotoxin production and only 11 showed mycotoxin-producing capability (including Aspergillus, Penicillium and Fusarium isolates) analyzed by thin layer chromatography and quantified through high performance liquid chromatography. It is concluded that all the fungi contaminating rice straw feed of Degnala affected animals were not toxigenic. This work will help in establishing major mycotoxin-producing fungi leading to the probable cause of Degnala disease in bovine.

Abstract
This study focuses on isolation of pathogenic bacteria from external and internal surfaces of cockroaches collected from houses and hospitals in Lahore. In total, 240 adult cockroaches were collected from houses and hospitals by hand or using sticky traps and food-bait traps. Cockroach species were identified, and microbial screening was done for external surfaces and gut tracts of cockroaches. Jaccard's index of similarity, Bray-Curtis' index of dissimilarity, and Shannon-Wiener's diversity index were used to measure the bacterial community diversity (all species of bacteria) in each habitat. Relative abundance and frequency were measured for each bacterial species on external and internal surfaces of cockroaches. Among human habitations, two major species of cockroaches were isolated, i.e., Periplaneta americana (P. americana) and Blattella germanica (B. germanica). Out of 240 cockroaches collected, 167 were P. americana and 73 were B. germanica. In total, 11 bacterial species were isolated, but no different bacterial load in each habitat was observed. The most common diagnostic bacterium isolated from the external surface of cockroaches was found to be Escherichia coli (10.31%). In contrast, the most common isolate from the internal gut tract of cockroaches was found to be Pseudomonas aeruginosa, with relative frequency of 19.96%. Jaccard's index of similarity of bacterial species found on cockroaches was highest (0.3125) in houses, whereas Bray-Curtis' index of dissimilarity was highest for hospitals (0.2174). The highest Shannon-Wiener's diversity index value was found in bacteria on cockroaches collected from the Punjab Institute of Cardiology (2.610632). No Salmonella typhi, Staphylococcus epidermidis, Enterobacter aerogenes, and Streptococcus pneumonia were found in the digestive tract of any cockroach.

Abstract
Water pollution has been a major concern for agrarian societies like Pakistan. Pharmaceutical industries are amongst the foremost contributor to industrial waste. Present study addresses the generation of oxidative stress caused by 2 months exposure to pharmaceutical wastewater in rats and their response to oral treatment with vitamin E, a potent antioxidant. The rats were randomized into five groups (n = 5) named as negative control, pharmaceutical wastewater (PEW) 100 %, PEW 10 %, PEW 1 %, and PEW 100 % + vitamin E. Oxidative damage in rats was evaluated by estimation of the activities of total superoxide dismutase (T-SOD), catalase (CAT), and the concentration of hydrogen peroxide (H2O2) in the liver, kidney, and blood/plasma. Exposure to pharmaceutical wastewater significantly decreased the activities of T-SOD and CAT and concentration of H2O2 in the liver and kidney and blood/plasma. Exposure to 100 % pharmaceutical wastewater exhibited a maximum decline in T-SOD activity, and activity was reduced to only 63.57 U/mL, 32.65, and 43.57 U/mg of protein in the plasma, kidney, and liver, respectively. Exposure to wastewater minimized activity CAT to 89.25 U/g of hemoglobin, 54.36, and 62.95 U/mg of protein in the blood, kidney, and liver, respectively. Treatment with vitamin E significantly increased the activity of T-SOD and CAT. However, increase in concentration of H2O2 was also observed in vitamin E exposed rats. Histopathology of the kidney revealed coagulative necrosis of renal epithelial cells and peritubular congestion. Endocardium showed infiltration of inflammatory cells and cellular breakdown in some areas. Lung sections exhibited atelectasis and emphysema of alveoli suggesting decline in lung function. The anatomy of the liver was also compromised due to severe degeneration and cellular swelling. The present study concluded that pharmaceutical wastewater induced severe oxidative stress in Wistar rats and ensued in histopathological lesions in several vital organs suggesting its high toxicity. Non-enzymatic antioxidant vitamin E may ameliorate oxidative stress induced by pharmaceutical wastewater.

Abstract
Pharmaceutical industries are amongst the foremost contributor to industrial waste. Ecological well-being is endangered owing to its facile discharge. In the present study, heavy metals and organic contaminants in waste water were characterized using atomic absorption spectrophotometer and GC-MS, respectively. Mutagenicity and genotoxic potential of pharmaceutical waste water were investigated through bacterial reverse mutation assay and in vitro comet assay, respectively. Ames test and comet assay of first sample were carried out at concentrations of 100, 50, 25, 12.5, 6.25 % v/v effluent with distilled water. Chromium (Cr), lead (Pb), arsenic (As), and cadmium (Cd) were found in high concentrations as compared to WHO- and EPA-recommended maximum limits. Arsenic was found to be the most abundant metal and its maximum concentration was 0.8 mg.L(-1). GC-MS revealed the presence of lignocaine, digitoxin, trimethoprim, caffeine, and vitamin E in waste water. Dose-dependent decrease in mutagenic index was observed in both strains. Substantial increase in mutagenicity was observed for TA-100, when assay was done by incorporating an enzyme activation system, whereas a slight increase was detected for TA-102. In vitro comet assay of waste water exhibited decrease in damage index and percentage fragmentation with the increase in dilution of waste water. Tail length also decreased with an increase in the dilution factor of waste water. These findings suggest that pharmaceutical waste water being a mix of different heavy metals and organic contaminants may have a potent mutagenic and genotoxic effect on exposed living organisms.

Abstract
Aim of the present study was to characterise and evaluate probiotic potential of lactobacilli isolated from indigenous poultry. Lactobacilli were isolated from poultry droppings and identified by genus specific polymerase chain reaction and 16S rRNA gene sequencing. Isolates were characterised in vitro by their ability to tolerate low pH and bile salts, phytase activity, antimicrobial activity, antibiotic susceptibility profile, and autoaggregation and coaggregation with poultry gut pathogens. In vivo evaluation of selected isolates was done by their effect on the body weight gain and immune response of broiler chicks. Total of 90, one-day old chicks, were randomly divided in 9 groups and given selected lactobacilli alone and in combinations (108 cfu/bird, daily) from day 7 to day 35. Body weight gain and humoral immune response to New Castle Disease Virus (NDV) vaccine were determined weekly. Three lactobacilli isolates (SMP52, SMP64 and SMP70) were selected as potentially probiotic bacteria on the basis of in vitro characterisation and identified as Lactobacillus crispatus, Lactobacillus casei and L. crispatus, respectively. Chicks supplemented with 'SMP52', 'SMP64', 'SMP70' and 'SMP64+SMP70' and a commercial probiotic product (Protexin) showed significantly higher mean weight gain per bird (1,584±35.2, 1,629±30.6, 1,668±34.7, 1,619±29.5 and 1,576±31.7 g/bird, respectively) as compared to negative control group (1,394±26.7 g/bird), on day 35. SMP 70 also showed significantly higher geometric mean titre against NDV vaccine at day 21 as compared to negative control. It is concluded that L. crispatus SMP52, L. casei SMP64 and L. crispatus SMP70 are potential probiotic candidates which alone or in different combinations may increase body weight of broilers.
