Medicinal plants have played a pivotal role in the primary healthcare and formed the basis of traditional systems of medicines. They are effective in the treatment of infectious diseases while simultaneously mitigating many side effects that are often associated with synthetic antimicrobials. A disease that caused through pathogenic microorganisms is the major cause of deaths across the world. Increasing cases of drug resistance, unwanted side effects of existing antibiotics and the reappearance of earlier known infections lead to the need for new, safe and effective antimicrobial agents[1-3]. Thus, phytoconstituents such as phenolics are being considered to be safe and provide lesser chances for microbes to develop drug resistance. Oxidative stress is mainly caused by the reactive oxygen species (ROS) such as hydroxyl radical (·OH), peroxide (ROO·) and superoxide radicals (O2· ). These reactive oxygen species are classes of compounds formed from oxygen metabolism, and are able to cause severe damage to cells and tissues. The effect of oxidative stress is linked to cardiovascular diseases, cancer, inflammatory diseases and many other health issues. Antioxidants are significant agents in reducing oxidative stress which damages cells and biological molecules[4]. Natural antioxidants such as bioactive flavonoids are of great ARTICLE INFO ABSTRACT

Aquatic insects are macroinvertebrates that live on or associated with bottom of freshwater bodies[1]. Their pivotal role in nutrients circulation cannot be over emphasized in aquatic environment. Aquatic invertebrates are the link between unobtainable nutrients in detritus and protein materials in fishes[1,2]. Their role in fasttracking the breakdown of putrefying organic material into smaller inorganic forms such as nitrate and phosphate is also well documented[3]. These nutrients are usually utilized by aquatic plants in the ecosystem. Aquatic insects commonly used as biological indicator have been effective in monitoring environmental pollution and water quality[4,5]. The sensitivity and forbearance to environmental perturbation exhibited by aquatic insects vary considerably among orders and species. The composition and distribution of aquatic insect at any given point in a water course is a reflection of its water quality[5]. This makes aquatic insect a valuable tool in pollution and water quality assessment. Species richness of aquatic insects can be influenced by physicochemical parameters [temperature, dissolve oxygen (DO), biochemical oxygen demand (BOD) and turbidity] of water.

Marine macro-algae also called as seaweeds are rich in minerals, polyunsaturated fatty acids and vitamins; hence it could potentially be exploited for both human and animal health applications[1,2]. Around 600 secondary metabolites have been so far identified from seaweeds[3] and compounds derived from them are associated with broad range of biological activities[4,5]. The emergence of antibiotic resistant microorganisms in aquaculture is a key obstacle to their extensive use. The residue of these chemicals in aquaculture products has also been reported as a serious concern for consumers[6]. The prevention and treatment of these infectious agents by applying natural products from marine organisms appears to be a possible alternative source[7]. The desirable physiological and morphological characteristics of erythrocytes made them an effective tool in drug testing and delivery[8,9]. Oxidative damage to the erythrocyte membrane leads to hemolysis and compounds having antioxidant properties have long term action on hemolysis[10]. Phytochemicals such as flavonoids, polyphenols and phlobatanins inhibited proliferation of cancer cells and influenced anti-inflammatory responses[11]. Sargassum wightii (family: Phaeophyceae) (S. wightii) is widely distributed in the southern coasts of India, harbors good amount of flavonoids and is an ideal target for medical and industrial applications[12]. Sargassum sp. contains various secondary metabolites with biological activities[13] and has also been used in the treatment of chronic bronchitis, hypertension, edema, goiter and tuberculosis of lymph nodes[14]. Gracilaria verrucosa (family: Rhodophyceae) (G. verrucosa) prevalent in Indian coast is known for its food value. The phycocolloids have a high growth rate owing to temperature tolerance and are rich in primary and secondary metabolites[15]. Gracilaria species have small esterification cell wall and phycocolloids, the main source of agar α-(1,4)-3,6-anhydroL-galactose and β-(1,3)-D-galactose that are important for the industrial and biotechnological applications[16,17]. With this backdrop, the present study has been undertaken to compare the in vitro biological activity of solvent extracts of S. wightii and G. verrucosa. ARTICLE INFO ABSTRACT

Objective: To investigate the chemical composition, in vitro antibacterial and antifungal activity of Mentha longifolia L. essential oils using aqueous extract. Methods: Mentha longifolia L. essential oils were extracted using hydrodistillation with Clevenger apparatus for 3 h and the yield of the essential oil was calculated. Essential oils were qualitatively and quantitatively analyzed with gas chromatography and gas chromatographymass spectrometer. For these essential oils, antibacterial and antifungal activity against human pathogens were evaluated. Results: Nineteen chemical constituents representing 99.72% of the essential oil were found, comprising menthone (39.55%), isopulegone (30.49%), eucalyptol (10.38%), and α-terpineol (3.15%); these were major components, and others were minor components. The essential oil showed strong antibacterial activity against Staphylococcus aureus [(35.24 � 0.13) mm], Enterococcus faecalis [(32.12 � 0.12) mm] and Bacillus cereus [(30.06 � 0.04) mm], as well as antifungal activity against Aspergillus flavus [(38.02 � 0.06) mm], Alternaria alternaria [(35.26 � 0.12) mm], and Penicillum spp [(34.14 � 0.02) mm]. Conclusions: It seems that the essential oils derived from the Mentha longifolia L. species could be used as a natural source of antimicrobial agents.

Tropical freshwater fishes such as Tilapia zillii (T. zillii) and Clarias gariepinus (C. gariepinus) serve as definitive/transport or intermediate host in the developmental cycle of many species of protozoan, metazoan and crustacean parasites[1]. Parasites are invertebrate organisms; some are free-living and can become opportunistic parasites while the obligate parasites require hosts for their survival and reproduction. Both opportunistic and obligate parasites are found in fish hosts but most parasitic diseases in fish are generally caused by obligate parasites[2]. In fisheries, some parasites may be highly pathogenic and contribute to high fish mortalities and economic losses or threaten the abundance and diversity of indigenous fish species[3,4]. T. zillii and C. gariepinus are the most common sources of protein for humans and other animals in the tropics[5-7]. Fish interacts with the various levels of food chain and influences the structures of rivers, lakes, streams and estuaries, since they are usually restricted to particular modes of life related to their food sources and reproductive requirements[8,9]. Like other animals, fish is also afflicted by endoand ectoparasites, especially protozoans and helminths causing heavy mortality[10]. Fish parasites and diseases constitute one of the most important problems confronting fish farmers today[11]. Pathological conditions resulting from parasites and diseases cause high magnitude of epidemics under crowded and other unnatural conditions[12].
