A study on the influence of selected Indian herbal active principles on enhancing the immune system in Fenneropenaeus indicus against Vibrio harveyi infection

The use of medicinal plants as immunostimulants in aquaculture: A review

“…A combination of essential oils from the herbs (Thymus vulgaris, Salvia officinalis, Eucalyptus globules and Mentha piperita) had potent antibacterial effects against a range of bacterial species (Staphylococcus aureus, Escherichia coli and Pseudomonas aeroginosa) (Mousavi et al, 2011). A diet mixture of equal proportions of five herbs (Acalypha indica, Hygrophila spinosa, Picrorhiza kurooa, Tinospora cordifolia and Zingiber officinale) improved the total hemocyte count, phagocytosis, phenol oxidase activity, haemagglutinin activity and bacterial clearance of Indian white prawns, Fenneropenaeus indicus (Rajeswari et al, 2012). A mixture of equal proportions of six herbs and plant materials in diets enhanced or impaired enzyme activity (Lin et al, 2006).…”

AKTIVITAS ANTIBAKTERI PENYEBAB VIBRIOSIS TERHADAP UDANG WINDU DARI EKSTRAK HERBAL MANGROVE Sonneratia alba DAN Bruguiera gymnorrhiza

“…Penggunaan bahan alam termasuk mangrove dan tanaman asosiasinya untuk penanggulangan penyakit di bidang perikanan mulai dirintis meskipun masih terbatas pada skala laboratorium di antaranya sebagai antibakteri (Velmurugan & Citarasu, 2010;Rajasekar et al, 2011;Rajeswari et al, 2012).…”

Influence of Agathi grandiflora active principles inhibit viral multiplication and stimulate immune system in Indian white shrimp Fenneropenaeus indicus against white spot syndrome virus infection

“…The screening of plant extracts and natural products for antimicrobial activity has shown that higher plants represent a potential source of new anti-infective agents [33] as well as serve in drug discovery from natural products for primary lead compounds. The herbal extracts having the characteristics of antimicrobial and immunostimulants were able to decrease the mortality and reduce the pathogenic load against pathogenic challenge by improving immune system in fishes and shrimps [18,24]. In the present study, the ethyl acetate and methanolic extract of A. grandiflora was effectively suppressed the WSSV multiplication and improved the immune system in F. indicus against V. harveyi challenge when compared to the other herbal extracts.…”

“…The WSSV infection was confirmed by using WSSV two steps PCR in Penaeus monodon fed with antiviral/immunostimulant herbal active principles [12,35]. Rajarajeswari et al [24] studied the immunostimulant activity of the herbals including Acalypha indica, Hygrophila spinosa, Picrorhiza kurooa, Tinospora cordifolia and Zingiber officinale in F. indicus against V. harveyi.…”

“…The herbal extract incubated HLF was used for testing the antibacterial assay with Vibrio harveyi [24]. One hundred micro litre of immunostimulated HLF was incubated again with 100 ml V. harveyi bacterial culture 1 Â 10 3 cfu ml À1 for 30 min at 25 ± 2 C. Control experiments were performed for V. harveyi incubated with HLF without incubation of herbal extracts.…”
