Effect of single and binary combinations of plant-derived molluscicides on different enzyme activities in the nervous tissue of Achatina Fulica.
Journal of applied toxicology : JAT, 2003Co-Authors: I. G. Rao, Amrita Singh, V. K. Singh, Dhirendra SinghAbstract:Effect of single and binary treatments of plant-derived molluscicides on different enzymes--acetylcholinesterase (AChE), lactic dehydrogenase (LDH) and acid/alkaline phosphatase (ACP/ALP)--in the nervous tissue of the harmful terrestrial snail Achatina Fulica were studied. Sublethal in vivo 24-h exposure to 40% and 80% LC(50) of Azadirachta indica oil, Cedrus deodara oil, Allium sativum bulb powder, Nerium indicum bark powder and binary combinations of A. sativum (AS) + C. deodara (CD) and CD + A. indica (AI) oils significantly altered the activity of these enzymes in the nervous tissue of Achatina Fulica. The binary treatment of AS + CD was more effective against AChE, LDH, and ALP than the single ones. However, binary treatment of AI + CD was more effective against ALP.

Toxic effect of single and binary treatments of synthetic and plant-derived molluscicides against Achatina Fulica.
Journal of applied toxicology : JAT, 2002Co-Authors: I. G. Rao, D. K. SinghAbstract:The toxic effect of single and binary treatments of synthetic and plant-derived molluscicides was studied against the harmful terrestrial snail Achatina Fulica. In single treatments, among the synthetic molluscicides Snail Kill and cypermethrin were potent, whereas Cedrus deodara oil was more toxic among molluscicides of plant origin against A. Fulica. In binary treatments, a combination of Cedrusdeodara + Alliumsativum was more toxic. The toxicities of these single and binary treatments of synthetic and plant-derived molluscicides were dose and time dependent.

Fulicin regulates the female reproductive organs of the snail, Achatina Fulica.
Peptides, 2000Co-Authors: Yuko Fujisawa, Katsuyoshi Masuda, Hiroyuki MinakataAbstract:Abstract Fulicin is a d -amino acid-containing neuropeptide that has been thought to control male copulatory behavior in the land snail, Achatina Fulica . In the present study, we demonstrated that the vagina and the oviduct of Achatina were densely innervated by fulicin-like immunoreactive neuronal fibers. We confirmed that fulicin was actually present in the vagina by mass spectrometry. Furthermore, fulicin showed a profound excitatory effect on contractions of the vagina and the oviduct. These results suggest that fulicin controls female egg-laying behavior as an excitatory neuropeptide regulating the female reproductive organs of the snail.

fulicin a novel neuropeptide containing a d amino acid residue isolated from the ganglia of Achatina Fulica
Biochemical and Biophysical Research Communications, 1991Co-Authors: Noriyuki Ohta, Hiroyuki Minakata, Kyosuke Nomoto, Ichiro Kubota, Yojiro Muneoka, Toshifumi Takao, Yasutsugu Shimonishi, Yoshimi Yasudakamatani, Makoto KobayashiAbstract:Abstract A novel pentapeptide containing a D-amino acid residue was purified from the central ganglia of the African giant snail Achatina Fulica Ferussac, and it was named fulicin. The primary structure of the peptide was determined to be Phe- d -Asn-Glu-Phe-Val-NH2. Fulicin potentiated tetanic contraction of the penis retractor muscle of this snail at very low concentrations, and also showed modulatory actions on the activity of the buccal and ventricular muscles and the central ganglionic neurons.

APGW-amide as an inhibitory neurotransmitter of Achatina Fulica Ferussac.
Biochemical and biophysical research communications, 1991Co-Authors: Guo Jun Liu, Divina E. Santos, Hiroshi Takeuchi, Yoshimi Kamatani, Hiroyuki Minakata, Kyosuke Nomoto, Ichiro Kubota, Tetsuya Ikeda, Yojiro MuneokaAbstract:Abstract APGWamide (L-Ala-L-Pro-Gly-L-Trp-NH2) was purified from the ganglia of an African giant snall ( Achatina Fulica Ferussac). This peptide inhibited (hyperpolarized) more than half of the Achatina neurone types tested. This produced an outward current with the membrane conductance increase of RAPN (right anterior pallial neurone) under voltage clamp. The ED50 of the peptide was 6.2 × 10−6 M (95% confidence limit: 5.0 – 7.8 × 10−6 M) and the Emax was 3.9 ± 0.2 nA. The effects were due to a membrane permeability increase to K+. The peptide is proposed as an inhibitory neurotransmitter of the Achatina neurones.

Achatina Fulica Bowdich (1822) a new host of Cryptosporidium (Apicomplexa, Cryptosporidiidae) species
Revista brasileira de parasitologia veterinaria = Brazilian journal of veterinary parasitology : Orgao Oficial do Colegio Brasileiro de Parasitologia , 2008Co-Authors: Francimar Fernandes Gomes, Nicole Brand Ederli, De Oliveira FcAbstract:With the objective of isolate Cryptosporidium spp. in Achatina Fulica s feces, 50 mollusks were collected in nine neighborhoods of the municipal of Campos dos Goytacazes, RJ to the observation of oocysts in feces. The snails were put in individuals containers and fed with water and green vegetables ad libitum until be collected a gram of feces per animal. The samples were conditioned in tubes with formalin 10% and later smear of feces were made and dyed by Ziechl-Neelsen modified technique. Of the 50 samples examined, 26 (52%) were positive for the presence of oocysts of Cryptosporidium spp. The morphology and morphometry of the oocysts showed that are a great morphologic variability. Considering the obtained results, the mollusk Achatina Fulica is a host of Cryptosporidium species and can participate in the epidemic chain of the cryptosporidiosis.

Antimicrobial proteins of Snail mucus (Achatina Fulica) against Streptococcus mutans and Aggregatibacter actinomycetemcomitans Antimicrobial proteins of Snail mucus (Achatina Fulica) against Streptococcus mutans and Aggregatibacter actinomycetemcomit
2014Co-Authors: Dosen Fakultas, Kedokteran GigiAbstract:Background: Achasin and mytimacin-AF are proteins of snail mucus (Achatina Fulica) which have antimicrobial activity. Snail mucus is suspected to have other proteins which have antimicrobial activity against Streptococcus mutans and Aggregatibacter actinomycetemcomitans the oral pathologic bacteria. Purpose: The study were aimed to characterize the proteins of snail mucus (Achatina Fulica) that have antimicrobial activities to Streptococcus mutans and Actinobacillus actinomycetemcomitans, and to compared the antimicrobial effect of achasin and mytimacin-AF. Methods: The sample of study was the mucus of snails which were taken from Yogyakarta Province. The isolation and characterization of protein were conducted by using SDS-PAGE method, electroelution, and dialysis. Nano drop test was conducted to determine protein concentration. The sensitivity test was conducted by using dilution test, and followed by spectrophotom etry and paper disc diffusion tests. results: The study showed that proteins successfully characterized from snail mucus (Achatina Fulica) were proteins with molecular weights of 83.67 kDa (achasin), 50.81 kDa, 15 kDa, 11.45 kDa (full amino acid sequence of mytimacin-AF) and 9.7 kDa (mytimacin-AF). Based on the dilution test, Achasin had better antimicrobial activities against Streptococcus mutans, while mytimacin-AF had better antimicrobial activities against Aggregatibacter actinomycetemcomitans. But the paper disc diffusion test result showed that Achasin had antimicrobial activities against Streptococcus mutans and Aggregatibacter actinomycetemcomitans, while mytimacin-AF had no antimicrobial activities. Conclusion: The proteins with molecular weights of 50.81 kDa, 15 kDa, 11.45 kDa were considered as new antimicrobial proteins isolated from snail mucus. Achasin, had better antimicrobial activities against Streptococcus mutans, while mytimacin-AF had better antimicrobial activities against Aggregatibacter actinomycetemcomitans.
