ArticleItem Open Access Efficacy of Allium sativum Linn. against strongyles in naturally infected sheep(Elsevier, 2011-12) Lakshmi, K. Navaneetha; Veerakumari, L.; Raman, M.; TANUVASHelminth infection is a major cause for reduced productivity in livestock. Strongyles are the most common and the most pathogenic of the helminth parasites of sheep and goat. Indiscriminate use of chemical anthelmintics to control helminths has resulted in parasites refractory to chemotherapy. Therefore, phytomedicine with anti-parasitic properties offer an effective alternative. The present investigation was carried out to assess the efficacy of Allium sativum bulb extract (AsBE) at various concentrations (10, 20 and 30 mg ml-1) against strongyle infection in sheep. The eggs per gram (EPG) of faeces were found to be within the range 425-435 prior treatment in the different groups (Groups I, II and III), which significantly reduced post-treatment (PT). The faecal egg count reduction percentage (FECR %) calculated were 96.12 ± 1.70, 98.91 ± 1.52 and 98.72 ± 1.21 %, respectively, in Groups I, II and III PT which received AsBE orally @ 10, 20 and 30 mg ml-1. The haematological and biochemical profiles revealed anaemia and hypoproteinaemia in the infected groups. However, after treatment with AsBE, the infected sheep showed restoration of their haematological and biochemical profiles. It was concluded that AsBE could find application in anthelmintic therapy in veterinary practiceArticleItem Open Access Molecular Characterization of Coimbatore Isolates of Emimeria Tenella by ITS-1 Based Nested PCR(Indian Vet. J., 2013-11) Thenmozhi, V.; Sureshkumar, M.; Raman, M.; Gomathinayagam, S.; Veerakumari, L.; TANUVASOf the 45 samples tested 21 samples (46.6%) of the samples were positive for Eimeria tenella. Sequences of Eimeria tenella ITS-l regions showed 100% homology with the Houghton strain and >90 homology was observed with the American, European and Chinese strains of tenella. These variations among the study isolates indicate diversity of eld isolates within the composite broiler belt. This strains needs to be further veried for the strain variation in E. tenella for the development of drug and vaccine to overcome the drug and vaccine resistance problemOtherItem Open Access Prevalence of Paramphistomes in Sheep Slaughtered at Perambur Slaughter House in Chennai(TANUVAS, 2016-02) Vasanthi, P.; Veerakumari, L.; Soundararajan, C.ArticleItem Open Access Prevalence Of Rumen Paramphistomes In Sheep Slaughtered At Perambur Slaughter House in Chennai, Tamil Nadu(2018-07) Vasanthi, P.; Veerakumari, L.; Soundararajan, C.; TANUVASA total of 9600 sheep were examined for the presence of paramphistomes at Perambur slaughter house, Chennai, Tamil Nadu from January 2014 to December 2015. Paramphistomes were identified as Cotylophoron cotylophorum, Fischoederius elongatus, Gastrothylax crumenifer and Paramphistomum cervi. Of the 9600 animals examined, 10.30% (989/9600) had paramphistome infection. Among the sex, females were highly infected 73.10% than the males 26.90%. Among the season, highest prevalence observed in northeast monsoon (42.16%) followed by south-west monsoon (40.65%) and very low level during winter (10.82%) and summer (6.37%). Among the species of the parasites, highest infection of C. cotylophorum (76.25%) followed by F. elongatus (12.72 %) G. crumenifer (8.71 %) and very low level of P. cervi (2.32 %) was recorded. Among the paramphistomes, the prevalence of C. cotylophorum occurs in all the months except during February, March and May and with highest prevalence during August and October. Prevalence of F. elongatus was also recorded in all the months except during February, March, May, September and December of the year 2014 and November, December of the year of 2015. Gastrothylax crumenifer was found only during the month of January and September to November of the year 2014, January, February and August to December of the year 2015 and with highest level 70.50 % (n = 11253) during November 2014. Similarly, Paramphistomum cervi found only during the month of January, October and November of 2014 and January, February, August, September and November with highest level 24.27 % (n = 3004) during December 2015.
