The indiscriminate use of anthelmintics has resulted in the establishment parasite resistance. Thus, this study aimed to evaluate vitro antiparasitic effect plant extracts on Haemonchus contortus sheep and vivo Strongyloides venezuelensis Rattus norvegicus. from Piper tuberculatum, Lippia sidoides, Mentha piperita, Hura crepitans Carapa guianensis, produced at different research institutions, were chemically analyzed evaluated through egg hatch test (EHT) larval development (LDT) H....
Anthelmintic resistance is a worldwide concern in small ruminant industry and new plant-derived compounds are being studied for their potential use against gastrointestinal nematodes. Mentha piperita, Cymbopogon martinii schoenanthus essential oils were evaluated developmental stages of trichostrongylids from sheep naturally infected (95% Haemonchus contortus 5% Trichostrogylus spp.) through the egg hatch assay (EHA), larval development (LDA), feeding inhibition (LFIA), exsheathment (LEA)....
The most challenging obstacles to testing products for their anthelmintic activity are: (1) establishing a suitable nematode in vitro assay that can evaluate potential product use against parasitic of interest and (2) preparation extracts be redissolved solvents are miscible the test medium at concentrations well tolerated by system used screening. nematodes as screening is hindered difficulty keeping them alive long periods outside host need keep infected animals sources eggs or adults when...
Haemonchus contortus and Trichostrongylus colubriformis are the most important gastrointestinal nematodes causing serious losses in sheep production of tropical subtropical regions. Prophylaxis nematode infections is based on anthelmintics use, but their frequent administration selects multiple-resistant parasites. To evaluate how situation has changed over last decades, anthelmintic resistance status flocks was assessed current study compared to previous surveys. In each one 15 evaluated,...
This study was carried out to evaluate the immune response and impact of Trichostrongylus colubriformis infections on performance growing Santa Ines lambs. Thirty male lambs, 3–4 months age, were maintained in individual pens restrictively randomised by weight into 3 treatment groups: (1) infected group, artificially with 2500 T. larvae, three times a week, for 13 weeks, fed ad libitum; (2) Pair-Fed Group, non-infected same amount food consumed animal class previous day; (3) control libitum....
A criação de ovinos e caprinos depende um manejo eficiente, devido, principalmente, ao prejuízo causado por parasitos em animais susceptíveis. Vários fatores colaboram para que os tolerem as infecções parasitárias, como: genética, nutrição, estado fisiológico idade. O grave problema pela resistência anti-helmíntica promoveu a difusão técnicas alternativas controle parasitário. Dentre essas novas estratégias incluem-se adoção do tratamento parcial seletivo com o método FAMACHA, fitoterapia,...
Abstract In this paper we report the occurrence of zoonotic species Cryptosporidium (C. ubiquitum and C. parvum subtype IIaA15G2R1) host-specific Giardia duodenalis genotype E in a sheep farm from Brazil. Fecal specimens were collected 100 animals screened for presence G. spp. by enzyme immunoassay (EIA) polymerase chain reaction (PCR). Restriction fragment length polymorphism (RFLP) sequence analysis selected samples was used to confirm characterize isolates. Of specimens, 34 positive (34%)...
Abstract Understanding the immunological basis of resistance to gastrointestinal nematode infections in livestock is important order develop novel methods parasite control such as vaccination or genetic selection for resistance. The present study aimed investigate differences immune response between resistant Santa Ines and susceptible Ile de France sheep breeds natural Haemonchus contortus infection. Parasitological parameters, humoral immunity, local circulating cellular responses were...
This study aimed to evaluate the potential benefits and feasibility of adding dried ground grape pomace concentrate fed lambs experimentally infected with Haemonchus contortus. Eighteen male Santa Inês lambs, recently weaned, were housed in individual pens allocated into two groups based on their body weight. The supplemented group (n = 9) initially received a diet composed 50% hay concentrate. Subsequently, these animals gradually adapted until its final inclusion reached 20%. control...
