    Abstract In the present study we aimed to establish the seroprevalence of T. gondii and N. caninum in stray and domiciled cats from the municipality of Patos, Paraíba state, Brazil. Blood samples were collected from 201 animals: 132 domiciled cats and 69 stray cats. An epidemiological questionnaire was conducted with all cat owners. Indirect immunofluorescent antibody test (IFAT) was performed at cut-offs of 1:16 and 1:50 for T. gondii and N. caninum, respectively. Overall prevalence of seroreagent cats for T. gondii was 43.8%. We found a prevalence of 47.7% in domiciled cats and 36.2% in stray cats. Antibody titers ranged from 1:16 (cut-off) to 1:8192; 1:128 was the most frequent titer. No statistical difference was observed between domiciled cats and stray cats. Correlation was verified between seroreagent for T. gondii and age and hunting habit (P<0.05). No animals tested seroreagent for N. caninum. It was possible to conclude that there is high prevalence of cat seroreagent for T. gondii and that N. caninum is not present in cats from the area studied.

    Abstract Avaliou-se a eficácia da Typha domingensis (taboa) e da Operculina hamiltonii (batata-de-purga) in natura sobre nematóides gastrintestinais de caprinos, naturalmente infectados, em clima semi-árido. Foram utilizados 30 caprinos da raça Moxotó, e o rizoma da taboa e a raiz da batata-de-purga, avaliados através da fitoquímica. As fezes foram coletadas nos dias zero, sete e 25, após, o tratamento da contagem de OPG. Os animais foram distribuídos inteiramente ao acaso, com cinco tratamentos e seis repetições. Grupo I tratado com Moxidectina 0,2% em dose única de 0,5 mg Kg-1; o Grupo II tratado com Taboa na dose (10 g 20 Kg-1 peso vivo); Grupo III com batata-de-purga na dose de 9 g 20 Kg-1 p.v.; Grupo IV tratado com taboa 10 g 20 Kg-1 p.v. associada a batata 9 g 20 Kg-1 p.v. durante três dias consecutivos, todos administrados oralmente e o Grupo V como grupo controle. Os grupos tratados apresentaram redução no número médio de OPG aos 7 e 25 dias pós-tratamento, quando comparado com o grupo controle no respectivo período, sendo a batata-de-purga com maior redução aos 7 e a taboa aos 25 dias. A maior eficácia foi da batata-de-purga de 84% e 70%, nos dias 7 e 25 pós-tratamento. Verificou-se que a batata-de-purga foi eficaz no controle de nematóides gastrintestinais de caprinos no clima semi-árido e que a taboa associada com a batata tem potencial para serem utilizadas em programas alternativos de controle parasitário. The effectiveness of Typha domingensis ("taboa") and Operculina hamiltonii ("batata-de-purga") in natura was evaluated on gastrointestinal nematodes of goats, naturally infected, in the semi-arid region. Thirty Moxotó goats were used, and the rhizome of "taboa" and the root of "batata-de-purga" were analyzed through phytochemistry. Feces were collected on days zero, seven and 25 after the treatment for FECs. The distribution of animals was completely at random, with five treatments and six replicates. Group I was treated with Moxidectin 0.2% in a single dose of 0.5 mg kg-1; Group II was treated with "taboa" at the dose of 10 g 20 Kg-1 body weight; Group III was treated with "batata-de-purga" at the dose of 9 g 20 Kg-1 b.w.; Group IV was treated with "taboa" at 10 g 20 Kg-1 b.w. associated with "batata-de-purga" at 9 g 20 Kg-1 b.w. during three consecutive days. All treatments were orally administered and Group V was used as control. Treated groups showed a reduction in the average number of FECs at seven and 25 days post-treatment when compared to the control group in the respective period; "batata de purga" had a greater reduction at seven days, while "taboa" showed a more pronounced reduction at 25 days. The highest effectiveness was observed for "batata de purga": 84% and 70% at seven and 25 days post treatment. "Batata-de-purga" was effective in controlling gastrointestinal nematodes of goats in the semi-arid climate and "taboa" associated with "batata de purga" have the potential to be used in alternative programs for parasite control.

    Abstract O experimento in vitro foi realizado para avaliar a ação do extrato etanólico das folhas do melão-de-São-Caetano (Momordica charantia L.) sobre o desenvolvimento de ovos e motilidade de larvas de nematóides gastrintestinais de caprinos. As larvas foram obtidas de coproculturas e a recuperação de ovos foi feita pela técnica dos quatro tamises, a partir de fezes de caprinos naturalmente infectados da mesorregião do Sertão Paraibano. O extrato foi utilizado nas diluições de 50; 25; 12,5; 6,25 e 3,12% para ambos os testes e como controle positivo e para controle negativo, utilizou-se água destilada estéril. As placas foram examinadas ao microscópio óptico para contagem dos ovos em desenvolvimento e larvas móveis e imóveis, após 24, 48 e 72 horas de incubação. As concentrações do extrato etanólico de M. charantia e os tratamentos controle negativo e positivo diferiram quanto ao número de ovos inviáveis. No teste de motilidade larval as concentrações acima de 12% apresentaram médias significativas quanto ao número de larvas inviáveis. Nas condições ensaiadas a M. charantia apresentou atividade ovicida e larvicida. The experiment in vitro was performed to evaluate the action of the ethanolic extract of "melão de São Caetano" (Momordica charantia L.) leaves on the development of eggs and motility of larvae of gastrointestinal nematodes from goats. The nematode larvae were obtained from coproculture and the recovery of eggs was done in sieves, from feces of naturally infected goats from the Mesoregion of Paraíba State. The extract was used at the dilutions of 50, 25, 12.5, 6.25 and 3.12% for both tests and as positive control; for negative control, sterile distilled water was used. The plates were examined under optical microscope to count the eggs in development and mobile larvae after 24, 48 and 72 h of incubation. The concentrations of M. charantia ethanolic extract and the negative and positive controls differed as to the number of eggs that were not viable. In the larval motility test, concentrations higher than 12% had significant means as to the number of larvae that were not viable. Under the tested conditions, M. charantia showed larvicidal and ovicidal activity.

    Abstract Devido ao aparecimento de populações de parasitos resistentes, as drogas farmacêuticas, alternativas de controle, estão sendo pesquisadas utilizando plantas medicinais. O objetivo deste estudo foi avaliar a atividade antibacteriana e realizar a análise fitoquímica do extrato etanólico de duas espécies do semi-árido paraibano, Solanum paniculatum Lam. e Operculina hamiltonii (G. Don) D. F. Austin & Staples. As referidas espécies são muito utilizadas pela população rural contra verminoses gastrintestinais de ovinos. A prospecção fitoquímica foi obtida a partir dos extratos etanólicos para análise dos constituintes químicos existentes nas duas espécies. As análises dos extratos indicaram a presença de taninos flobabênicos, flavononóis, flavononas e alcalóides em ambas as espécies. A atividade antibacteriana foi determinada inicialmente pelo método de difusão em cavidade. A espécie S. paniculatum apresentou atividade contra Staphylococcus aureus (ATCC 12692), Escherichia coli (ATCC 25922) e Pseudomonas aeruginosa (ATCC 15442), no entanto O. hamintonii não demonstrou atividade contra as linhagens bacterianas testadas. The emergence of resistant parasite populations has led to the study of pharmaceutical drugs, which represent an alternative control. This study aimed to evaluate the antibacterial activity and to perform the phytochemical analysis of the ethanol extract from two species belonging to the semi-arid region of Paraíba State, Brazil: Solanum paniculatum Lam. and Operculina hamiltonii (G. Don) D. F. Austin & Staples. Such species have been largely used by the rural population against ovine gastrointestinal helminthes. Phytochemical prospection was obtained from ethanol extracts for analysis of chemical compounds present in both species. Extract analyses indicated the presence of condensed tannins, flavonols, flavanones, and alkaloids in both species. The antibacterial activity was initially determined by the cavity method. The species S. paniculatum had activity against Staphylococcus aureus (ATCC 12692), Escherichia coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC 15442); however, O. hamintonii did not present activity against the tested bacterial strains.
