Tujuan dari penelitian ini adalah untuk menentukan prevalensi dan derajat infeksi cacing saluran pencernaan pada itik petelur di dua kondisi lingkungan yang berbeda. Sampel feses diperiksa dengan metode sedimentasi dan metode apung kemudian dilanjutkan dengan menghitung telur cacing per gram tinja dengan metode Mc Master. Hasil menunjukkan bahwa 22,9% (8/35) itik petelur di Dusun Keper terinfeksi oleh Capillaria sp., dan Echinostoma revolutum, dengan rata-rata derajat infeksi sebsar 52,50 ± 41,662, sedangkan 31,4% (11/35) itik petelur di Dusun Markolak terinfeksi oleh Capillaria sp., Echinostoma revolutum, dan cacing dari kelas cestoda, dengan rata-rata derajat infeksi sebesar 155,45 ± 166,395. Infeksi bersifat tunggal maupun campuran. Analisis terhadap prevalensi dan derajat infeksi cacing saluran pencernaan itik petelur menunujukkan hasil yang tidak signifikan (p>0,05) antara Dusun Keper dan Dusun Markolak.

Age Structured Model

SummaryEpidemiological modelling can be a useful tool for the evaluation of parasite control strategies. An age-structured epidemiological model of intestinal helminth dynamics is developed. This model includes the explicit representation of changing worm distributions between hosts as a result of treatment, and estimates the morbidity due to heavy infections. The model is used to evaluate the effectiveness of different programmes of age-targeted community chemotherapy in reducing the amount of morbidity due to helminth infection. The magnitude of age-related heterogeneities is found to be very important in determining the results of age-targeted treatment programmes. The model was verified using field data from control programmes for Ascaris lumbricoides and Trichuris trichiura, and was found to provide accurate predictions of prevalence and mean intensities of infection during and following different control regimes.

Previously we had reported thatNippostrongylus brasiliensis, a helminth with a lung migratory phase, affected host resistance againstMycobacterium tuberculosisinfection through the induction of alternatively activated (M2) macrophages. Several helminth species do not have an obligatory lung migratory phase but establish chronic infections in the host that include potent immune downregulatory effects, in part mediated through induction of a FoxP3+T regulatory cell (Treg) response. Treg cells exhibit duality in their functions in host defense againstM. tuberculosisinfection since their depletion leads to enhanced priming of T cells in the lymph nodes and attendant improved control ofM. tuberculosisinfection, while their presence in the lung granuloma protects against excessive inflammation.Heligmosomoides polygyrusis a strictly murine enteric nematode that induces a strong FoxP3 Treg response in the host. Therefore, in this study we investigated whether host immunity toM. tuberculosisinfection would be modulated in mice with chronicH. polygyrusinfection. We report that neither primary nor memory immunity conferred byMycobacterium bovisBCG vaccination was affected in mice with chronic enteric helminth infection, despite a systemic increase in FoxP3+T regulatory cells. The findings indicate that anti-M. tuberculosisimmunity is not similarly affected by all helminth species and highlight the need to consider this inequality in human coinfection studies.
