Abstract Background Soil-Transmitted Helminths are a group of parasites that cause gastrointestinal infections in humans and require the soil to develop into their infective forms. Ecological factors such as soil temperature, soil pH and rainfall patterns are, however, important determinants for the successful transmission of soil helminths as they play a major role in their abundance and survival in the soil. The study investigated the ecological factors influencing the transmission of soil-transmitted helminths in Ifedore district, Southwest Nigeria. Results Out of the one hundred and ninety-two (192) soil samples from the study area, one hundred and fifty-two 152 (79.2%) were positive for the presence of soil helminths’ larvae and ova. Higher occurrence of soil helminths was recorded during the rainy months (n = 416) than during the months with no records of rainfall (n = 290). Sandy soil had the highest number of soil helminths 285 (40.4%), while clay soil recorded the least 88 (12.5%). Soil temperature showed negative correlations with the occurrence of Ancylostoma duodenale (r =  − 0.53) and Strongyloides stercoralis larvae (r =  − 0.36), while soil conductivity showed positive correlations with the occurrence of Ascaris lumbricoides (r = 0.28) and A. duodenale (r = 0.34). Conclusion It is evident from the study that ecological factors played a significant role in the occurrence and abundance of soil-transmitted helminths. This research is important for predicting and monitoring soil-transmitted helminthiasis in endemic countries, and to devise effective control measures.

Background. Ancylostomiasis is an infection caused by hookworms. It is estimated that hookworms infect 1.2 billion people worldwide and cause higher morbidity than other types, mainly due to iron deficiency anemia. Hookworm infection increases with age. The main clinical manifestations are abdominal pain, features of iron deficiency anemia and hypoproteinemia. Diagnosis is based on the finding of characteristic eggs in the stool. Case presentation. A 67-year-old female patient had been administered into the Internal Medicine Ward of Dr. M. Djamil Padang Hospital with the main complaint of weakness, fatigue, and lethargy which had increased since 3 days before being admitted to the hospital. The patient also had complaints of pale skin, fever, heartburn, decreased appetite and weight loss. The patient was admitted to the hospital with awareness of compost mentis, cooperative, and his general condition appeared to be moderately ill, blood pressure 130/90 mmHg, pulse rate 104 x/minute, regular pulse, adequate filling, respiratory rate 22 x/minute, temperature 37.8 C. On physical examination, the conjunctiva of the pantient’s eyes were anemic. Laboratory examination revealed Hemoglobin 4 g/dl, Hematocrit 16%, MCV/MCH/MCHC 62fl/15pg/25g/dL, Reticulocytes 0.5%, SI/TIBC 22/315 mg/dL, Ferritin 8.5 ng/mL, and peripheral blood smear showing severe hypochromic microcytic anemia and relative eosinofilia. Ancylostoma duodenale worm eggs were found on routine stool examination. Final diagnosis was Severe microcytic hypochromic anemia caused by an iron deficiency and Ancylostomiasis. Severe microcytic hypochromic anemia caused by iron deficiency and ancylostomiasis was established based on the patient’s history, physical examination and laboratory investigations. Conclusions. Hookworms infect many people worldwide and cause high morbidity, mainly due to iron deficiency anemia. The highest prevalence is found in the tropics and subtropics, including Indonesia. The main clinical manifestations are abdominal pain, features of iron deficiency anemia and hypoproteinemia. Diagnosis is based on the finding of characteristic eggs in the stool. Albendazole 400 mg single dose resulted in 80% cure and a dose of 200 mg/day for 3 days gave 100% cure. Treatment of anemia is by administering ferrous sulfate or ferrous gluconate orally 200 mg three times a day and continued for up to 3 months after normal hemoglobin levels are achieved to maintain iron stores.

Penyakit cacingan merupakan masalah kesehatan yang masih banyak ditemukan di dunia, hampir 2 miliar orang terinfeksi Soil Transmitted Helminth (STH). Cacing yang tergolong STH adalah Ascaris lumbricoides, Trichuris trichiura dan cacing tambang (Ancylostoma duodenale dan Necator americanus). Diagnosis penyakit cacingan ditegakkan dengan pemeriksaan mikroskopis tinja yang ditunjang dengan pewarnaan. Eosin dan lugol selama ini digunakan sebagai pewarna pada pemeriksaan mikroskopis tinja. Daun jati (Tectona grandis Linn.f) mengandung senyawa antosianin yang dapat digunakan sebagai pewarna alami. Tujuan penelitian ini untuk mengetahui kemampuan rendaman daun jati dalam mewarnai stadium telur parasit STH jika dibandingkan dengan pewarna eosin 2% dan lugol 2%. Metode pemeriksaan tinja yang digunakan adalah metode sedimentasi. Rendaman daun jati diperoleh dengan cara merendam daun jati dengan Etanol 96% dan HCl pekat selama 24 jam. Hasil pewarnaan menggunakan rendaman daun jati memberikan nilai efektif 100% pada telur Ascaris sp. dan Trichuris sp., dan memberikan nilai efektif 66,7% pada telur Hookworm. Berdasarkan perhitungan uji Chi-square dan tabel Fisher Exact dapat disimpulkan bahwa rendaman daun jati  memiliki kemampuan yang signifikan seperti eosin 2% dan lugol 2% dalam mewarnai stadium telur parasit STH.Kata Kunci : rendaman daun jati, telur STH, pewarna alternatif

Abstract Ascaris lumbricoides, Trichuris trichiura, and Ancylostoma duodenale are soil-transmitted helminths (STHs) and medically neglected in Iraq country in spite of their effect on the public health. A cross-sectional study was performed in the Maternity and Childhood Teaching Hospital and General Education Hospital in Al-Dewanyia province, included 850 tool samples collected from patients who attended to the O&P lab. General stool examination (GSE), Direct wet mount method DWMM and Kato-Katz were using for diagnosis of STH infections through detected the adult and the ovum of the helminthes. A conventional multiplex PCR assay was used for detection of STHs in fecal samples. Base on microscopic examination. The results showed that 275/ 850 range among triple, double and single infection on other hand was 365/ 850 range among triple, double and single infection. In conclusions the investigative sensitivity of DWMM is notable for STH, in exception, it is capable to identify patients with the intention of highest required of management, and therefore contributes to the universal target to reduce STH as a community healthiness trouble.

Hookworm disease is known to be caused allergic manifestation and severe anemic pathogenicity in man and canine hosts. Attempts have been made to establish laboratory models of Necator americaus, Ancylostoma duodenale, and Ancylostoma ceylanicum, together with canine parasite, Ancylostoma caninum. The studies include pathophysiological aspects of the host-parasite relationship, and develop to establish patent infection. Immunological approach to selecting antigen for diagnosis and protective immunity purpose using larval and adult worm antigens and their secretions became the focus with the subsequent discovery of cloning in vaccine development as main research interest. Chemotherapy of newer drug screening in laboratory models ultimately selected to use for preventive chemotherapy in hookworm endemic areas using recommended drugs.
