  • Wolbachia is an obligatory intracellular endosymbiotic bacterium, present in over 20% of all insects altering insect reproductive capabilities and in a wide range of filarial worms which is essential for worm survival and reproduction. In Egypt, no available data were found about Wolbachia searching for it in either mosquitoes or filarial worms. Thus, we aimed to identify the possible concurrent presence of Wolbachia within different mosquitoes and filarial parasites, in Assiut Governorate, Egypt using multiplex PCR. Initially, 6 pools were detected positive for Wolbachia by single PCR. The simultaneous detection of Wolbachia and filarial parasites (Wuchereria bancrofti, Dirofilaria immitis, and Dirofilaria repens) by multiplex PCR was spotted in 5 out of 6 pools, with an overall estimated rate of infection (ERI) of 0.24%. Unexpectedly, the highest ERI (0.53%) was for Anopheles pharoensis with related Wolbachia and W. bancrofti, followed by Aedes (0.42%) and Culex (0.26%). We also observed that Wolbachia altered Culex spp. as a primary vector for W. bancrofti to be replaced by Anopheles sp. Wolbachia within filaria-infected mosquitoes in our locality gives a hope to use bacteria as a new control trend simultaneously targeting the vector and filarial parasites.

  • Indonesia and South Korea have become inseparable in various respects since the 2 countries established diplomatic relation in 1973. Indonesia is a tropical region that stretches across the equator, comprised of 5 main islands (Java, Kalimantan, Sumatra, Sulawesi, and Papua) and 4 archipelagoes (Riau, Bangka Belitung, Nusa Tenggara, and Maluku). As most population of Eastern Indonesia (Sulawesi, Papua and Nusa Tenggara & Maluku) live in poor areas, it is expected that there will be many parasites. Nevertheless, little is known about the status of parasites in Indonesia. This study examines the prevalences of malaria and lymphatic filaria, which are prevalent in Indonesia, as well as those of soil-transmitted-helminths (STH). As a result, the Plasmodium falciparum and P. vivax case loads are almost equal. The current prevalence of P. vivax is uniformly low (<5%) in all age groups and annual parasite incidence (API) showed decreasing tendency as 0.84 per 1,000 population in 2016. However, more than 65 million people still live in malaria epidemic regions. Lymphatic filariasis remains an important public health problem and 236 cities were classified as endemic areas in 514 cities/districts in 2017. It is difficult to ascertain the current prevalence rate of STH in Indonesia, although West Sumba and Southwest Sumba in East Nusa Tenggara reported prevalence rate of more than 20%. The study also considers the (sero) prevalences of other parasites identified in Indonesia. This report should be useful not only to parasitologists but also to travelers and people with business in Indonesia.

  • Careya arborea Roxb. (Lecythidaceae) is a significant medicinal plant known as kumbhi in Ayurveda. Though, most of the plant parts are used in traditional systems of medicine, bark and leaves constitute the important medicinal parts. The present review gives an account of the updated information on its phytochemical and pharmacological properties. The review reveals that numerous phytochemical constituents have been isolated from the plant possessing hepatoprotective, antioxidant, antimicrobial, anticoagulant, analgesic, antidiarrhoeal and various other important activities. Leaves are used in filaria, colic, loose motions and ulcers. Bark is used as an antipyretic, abortifacient, antipruritic and in smallpox, urinary discharges and rheumatic pain. Since last few decades, extensive exploration has been done to establish the biological activities and pharmacology of the extracts and plentiful chemical constituents including flavonoids, tannins, alkaloids, terpenoids and many other have been isolated.

  • 사람들이 모기를 싫어하는 이유는 많다. 모기는 사람과 가축에 각종 병원체를 옮기며, 또한 많은 스트레스를 주고, 이로 인한 정신적인 피해가 크기 때문이다. 가축에서는 가축이 수면을 제대로 취하지 못하게 하고, 질병을 일으켜서 경제적인 피해를 입히기도 한다. 모기로 인해 육계는 성장이 늦어지고, 산란계에서는 산란율이 떨어진다. 사람이 모기에 물리게 되면 간지럽고, 빨갛게 붓는 피부 알러지가 생기고, 잠잘 때 윙윙 소리를 내어 수면을 방해한다는 점, 그로 인한 불쾌감, 정신적 스트레스 등의 피해를 입는다. 그러나 무엇보다도 모기가 주는 가장 큰 피해는 각종 질병을 옮기고 다닌다는 것이다. 모기로 인해 옮겨지는 병으로는 뇌염(encephalitis), 마랄리아(malaria), 상피병(filaria), 황열병(yellow fever), 뎅기열(dengue fever) 등을 들 수 있다. 그 중에서도 국내에서 발병하는 병은 일본뇌염(Japanese encephalitis), 말라리아, 상피병 등이 알려져 있다. 가축에서 오는 모기 매개 질병은 소의 아까바네병, 유행열, 이바라기병 및 츄잔병, 아이노바이러스 감염증 등이 있고, 돼지에서는 사람에게 뇌염을 일으킬 수 있는 돼지일본뇌염이 있고 닭에서는 닭류코사이토준병이 있다.

  • A case of periocular dirofilariasis has been diagnosed in Iran. A 27-yr old female referred with a history of edema and redness in the left eye since 2 wk ago. On slit lamp examination, a moving thread-like worm was seen in the subconjunctival area. Two days later, a 126 mm long, live filaria worm was extracted from the lower lid subcutaneous tissue. The worm was diagnosed as, likelihood, Dirofilaria immitis on microscopic examinations. The present case suggests that D. immitis can cause periocular infections.

  • The object to this study is to identify the genus and species of the microfilariae which were recently found in the area of Youngju-Gun. THe identification of the microfilariae was made on the morphologicla aspects. 1. Blood samples were collected through vena punction from known microfilariae carriers living in the newly confirmed filaria endemic area of Youngju0Gun in Jyongsang Pukdo Province. Youngju-Gun is located in the mountainous central part of Korean Peninsula. 2. The following fixation and staining techniques were applied. (1) Fixation by drying in the air, followed by staining with Azeo or Giemsa. (2) Knott's fixation method (2% formalin), followed by staining with Azur II. 3. A comparative study of the body length of the microfilariae after different fixation and staining techniques were applied. (1) Knott's fixation method followed by staining with Azur II : average body length found was 28.4$\mu$. (2) Dry fixation followed by staining with Giemsa : average body length found was 209.4$\mu$. (3) Dry fixation followed by staining with Azeo : average body length found was 205.4$\mu$. 4. The locations of the different body cells were measured in 60 individuals of microfilariae in the wet preparation fixed by Knott's method and stained with Azur II. The distance of the different body cells to cephalic apex of microfilariae was measured and calculated as a percentage of the total body length. The average results are as follows : BNC , 3.04% ; N, 22.74%, EP, 31.4% ; EC, 37.77%, G1 cell , 67.94%; G2 cell, 73.54% : G3 cell , 75.55% ; G4 cell, 77.65% ; AP, 82.02%%. 5. As a result of the above findings the microfilariae found in the above mentioned area could be identified as Brugia malai(BRUG, 1927) BUCKLEY, 1960.

  • A survey was under taken of six district of Northern India viz. Bareilly, Pilibhit, Udham Singh Nagar, Nainital, Almora and Rampur. The age, breed, sex and physiological status recorded. A total number of 854 cattle examined out of which lactating (274 cases), non lactating (302 cases) heifers (128 cases), calves (82 cases) and adult male (68 cases) were examined. An incidence of 4.92 percent (42) of microfilarisis was recorded. The highest prevalence was observed in Rudrapur District of Udham Singh Nagar (33.33%, 4/12), followed by Lalkaun in Nanital District (21.74%, 10/46), Rampur (12.50%, 2/16), Bareilly (8.16%, 8/98) and Pilibhit (1.22%, 1/82). No infection was observed in Almora region. Amongst 854 cattle of different group incidence was highest in adult male (12.20%, 10/82), followed by non lactating (3.82%, 12/314) and lactating (2.70%, 2/74), (7.64%, 12/157) was found in Heifers. For haemeto-biochemical, serum minerals estimations and therapeutic study 32 animals suffering from filariasis and 18 healthy animals were taken. 16 animals were treated with ivermectin $@200{\mu}g/kg $ body weight. Effect of this disease on production has also been estimated for which body weight and milk production was observed. The main clinical manifestations observed were anaemia, loss of appetite, debility, oedematous swelling especially in the abdominal region, increased heart rate, and respiration rate. Haematological changes indicated decrease in hemoglobin, total erythrocyte count, packed cell volume, erthrocyte fragility and neutrophil, whereas there was significant increase in erythrocytes sedimentation rate (ESR), total leukocyte count (TLC), lymphocyte and eosinophils. Biochemical changes showed significant reduction in the values of serum albumin, A : G ratio, where as there was significant increase in blood glucose, blood urea nitrogen (BUN), globulin, total lipid, total cholesterol, phospholipids, serum bilirubin. Serum mineral profile also altered markedly, which indicate a significant decrease in Ca, Cu, Fe, Zn, and Mn with increase value of Na and Cl. There was no significant change in P and K values. Enzyme pattern in micro filaria infected animal indicated increased level of AST, ALT, alkaline phosphatase, ornithine carbamyl transferase, sorbitol dehydrogenase, glutamate dehydrogenase, isocitric dehydrogenase and lactate dehydrogenase. In blood gas values and acid/base balance, there was an increase in $PVCo_2$ and $PVo_2$. It has been observed that microfilaria infected cattle showed decrease in body weight and milk production. Animal treated with ivermectin showed the return of these above values toward normalcy.
