Dipteran Species

Introduction: Dipteran species (flies) are one of the most important insects within the public health and forensic fields. Previous studies have shown that flies play an important role in transmitting the diseases and also estimating the time of death, but their diversity by new methods has been less studied. Methods: Dipteran specimens were collected from rabbit carcasses during spring and summer 2019 and then identified. We used the three measures of Hill numbers (q=0,1,2) to compare the species diversity between the seasons. The analysis was performed with an R package (iNEXT) that provided in 2014. Results: During the present study, 12 dipteran species were collected on rabbit carcasses. L. cuprina and M. stabulans were recorded only from the remains of rabbits in summer. The analysis with iNEXT software showed that species richness (q = 0) in spring is lower than summer and this difference was significant. While, the value of Shannon and Simpson diversity index (q = 1, 2) in summer was lower than in spring. Shannon index value was not significantly different between the seasons, as its confidence intervals almost completely overlapped, but a significant difference in Simpson index was detected between the seasons. Conclusion: We conclude that Ch. albiceps, L. sericata and C.vicina are more frequent flies in the study area and dipteran species are more diverse in spring. The current study provided a database in the field of public health and forensic entomology that could be useful for estimating minimum postmortem intervals and also in vector control programs.

Rumput laut atau seaweed termasuk tumbuhan berthallus yang banyak dijumpai hampir di seluruh pantai Indonesia, terutama wilayah pantai yang mempunyai rataan terumbu karang.  Perbedaan mendasar sistem hidupnya dengan tumbuhan darat adalah dalam pengambilan zat-zat makanan. Tumbuhan darat sangat bergantung pada akar sebagai alat pengambil/ penyerap zat hara dari substrat, sedangkan rumput laut menyerap zat hara yang dibutuhkan bagi pertumbuhannya dari medium air dengan cara difusi melalui permukaan substansi fisiknya.Penelitian ini bertujuan untuk mengetahui struktur komunitas rumput laut di perairan Pasir Panjang Pulau Limbah, Kecamatan Paguyaman Pantai, Kabupaten Boalemo, Provinsi Gorontalo. Metoda penelitian yang digunakan adalah bersifat diskriptif.Adapun pengumpulan data dilakukan dengan metode sample survey methods. Hasil penelitian menunjukan bahwa perairan Pulau Limbah di dominasi oleh Rumput Laut Coklat dengan kelimpahan tertinggi Padina australis. Nilai Indeks Keanekaragaman (H’) Rumput Laut tertinggi terdapat pada stasiun C dengan nilai rerata: 1,854 dan yang terendah pada Stasiun A dengan nilai rerata: 1,469. Nilai Indeks Keseragaman (E)  nilai tertinggi terdapat pada Stasiun C dengan nilai rerata: 0,679 dan terendah pada stasiun A dengan nilai rerata: 0,668. Nilai indeks Dominansi (C) tertinggi terdapat pada Stasiun A dengan nilai rerata : 0,251 dan nilai terendah stasiun B dengan nilai rerata: 0,187. Analisis Ragam (Anova) menunjukan bahwa stasiun penelitian memberikan perbedaan yang nyata (P≤0,05) terhadap nilai Indeks Keanekaragaman (H’), Indeks Keseragaman (E) serta Indeks Dominasi (C).  Seaweed including thallus plants that are found almost all over the coast of Indonesia, especially on beaches that have coral reefs. Seaweed is a photosynthetic organism as well as plants on land. The fundamental difference of his life system is in the taking of food substances. Ground plants realy heavily on roots as a nutrient removal device from the substrate, while seaweed absorbs the nutrients needed for its growth from the water medium by diffusion through the surface of its physical substance. This study aims to determine the structure of seaweed communities in Limbah Island Waters, District Paguyaman Beach. The results showed that the waters of Limbah Island is dominated by brown seaweed with the highest species abundance was Padina australis. The highest index value of Seaweed diversity (H’) was found at station C with average: 1,854 and the lowest at station A with a mean of: 1,469. For uniformity index value (E) the highest value is at station C with average: 0,679 and the lowest at station A with a mean of: 0,668. The highest index value of dominance (C) is at station A with a mean of: 0,251 and the lowest value at station B with a mean of: 0,187. The result of the analysis of variance (Anova) showed that the research station give a significant difference (P≤0,05) to the Diversity Index (H’), Uniformity Index (E) and Domination Index (C).

Background: Dengue fever in Tigo baleh Bukittinggi community is one of the infectious diseases resulting in serious health problems. Understanding the factors associated with the disease is necessity.Objective: To determine the relationships of the implementation of 3M plus program and the existence of Aedes aegypti larvae towards the number of dengue fever cases in the public health center of Tigo Baleh Bukittinggi, West Sumatera, Indonesia.Methods: This was a case control study conducted between January and December 2016 in the Public Health Center of Tigo Baleh Bukittinggi. There were 78 samples recruited by total sampling, with 39 were assigned in the case and control group. House index (HI) and Container index (CI) were used to measure the presence of Aedes aegypti larvae. The implementation of 3M plus program was measured using questionnaire developed by the researcher. Chi Square was performed for data analysis. Result: Findings showed that house index value was 43.6% and container index was 17.9%. The presence of larvae at home contributes to 24 (61.5%) cases of DHF in the case group and 10 (25.6%) cases in the control group. Poor implementation of the program contributes to 27 (69.2%) cases in the case group and 17 (43.6%) in the control group. Chi square test showed p 0.040 (0.05) for the 3M plus implementation and p 0.03 (0.05) for the presence of Aedes aegypti. Conclusion: There were significant associations between the implementation of 3m plus program and the existence of Aedes aegypti larvae towards the number of dengue fever cases in the public health center of Tigo Baleh Bukittinggi, West Sumatera, Indonesia. It is suggested that the community should do more efforts to prevent the occurrence of DHF through mosquito nest eradication, such as the implementation of 3M Plus and sanitation efforts, and pay attention to any places that potentially become a breeding ground for Aedes aegypti mosquitoes.

Abstract. Keshavarz D, Rassi Y, Oshaghi MA, Azizi K, Rafizadeh S, Shahriarinamadi M. 2020. Dipteran diversity and succession pattern on carcass of rabbits treated with opium: Implication in forensic medicine. Biodiversitas 21: 3135-3141. The present study aimed to investigate the effect of opium on the succession pattern and diversity of Diptera on rabbit carcasses. In the present experimental study, dipteran species were collected from rabbit carcasses during the decay process. During this study, two replicates were performed, and four rabbits were used in each. Rabbits divided equally into two groups. In the first group, animals were received 25 mg opium dross orally via a gastric tube and then gradually increased the dose to 100 mg/case/day, while the second group were used as controls and received distilled water. The most frequent species on both carcass types were Chrysomya albiceps (26.2%), Lucilia sericata (15.9%), and Musca domestica (13.9%). Diversity analysis indicates high species richness on untreated carcasses (Shannon: 2.1; Margalef: 1.7). However, a significant difference was not detected for the Shannon index between the treated and untreated carcasses (P: 0.56). The taxa similarity values for sampling intervals ranged from 0.20-0.46 for both untreated and treated carcasses. Permutation analysis showed that successional patterns of dipteran species were similar between opium dross-treated and untreated carcasses. Therefore, in the case of opioid (opium) abused cadaver, this substance could not have an effect on the PMI estimation based on the pattern of succession. But it seems that the PMI should be corrected when the estimate is based on larval growth rate.

This paper examines the effect of corruption on quality of public health services. Corruption, in Tanzania, is a national concern that upsets public health services. There is a public outcry that corruption is increasing in the public health sector while the government’s effort to combat the phenomenon is unimpressive. This poses worries on the quality of public health services. The current study adopted cross-sectional research design, and a total of 180 respondents were involved in the survey. The Mann Whitney U Test was used to compare differences between perceived quality of health services and respondents’ characteristics. Overall, 87.2% of the respondents perceived low quality of health services, and corruption affected quality of health services to a greater extent. Based on age, employment and wealth status, there was significant difference on reporting perceived quality of health services at 5% and 1% level of significance. In addition, respondents’ sex and employment status showed significant difference in reporting the extent to which corruption affected quality of health services at 5% level of significance. The paper draws out two conclusions: first, the quality of health services was low. Second, corruption exacerbated poor quality of health services. To that effect, interventions to combat corruption in the public health sector are needed so as to improve quality of health services.

After an acute hepatitis E (HEV) outbreak in Southern Switzerland, in January 2017 the local public health authorities started an active program of food chain control and public education. In this retrospective study, we analysed all laboratory-confirmed acute cases of HEV infection diagnosed between 2014 and 2020. In the period before the public health intervention, the number of cases increased steadily from 2014 (4 of 40 tests, 10%) reaching a peak in the last quarter of 2016 (42 of 285 tests, 14.7 %). Afterwards, the number of positive cases decreased steadily, reaching its lowest value (0.3%) in the second quarter of 2019. There was a statistically significant difference between the frequency of positive cases and period of testing, i.e., before and after the introduction of the public health interventions. Our study shows that active public health measures to control sausages containing raw pork liver can reduce the prevalence of HEV infection.

The present work has been done to provide basic data for a better conservation and valorization ofKhaya senegalensis stands in Sudano-Sahelian zone of Cameroon. A 100 m x 50 m transectmethod was undertaken to measure floristic diversity through the use of species richness,Shannon index, Pielou equitability, Simpson index, importance value index and importance valuefamily. The vegetation structure is determined by density, basal area and biovolume. Theinventory included trees with a dbh ?10 cm on an area of 1 ha per plot. A total of 6743individuals distributed in 24 families, 33 genera and 54 species were inventoried in all Khayasenegalensis stands studied. Statistical analysis showed significant differences, Shannon index,Simpson index, Pielou equitability, density, basal area, biovolume, species richness, heights class,diameters class, circumferences class but does not certify a significant difference of importancevalue index among in the villages. The undergrowth of Khaya senegalensis stands is more diverseat Bamé with a Shannon diversity index (ISH=5.87 ± 0.12 bit). The greatest of Pielou equitabilityis observed at Bamé (EQ=0.80 ± 0.01). The largest of Simpson index is recorded at Bamé(D=0.098 ± 0.001). Khaya senegalensis Stands are denser at Bamé (194 ± 3.12 individuals/ha).The basal area and biovolume of Khaya senegalensis stands are very high at Bamé (BA=25.87 ±0.06 m2/ha and Biovolume =15.32 ± 0.012 m3/ha). The species importance value is maximal in allthe studied villages (SIV=300 ± 71.45). The importance value index of species revealed a cleardominance in the undergrowth of Khaya senegalensis stands are Combretum adenogonium;Acacia senegal; Terminalia laxiflora; Guiera senegalensis; Acacia nilotica; Entada Africana.The vertical structure has three aspects, like the L (Dbh), asymmetric (height) and dissymmetrical(circumference) structures attesting to a strong regeneration of the understory ligneous woods ofKhaya senegalensis stands studied.

A cross - sectional study was conducted from November, 2011 to April, 2012 on bovine cysticercosis in cattle slaughtered at Haramaya Municipal Abattoir with the objectives of determining the prevalence of bovine cysticercosis and to characterize the viabilit y of the cyst. Out of 384 systematically selected slaughtered cattle, 28 (7.27%) were infected with Cysticercusbovis. A total of 126 cysts were collected in which 76 (60.32%) were viable while others 50 (39.68%) were degenerated. The anatomical distributio n of cysticerci was liver, heart, shoulder muscle, tongue, masseter and lung in decreasing order of cyst harboring. A statistical analysis of infection rate on the basis of origin of the animal and sex has no significant difference (p> 0.05) but age has si gnificant difference (p<0.05). In conclusion, the present study imply that the disease deserves due attention to safeguard the public health and promote beef industry in the country. Therefore, appropriate control and preventive measures should be taken in order to reduce the disease problem on public health even if its economic significance associated with cysticercosis is minimal.
