Amoeba that infects primates can also be found in humans and can be zoonotic. This study aims to identify the distribution of intestinal amoeba in the wild Long-Tailed Macaque (LTM) group located at Cot Murong, Kebun Mangga, and Tugu Zero Kilometer Monument (IZKM) in Sabang City, Aceh Province, Indonesia. A total of 177 stool samples from 59 tails from the three LTM groups were examined microscopically. The results of the examination confirmed seven species of intestinal amoeba, three of which belonged to the genus Entamoeba, namely the Entamoeba histolytica/dispar/moshkovskii complex, Entamoeba coli, Entamoeba pölecki, and four other species from different genera, namely Iodamoeba butschlii, Blastocystis sp., Endolimax nana and Dientamoeba fragilis. The prevalence of intestinal amoeba in wild LTM in Sabang City was 57.6% (102/177). Dientamoeba fragilis was only found in the LTM group of Kebun Mangga. Entamoeba coli dominated the highest prevalence in all LTM groups. The LTM group located around Cot Murong and IZKM had a higher concentration of infection with intestinal amoeba than the Kebun Mangga location. The statistical tests showed a significant difference between the proportions of Iodamoeba butschlii, Endolimax nana and Dientamoeba fragilis, both found in the LTM Cot Murong, Kebun Mangga, or IZKM groups. This study is the first to report amoebic infection prevalence in the wild LTM group in Sabang City, Aceh Province. The pathogenic amoeba that cannot be distinguished microscopically from morphologically identical amoebae needs to be identified molecularly to identify variants and their potential as zoonotic agents. HIGHLIGHTS Intestinal amoeba species found in fecal samples of the wild long-tailed macaques group of Sabang City, Aceh Province, Indonesia, can also be found in human stool samples As many as three of the seven identified amoeba species, namely Entamoeba histolytica, Dientamoeba fragilis, and Blastocystis sp. is a pathogen that can cause diarrhea and colitis in humans and non-human primates The prevalence of amoeba infection in wild macaques in Sabang City is in the high category and tends to increase the incidence of infection in the macaque group, which has more susceptible individuals, namely infants, children, and females GRAPHICAL ABSTRACT

Recently, a putative alcohol dehydrogenase 3, termed EhADH3B of the Entamoeba histolytica isolate HM-1:IMSS was identified, which is expressed at higher levels in non-pathogenic than in pathogenic amoebae and whose overexpression reduces the virulence of pathogenic amoebae. In an in silico analysis performed in this study, we assigned EhADH3B to a four-member ADH3 family, with ehadh3b present as a duplicate (ehadh3ba/ehadh3bb). In long-term laboratory cultures a mutation was identified at position 496 of ehadh3ba, which codes for a stop codon, which was not the case for amoebae isolated from human stool samples. When using transfectants that overexpress or silence ehadh3bb, we found no or little effect on growth, size, erythrophagocytosis, motility, hemolytic or cysteine peptidase activity. Biochemical characterization of the recombinant EhADH3Bb revealed that this protein forms a dimer containing Ni2+ or Zn2+ as a co-factor and that the enzyme converts acetaldehyde and formaldehyde in the presence of NADPH. A catalytic activity based on alcohols as substrates was not detected. Based on the results, we postulate that EhADH3Bb can reduce free acetaldehyde released by hydrolysis from bifunctional acetaldehyde/alcohol dehydrogenase-bound thiohemiacetal and that it is involved in detoxification of toxic aldehydes produced by the host or the gut microbiota.

Introduction: Entamoeba histolytica infections were investigated in residents of the Ariquemes and Monte Negro municipalities in Rondônia State, Brazil. Methods: Stool samples of 216 individuals were processed by the spontaneous sedimentation method and analyzed by microscopy for detection of the E. histolytica/E. dispar complex, followed by the immunoassay method using an enzyme-linked immunosorbent assay-based kit for the E. histolytica stool antigen. Results: E. histolytica/E. dispar cysts were present in 61% (50/82) and 44% (59/134) of the samples from Ariquemes and Monte Negro respectively, with a significant difference in the occurrence of infection between the two populations [p < 0.05; χ2 = 5.2; odds ratio = 2.0 (1.1 - 3.6)]. The E. histolytica antigen detection rate was 36.6% (30/82) for stool samples from Ariquemes, and 19.4% (26/134) for stool taken from the residents of Monte Negro. The rate of the occurrence of amoebiasis was significantly higher in the population from Ariquemes [p < 0.05; χ2 = 7.8; odds ratio = 2.4 (1.2 - 4.7)]. Discussion: Due to the high occurrence of E. histolytica infected residents diagnosed in the region and the unavailability in local clinics of a test to distinguish between the two Entamoeba species, physicians should consider treating E. histolytica/E.dispar infections. Conclusion: The results indicate that E. histolytica infection is highly endemic in the studied areas.

Amoebiasis is one of the major causes of morbidity and mortality worldwide, especially in developing countries because of lack of safe portable water and low level of hygiene. In Nigeria, amoebiasis is prevalent and widespread. The aim of our study was to estimate the prevalence ratio of E. histolytica among infants aged 1 to 59 months admitted at the University of Abuja Teaching Hospital, Gwagwalada, Abuja. The distribution of the infection was reported to relate more with inadequate environmental sanitation, poor personal hygiene and climate. The epidemiology, clinical features and causative agents of diarrhoea were investigated in 100 children aged 1-59 months visiting the University of Abuja Teaching Hospital. One hundred stool samples were collected and examined. The use of direct smear and floatation methods were employed to analyze the prevalence of Entamoeba histolytica in diarrhoeal illness across gender, age, weight and stool appearance of the patients. Out of the one hundred stool samples screened 12% were positive for the parasite. Females were more infected (12.5%) than the males (11.4%), but there was no significant association between prevalence and gender (P>0.05). Children within the age group of 1 to 12 months old had the highest prevalence rate (20.0%). There was a significant difference in the prevalence of Entamoeba histolytica among the age groups (p< 0.05). Children that weighed less than 15kg had the highest prevalence of Entamoeba histolytica (25.0%). There was a positive correlation between the prevalence and weight (p<0.05). Prevalence rate of 16.0% was recorded for watery and bloody stool. There was a positive correlation between the prevalence of Entamoeba histolytica and stool characteristics (p < 0.05). Hence this study analyzes the pattern, morbidty, occurrence and the preventibve measures to enact in tackling diarrhoeal illnesses. This study also aims to enlighten the public especially nursing mothers on the need to maintain proper hygiene in other to prevent contamination of diarrhoeal illness. Entamoeba histolytica can be a re-emerging serious infection when it finds favorable environmental conditions and host factors which are mainly attributed to poor hygiene in this study. This may occur in any area of the world with the same risk factors. Owing to the findings of this research, public health interventions such as the provision of clean water, community health education, observation of food hygiene, and maintenance of functioning sanitation systems are recommended towards controlling the infection.

Gairdia lamblia is one of parasites that cause intestinal problems within the human body, particularly private travelers and children. In this study a total of (100) diarrheal patients, 20 patients with Giardiasis were identified by fecal antigen. 9 out of 20(20%) of them were infected by fecal antigen, while 9(9%) of them were infected by using the screening general stool examination (GSE). The stool samples were collected from patient how vested the Medical City/ Baghdad and Tikrit teaching Hospital during the period from 1 st may 2018 to 1 February 2019. The results revealing a significant difference (p andlt; 0.05) between the two methods of detection for G. lamblia (Fecal antigen method and GSE). IT has been shown that out of 20 infected individuals 12(12%) were males and 8(8%) were females, indicating regarding no significant deference in the distribution of Giardiasis among genders. In regard the age, our results showed that highest infection rate 8(3.2%) was recorded in the age group (10-19) years, followed by the age group (20-2) years which was 692.4%). In this study five mutations were recorded at position (926, 1094, 1202and 1304), by using tpiA gene sequence method, and tpiB gene was on point mutation change (G254A), in the position (85) of triose phosphate isomease.

Commit Suicide

The abuse of some pesticides especially to suicide is one of the current problems of pesticides. Aluminum phosphide induced poisoning usually happens to suicide and sometimes it is due to accidental occupational exposure and in a few cases it has some criminal intensions. This study is conducted to evaluate patients poisoned with aluminum phosphide. In the present study the medical records of cases of poisoning with rice tablets (aluminum phosphide) hospitalized in Ahvaz Razi hospital is studied. Accordingly, a checklist is prepared that included demographic information of patients (age, gender) and information on patient records (information on poisoning) are completed using the patients’ medical records. The analysis of data is done by SPSS V22. 18 patients poisoned with rice tablet (aluminum phosphide) are studied. Results of the study show that 11 patients are male and seven are female. The mean patient age is 27.06 ±8.04 years that is 28 ±9 and 25 ±6.02 in men and women respectively. Statistical tests show no statistically significant difference in mean age in both genders (P> 0.05). Among patients, 11 subjects took aluminum phosphide to attempt suicide and 3 cases took it unintentionally and of course the reason is not mentioned in four cases. Among the patients who tried to commit suicide by taking aluminum phosphide, 6 cases are male and 5 cases are female that no statistically significant difference is observed between the genders in this respect (P> 0.05). In addition to the study of the complications caused by this poisoning and its mortality, it is recommended to responsible authorities to provide the necessary educations and treatments to prevent this type of poisoning.
