Systematic Review and Meta-Analysis: Epidemiology of Human Blastocystis spp. Infection in Malaysia

Blastocystis spp. is a unicellular enteric protozoan parasite in humans with a controversial role in disease etiology. It is common in developing countries among immunocompromised patients and people who have close contact with animals. In this study, we have systematically reviewed previous studies on the distribution and genotypes of human Blastocystis infection in Peninsular Malaysia. Studies examining the prevalence of Blastocystis in diverse demographics, including rural, urban, comorbid conditions, and high-risk populations, were taken into consideration. The infection has been reported in nine states; the total percentage of infection was 17.8% (1671/9397), with the most cases in Pahang (27.3%) and the least in Johor (3.4%). Molecular studies revealed the presence of six subtypes: ST1, ST2, ST3, ST4, ST5, and ST6. ST3 was reported as the predominant subtype in all the states, with a prevalence of 54.7% (338/618). The findings provide greater clarity on the epidemiology of Blastocystis in Malaysia, which will help in policy making towards planning and strategizing control measures against the parasite.

The paper presents the studies on morphological changes in cattle with a different number of fascioles in liver (up to 70 fascioles and up to 250 specimen). A total of 127 heads of 2-4-year-old cattle from the farms of the Republic of Bashkortostan were examined. The diagnosis of fasciolosis was based on epizootological data, clinical indicators, and detection of fasciola eggs in faeces by successive washes of faeces. After slaughter 3 groups of 5 animals were selected based on pathoanatomic, helminthological diagnosis and fasciola invasion intensity. The first group included parasite-free animals, the second group -cattle with an infestation rate of 70 worms/head, the third group -animals with infestation rate of 250 parasites/head. Histological studies were conducted on liver samples in 10% neutral formalin with embedding them in paraffin blocks. After dewaxing 5-7 micrometres thick sections were stained with hematoxylin and eosin and coloured according to Van Gieson's method for connective tissue examination. Morphometric indicators were studied with an ocular ruler. The data was processed on the Pentium OS with Microsoft Word and Excel software and the Student's t-test results validation. The infected bull calves have an enlarged liver size, dense liver texture and tuberous surface, the thickened capsule, thick, sinuous, expanded yellow-white bile ducts cords. Histological and morphometric methods identified structural changes in hepatocytes, hepatic lobules and the microcirculatory system of the liver. Pathological changes in the liver depend significantly on the average number of parasites found on a single infested animal. The work provides a fasciolosis prevention and treatment recommendation, taking into account the manifested pathological liver processes.

“…In 2002, the National Institute of Parasitic Diseases (NIPD), Chinese Academy of Preventive Medicine, renamed the National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention, accompanying a reform from a research institute to a national institute responsible for providing technical support and guidance for national parasitic disease control and elimination through organizing national surveillance, data collection and analysis, response to parasitic disease outbreaks, etc. Construction of the infectious disease and vector surveillance network was initiated in 2005, including surveillance on schistosomiasis, malaria, soiland food-borne parasitic diseases, and other related diseases (Chen et al, 2020). In response to changes in the strategies used for preventing and controlling each disease, our institute has organized and updated the surveillance programs in a timely manner, with adjustment or expansion of content and scope of surveillance (Xu et al, 2015).…”

Parasitic diseases have been widely epidemic in China with a long history. Great endeavours made in past 70 years led to significant decrease in morbidity and mortablity caused by several major parasitic diseases, while challenges existed to eliminate parasitic diseases. Surveillance-response system has play a crucial role in identifying public health problems, ascertaining the distribution and epidemic dynamics, discovering outbreaks and epidemic anomalies, evaluating the effects of on-site intervention activities and identifying risk factors. In this article, we reviewed the progress of the surveillance system for parasitic diseases, analysed the role of NIPD in the construction and application of surveillance-response system of parasitic diseases through elaborating the surveillance activities and typical surveillance-response events led by NIPD. Suggestion and comments for improve the surveillance-response system were put forward for further control or elimination of parasitic diseases.
