“…This study showed that ST3 was the predominant subtype in boys and girls, followed by ST1 and ST2. This result was similar to that of previous studies in Thailand [35,36] and others in different countries, such as Malaysia [37], Turkey [38], Peru [39], and Italy [40]. Our finding showed 18S alleles of Blastocystis in each ST, which include allele 4 (ST1), allele 9 (ST2), and alleles 34 and 37 (ST3).…”

Blastocystis is one of the most common enteric protozoa that inhabits the intestinal tract of humans and different animals. Moreover, it has a worldwide geographic distribution. Its main mode of transmission is via the fecal-oral route. At present, 26 subtypes are widely distributed across both humans and animals. The current study aimed to determine the prevalence and subtype distribution of Blastocystis among school-aged children living on the Thai-Myanmar border, Ratchaburi province, Thailand. In total, 508 samples were collected from children at six schools. The prevalence of Blastocystis infection was amplified and sequenced in the 600 bp barcode region of the small-subunit ribosomal RNA (SSU rRNA). The overall prevalence of Blastocystis infection was 3.35% (17/508). ST3 (11/17) was the most predominant subtype, followed by ST1 (5/17) and ST2 (1/17). A phylogenetic tree was constructed based on the Tamura92+G+I model using the maximum-likelihood algorithm. Surprisingly, all sequences of the ST3-positive samples were closely correlated with the cattle-derived sequence. Meanwhile, all sequences of the Blastocystis ST1-positive samples were closely correlated with the human-derived sequence. Nevertheless, further studies should be conducted to validate the zoonotic transmission of Blastocystis. Based on our findings, personal hygiene and sanitation should be improved to promote better health in children in this area.

“…The prevalence of Blastocytis ranged from 1.1% to 83.7% in these areas. Eight of the 26 studies provided molecular characterization of Blastocystis subtypes using small subunit ribosomal (SSU rRNA) gene sequencing [ 15 , 35 , 42 , 44 , 45 , 61 , 62 , 63 ]. The remaining 17 studies used direct fecal microscopy as their gold-standard diagnostic method [ 35 , 38 , 41 , 43 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ].…”

“…Only one study reported the prevalence of Blastocystis across various states in Malaysia [ 35 ]. The rest of the studies were conducted in specific locations in different states; ten were performed in Selangor [ 15 , 35 , 41 , 52 , 56 , 57 , 58 , 60 , 61 , 62 , 63 ], seven in Pahang [ 35 , 42 , 43 , 44 , 45 , 46 , 51 , 53 , 54 , 55 ], three in Perak [ 35 , 47 , 48 , 49 ], and one each in Kelantan [ 59 ], Terengganu, [ 50 ], and Negeri Sembilan [ 38 ].…”

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.

“…Now, food safety is regarded as a top priority among consumers. Previous literature (e.g., Kuo and Weng, 2021;Sayuti et al, 2020) highlighted food safety is in jeopardy due to crosscontamination and food mishandling that causing exposure of microbial contamination through the food handlers' hands, mouths, and skins (Bou-Mitri et al, 2018;Griffith et al, 2017;Sahimin et al, 2020). In line with this, Sayuti et al (2020) and Valero et al (2016) emphasised the importance of installing good hygiene practices and handling to ensure food safety.…”

This study aims to empirically examine the migrant food handlers’ perceived knowledge, skills, and attitudes and their impact on food quality and safety in the context of Malaysia’s foodservice industry. Using the data gathered from 198 supervisors and managers from food premises in Malaysia and analysis using SPSS (version 20) and SmartPLS 3.0 software, this research found that migrant food handlers have moderate perceived knowledge, skills and attitudes in food handling practices impact the food quality and safety. Specifically, this study confirmed that knowledge and attitudes positively and significantly affect food quality and food safety. However, insignificant results were found between skills and food safety, even though it showed a substantial impact on food quality. The findings are original and unique. It is one of the first studies to investigate the knowledge, skills, and attitude of migrant food handlers their effect on food quality and food safety, especially in Malaysia. Besides, this study extends the established theories from the literature on knowledge, skills and attitudes analysing in the foodservice sector. Therefore, this research finding is valuable for food services practitioners to focus on enhancing food quality and safety through the migrant workforce.
