  • Rotavirus Vaccine Breakthrough With Vaccine-Modified Disease in a Sibling Cluster of Equine-Like G3P[8] Infection
    Ahmad Syatir Tahar, Eng Joe Ong, Dewi Mamora, Cheng Siang Tan
    Journal of Medical Virology, 2026
    Rotavirus remains one of the major causes of childhood gastroenteritis despite the widespread introduction of rotavirus vaccines. Here, we report a sibling cluster of three children hospitalized with fever, vomiting, and diarrhea. Two unvaccinated siblings (11 years 9 months and 10 years 1 month) developed severe gastroenteritis with profuse watery diarrhea and prolonged hospitalization, while the youngest sibling (3 years 4 months), fully vaccinated with the RotaTeq vaccine, developed milder symptoms and had a shorter duration of hospitalization. Disease severity assessed using the modified Vesikari score indicated severe disease in the unvaccinated siblings (scores 16 and 11) and moderate disease in the vaccinated child (score 10). Rapid antigen testing followed by molecular analysis confirmed equine‐like G3P[8] rotavirus infections in all three patients. Epitope analysis of the VP7 protein identified four nonsynonymous substitutions (T87S, N213T, K238D, and D242A) within antigenic regions compared with the RotaTeq G3 vaccine strain. The reduced disease severity in the vaccinated sibling suggests partial protection conferred by the RotaTeq vaccine despite breakthrough infection and highlights the importance of continued molecular surveillance of circulating rotavirus strains.
  • Leptospira and Leptospirosis: A Review of Species Classifications, Genomes, Morphological Structures, Antimicrobial Resistances, Transmissions, and Clinical Manifestations
    Lesley Maurice Bilung, Ahmad Syatir Tahar, Chai Fung Pui, Muhammad Khairil Syamri Bakeri, Lela Su’ut, Romano Ngui, Rosdi Kira, Kasing Apun
    Current Microbiology, 2026
    Leptospirosis, also known as "rat-urine disease", is a neglected zoonotic and waterborne disease that is caused by Leptospira spp. This disease is transmitted by direct and indirect exposure to the urine and stool of infected animals. The current estimate has highlighted that leptospirosis has caused at least one million cases and 60,000 deaths, with high endemicity in tropical regions. With climate change, urbanisation, and increasing human-animal interaction, the threat of leptospirosis and other zoonotic diseases will continue to emerge. Investing in multidisciplinary research, technology, and global collaboration is critical to anticipate, detect, and respond effectively to these evolving threats.

    Ahmad Syatir Tahar, Sultana Parvin Habeebur-Rahman, Khatijah Yaman, Romano Ngui, Li Li Andrea Lim, Josprin Edwin, Nur Suhada Saboden, Tracy Manggi, Cheng Siang Tan
    Scientific Reports, 2025
    Hookworms are blood-sucking intestinal parasites that can cause anaemia and protein loss in humans. Ancylostoma ceylanicum, a zoonotic hookworm species of dogs, is the second most common cause of human hookworm infections. With the increasing anthelmintic resistance risks and the uncontrolled stray dog population in Sarawak Borneo, East Malaysia, understanding the genetic structure of A. ceylanicum is crucial for tracking mutation patterns and assessing zoonotic transmission risks. This study determined the prevalence and genetic diversity of dog hookworm species using microscopy, PCR and sequencing, revealing A. ceylanicum (43.6%; 89/204), followed by mixed infections of A. ceylanicum and A. braziliense (9.3%; 19/204), single infections of A. caninum (6.3%; 13/204), and A. braziliense (1.4%; 3/204) in stray dogs in East Malaysia (Sarawak Borneo). Phylogenetic analysis of the cytochrome oxidase subunit 1 (COX1) gene showed that A. ceylanicum from Sarawak Borneo clustered across all major clades, indicating high genetic divergence and admixture. Haplotype analysis revealed that the Malaysian A. ceylanicum population highly mirrors those in Cambodia and Thailand, suggesting significant gene flow across Southeast Asia, while regional disparities exist compared to other countries. These findings provide critical epidemiological insights for hookworm control strategies, including stray dog management and potential adjustments to mass drug administration programs. The high genetic connectivity of A. ceylanicum population across borders underscores the need for enhanced surveillance, One Health approaches, and monitoring anthelminthic resistance to mitigate the risk of zoonotic transmission.

    Foods and Raw Materials, 2025
    Over the past decade, the occurrence of milk-borne infections caused by Shiga toxin-producing Escherichia coli (STEC) and Salmonella enterica serovar Typhimurium (S. Typhimurium) has adversely affected consumer health and the milk industry. We aimed to detect and genotype the strains of E. coli and S. Typhimurium isolated from cow and goat milks using two genotyping tools, BOX-PCR and ERIC-PCR. A total of 200 cow and goat milk samples were collected from the dairy farms in Southern Sarawak, Malaysia.First, E. coli and Salmonella spp. detected in the samples were characterized using PCRs to identify pathogenic strains, STEC and S. Typhimurium. Next, the bacterial strains were genotyped using ERIC-PCR and BOX-PCR to determine their genetic relatedness. Out of 200 raw milk samples, 46.5% tested positive for non-STEC, 39.5% showed the presence of S. Typhimurium, and 11% were positive for STEC. The two genotyping tools showed different discrimination indexes, with BOX-PCR exhibiting a higher index mean (0.991) compared to ERIC-PCR (0.937). This suggested that BOX-PCR had better discriminatory power for genotyping the bacteria.Our study provides information on the safety of milk sourced from dairy farms, underscoring the importance of regular inspections and surveillance at the farm level to minimize the risk of E. coli and Salmonella outbreaks from milk consumption.
  • In-vitro susceptibility of pathogenic and intermediate Leptospira species towards antibiotics and herb extracts
    Ulok V.
    Tropical Biomedicine, 2024
    Leptospirosis is a severe and potentially fatal re-emerging zoonotic and waterborne disease caused by pathogenic and intermediate species of Leptospira. Given the high global rates of morbidity and mortality associated with this disease, there is an urgent need to explore alternative therapeutic agents to enhance treatment options. This study investigates the anti-leptospiral efficacy of several common antibiotics-penicillin G, doxycycline, ampicillin, amoxicillin, cefotaxime, chloramphenicol, and erythromycin, as well as extracts from local herbs, Hydnophytum formicarum Jack and Boesenbergia stenophylla, against pathogenic and intermediate Leptospira strains. A broth microdilution method determined the minimum inhibitory concentration (MIC) for the antibiotics and herb extracts. Both herbs were extracted using four different solvents: ethyl acetate, methanol, hexane, and chloroform. The extracts were then analysed using gas chromatography-mass spectrometry (GC-MS) to identify their phytochemical compounds. The results demonstrated that cefotaxime and erythromycin exhibited the highest anti-leptospiral activity, with MIC values of 0.2 µg/mL. This was followed by amoxicillin and ampicillin (0.2-0.39 µg/mL), penicillin G (0.39-3.13 µg/mL), chloramphenicol (0.78-3.13 µg/mL), and doxycycline (0.78-12.5 µg/mL). H. formicarum Jack and B. stenophylla extract extractions displayed the lowest MICs (62.5 µg/mL) for the ethyl acetate, methanol, and hexane extracts. They contained various phytochemical constituents, including some with anti-leptospiral properties. These findings indicate that different strains of Leptospira respond with varying levels of inhibition to the antibiotics and herb extracts studied. The extracts from H. formicarum Jack and B. stenophylla may have potential as anti-leptospiral drugs. However, further in-vivo studies are needed to better understand their efficacy against Leptospira.

    Journal of Medical Virology, 2023
    Rotavirus is the leading causative viral agent of pediatric acute gastroenteritis globally, infecting mostly children 5 years old and below. Data on rotavirus prevalence in Malaysia is scarce, despite the WHO's recommendation for continuous rotavirus surveillance, and has underestimated the need for national rotavirus vaccination. Characteristics of the current rotavirus strains in Malaysia have to be determined to understand the rotavirus epidemiology and vaccine compatibility. This study sought to determine the genetic relatedness of Sarawak rotavirus strains with global strains and to determine the antigenic coverage and epitope compatibility of Rotarix and RotaTeq vaccines with the Sarawak rotavirus strains via in silico analysis. A total of 89 stool samples were collected from pediatric patients (<5 years old) with acute gastroenteritis at private hospitals in Kuching, Sarawak. Rotavirus was detected using reverse transcription‐polymerase chain reaction. Positive amplicons were analyzed using nucleotide sequencing before phylogenetic analyses and assessment of epitope compatibility. Genotyping revealed G1P[8] (1/13; 7.7%), G3P[8] (3/13; 23%), G9P[4] (1/13; 7.7%), and G9P[8] (3/13; 23%), G9P[X] (1/13; 7.7%), GXP[4] (1/13; 7.7%), and GXP[8] (3/13; 23%) in samples. All wild‐type Sarawak rotavirus strains, with the exception of G1, showed variations in their phylogenetic and antigenic epitope characteristics.

    Waterborne parasites, particularly Cryptosporidium and Giardia, are emerging pathogens implicating the safety level of drinking water globally. The aim of this study was to determine the distribution pattern of waterborne parasites in raw and treated water at urban and rural water treatment plants and untreated water from gravity-feed system in Kuching, Sarawak. This study focused on water treatment plants (four urban and two rural) and Bong rural community that utilise gravity-feed system in Kuching, Sarawak. A total of 69 raw and treated water samples were collected and processed before being used in detection of Cryptosporidium and Giardia using Aqua-Glo™ G/C Direct and 4′,6-diamidino-2-phenylindole stains, as well as other parasites that were detected using Lugol’s iodine staining. Parameters which were temperature, pH, turbidity, dissolved oxygen, total dissolved solids, conductivity, faecal coliform of the water as well as rainfall intensity were determined. Correlation of the parameters with distribution of the waterborne parasites was analysed. Out of 69 water samples collected across all localities, 25 samples were contaminated with waterborne parasites with varying waterborne parasite concentration in the water samples. The presence of waterborne parasites in the raw and treated water of water treatment plants in this study signifies public health threats do exist despite being conventionally treated. This study also highlights that the gravity-feed system which is commonly depended by rural communities in Malaysia may facilitate waterborne parasitic infections.
  • Epidemiological study of human intestinal parasites in sarawak, east malaysia: A review
    Tahar A.S.
    Tropical Biomedicine, 2021
    Intestinal parasitic infections are endemic in rural settings and may account for asymptomatic infections to various health complications. These infections are a cause of concern for communities of lower economic status, especially in developing countries. In Sarawak, indigenous populations residing in geographically inaccessible areas are socially and economically disadvantaged. Through close association with nature, these populations are prone to intestinal parasitism. Currently, scattered information has led to a continual state of neglect at each level of parasitic infection control. This urges for a review of their distribution and transmission based on previous reports to understand the pattern of the diseases in the state which can further address the improvement of mass controlling programs. A literature search was conducted to collect previous reports on human intestinal parasites in Sarawak, East Malaysia from PubMed (Medline), SCOPUS, ScienceDirect and Web of Science from January 2019 to March 2021. Extrapolating the current data in Sarawak which is still considered limited, further interdisciplinary strategies are demanded to give insights in the epidemiology and true prevalence of intestinal parasites in Sarawak. This review addresses for redirection of attitude towards intestinal parasitic infections where it should be given with ample attention by rural populations. In tandem to that, improvement of rural livelihood such as standard of living and sanitation in Sarawak should be accredited as part of the efforts to reduce the number of intestinal parasitic infections in the state. As a control measure, mass deworming should be reconsidered especially to the rural populations.

    International Journal of Current Research and Review, 2021
    Background: Contaminated vegetables with intestinal parasites, particularly those eaten raw, represent a proportion of risks for humans acquiring foodborne parasitic diseases worldwide. Unfortunately, the risk is often neglected as limited studies have been reported about the parasitic occurrence from vegetables retailed in Malaysia. Objective: This study was conducted to determine the occurrence of intestinal parasites in fresh retailed vegetables in Kuching and Kota Samarahan, Sarawak. Methods: A total of 108 vegetables (comprising leafy and root-type vegetables) were purchased from three supermarkets and three wet markets in Kuching and Kota Samarahan. The samples were processed with 0.95% sodium chloride solution and underlaid with Sheather’s sucrose solution. Cryptosporidium and Giardia were detected using AquaGloTM G/C antibody reagent and 4′,6-diamidino-2-phenylindole stain. Other parasites were detected using Lugol’s iodine stain. Results: A total of 24 out of 108 vegetables samples (22.2%) were contaminated with nematode larvae (range: 0.01 – 0.71 larvae/g), Cryptosporidium oocysts (range: 0.01 – 0.03 oocysts/g), hookworm ova (range: 0.01 – 0.02 ova/g) and Giardia cyst (0.01 cysts/g). There were no significant differences (p > 0.05) for means of parasite concentrations in vegetables from supermarkets and wet markets, as well as parasite concentrations from leafy-type and root-type vegetables. Conclusion: The findings revealed relatively high numbers of intestinal parasites detected from fresh retailed vegetables, signifying potential foodborne transmission of parasitic infections if the vegetables are not prepared hygienically or cooked well. Besides, a high proportion of such infection risk may be reduced if farmers also take part in proper sanitation practices during vegetable production and transportation.
