  • In a cross-sectional abattoir survey of bovine pulmonary diseases in Mymensingh, during September 2001 to April 2002, subclinical Dictyocaulus viviparous infection was found in mesoendemic level in Bangladeshi adult zebu cattle. The number of mature lung worms varied from $1{\sim}18$ in individual lungs. One to five mature lung worms were most frequent (74.2%) followed by 6 to 10(19.3%) and $11{\sim}18$ (6.5%). Of the total 123 mature worms collected from 31 lungs, there were 50 (40.7%) male and 73 (59.3%) female worms. The female lungworms (mean length 14.41mm) were significantly (P<0.01) larger than the male lungworms (mean length 11.28mm). The number of hydatid cysts varied from $1{\sim}80$ in individual lungs. One to five ($1{\sim}5$) cysts were recorded most commonly (76.0%) followed by $11{\sim}80$ (20.0%) and $6{\sim}10$ (4%). The size (diameter) of the hydatid cysts ranged from $2{\sim}12cm$. Of the total 203 hydatid cysts collected from 31 lungs 45 (22.2%) cysts were fertile and 158 (77.8%) cyst were sterile.

  • Epidemiological study on strongyloidiasis in humans is currently lacking in Malaysia. Thus, a cross-sectional study was carried out to determine the prevalence of Strongyloides stercoralis infection among the inhabitants of longhouse indigenous communities in Sarawak. A single stool and blood sample were collected from each participant and subjected to microscopy, serological and molecular techniques. Five species of intestinal parasites were identified by stool microscopy. None of the stool samples were positive for S. stercoralis. However, 11% of 236 serum samples were seropositive for strongyloidiasis. Further confirmation using molecular technique on stool samples of the seropositive individuals successfully amplified 5 samples, suggesting current active infections. The prevalence was significantly higher in adult males and tended to increase with age. S. stercoralis should no longer be neglected in any intestinal parasitic survey. Combination of more than 1 diagnostic technique is necessary to increase the likelihood of estimating the 'true' prevalence of S. stercoralis.

  • A global increase in fish consumption has led to a rapid expansion of aquaculture production, which has been linked to enhancing the spread of infectious diseases. Viral diseases can cause high mortality in many cultured fish species, posing a serious threat to the aquaculture industry. Infectious hematopoietic necrosis virus (IHNV) is one of the primary threats to aquacultured salmonid species, causing huge economic losses. Since the first report in cultured sockeye salmon Oncorhynchus nerka during the 1950s in North America, IHNV has spread to other regions, including Europe, Asia, South America, and Africa by transportation of infected fish and eggs, causing disease and increasing mortality in a wide variety of salmonid species. Here, we review existing information relevant to IHNV: its phylogenetic characteristics, origin, infection history, virulence determinants, susceptible hosts, vectors, and vaccine development. This review also addresses a possible cross-species transmission of IHNV to a new host, olive flounder Paralichthys olivaceus, a cultured fish of economic importance in East Asian countries.

  • Human gnathostomiasis is a parasitic disease caused by Gnathostoma nematode infection. A rapid, reliable, and practical immunoassay, named dot immuno-gold filtration assay (DIGFA), was developed to supporting clinical diagnosis of gnathostomiasis. The practical tool detected anti-Gnathostoma-specific IgG4 in human serum using crude extract of third-stage larvae as antigen. The result of the test was shown by anti-human IgG4 monoclonal antibody conjugated colloidal gold. The sensitivity and specificity of the test were both 100% for detection in human sera from patients with gnathostomiasis (13/13) and from healthy negative controls (50/50), respectively. Cross-reactivity with heterogonous serum samples from patients with other helminthiases ranged from 0 (trichinosis, paragonimiasis, clonorchiasis, schistosomiasis, and cysticercosis) to 25.0% (sparganosis), with an average of 6.3% (7/112). Moreover, specific IgG4 antibodies diminished at 6 months after treatment. This study showed that DIGFA for the detection of specific IgG4 in human sera could be a promising tool for the diagnosis of gnathostomiasis and useful for evaluating therapeutic effects.

  • Several factors presumed to facilitate the transmission of Taenia spp. were reported in Vietnam. We conducted a cross-sectional study taking questionnaires from 1,185 participants, and collecting 1,151 sera and 1,036 stool samples in northern Vietnam. Sera were examined for circulating antigens of Taenia solium cysticerci using ELISA, stools for Taenia eggs by Kato-Katz smear, and copro-antigens by ELISA. Ag-ELISA revealed 4.6% antigen positivity, indicating infection with viable cysticerci. Taenia eggs were detected in 1.5% of participants. Copro-antigens were found in 2.8% of participants. Eating raw meat and/or vegetables was significantly associated with the presence of copro-antigen (OR=8.6, 95% CI: 1.16-63.9, P=0.01). Considering the high taeniasis prevalence and the associated threat, public health attention should be given to treat the tapeworm carriers in the projected areas.

  • This study was performed to investigate the contamination status of microorganisms that cause food poisoning in shellfish distributed in the metropolitan area of South Korea. The analyses were conducted according to the sample type, season, and region. In particular, the genotype of food poisoning viruses that explosively cause collective food poisoning was analyzed. Total 483 each of four types of shellfish (Crassostrea gigas, Mytilus coruscus, Pectea albicans albicans, and Scapharca subcrenata) were collected from four distribution sites located in the metropolitan area. We investigated foodborne pathogen by multiplex PCR and RT/Nested PCR from shellfish. As a result, Vibrio parahaemolyticus and Bacillus cereus were detected in 13 and 21 samples and Norovirus (NoV) GI and GII were detected in 7 and 12 samples, respectively. V. parahaemolyticus and NoV GI and GII showed differences in types of shellfish and seasons, and no correlation was confirmed with regional differences. Also, as a result of genotyping for the detected NoV GI and GII, they were confirmed as NoV GI.7, GI.5 and GII.3, which are causes of collective food poisoning. Therefore, cross-infection with shellfish can cause food poisoning. In particular, attention must be paid to the handling and cooking of shellfish in organizations that implement group feeding, and it is necessary to establish a management system for microorganisms that cause food poisoning in the process of shellfish farming and distribution.

  • Purpose: This study aimed to examine the association of COVID-19 vaccine attitudes and cognitions of COVID-19-related stigma with vaccine hesitancy among college students. Methods: This cross-sectional study using a web-based survey was conducted with 242 college students in April 2021 before Korea's national COVID-19 vaccination program had begun. Data were analyzed using multinominal logistic regression analyses. Results: Of the participants who were unsure of their intention to receive the COVID-19 vaccine, 66.0% had less experience with flu vaccinations and were 1.43 times more likely to report a mistrust of vaccine benefits (OR=1.43, CI=1.22, 1.68). Those with no intention of receiving the vaccine were 25.0% less likely to be aware of COVID-19 stigma (OR=0.75, CI=0.65, 0.86), 2.08 times more likely to mistrust vaccine benefits (OR=2.08, CI=1.62, 2.68), and 1.53 times more likely to worry about an unforeseen future negative side effects from vaccination (OR=1.53. CI=1.16, 2.00). Conclusion: Nurses could play an important role in educating college students about vaccination benefits, including reviewing vaccines' side effects with evidence, to reduce vaccine hesitancy. College students who have less empathy for others regarding COVID-19 infection might have higher COVID-19 vaccine hesitancy. Accordingly, explaining to students the necessity of their vaccination in preventing transmission to the surrounding community and vulnerable populations is critical.
