Abstract
PURPOSE To describe the role of SWI compared with other MR imaging sequences and CT in diagnosis of cerebral gnathostomiasis. MATERIALS AND METHODS CTs and MRIs of patients with cerebral gnathostomiasis were retrospectively reviewed. The types of intracranial hemorrhage, including intraparenchymal hemorrhage (IPH), subdural hemorrhage (SDH), subarachnoid hemorrhage (SAH), and their locations were recorded. RESULTS Four patients proven as cerebral gnathostomiasis were included. Intracranial hemorrhage was detected in all patients. There was IPH in all patients, SAH in 2 patients, and SDH in 2 patients. All patients (4/4) revealed hemorrhagic tracts which were very conspicuously seen on SWI. Other imaging sequences could also reveal hemorrhagic tracts in 3 patients (3/4) but are less conspicuously seen than SWI. None of the CT brains could detect hemorrhagic tracts. CONCLUSIONS Intracranial hemorrhage associated with hemorrhagic tract, best demonstrated by SWI, is the key imaging characteristic in diagnosis of cerebral gnathostomiasis.

Abstract
Fish and aquatic-derived zoonotic diseases have caused considerable problems in the aquaculture industry and fishery worldwide. In particular, zoonotic diseases can pose widespread threats to humans. With the world’s growing population and potential global trade of aquaculture and fish, the risk of environmental contamination and development of fish and aquatic-derived zoonoses in humans are increasing. The important causes of zoonoses include bacteria, parasites, viruses, and fungi. The zoonotic bacterial agents are divided into two main groups: Gram-positive (Mycobacteriaceae, Streptococcaceae, Erysipelothricaceae families) and Gram-negative (Aeromonadaceae, Vibrionaceae, Pseudomondaceae, Enterobacteriaceae, and Hafniaceae families). The premier parasitic agents include cestodes (tapeworm; e.g. Diphyllobothrium spp.), trematodes (fluke; e.g. Opisthorchis spp.), and nematodes (round worm; e.g. Anisakis spp.). In addition, protozoan organisms such as Cryptosporidium spp. are also considered fish-derived zoonotic pathogens. Two groups of fish-associated fungi causing basidiobolomycosis and sporotrichosis also pose a zoonotic risk for humans. The majority of the fish-derived zoonotic diseases are transmitted to humans mainly via the consumption of improperly cooked or raw fish or fish products. Therefore, the incidence of zoonotic diseases can be reduced by properly processing fish and fish products, e.g. by thermal (heat/freezing) treatment. The prevalence of zoonotic agents in fishes varies seasonally and should be regularly monitored to evaluate the prevalence of pathogens in both wild and cultured fish populations. This review focuses on the fish zoonotic agents/diseases and their control and prevention.

Abstract
BACKGROUND Human gnathostomiasis is a food-borne zoonosis. Its etiological agents are the third-stage larvae of Gnathostoma spp. Human gnathostomiasis is often reported in developing countries, but it is also an emerging disease in developed countries in non-endemic areas. The recent surge in cases of human gnathostomiasis is mainly due to the increasing consumption of raw freshwater fish, amphibians, and reptiles. METHODS This article reviews the literature on Gnathostoma spp. and the disease that these parasites cause in humans. We review the literature on the life cycle and pathogenesis of these parasites, the clinical features, epidemiology, diagnosis, treatment, control, and new molecular findings on human gnathostomiasis, and social-ecological factors related to the transmission of this disease. CONCLUSIONS The information presented provides an impetus for studying the parasite biology and host immunity. It is urgently needed to develop a quick and sensitive diagnosis and to develop an effective regimen for the management and control of human gnathostomiasis.

Effects of Gnathostoma spinigerum infective stage larva excretory-secretory products on NK cells in peripheral blood mononuclear cell culture: focused on expressions of IFN-γ and killer cell lectin-like receptors. Parasitol Res 2020; 119:1011-1021.

Abstract
Human gnathostomiasis is mainly caused by third-stage larvae of Gnathostoma spinigerum (G. spinigerum L3). Excretory-secretory products (ES) released from infective helminthic larvae are associated with larval migration and host immunity modulation. Natural killer (NK) cells have important immune functions against helminth infection. Currently, the effects of ES from G. spinigerum L3 (G. spinigerum ES) on NK cell activity are unclear. This study investigated whether G. spinigerum ES affected human NK cells. Human normal peripheral blood mononuclear cell (PBMC) cultures were used to mimic immune cells within the circulation. PBMC were co-cultured with G. spinigerum ES (0.01-0.05 μg/ml) for 5 or 7 days. Levels of IFN-γ in cultured supernatants were measured by enzyme-linked immunosorbent assay. The expressions of mRNA encoding NK cell receptors, especially the C type killer cell lectin-like family (KLR; NKG2A, NKG2C, and NKG2D) and IFN-γ in ES induced PBMC were determined by quantitative reverse transcription-polymerase chain reaction (RT-qPCR). ES induced PBMC markedly decreased the levels of IFN-γ and increased the expressions of NKG2A and NKG2D on NK cells. In conclusion, low amounts of G. spinigerum ES modulated NK cells by downregulating the transcription of IFN-γ and upregulating the expressions of KLR (NKG2A and NKG2D receptors) during the 7-day observation period. These findings indicate more in-depth studies of NK cell function are required to better understand the mechanism involved in immune evasive strategies of human gnathostomiasis.

Abstract
Along with globalization of traveling and trading, fish-borne nematodiases seems to be increasing in number. However, apart from occasional and sporadic case reports or mini-reviews of particular diseases in particular countries, an overview of fish-borne nematodiasis among travelers have never been performed. In this review, we gathered fishborne nematodiasis among travelers for recent 25 years by an extensive global literature survey using appropriate keywords, e.g. travelers diseases, human infection, anisakiasis, gnathostomiasis, capillariasis, sushi, sashimi, ceviche, Gnathostoma, Pseudoterranova, Anisakis, Capillaria, etc., as well as various combinations of these key words. The Internet search engines PubMed, Medline, Google and Googler Scholar were used as much as possible, and the references of every paper were checked in order to identify useful and reliable publications. The results showed unexpectedly high incidence of gnathostomiasis and low incidence of anisakidosis. The different incidence values of the infection with several fish-borne zoonotic nematode species are discussed, as well as some epidemiological aspects of the infections. The difficulties of differential diagnosis in non-endemic countries are emphasized. It is concluded that travelers must avoid risky behaviors which can lead to infection and that physicians and health authorities must advice travelers on the risks of eating behaviors during travel.

Abstract
Here, we report an unusual case of invasive gnathostomiasis in a returning traveller, with a shifting pattern of relapsing cutaneous disease. The previously fit and well 32-year-old man first presented with serpiginous, pruriginous erythematous tracks characteristic of cutaneous larva migrans shortly after returning from South-East Asia. He was systemically well with no other symptoms. After ivermectin therapy, he re-presented with respiratory symptoms, peripheral eosinophilia and transient pulmonary infiltrates; the classic triad of Löffler's syndrome associated with invasive helminth infection. Gnathostoma spinigerum immunoblot was positive. After a second round of ivermectin therapy his respiratory symptoms resolved, but the patient's cutaneous disease relapsed repeatedly over months, with migratory erythematous swellings appearing and settling after a few days. He was treated with a 21-day course of albendazole and is lesion free at 40 weeks post initial presentation.

Abstract
Human gnathostomiasis caused by third-stage Gnathostoma spinigerum larvae (G. spinigerum L3) is an important zoonotic disease in tropical areas of the world. The excretory-secretory products (ES) that are excreted by infective larva play a significant role in host immune evasion and tissue destruction. To investigate the poorly understood mechanisms of G. spinigerum L3 pathogenesis, we focused on the potential effect of ES on inducing apoptosis in human immune cells by using human peripheral blood mononuclear cells (PBMCs) as a model. Early and late apoptosis of PBMCs were assessed following the exposure of these cells to G. spinigerum L3 ES (0.1, 0.5, and 1.0 μg/ml) for 6-48 h. The apoptotic cells were identified by flow cytometric staining of PBMC with FITC-annexin V and propidium iodide. The expression of regulatory genes related to apoptosis mechanisms in ES-treated PBMCs was investigated using a Human Apoptosis RT2 Profiler™ PCR Array. The results showed significant levels of early phase apoptosis at 18 h and of late phase apoptosis at 24 h. We speculate that this apoptosis in PBMCs occurs via the extrinsic pathway. Apoptosis in the ES-induced PBMCs was observed as quickly as 90 min after exposure, and the highest effect was observed at 18-24 h. Furthermore, ES can trigger apoptosis lasting for 48 h. Our findings expand the understanding of one of the mechanisms involved, immune-evasive strategy mechanism used by G. spinigerum larvae during human gnathostomiasis.

Abstract
Eosinophilc meningitis is commonly associated with Angiostrongylus and Gnathostoma infection and has largely been reported from Thailand. We present the first case report of neurognathostomaisis in a pediatric patient from India. A 3.5 year old girl presented with fever, parasthesis, behavioral changes followed by flaccid quadriparesis. Neuroimaging showed haemorrhagic radiculomyelitis with cerebrospinal fluid eosinophilia. Diagnosis of Gnathostoma infection was confirmed serologically and she was treated with anthelminthic drugs and steroids. This report emphasizes the increasing importance of central nervous system helminithic infections as an alternative diagnosis to common infections like neurotuberculosis in developing countries, even in pediatric patients. Increasing intercontinental travel and migration have increased the incidence and importance in the developed world as well.

Abstract
AbstractCerebral involvement in parasitoses is an important clinical manifestation of most of the human parasitoses. Parasites that have been described to affect the central nervous system (CNS), either as the dominant or as a collateral feature, include cestodes (Taenia solium (neurocysticerciasis), Echinococcus granulosus (cerebral cystic echinococcosis), E. multilocularis (cerebral alveolar echinococcosis), Spirometra mansoni (neurosparganosis)), nematodes (Toxocara canis and T. cati (neurotoxocariasis), Trichinella spiralis (neurotrichinelliasis), Angiostrongylus cantonensis and A. costaricensis (neuroangiostrongyliasis), Gnathostoma spinigerum (gnathostomiasis)), trematodes (Schistosoma mansoni (cerebral bilharziosis), Paragonimus westermani (neuroparagonimiasis)), or protozoa (Toxoplasma gondii (neurotoxoplasmosis), Acanthamoeba spp. or Balamuthia mandrillaris (granulomatous amoebic encephalitis), Naegleria (primary amoebic meningo-encephalitis), Entamoeba histolytica (brain abscess), Plasmodium falciparum (cerebral malaria), Trypanosoma brucei gambiense/rhodesiense (sleeping sickness) or Trypanosoma cruzi (cerebral Chagas disease)). Adults or larvae of helminths or protozoa enter the CNS and cause meningitis, encephalitis, ventriculitis, myelitis, ischaemic stroke, bleeding, venous thrombosis or cerebral abscess, clinically manifesting as headache, epilepsy, weakness, cognitive decline, impaired consciousness, confusion, coma or focal neurological deficits. Diagnosis of cerebral parasitoses is dependent on the causative agent. Available diagnostic tools include clinical presentation, blood tests (eosinophilia, plasmodia in blood smear, antibodies against the parasite), cerebrospinal fluid (CSF) investigations, imaging findings and occasionally cerebral biopsy. Treatment relies on drugs and sometimes surgery. Outcome of cerebral parasitoses is highly variable, depending on the effect of drugs, whether they are self-limiting (e.g. Angiostrongylus costaricensis) or whether they remain undetected or asymptomatic, like 25% of neurocysticerciasis cases.

Abstract
Although helminth infections of the central nervous system (CNS) are rare, their public health implications must not be neglected. Indeed, several helminth species can cause cerebrospinal infections, especially if humans serve as intermediate or non-permissive host. The diagnosis of cerebrospinal helminthiases is difficult, and the detection of parasites in cerebrospinal fluid is rarely successful. Cerebrospinal helminth infections therefore often remain undetected, and hence prognosis is poor. Increases in tourism and population movements are risk factors for cerebrospinal helminthiases and infections pose particular challenges to clinicians in non-endemic areas. In this review, we focus primarily on food-borne helminthiases that are endemic and often emerging in Southeast Asia and the Far East, namely angiostrongyliasis, gnathostomiasis, sparganosis, paragonimiasis and cysticercosis. Additionally, we discuss neuroschistosomiasis, a disease that is transmitted through human-water contact. For each disease, we describe the pathogen, its transmission route and possible mechanisms for entering the CNS. We also summarise common signs and symptoms, challenges and opportunities for diagnosis, treatment, clinical management, geographical distribution and epidemiology. The adoption of a comprehensive set of diagnostic criteria for different cerebrospinal helminthiases is proposed, including epidemiological history, typical signs and symptoms, neuroimaging and laboratory findings. Finally, risk factors, and research needs for enhanced patient management and population-based control measures are discussed.

Abstract
INTRODUCTION Human gnathostomiasis is a parasitic disease caused by the ingestion of foods contaminated with the larvae of various species of Gnathostoma. This zoonosis is currently endemic in Asia and Central America. CASE REPORT A 46-year-old French woman resident in Vietnam presented with intermittent pruritic swelling of the hand, present for one year, coupled with eosinophilia. The patient's history and serological testing confirmed the suspected diagnosis of gnathostomiasis. A favorable outcome was attained on treatment with albendazole. DISCUSSION This case, together with several others recently reported in France and Europe, underlines the need to inform travelers and migrants to endemic regions of the risks associated with eating raw or marinated fish.

Abstract
Globalization has produced an increase in the number of people at risk for contracting parasitic infection. Central nervous system infection by nematodal parasites can be devastating. Early recognition and treatment of infection can significantly decrease morbidity of the parasitic infection, as well as the risk of secondary superinfection. The clinical presentation, diagnosis, and treatment for five of the more common nematodal infections of the nervous system--Angiostrongylus spp., Baylisacaris procyonis, Gnathostoma spinigerum, Strongyloides stercoralis, and Toxocara spp.--is reviewed.

Abstract
AN INCIDENTAL HELMITHIASIS IN MAN: Gnathostomiasis is an helminthic disease of animals due to a nematode belonging to the gender Gnathostoma. This gender includes many species, the most frequent being Gnathostoma spinigerum. Man is an incidental host. Human gnathostomiasis is endemic in some countries of South-East Asia, and Latin America. It is due to the consumption of raw or insufficiently cooked meat or fish. Since the beginning of the eighties, there is an increasing number of cases of gnathostomiasis described in Western countries in travellers returning from endemic countries. IN THE SKIN OR THE VISCERA: Gnathostomiasis is a cause of cutaneous and/or visceral larva migrans syndrome. Some visceral involvement, more particularly neurological forms, may lead to significant morbidity and mortality. The diagnosis is occasionally confirmed by the identification of the Gnathostoma larva in the skin or viscera. Most often the diagnosis relies on epidemiological, clinical and biological (hypereosinophilia, positive serologic test) grounds. ALBENDAZOLE AND IVERMECTINE: The first line treatment is albendazole, 400 mg once or twice a day during 21 days. The efficacy of ivermectin needs to be assessed more precisely. Relapses may occur up to 24 months after apparent cure.
