Abstract
Non-cholera Vibrio spp. includes ubiquitous organisms living in aquatic environments. Their occurrence is associated with global warming and meteorological disasters. In May 2023 the Romagna region, Italy, was affected by severe floods. In the following 15 weeks we observed 5 patients with invasive infections caused by V. vulnificus (3/5) and V. harveyi (2/5). All patients (median age 77 years) had medical comorbidities and shared exposure to seawater. Two patients needed surgery; 2 died. In conclusion, we observed an increased burden of Vibrio spp. invasive infections after May 2023 floods, affecting old patients with predisposing medical conditions.

Prevalence of Bacterial Coinfections with Vibrio harveyi in the Industrialized Flow-through Aquaculture Systems in Hainan Province: A Neglected High-Risk Lethal Causative Agent to Hybrid Grouper. Int J Mol Sci 2022; 23:ijms231911628.

Abstract
Vibrio harveyi is one of the most serious bacterial pathogens to aquatic animals worldwide. Evidence is mounting that coinfections caused by multiple pathogens are common in nature and can alter the severity of diseases in marine animals. However, bacterial coinfections involving V. harveyi have received little attention in mariculture. In this study, the results of pathogen isolation indicated that bacterial coinfection was a common and overlooked risk for hybrid groupers (♀ Epinephelus polyphekadion × ♂ E. fuscoguttatus) reared in an industrialized flow-through pattern in Hainan Province. The artificial infection in hybrid groupers revealed that coinfections with V. harveyi strain GDH11385 (a serious lethal causative agent to groupers) and other isolated pathogens resulted in higher mortality (46.67%) than infection with strain GDH11385 alone (33.33%), whereas no mortality was observed in single infection with other pathogens. Furthermore, the intestine, liver and spleen of hybrid groupers are target organs for bacterial coinfections involving V. harveyi. Based on the infection patterns found in this study, we propose that V. harveyi may have a specific spatiotemporal expression pattern of virulence genes when infecting the host. Taken together, bacterial coinfection with V. harveyi is a neglected high-risk lethal causative agent to hybrid groupers in the industrialized flow-through aquaculture systems in Hainan Province.

Vibrio harveyi infections induce production of proinflammatory cytokines in murine peritoneal macrophages via activation of p38 MAPK and NF-κB pathways, but reversed by PI3K/AKT pathways. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2022; 127:104292.

Abstract
Vibrio harveyi is a zoonotic pathogen that can infect humans through wounds and cause severe inflammatory responses. Previous studies have reported that the Toll like receptors (TLR) mediated MAPK, AKT and NF-κB signaling pathways are involved in innate immune system resistance to pathogen invasion. However, the molecular mechanism of these pathways, as well as their involvement in V. harveyi infection remains elusive. This study established a V. harveyi infection model using murine peritoneal macrophages (PMs). Various techniques, including western blotting, ELISA, RT-qPCR, immunofluorescence, inhibition assays, were used to explore the roles of TLRs, MAPK, AKT and NF-κB signaling pathways in V. harveyi-induced inflammatory responses. ELISA assays showed that V. harveyi infection triggered proinflammatory cytokines secretion in PMs. RT-qPCR and inhibition assays showed that TLR2 participated in V. harveyi infection and up-regulated the proinflammatory cytokines secretion in murine PMs. Western blotting data showed that the phosphorylation of p38, JNK, AKT, and NF-κB p65 were significantly increased partly mediated by TLR2. In addition, immunofluorescence assays revealed that the NF-κB p65 translocated into nucleus in response to V. harveyi infection. The secretion of IL-1β, IL-6, IL-12, and TNF-α were considerably reduced when the p38 MAPK and NF-κB signaling pathways were blocked, whereas blocking of AKT significantly increased the expression of IL-1β, IL-6, IL-12, and TNF-α. These findings indicate that V. harveyi infection induces inflammatory responses in murine PMs via activation of p38 MAPK and NF-κB pathways, which are partly mediated by TLR2, but are inhibited by PI3K/AKT pathways.

Abstract
Vibrio harveyi, an important zoonotic pathogen, can infect wounds and cause inflammatory response. Understanding the inflammatory response pathways could facilitate the exploration of molecular mechanisms for treating V. harveyi infection. NLR family pyrin domain-containing 3 (NLRP3) inflammasome is involved in the interaction between hosts and pathogenic microorganisms and could be sensed by various pathogen-associated molecular patterns (PAMPs) or damage-associated molecular patterns (DAMPs). Nonetheless, the function of NLRP3 inflammasome in V. harveyi infection remains unclear. In the present study, we established a V. harveyi infection model using murine peritoneal macrophages (PMs). Various techniques, including western blot analysis, enzyme-linked immunosorbent assay (ELISA), RT-qPCR, immunofluorescence, and inhibition assays, were used to explore the molecular mechanism of V. harveyi-induced inflammation. The results showed that many inflammatory cytokines participated in V. harveyi infection, with interleukin (IL)-1β being the most abundant. Pan-caspase inhibitor pretreatment significantly decreased the secretion of IL-1β in murine PMs. Moreover, the identification of V. harveyi involved a large number of NLR molecules, especially the NLRP3 receptor, and further studies revealed that NLPR3 inflammasome was activated by V. harveyi infection, as evidenced by puncta-like NLRP3 surrounding cell nuclear, ASC specks in the nucleus and cytoplasm, and ASC oligomerization. Inhibition of NLRP3 inflammasome impaired the release of mature IL-1β in V. harveyi-infected murine PMs. Furthermore, blocking the secretion of mature IL-1β could markedly decrease the release of other proinflammatory cytokines, including IL-6, IL-12, and tumor necrosis factor-α. Overall, these data indicated that NLRP3 inflammasome was activated in response to V. harveyi infection and enhanced inflammatory response by promoting IL-1β secretion in murine PMs.

Abstract
A pathogen was isolated from diseased pink-tailed chalceus Chalceus macrolepidotus during a high-mortality outbreak in a freshwater culture farm in Liaoyang, China. The diseased fish were characterized by disoriented behaviors, exophthalmos, and redness and swelling of the top of the head. A Gram-negative, pure strain of bacteria (CM0428) was isolated from the brain, kidney, and liver. The isolate was identified as Vibrio cholerae based on ompW gene amplification and 16S rRNA and gyrB gene sequence analysis. Serogroup testing indicated that CM0428 was a non-O1/O139 strain of V. cholerae. The challenge test showed that CM0428 exhibited strong virulence to pink-tailed chalceus, and hlyA and toxR virulence-related genes were detected. The isolate was sensitive to multi-class antibiotics, but resistant to tetracycline. Histological examination revealed that V. cholerae CM0428 infection caused multiple organ and tissue lesions, and typical pathological features were cell degeneration and necrosis.

Abstract
Vibrio harveyi is a marine bacterial pathogen which infects a wide range of marine organisms and results in severe loss. Antibiotics have been used for prophylaxis and treatment of V. harveyi infection. However, antibiotic resistance is a major public health threat to both human and animals. Therefore, there is an urgent need for novel antimicrobial agents with new modes of action. In V. harveyi, many virulence factors production and bioluminescence formation depend on its quorum sensing (QS) network. Therefore, the QS system has been widely investigated as an effective potential target for the treatment of V. harveyi infection. This perspective focuses on the quorum sensing inhibitors (QSIs) of V. harveyi QS systems (LuxM/N, LuxS/PQ, and CqsA/S) and evaluates medicinal chemistry strategies.

Abstract
BACKGROUND Vibrio spp. are aquatic bacteria that are ubiquitous in warm estuarine and marine environments, of which 12 species are currently known to cause infections in humans. So far, only five human infections with V. harveyi have been reported. CASE PRESENTATION A 26-year old patient was transferred to our center by inter-hospital air transfer from Mallorca, Spain. Seven days before, he had suffered a complete amputation injury of his left lower leg combined with an open, multi-fragment, distal femur fracture after he had been struck by the propeller of a passing motorboat while snorkeling in the Mediterranean Sea. On admission he was febrile; laboratory studies showed markedly elevated inflammatory parameters and antibiotic treatment with ampicillin/sulbactam was initiated. Physical examination showed a tender and erythematous amputation stump, so surgical revision was performed and confirmed a putrid infection with necrosis of the subcutaneous tissue and the muscles. Tissue cultures subsequently grew V. harveyi with a minimal inhibitory concentration (MIC) of 16 mg/L for ampicillin, and antibiotic treatment was switched to ceftriaxone and ciprofloxacin. Throughout the following days, the patient repeatedly had to undergo surgical debridement but eventually the infection could be controlled, and he was discharged. CONCLUSIONS We report the first human infection with V. harveyi acquired in Spain and the second infection acquired in the Mediterranean Sea. This case suggests that physicians and microbiologists should be aware of the possibility of wound infections caused by Vibrio spp. acquired in the ocean environment, especially during hot summer months. Since Vibrio spp. preferentially grow at water temperatures above 18 °C, global warming is responsible for an abundance of these bacteria in coastal waters. This will likely lead to a worldwide increase in reports of Vibrio-associated diseases in the future.

Recent studies suggest that some adaptation mechanisms can easily be acquired by V. harveyi and other members of the Vibrionaceae family owing to efficient horizontal gene transfer and elevated mutation rate. While discussing the main factors in charge of the expansion of Vibrio spp. habitats and concomitant spread of Vibrio-associated diseases under climate change, this review highlights the need for future studies able to address the joint impact of environmental and anthropogenic factors on the long-term dynamics and virulence of V. harveyi populations at the global scale.

Abstract
Vibrio harveyi hemolysin (VHH) is considered a major pathogenic virulence factor to fish. However, the VHH active-site mutant has lost all hemolytic and phospholipase activities as well as pathogenicity. In this study, the effect of VHH on erythrocytes and a gill cell line from flounder was elucidated. Erythrocyte membranes formed thin tubular protrusions immediately after exposure to VHH, and membrane corrugations were evident after extended incubation. In contrast, the mutant VHH did not induce any gross morphological changes. With VHH-treated FG-9307 cells, a cell line derived from flounder gill, destruction of organelles and formation of features resembling apoptotic bodies were observed. Immunogold staining showed that a large amount of VHH was deposited on the membranes and membrane debris of erythrocytes and FG-9307 cells after treatment with VHH. Apoptotic features, such as chromatin condensation and apoptotic bodies, were observed in VHH-treated FG-9307 cells using DAPI staining. Moreover, cell cycle analysis showed that VHH increased the proportion of cells in G1 phase. In addition, VHH significantly increased the percentage of apoptosis, the number of TUNEL positive apoptotic cells, and caspase-3 activity in FG-9307 cells when compared with the untreated controls. These data suggested that VHH killed the cells through apoptosis via the caspase activation pathway.
