Assessment of the presence of multidrug-resistant Escherichia coli, Salmonella and Staphylococcus in chicken meat, eggs and faeces in Mymensingh division of Bangladesh. Heliyon 2024; 10:e36690. [PMID: 39281621 PMCID: PMC11401041 DOI: 10.1016/j.heliyon.2024.e36690] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Revised: 08/19/2024] [Accepted: 08/20/2024] [Indexed: 09/18/2024] Open
Abstract
The emergence of bacteria that is resistant to several drugs of clinical importance poses a threat to successful treatment, a phenomenon known as multidrug resistance that affects diverse classes of antibiotics. The purpose of this study was to evaluate the prevalence of multidrug-resistant Escherichia coli, Salmonella spp. and Staphylococcus aureus in chicken egg, meat and faeces from four districts of Bangladesh. A total of 120 chicken samples were collected from different poultry farms. Conventional culture and molecular detection methods were used for identification of bacterial isolates from the collected samples followed by antibiotic susceptibility test through the disc diffusion method, finally antibiotic resistant genes were detected by PCR. E. coli, Salmonella spp. and Staphylococcus aureus were detected in meat, egg and faecal samples. Antimicrobial susceptibility results revealed isolates from faeces were 100 % resistant to amoxicillin, while all S. aureus and Salmonella sp. from faeces were resistant to doxycycline, tetracycline and erythromycin. Salmonella spp. isolates from eggs indicated 100 % resistance to erythromycin, amoxycillin, while E. coli were 100 % resistant to erythromycin. E. coli and S. aureus from meat were 100 % resistant to amoxicillin and erythromycin. However, Salmonella spp. from eggs were 100 % susceptible to doxycycline, gentamicin, levofloxacin and tetracycline. The mecA and aac(3)-IV genes were only found in S. aureus and E. coli, respectively. The Sul1, tetB, and aadA1 were highest in Salmonella spp. and S. aureus, while the sul1, tetA and bla SHV were higher in E. coli. Isolates from all samples were multidrug resistant. These findings indicate a high risk of transmission of resistance genes from microbial contamination to food of animal origin. The study emphasizes the need for effective biosecurity measures, responsible antibiotic use, and strict regulations in poultry production to prevent the spread of antibiotic resistance.

Conjugative Transfer of Acute Hepatopancreatic Necrosis Disease-Causing pVA1-Type Plasmid Is Mediated by a Novel Self-Encoded Type IV Secretion System. Microbiol Spectr 2022; 10:e0170222. [PMID: 36121241 PMCID: PMC9602635 DOI: 10.1128/spectrum.01702-22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Accepted: 09/01/2022] [Indexed: 12/31/2022] Open
Abstract
The pathogenic pVA1-type plasmids that carry pirAB toxin genes are the genetic basis for Vibrio to cause acute hepatopancreatic necrosis disease (AHPND), a lethal shrimp disease posing an urgent threat to shrimp aquaculture. Emerging evidence also demonstrate the rapid spread of pVA1-type plasmids across Vibrio species. The pVA1-type plasmids have been predicted to encode a self-encoded type IV secretion system (T4SS). Here, phylogenetic analysis indicated that the T4SS is a novel member of Trb-type. We further confirmed that the T4SS was able to mediate the conjugation of pVA1-type plasmids. A trbE gene encoding an ATPase and a traG gene annotated as a type IV coupling protein (T4CP) were characterized as key components of the T4SS. Deleting either of these 2 genes abolished the conjugative transfer of a pVA1-type plasmid from AHPND-causing Vibrio parahaemolyticus to Vibrio campbellii, which was restored by complementation of the corresponding gene. Moreover, we found that bacterial density, temperature, and nutrient levels are factors that can regulate conjugation efficiency. In conclusion, we proved that the conjugation of pVA1-type plasmids across Vibrio spp. is mediated by a novel T4SS and regulated by environmental factors. IMPORTANCE AHPND is a global shrimp bacteriosis and was listed as a notifiable disease by the World Organization for Animal Health (WOAH) in 2016, causing losses of more than USD 7 billion each year. Several Vibrio species such as V. parahaemolyticus, V. harveyi, V. campbellii, and V. owensii harboring the virulence plasmid (designated as the pVA1-type plasmid) can cause AHPND. The increasing number of Vibrio species makes prevention and control more difficult, threatening the sustainable development of the aquaculture industry. In this study, we found that the horizontal transfer of pVA1-type plasmid is mediated by a novel type IV secretion system (T4SS). Our study explained the formation mechanism of pathogen diversity in AHPND. Moreover, bacterial density, temperature, and nutrient levels can regulate horizontal efficiency. We explore new ideas for controlling the spread of virulence plasmid and form the basis of management strategies leading to the prevention and control of AHPND.

Abstract
Objective: Vibrio spp., particularly, Vibrio cholerae is a major etiology of diarrhea in humans worldwide. In this study, we isolated and identified V. cholerae from the human stool of suspected cases along with antibiogram. Materials and Methods: In total, 25 stool samples from cholera suspected patients were analyzed. Isolation and molecular detection of Vibrio species were performed based on staining, motility, cultural and biochemical characteristics followed by polymerase chain reaction (PCR) using groEL gene-specific primers. Results: Among the 25 samples, seven showed growth of yellow color colonies on Thiosulfate-Citrate-Bile salts-Sucrose agar plates. The isolates were Gram-negative, curved shaped, and motile. Biochemically, they were found positive for indole and Methyl Red tests and negative for Voges–Proskauer test. Out of the seven positive samples, only three isolates were confirmed as Vibrio spp. using genus-specific primers. Subsequently, these three isolates were confirmed as V. cholerae by PCR using V. cholerae groEL gene-specific primers. Antibiotic sensitivity test revealed these three isolates as highly sensitive to azithromycin, chloramphenicol, gentamicin, and norfloxacillin while resistant to streptomycin, tetracycline, and oxacillin. Conclusion: Vibrio cholerae were isolated from the stool of diarrheic human patients and confirmed by PCR targeting the groEL gene. The isolates were found resistant to streptomycin, tetracycline and oxacillin, and need further characterization to reveal the molecular basis of their origin and resistance.

Abstract
Acute hepatopancreatic necrosis disease (AHPND) has caused sharp declines in aquaculture industries of whiteleg shrimp Penaeus vannamei in Asia and the Americas since 2010. Vibrio parahaemolyticus, V. campbellii, V. owensii, and V. punensis have been proved to cause AHPND. However, the mechanisms underlying the burgeoning number of Vibrio species that cause AHPND is not known. All of AHPND-causing Vibrio bacteria (VAHPND) harbor a highly homologous plasmid (designated as pVA1-type) carrying pirABvp toxin genes. In this study, we demonstrate conclusively that the pVA1-type plasmid can be transferred from VAHPND to non-pathogenic bacteria. We constructed a pVPGX1-Cmr plasmid (a pVA1-type plasmid) by adding a chloramphenicol resistance gene as a marker in a donor AHPND-causing V. parahaemolyticus 20130629002S01 (Vp2S01). Horizontal transfer of this plasmid was successfully performed from the AHPND-Vp2S01 to a non-pathogenic strain of V. campbellii at the transfer efficiency of 2.6×10−8 transconjugant/recipient, and DNase I treatment did not eliminate the transfer. The recipient V. campbellii acquired the pVA1-type plasmid and was shown to produce pirABvp RNA and proteins. Challenge studies using the transconjugant caused 100% mortality in exposed groups of P. vannamei. The challenged shrimp, infected with the transconjugant bacteria, showed typical gross signs and histological lesions of AHPND. These results demonstrated the conjugative transfer of an AHPND pVA1-type plasmid. It provides timely information for explaining the increased species of AHPND-causing Vibrio bacteria and will be useful in the development of management strategies leading to the prevention and control of AHPND.

Abstract
Singleplex and duplex loop-mediated isothermal amplification (LAMP) assays were developed for detecting Vibrio anguillarum, a major bacterial pathogen of fish, and Vibrio alginolyticus, a pathogen of fish and humans, separately and simultaneously from contaminated seawater by targeting the groEL gene of V. anguillarum, which encodes a molecular chaperone protein, and the fklB gene of V. alginolyticus, which encodes a 22 kilodalton (kDa) peptidyl prolyl isomerase. The optimal reaction conditions to produce consistent results were 65 °C for 30 min, 63 °C for 30 min, and 63 °C for 40 min for the groEL (singleplex for V. anguillarum), fklB (singleplex for V. alginolyticus), and groEL + flkB (duplex) LAMP assays, respectively, analyzed via visual detection methods (use of calcein, and SYBR Green I) and agarose gel electrophoresis. The assays were found to be species-specific, as closely related Vibrio spp. were not detected. The limits of detection (LoDs) of the LAMP assays for DNA template from pure culture and artificially contaminated seawater were 10 and 14 fg (groEL assay; for V. anguillarum), 12.5 and 17 fg (fklB assay; for V. alginolyticus), and 50 and 70 fg (duplex assay) per reaction, respectively, which were much better than the LoDs of conventional polymerase chain reaction (PCR). Singleplex and duplex LAMP assays were found to be rapid, species-specific, and sensitive for the detection of V. anguillarum and V. alginolyticus and are applicable to laboratory and field diagnostics.

Abstract
Vibrio parahaemolyticus is a common and important pathogen that causes human gastroenteritis worldwide. A rapid, sensitive, and specific assay is urgently required for detection and differentiation of V. parahaemolyticus strains. We designed three sets of primers and probes using groEL and two virulence genes (tdh and trh) from V. parahaemolyticus, and developed a multiplex real-time PCR protocol. The sensitivity and specificity of the multiplex assay was evaluated by environmental and clinical specimens of V. parahaemolyticus. The multiplex PCR response system and annealing temperature were optimized. The detection limits of the multiplex real-time PCR were 104 and 105 CFU/mL (or CFU/g) in pure cultures and spiked oysters, respectively. The multiplex real-time PCR specifically detected and differentiated V. parahaemolyticus from 35 Vibrio strains and 11 other bacterial strains. Moreover, this method can detect and distinguish virulent from nonvirulent strains, with no cross-reactivity observed in the bacteria tested. This newly established multiplex real-time PCR assay offers rapid, specific, and reliable detection of the total and pathogenic V. parahaemolyticus strains, which is very useful during outbreaks and sporadic cases caused by V. parahaemolyticus infection.

Abstract
A groEL gene-based loop-mediated isothermal amplification (LAMP) assay was developed to detect Vibrio parahaemolyticus in contaminated seafood and water. The assay was optimized and conducted at 63°C for 40 min using Bacillus stearothermophilus (Bst) DNA polymerase, large fragment. Amplification was analysed via multiple detection methods, including opacity, formation of white precipitate, DNA intercalating dyes (ethidium bromide and SYBR Green I), metal ion-binding indicator dye, calcein, and 2% agarose gel electrophoresis. A characteristic ladder-like band pattern on agarose gel and the desired colour changes when using different dyes were observed in positive cases, and these were species-specific for V. parahaemolyticus when compared with other closely related Vibrio spp. The limit of detection (LoD) of this assay was 100 fg per reaction, 100-fold higher than that for conventional polymerase chain reaction (PCR). When tested on artificially contaminated seafood and seawater, the LoDs of the LAMP assay were 120 and 150 fg per reaction respectively, and those of conventional PCR were 120 and 150 pg per reaction respectively. Based on our results, the groEL gene-based LAMP assay is rapid, specific, sensitive, and reliable for detecting V. parahaemolyticus, and it could be used in field diagnosis. SIGNIFICANCE AND IMPACT OF THE STUDY The loop-mediated isothermal amplification (LAMP) assay using groEL gene (an abundant, highly conserved gene and member of the groESL chaperone gene family) provided rapid, species-specific and highly sensitive method for detecting Vibrio parahaemolyticus, the leading causal agent of seafood-borne diseases worldwide. Moreover, groEL LAMP revealed high efficiency than conventional PCR assay for V. parahaemolyticus using template both from pure culture and artificially contaminated seafood and water, which indicated the applicability in the field and environmental screening purpose for the organism.

Abstract
Important pathogenic Vibrio species were differentiated by PCR-restriction fragment length polymorphism analysis. A 1117-bp groEL gene product was amplified using universal primers and digested using the restriction enzymes NruI or XbaI, revealing unique digestion patterns for each of the 10 Vibrio species, of which 7 were pathogenic in humans, along with 2 other species pathogenic in fish.

Abstract
Vibrio parahaemolyticus is a significant cause of human gastrointestinal disorders worldwide, transmitted primarily by ingestion of raw or undercooked contaminated seafood. In this study, a multiplex PCR assay for the detection and differentiation of V. parahaemolyticus strains was developed using primer sets for a species-specific marker, groEL, and two virulence markers, tdh and trh. Multiplex PCR conditions were standardised, and extracted genomic DNA of 70 V. parahaemolyticus strains was used for identification. The sensitivity and efficacy of this method were validated using artificially inoculated shellfish and seawater. The expected sizes of amplicons were 510 bp, 382 bp, and 171 bp for groEL, tdh and trh, respectively. PCR products were sufficiently different in size, and the detection limits of the multiplex PCR for groEL, tdh and trh were each 200 pg DNA. Specific detection and differentiation of virulent from non-virulent strains in shellfish homogenates and seawater was also possible after artificial inoculation with various V. parahaemolyticus strains. This newly developed multiplex PCR is a rapid assay for detection and differentiation of pathogenic V. parahaemolyticus strains, and could be used to prevent disease outbreaks and protect public health by helping the seafood industry maintain a safe shellfish supply.

Development of a groEL gene-based species-specific multiplex polymerase chain reaction assay for simultaneous detection of Vibrio cholerae, Vibrio parahaemolyticus and Vibrio vulnificus. J Appl Microbiol 2012; 114:448-56. [PMID: 23121500 DOI: 10.1111/jam.12056] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2012] [Revised: 10/17/2012] [Accepted: 10/26/2012] [Indexed: 11/29/2022]
Abstract
AIMS To develop an effective multiplex polymerase chain reaction (PCR) for the simultaneous detection of three important Vibrio species, Vibrio cholerae (Vc), V. parahaemolyticus (Vp) and V. vulnificus (Vv) using the groEL gene, a potential phylogenetic marker. METHODS AND RESULTS Three species-specific primer sets were designed to target Vc, Vp and Vv. A total of 131 Vibrio and non-Vibrio strains were used to determine the specificity and sensitivity of primers. The primers produced specific PCR fragments from all target species strains and did not cross-react with other Vibrio and non-Vibrio species. This PCR method showed good efficiency in detecting coexisting target species in the same sample with a detection limit of 100 pg of Vc, Vp and Vv from mixed purified DNA. Detection of three target species was also possible from artificially inoculated shellfish, flounder and sea water. CONCLUSIONS The groEL gene is a potential marker for accurate simultaneous detection of Vc, Vp and Vv and could be used to detect these species in environmental and clinical samples. SIGNIFICANCE AND IMPACT OF THE STUDY This newly developed multiplex PCR is a useful and cost-effective method that is applicable in a disease-outbreak prediction system and may provide an effective tool for both the epidemiologist and ecologist.

Development of a real time PCR assay for rapid detection of Vibrio parahaemolyticus from seafood. Protein Cell 2012; 3:204-12.

Abstract
A real time PCR assay for the detection of Vibrio parahaemolyticus in seafood samples was developed using a novel specific target and a competitive internal amplification control (IAC). The specificity of this assay was evaluated using 390 bacterial strains including V. parahaemolyticus, and other strains belonging to Vibrio and non-Vibrio species. The real time PCR assay unambiguously distinguished V. parahaemolyticus with a detection sensitivity of 4.8 fg per PCR with purified genomic DNA or 1 CFU per reaction by counting V. parahaemolyticus colonies. The assays of avoiding interference demonstrated that, even in the presence of 2.1 μg genomic DNA or 10(7) CFU background bacteria, V. parahaemolyticus could still be accurately detected. In addition, the IAC was used to indicate false-negative results, and lower than 94 copies of IAC per reaction had no influence on the detection limit. Ninety-six seafood samples were tested, of which 58 (60.4%) were positive, including 3 false negative results. Consequently, the real time PCR assay is effective for the rapid detection of V. parahaemotyticus contaminants in seafood.
