Oliveira HGDS, Sousa AIDJ, Zanon IP, Lopes CTDA, Silva ROS, Domingues SFS, Salvarani FM. Occurrence of Clostridium perfringens in Wild Mammals in the Amazon Biome. Animals (Basel) 2024; 14:1333. [PMID: 38731335 PMCID: PMC11083269 DOI: 10.3390/ani14091333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 04/18/2024] [Accepted: 04/18/2024] [Indexed: 05/13/2024] Open
Abstract
The objective of this study was to evaluate the occurrence of Clostridium perfringens in stool samples and swabs collected from wild mammals in the Amazon biome. Sixty-five faecal and swab samples were collected in situ and ex situ from 16 species and three genera of wild mammals, some of which were in good health and some of which had diarrhoea. After pre-enrichment, the samples were plated on selective agar for C. perfringens. Characteristic colonies were subjected to multiplex PCR for the detection of genes encoding the main C. perfringens toxins (alpha, beta, epsilon, and iota toxin and enterotoxin). Among the 65 samples, 40 (61.5%) were positive for the gene encoding the alpha toxin and were classified as type A, 36 of which were asymptomatic animals and four were diarrheal. No other toxinotypes were found. The findings of this study suggest that C. perfringens type A is commonly found in mammal species of the Amazon biome. This seems to be the first study to identify C. perfringens type A in species such as B. variegatus (common ground sloth), C. didactylus (two-toed sloth), P. flavus (Jupará), T. tetradactyla (anteater), S. collinsi (squirrel monkey), S. niger (black marmoset), and S. apella (Guyana capuchin) and in the genus Didelphis sp. (opossum).

Abstract
The scientific information regarding staphylococci in procyonids is scarce. Hence, the aim of this study was to evaluate the frequency, distribution, and pattern of antimicrobial resistance of staphylococcal species isolated from free-roaming coatis (Nasua nasua) in an urban park in Belo Horizonte, Minas Gerais, Brazil. Rectal swabs from 55 free-living coatis were plated onto mannitol salt agar for isolating staphylococci, and species were identified using matrix-assisted laser desorption/ionization-time of flight mass spectrometry, polymerase chain reaction (PCR) of nuc, and sequencing of 16S rRNA and rpoB when needed. Antimicrobial susceptibility was investigated using the disk diffusion method, and the presence of the mecA gene was investigated by PCR. A total of 72.7% of the animals tested positive for staphylococci. Nine different species were identified, and Staphylococcus intermedius (60.4%) and S. delphini (20.9%) were the most frequently isolated species. Most of the isolates were susceptible to most of the antimicrobials evaluated, with a resistance pattern seen for penicillin (13.9%). One isolate was multidrug-resistant (MDR). The present study suggests that coatis are natural hosts of S. intermedius and S. delphini and, despite living in a heavily anthropized environment, the Staphylococcus spp. isolates showed a low incidence of drug resistance.

Characterization of coccidiosis and evaluation of suggestive cases of subclinical necrotic enteritis in broilers. PESQUISA VETERINÁRIA BRASILEIRA 2023.

Abstract
ABSTRACT: This study performed the characterization of coccidiosis in broilers and evaluated the occurrence of suggestive cases of necrotic enteritis (NE), seeking if there is an association between the diseases in Brazilian flocks. Two hundred and fifty-six birds from 32 flocks were evaluated. Macroscopic and histopathological lesions were graduated for coccidiosis and NE. Intestinal content was investigated by polymerase chain reaction (PCR) for seven species of Eimeria and by selective anaerobic culture for Clostridium perfringens and identification of the NetB gene. Flocks positive for coccidiosis represented 93.8%. Macroscopic lesions of coccidiosis were Grade 1 for E. acervulina (27%); E. tenella (9.7%) and E. maxima (8.9%). Histopathological evaluation showed Grade 1 in duodenum (38.2%); jejunum (21.4%); cecum (9.3%) and ileum (5%). PCR demonstrated positivity for E. tenella (21.9%), E. maxima (18.8%), and E. acervulina (3.1%). Suggestive macroscopic lesions of necrotic enteritis ranged from Grade 1 (16%), 2 (23%) and 3 (10,9%). Histopathology indicated the absence of necrosis, showing only hemorrhage in the mucosa and submucosa, with the presence of Eimeria spp. Clostridium perfringens type A netB+ was not isolated, demonstrating that macroscopic lesions found mostly in the jejunum did not characterize NE, based on histopathology and negativity of the NetB gene. The study suggests that, due to the high occurrence of coccidiosis, many macroscopic findings suggestive of NE are, in fact, attributed to atypical lesions caused by the reproduction of Eimeria spp.

Yadav JP, Kaur S, Dhaka P, Vijay D, Bedi JS. Prevalence, molecular characterization, and antimicrobial resistance profile of Clostridium perfringens from India: A scoping review. Anaerobe 2022; 77:102639. [PMID: 36108893 DOI: 10.1016/j.anaerobe.2022.102639] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 04/27/2022] [Accepted: 09/07/2022] [Indexed: 11/01/2022]
Abstract
Clostridium perfringens is one of the most important foodborne pathogens that causes histotoxic diseases and intestinal infections in both humans and animals. The present scoping review has been designed to analyze the literature published during 2000-2021 from India on the prevalence, molecular characterization, and antimicrobial resistance profile of C. perfringens isolates recovered from humans, animals, animal-based foods, and associated environmental samples. The peer-reviewed articles retrieved from four electronic databases (Google Scholar, PubMed, Science Direct, and Web of Science) were assessed using PRISMA-ScR guidelines. A total of 32 studies from India were selected on the basis of their relevance and inclusion criteria. The overall prevalence of C. perfringens among domestic animals having history of clinical symptoms and among healthy animals was found to be 65.8% (508/772) and 42.8% (493/1152), respectively. The pathogen was also detected in clinically affected wild animals (75%), healthy wild animals (35.4%), and captive birds (24.5%). The detection of C. perfringens among poultry having necrotic enteritis and among healthy birds was found to be 66.8% (321/480) and 25.6% (80/312), respectively. The detection of pathogen among animal-based foods (i.e., meat, milk, and fish and their products) and environmental samples depicted a prevalence of 20.8% (325/1562) and 30.2% (23/76), respectively. However, the prevalence of C. perfringens among humans having history of diarrhea and among healthy humans was found to be 25% (70/280) and 23.2% (36/155), respectively. The genotyping of C. perfringens isolates revealed that toxin type A was found to be the most prevalent genotype. Along with the alpha toxin gene (cpa), beta (cpb), epsilon (etx), iota (itx), enterotoxin (cpe), beta-2 toxin (cpb2), and NetB (netB) toxins were also detected in different combinations. Antimicrobial resistance profile of C. perfringens isolates recovered from different sources demonstrated that the highest resistance was detected against sulphonamides (76.8%) and tetracycline (41.3%) by phenotypic and genotypic detection methods, respectively. Comprehensive scientific studies covering different geographical areas at the human-animal-environment interface are crucial to generalize the real magnitude of C. perfringens-associated problem in India and for establishing a reliable database.

Abstract
Wild environments and wildlife can be reservoirs of pathogens and antibiotic resistance. Various studies have reported the presence of zoonotic bacteria, resistant strains, and genetic elements that determine antibiotic resistance in wild animals, especially near urban centers or agricultural and zootechnical activities. The purpose of this study was the analysis, by cultural and molecular methods, of bacteria isolated from wild animals in Sicily, Italy, regarding their susceptibility profile to antibiotics and the presence of antibiotic resistance genes. Bacteriological analyses were conducted on 368 wild animals, leading to the isolation of 222 bacterial strains identified by biochemical tests and 16S rRNA sequencing. The most isolated species was Escherichia coli, followed by Clostridium perfringens and Citrobacter freundii. Antibiograms and the determination of resistance genes showed a reduced spread of bacteria carrying antibiotic resistance among wild animals in Sicily. However, since several wild animals are becoming increasingly close to residential areas, it is important to monitor their health status and to perform microbiological analyses following a One Health approach.

Abstract
There is little information on the anatomical pathology of Brazilian anteaters. Considering the relevance of knowledge of diseases of these species for their conservation, the aim of this study was to describe pathological changes in 99 captive and free-ranging anteaters from the Brazilian states of São Paulo, Minas Gerais, Bahia, Mato Grosso do Sul and Amazonas. Forty-two animals were killed on roads and 10 died from burns injuries. Other significant conditions included the metabolic diseases of iron storage disease, tissue mineralization and taurine deficiency, protozoan and metazoan infections, candidiasis, sporotrichosis, clostridiosis and proliferative disorders including squamous cell carcinoma.

First Microbiological and Molecular Identification of Rhodococcus equi in Feces of Nondiarrheic Cats. BIOMED RESEARCH INTERNATIONAL 2019; 2019:4278598.

Abstract
Rhodococcus equi is responsible for infections in multiple-host animals. In humans, the prevalence of rhodococcus has increased worldwide and represents an emergent risk. R. equi is a soil-borne opportunistic bacterium isolated from feces of a wide variety of domestic species, except cats; thus, there is no known potential risk of its transmission from humans. Here, the mono- and cooccurrence of Rhodococcus equi and other bacteria and selected virulence markers were investigated in feces of nondiarrheic cats from urban (n=100) and rural (n=100) areas. Seven (7/200=3.5%) R. equi isolates were recovered in ceftazidime, novobiocin, and cycloheximide (CAZ-NB) selective media, exclusively of cats from three distinct farms (p=0.01), and these cats had a history of contact with horses and their environment (p=0.0002). None of the R. equi isolates harbored hosted-adapted plasmid types associated with virulence (pVAPA, pVAPB, and pVAPN). One hundred seventy-five E. coli isolates were identified, and 23 atypical enteropathogenic E. coli (aEPEC), 1 STEC (Shiga-toxin producing E. coli), and 1 EAEC (enteroaggregative E. coli) were detected. Eighty-six C. perfringens type A isolates were identified, and beta-2 and enterotoxin were detected in 21 and 1 isolates, respectively. Five C. difficile isolates were identified, one of which was toxigenic and ribotype 106. The main cooccurring isolates in cats from urban areas were E. coli and C. perfringens A (26/100=26%), E. coli and C. perfringens type A cpb2+ (8/100=8%), and aEPEC (eae+/escN+) and C. perfringens type A (5/100=5%). In cats from farms, the main cooccurring isolates were E. coli and C. perfringens type A (21/100=21%), E. coli and C. perfringens type A cpb2+ 8/100=8%), and E. coli and R. equi (4/100=4%). We identified, for the first time, R. equi in nondiarrheic cats, a finding that represents a public health issue because rhodococcus has been reported in both immunosuppressed and immunocompetent humans, particularly people living with HIV/AIDS.

Abstract
Considering the increasing popularity of reptiles as pets and their possible role as reservoirs of pathogenic microorganisms, the aim of this study was to isolate Escherichia coli, Salmonella spp., Clostridium perfringens, and C. difficile strains from reptiles in Brazil and to characterize the isolated strains. The characterization was based on phylogenetic typing of E. coli, identification of virulence genes of E. coli, C. perfringens, and C. difficile, serotyping of Salmonella spp., ribotyping and MLST of C. difficile and antimicrobial susceptibility test of pathogenic strains. Cloacal swabs were collected from 76 reptiles, of which 15 were lizards, 16 chelonians, and 45 snakes, either living in captivity, in the wild, or as companion animals. E. coli was isolated from 52 (68.4%) reptiles, of which 46 (88.4%) were characterized as phylogroup B1. The virulence factor CNF1 of E. coli was found in seven (9.2%) sampled animals, whereas the gene of EAST1 was found in isolates from two (2.6%) reptiles. Three isolates positive for CNF1 were resistant to cephalothin, one of which was also resistant to ciprofloxacin, trimethoprim/sulfamethoxazole, and chloramphenicol, being then classified as multidrug resistant strain (MDR). Salmonella enterica was identified in 26 (34.2%) reptiles, of which 13 belonged to the subspecies enterica. Serotypes such as S. Mbandaka, S. Panama, S. Infantis, S. Heidelberg, and S. Anatum were identified. One isolate of S. enterica subsp. houtenae was resistant to cephalothin and ciprofloxacin. C. perfringens type A was isolated from six (7.8%) animals. C. difficile was isolated from three (3.9%) reptiles. Two of these isolates were toxigenic and classified into ribotypes/MLST 081/ST9 and 106/ST42, which have been previously reported to infect humans. In conclusion, reptiles in Brazil can harbor toxigenic C. difficile and potentially pathogenic E. coli and Salmonella enterica subsp. enterica, thus representing a risk to human and animal health.

Abstract
ABSTRACT The aim of the present study was to isolate Clostridium perfringens and C. difficile in crab-eating fox (Cerdocyon thous) from Northeastern Brazil. Stool samples of 18 captive crab-eating foxes from four states of Northeastern Brazil (Alagoas, Bahia, Paraíba e Pernambuco) were collected and subjected to C. perfringens and C. difficile isolation. Suggestive colonies of C. perfringens were then analyzed for genes encoding the major C. perfringens toxins (alpha, beta, epsilon and iota), beta-2 toxin (cpb2), enterotoxin (cpe), and NetB- (netB) and NetF- (netF) encoding genes. C. difficile strains were analyzed by multiplex-PCR for a housekeeping gene (tpi), toxins A (tcdA) and B (tcdB) and a binary toxin gene (cdtB). Unthawed aliquots of stool samples positive for toxigenic C. difficile were subjected to a commercial ELISA to evaluate the presence of A/B toxins. Clostridium perfringens (type A) was isolated from five (27%) samples, and only one sample was positive for beta-2 enconding gene (cpb2). Two (11%) stool samples were positive for C. difficile, but negative for A/B toxins. These two wild canids were also positive for C. perfringens type A. This is the first report of C. difficile in crab-eating fox.

Abstract
Aim: The study was conducted to report the occurrence of the Clostridium perfringens in sheep and goats of the Kashmir valley for the 1st time and to characterize them molecularly with respect to toxin genes to determine the prevalence of the various toxinotypes. Materials and Methods: A total of 177 samples (152 from sheep and 25 from goats) collected from healthy, diarrheic animals, and morbid material of animals suspected to have died of enterotoxaemia were screened for C. perfringens toxinotypes. The presumptive positive isolates were confirmed using 16S rRNA gene-based polymerase chain reaction (PCR). All the confirmed isolates were screened for six toxin genes, namely; cpa, cpb, etx, cpi, cpb2, and cpe using a multiplex PCR. Results: The PCR amplification of 16S rRNA gene revealed that out of 177 samples collected, 125 (70.62%) were found positive for C. perfringens, of which 110 (72.36%) were from sheep and 15 (60%) were from goats. The highest prevalence of C. perfringens toxinotype D was observed in lambs (56.16%) and kids (46.16%) followed by 3.84% in adult sheep while it was absent in samples obtained from adult goats. The multiplex PCR revealed that 67 (60.90%) isolates from sheep and 8 (53.33%) isolates from goats belonged to toxinotype A, while 43 (39.09%) isolates from sheep and 7 (46.66%) isolates from goats were detected as toxinotype D. None of the isolates was found to be toxinotype B, C, or E. All the C. perfringens toxinotype A isolates from sheep were negative for both cpb2 and cpe genes, however, 27.90% toxinotype D isolates from sheep carried cpb2 gene, and 6.97% possessed cpe gene. In contrast, 12.50% C. perfringens toxinotype A isolates from goats harbored cpb2 and cpe genes while 14.28% isolates belonging to toxinotype D carried cpb2 and cpe genes, respectively. Conclusion: The high prevalence of C. perfringens was observed, even in day-old lambs. The toxinotypes A and D are prevalent in both sheep and goats. The severity of disease and mortality may be associated with the presence of minor toxins in both the detected toxinotypes.

Abstract
Clostridium perfringens is considered one of the important causes of calf diarrhea. Two hundred and twenty-seven clinical samples from newly born and dead diarrheic calves were examined bacteriologically and by PCR. Bacterial culture identified C. perfringens in 168 of 227 samples. A total of 144 of these isolates were lecithinase positive, indicating C. perfringens Type A. In addition, 154 isolates were positive by alpha toxin encoding gene-PCR assay. This study showed high agreement between the results of bacteriology and multiplex PCR. The multiplex PCR typed all isolates that were typed as C. perfringens Type A through bacteriologic methods, but ten samples that were lecithinase negative were positive in the multiplex PCR. The study showed the highest occurrence of C. perfringens Type A isolations from calves during the winter and autumn compared with other seasons.
