Costinar L, Badea C, Marcu A, Pascu C, Herman V. Multiple Drug Resistant Streptococcus Strains-An Actual Problem in Pig Farms in Western Romania. Antibiotics (Basel) 2024; 13:277. [PMID: 38534712 DOI: 10.3390/antibiotics13030277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 03/17/2024] [Accepted: 03/18/2024] [Indexed: 03/28/2024] Open
Abstract
Streptococci are a type of bacteria that can cause severe illnesses in humans and animals. Some typical species like S. suis, or atypical species like S. porcinus and, S. dysgalactiae subsp. dysgalactiae, can cause infections like septicemia, meningitis, endocarditis, arthritis, and septic shock. S. suis is considered a newly emerging zoonotic pathogen. Although human streptococcal infection outbreaks are rare, it is appropriate to review the main streptococcal species isolated in pig farms in western Romania, due to the high degree of antibiotic resistance among most isolates commonly used in human treatment. This study examines the resistance patterns of these isolates over 5 years (2018-2023). The research investigated the antimicrobial susceptibility of 267 strains of Streptococcus spp. isolated from pigs, primarily from lung and brain tissues. This report is the first to describe the distribution of atypical Streptococcus species (SDSE, S. porcinus, S. hyovaginalis, S. pluranimalium, S. canis) in Romania, as well as the antibiotic resistance profile of these potentially zoonotic species. It is important to re-evaluate and consider the high rates of resistance of S. suis to tetracyclines, lincosamides, macrolides, and aminoglycosides, as well as the high recovery rates of S. suis from the lungs and brain when treating swine diseases.

Abstract
Host innate immunity plays a pivotal role in the early detection and neutralization of invading pathogens. Here, we show that pseudokinase mixed lineage kinase-like protein (MLKL) is required for host defence against Streptococcus pluranimalium infection by enhancing NLRP3 inflammasome activation and extracellular trap formation. Notably, Mlkl deficiency leads to increased mortality, increased bacterial colonization, severe destruction of organ architecture, and elevated inflammatory cell infiltration in murine models of S. pluranimalium pulmonary and systemic infection. In vivo and in vitro data provided evidence that potassium efflux-dependent NLRP3 inflammasome signalling downstream of active MLKL confers host protection against S. pluranimalium infection and initiates bacterial killing and clearance. Moreover, Mlkl deficiency results in defects in extracellular trap-mediated bactericidal activity. In summary, this study revealed that MLKL mediates the host defence response to S. pluranimalium, and suggests that MLKL is a potential drug target for preventing and controlling pathogen infection.

Abstract
BACKGROUND: The limited amount of information available today does not fully reflect the biological properties of Streptococcus pluranimalium as a pathogen new to humans, its pathogenicity factors, and, as a consequence, the pathogenesis of diseases, which is causes
AIM: The aim of this research was to study the biological properties of S. pluranimalium, its sensitivity to antibiotics and antiseptics, as well as its adhesive properties.
METHODS: Two hundred samples were collected from the coronal pockets in patients with acute purulent pericoronitis during 2019–2021 years. Among them, five clinical strains of S. pluranimalium were isolated. Final identification was carried out using a Vitec-2compact bioMérieux automatic bacteriological analyzer. The sensitivity of the studied microbial strains to antibiotics of various groups was determined by the disk diffusion method. The adhesive properties of S. pluranimalium were determined according to the standard Brilis method.
RESULTS: It possesses typical morphological and cultural properties characteristics of the genus Streptococcus representatives. This microorganism virtually does not break down carbohydrates, but it produces arylamidases that enables it to be differentiated from other streptococci. S. pluranimalium demonstrates variable sensitivity to antibiotics; the lowest sensitivity has been found out to the second-generation fluoroquinolones. In addition, the clinical isolates studied show high adhesive properties to human red blood cells.
CONCLUSIONS: S. pluranimalium is increasingly acting as the causative agent of human infectious diseases. The information available today fully reflects the biological properties of a pathogen new to humans, its pathogenicity factors.

Post-traumatic endophthalmitis caused by streptococcus species in preschool children: clinical features, antibiotic susceptibilities and outcomes. Eye (Lond) 2022; 36:95-101. [PMID: 33627757 PMCID: PMC8727608 DOI: 10.1038/s41433-021-01449-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2020] [Revised: 01/04/2021] [Accepted: 01/27/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND/OBJECTIVES Streptococcus is a common cause of post-traumatic endophthalmitis in children. This study aimed to analyse the clinical features, antibiotic susceptibilities and outcomes of traumatic endophthalmitis caused by streptococcus in preschool children. SUBJECTS/METHODS Patients aged ≤6 years with traumatic streptococcal endophthalmitis seen at Zhongshan Ophthalmic Center between January 2013 and December 2018 were included in this retrospective study. RESULTS In total, 21 patients (21 eyes) were included. The mean age of the patients was 3.3 ± 1.7 years, where 57.1% were males. Scissors (28.6%, n = 6) were the most common cause of injury; 86.7% of patients were injured at home. Zone I (80.9%) was the most common wound site; 90.5% of patients presented with a traumatic cataract. In general, Streptococcus pneumoniae (47.6%) was the most common isolate. Viridans group streptococci accounted for 58.3% of cases in children aged 0-3 years, while S. pneumoniae accounted for 66.7% of cases in children aged 4-6 years. The susceptibility rates of streptococcus to cefuroxime, levofloxacin and ofloxacin were 100%, 95.0% and 90.5%, respectively. Although all the patients underwent vitrectomy combined with silicone oil tamponade, the final visual outcomes were no better than counting fingers. CONCLUSIONS Although S. pneumoniae was the most prevalent organism in general, the dominant species varied between different age groups. The commonly used antibiotics, cefuroxime and fluoroquinolone, showed higher antibiotic susceptibility. Despite prompt treatment, the visual outcomes of paediatric post-traumatic endophthalmitis in preschool children were poor.

Abstract
The Streptococcus pluranimalium was isolated from both of animals and human infection. There is limited information about pathogenicity of S pluranimalium. As fastidious bacteria, S pluranimalium is not isolated in the routinely culture media and easily misidentified with other streptococci species with conventional microbiology test. According to review of the literatures, the cephalosporins, aminoglycosides, vancomycin, and linezolid are the first choice agents for treatment of infection caused by S pluranimalium.

Abstract
The genus Streptococcus includes Gram-positive organisms shaped in cocci and organized in chains. They are commensals, pathogens, and opportunistic pathogens for humans and animals. Most Streptococcus species of veterinary relevance have a specific ecological niche, such as S. uberis, which is almost exclusively an environmental pathogen causing bovine mastitis. In contrast, S. suis can be considered as a true zoonotic pathogen, causing specific diseases in humans after contact with infected animals or derived food products. Finally, Streptococcus species such as S. agalactiae can be sporadically zoonotic, even though they are pathogens of both humans and animals independently. For clarification, a short taxonomical overview will be given here to highlight the diversity of streptococci that infect animals. Several families of antibiotics are used to treat animals for streptococcal infections. First-line treatments are penicillins (alone or in combination with aminoglycosides), macrolides and lincosamides, fluoroquinolones, and tetracyclines. Because of the selecting role of antibiotics, resistance phenotypes have been reported in streptococci isolated from animals worldwide. Globally, the dynamic of resistance acquisition in streptococci is slower than what is experienced in Enterobacteriaceae, probably due to the much more limited horizontal spread of resistance genes. Nonetheless, transposons or integrative and conjugative elements can disseminate resistance determinants among streptococci. Besides providing key elements on the prevalence of resistance in streptococci from animals, this article will also largely consider the mechanisms and molecular epidemiology of the major types of resistance to antimicrobials encountered in the most important streptococcal species in veterinary medicine.

Abstract
Background Streptococcus pluranimalium is a new member of the Streptococcus genus isolated from multiple different animal hosts. It has been identified as a pathogen associated with subclinical mastitis, valvular endocarditis and septicaemia in animals. Moreover, this bacterium has emerged as a new pathogen for human infective endocarditis and brain abscess. However, the patho-biological properties of S. pluranimalium remain virtually unknown. The aim of this study was to determine the complete genome sequence of S. pluranimalium strain TH11417 isolated from a cattle with mastitis, and to characterize its antimicrobial resistance, virulence, and carbon catabolism. Results The genome of S. pluranimalium TH11417, determined by single-molecule real-time (SMRT) sequencing, consists of 2,065,522 base pair (bp) with a G + C content of 38.65%, 2,007 predicted coding sequence (CDS), 58 transfer RNA (tRNA) genes and five ribosome RNA (rRNA) operons. It contains a novel ISSpl1 element (a memeber of the IS3 family) and a Ф11417.1 prophage that carries the mef(A), msr(D) and lnu(C) genes. Consistently, our antimicrobial susceptibility test confirmed that S. pluranimalium TH11417 was resistant to erythromycin and lincomycin. However, this strain did not show virulence in murine pneumonia (intranasal inoculation, 107 colony forming unit – CFU) and sepsis (intraperitoneal inoculation, 107 CFU) models. Additionally, this strain is able to grow with glucose, lactose or galactose as the sole carbon source, and possesses a lactose-specific phosphoenolpyruvate-dependent phosphotransferase system (PTS). Conclusions We reported the first whole genome sequence of S. pluranimalium isolated from a cattle with mastitis. It harbors a prophage carrying the mef(A), msr(D) and lnu(C) genes, and is avirulent in the murine infection model.

Abstract
BACKGROUND Streptococcus pluranimalium is a new and emerging animal streptococcal species associated with primary infection in bovine and avian species. Data in the literature regarding its pathogenic significance in human beings are limited. We hereby report a case of brain abscess caused by S. pluranimalium in a healthy adult male. S. pluranimalium, a causative agent of brain abscess, was unanticipated, and to the best of our knowledge, this is one of the rare cases reported in the medical literature. CASE DESCRIPTION A 44-year-old male presented with headache and occasional episodes of vomiting for 2 weeks, weakness of the left upper and lower limbs for 1 week, and 1 episode of generalized tonic clonic seizure 2 days back. He was afebrile and had no history of loss of consciousness or head trauma. His physical and neurologic examination was unremarkable. Magnetic resonance imaging of the brain revealed a focal ring enhancing lesion in right posterior parietal lobe, suggestive of infective etiology. The patient underwent right parietooccipital craniotomy and excision of cerebral abscess, from which S. pluranimalium was isolated. The patient responded to treatment with intravenous ceftriaxone, vancomycin, and metronidazole without any residual neurologic sequelae. CONCLUSION Clinical data regarding epidemiology, pathogenic mechanisms, and zoonotic potential of S. pluranimalium in human beings are lacking. The number of cases of human infections with S. pluranimalium are steadily increasing. Hence further detailed study of the pathogenesis of S. pluranimalium in human beings is warranted, which may help to develop new strategies to prevent and treat infection with this bacterium.

Abstract
Background The present investigation was an endeavor into the elucidation of the disease-causing pathogen of streptococcosis in Nile tilapia (Oreochromis niloticus) in Egypt affecting adult fish cultured and wild fish in the Nile river. Fish were obtained from commercial fishermen, collected as part of their routine fishing activities. The researchers observed the routine fishing process and selected fish for use in the study, at the point of purchase from the fisherman. Results Diseased fish showed exophthalmia with accumulation of purulent and haemorrhagic fluid around eyes, and ventral petechial haemorrhages. The Post mortem examination revealed, abdominal fat haemorrhage, pericarditis and enlargement of the liver, spleen and kidney. Gram-stained smears revealed the presence of Gram-positive cocci, β-hemolytic, oxidase and catalase negative. Analysis of the 16S rRNA gene confirmed that the 17 tilapia isolates studied were 6/17 Enterococcus faecalis, 2/17 Enterococcus gallinarum, 3/17 Streptococcus pluranimalium, 2/17 Aerococcus viridans, 1/17 isolate of each Streptococcus dysgalactiae, Streptococcus anginosus, Lactococcus garvieae and Granulicetella elegans/Leuconostoc mesenteroides cremoris. It should be noted that there was no mixed infection. Multiple resistance was observed and the most frequent antibiotic combination was penicillin, ampicillin, vancomycin, chloramphenicol, rifampicin, ofloxacin, clindamycin, erythromycin and tetracycline representing eight classes. Conclusions Consequently, we concluded that Streptococcus species are an emerging pathogen for Nile tilapia aquaculture in Egypt and to be considered as a new candidate in the warm water fish diseases in Egypt with special reference to L. garvieae, S. dysgalactiae in addition to L. mesenteroides cremoris which was not reported before from tilapia and taking into consideration their zoonotic implications for public health.

Abstract
Streptococcus pluranimalium as a novel human pathogen has been reported by several authors in various contexts. In all reported cases in humans the microorganism was detected by the Vitek2®. The great advances with the introduction of new analytical techniques such as MALDI-TOF or 16S rRNA analysis enabled a more detailed discrimination of pathogens such as these nonhemolytic streptococci. In the cases of such similar gene sequences such techniques are absolutely essential to identify the exact strain for this highly conserved 16S rRNA gene. However, until now neither a sequence analysis of the 16S rRNA gene nor PCR nor MALDI-TOF techniques could define Streptococcus pluranimalium in humans. We conclude that according to our best present knowledge there exists no conclusive evidence for a human infection of Streptococcus pluranimalium even when using most advanced and exact identification techniques until now.

Short communication: Role of Streptococcus pluranimalium in Mediterranean buffaloes (Bubalus bubalis) with different udder health statuses. J Dairy Sci 2016; 99:2945-2949. [PMID: 26805969 DOI: 10.3168/jds.2015-10291] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2015] [Accepted: 12/06/2015] [Indexed: 11/19/2022]
Abstract
The aims of the current study were to describe presence and clinical role over time of Streptococcus pluranimalium isolated in milk samples of Mediterranean buffalo (MB). Two hundred composite milk samples originating from 40 primiparous MB were collected at 10, 30, 60, 90, and 150d in milk (DIM) and from 20 pluriparous MB at 77 to 120 DIM. Milk samples were used for analysis of somatic cell counts, bacteriological cultures, and identification (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry). Nine of 200 (4.5%) samples of primiparous MB and 3 of 20 (15%) samples of pluriparous MB were positive for Strep. pluranimalium. The prevalence of the bacterium in primipari was 0% (0/40) at 10, 30, and 150 DIM, whereas it was 5 (2/40) and 17.5% (7/40) at 60 and 90 DIM, respectively. Eight primipari were positive only once, whereas 1 was positive at 2 different samplings. Mono-infection was not detected in any of the age categories or udder health status. Infections were transient in primipari. Clinical mastitis was observed in primipari once at 90 DIM, subclinical mastitis detected twice in the same animals at 60 and 90 DIM, and intramammary infections were diagnosed 1 and 5 times at 60 and 90 DIM in primipari, respectively, whereas 3 infections were diagnosed in pluripari. The clinical reflections demonstrate for the first time the presence of Strep. pluranimalium in MB and its association with different udder health status. Nevertheless, it cannot be excluded that the bacterium may simply follow a pattern of commensal or opportunistic behavior, taking advantage of a preexisting bacterial udder infection.
