Abstract
A novel lytic phage named vB_SlqS_ZDD2 was isolated from hospital sewage using the double-layer agar method with Serratia liquefaciens ATCC 27592 as the host. BLASTn analysis showed that the genome sequence of phage vB_SlqS_ZDD2 did not resemble any other phages in the NCBI database. Phenotype and phylogeny analysis indicated that this phage might be a new member of the class Caudoviricetes. Phage vB_SlqS_ZDD2 has a dsDNA genome of 49,178 bp with 55% GC content and has 73 open reading frames. This phage exhibited strong lytic activity and a wide range of pH (3-12) and temperature tolerance (below 70℃).

Abstract
A novel lytic Serratia liquefaciens phage, named vB_SlqM_MQ-4, was isolated from sewage. BLASTn analysis showed that the genome sequence of phage vB_SlqM_MQ-4 shared only 15% query coverage with that of Escherichia phage vB_EcoM-ep3, with 80.52% identity. Genomic analysis demonstrated that phage vB_SlqM_MQ-4 has a 43,534-bp dsDNA genome with 56% GC content and might be a member of a new genus in the order Caudoviricetes. Moreover, vB_SlqM_MQ-4 exhibited strong lytic performance with a short latent period (10 min) and a high burst size (267 PFU per cell) as well as a wide range of thermal (below 70 ℃) and pH tolerance (pH 4-12).

Abstract
Mating may promote microbial diversity through sexual transmission, while mating-induced immune responses may decrease it. Therefore, the study of mating-induced microbiomes changes under different mating systems is informative to unravel its biological relevance and evolutionary significance. Here, we studied the microbiomes in a community context within the abdomen of Spodoptera frugiperda females using 16S rDNA sequences by setting virgin females, and females mated once, twice, or thrice with the same or different males. Alpha and beta diversities revealed that mating significantly affected the composition of microbiomes in S. frugiperda females, wherein virgin females have the highest diversity, followed by one-time mated females and females mated with multiple males, while females mated repeatedly with the same male showed the lowest diversity. The low diversity in females mated repeatedly with the same male may be due to lower sexual transmission as only mated with one mate and higher immune response from repeated matings. Functional prediction by FAPROTAX and literature searching found 17 possible pathogens and 12 beneficial microbiomes. Multiple mating turned over the abundance of pathogens and beneficial microbes, for example, Enterococcus and Lactobacillus spp. (beneficial) showed higher abundance in virgin females while Morganella and Serratia spp. (pathogens) showed higher abundance in females mated with multiple males. These results suggest that mating causes a decline in the diversity of symbiotic microbiomes and promiscuity incurs a higher pathogen abundance in S. frugiperda females, which may be the result of sexual transmission of bacterial strains and immune responses targeting members of the microbiomes. To our knowledge, we demonstrate microbiomes changes in female insects under virgin and different mating regimes for the first time.

Abstract
Serratia species are facultative anaerobes, non-spore-forming, motile Gram-negative bacteria. Serratia spp. are currently thought to cause a variety of infections, such as bacteremia, urinary tract infections, and pneumonia, as well as other, less common infections, including ocular infections or skin and soft tissue infections. On the other hand, Infective Endocarditis (IE) is an infrequent disease with notable morbidity and mortality. Even though IE is rarely caused by Serratia spp., these infections can be quite problematic due to the lack of experience in their management. This study aimed to systematically review all published cases of IE by Serratia spp. in the literature. A systematic review of PubMed, Scopus, and Cochrane library (through 13th May 2021) for studies providing epidemiological, clinical, microbiological data as well as data on treatment and outcomes of IE by Serratia spp. was performed. In total, 50 studies, containing data for 72 patients, were included. A prosthetic valve was present in 18.1%. The mitral valve was the most commonly infected site, followed by the aortic valve. The diagnosis was facilitated by transthoracic echocardiography in 34.7%, while the diagnosis was set at autopsy in 22.4%. Fever, sepsis, and embolic phenomena were the most common clinical presentations, followed by heart failure. Aminoglycosides, cephalosporins, and carbapenems were the most commonly used antimicrobials. Clinical cure was noted only in 53.5%, while overall mortality was 47.2%. Having surgery along with antimicrobial treatment was independently associated with reduced overall mortality. IE by Serratia spp. was more likely to be associated with intravenous drug use, and to present with heart failure and embolic phenomena compared to IE by other non-HACEK Gram-negative bacilli, while mortality was also higher in IE by Serratia spp.

Abstract
A 14 year-old boy developed infective endocarditis of the mitral valve caused by Methicillin-sensitive Staphylococcus aureus and became comatose. Isolated basilar artery dissection was initially observed on the 3rd day by magnetic resonance imaging (MRI), ie, it did not exist on day 1. He underwent successful urgent mitral valve repair on the 5th day because of highly mobile vegetations and a newly emerged brain infarction under optimal antibiotic administration. Postoperatively, he recovered well and the basilar artery dissection was found to have recovered on an MRI on the 25th day without any specific intervention. This clinical course indicated that intracranial artery dissection may occur as a complication of infective endocarditis and supports the importance of the careful evaluation of brain MRI in patients with infective endocarditis.

Abstract
An incident of sudden deaths in the breeding stock was reported from a farrow-to-finish commercial pig farm in Greece. The 8·4% of sows during lactation and gestation period presented anorexia, fever, haematuria, return-to-oestrus and sudden deaths (mortality rate: 2·3%). Blood and urine samples were collected from four diseased sows. Furthermore, swabs from urine bladders were collected from two dead sows and four culled sows at the slaughterhouse. Blood testing demonstrated mild leucocytosis and absence of azotaemia. Urinalysis revealed haematuria, proteinuria, bilirubinuria and active urine sediment with bacilli, epithelial cells and leucocytes, crystals and granular casts. Histopathological evaluation of the bladder demonstrated chronic active polypoid cystitis. The bacterial culture revealed the presence of Serratia liquefaciens. The antibiotic susceptibility testing showed high resistance to the most common antibiotics, with the highest sensitivity of the isolate towards quinolones. After the administration of a single dose of 7·5 mg kg-1 body weight enrofloxacin intramuscularly, the mortality rate decreased to less than 0·5% along with a remarkable reduction in the severity of clinical signs. Based on our findings, S. liquefaciens induced severe clinical signs and deaths in sows, mainly due to urinary infection. Inadequate water sanitation might have been responsible for increased exposure to S. liquefaciens. SIGNIFICANCE AND IMPACT OF THE STUDY: In this study, the isolation of Serratia liquefaciens from the urinary tract of pigs associated with clinical signs and increased mortality was described for the first time. Serratia liquefaciens is an important cause of hospital-acquired human infections. The isolate in this study was resistant to the most common antibiotics. Therefore, the use of quinolones which are drugs of last resort for treatment of infections was the only therapeutic option. The presence of the resistant bacterium in the urinary tract raises concerns for its zoonotic potential.

Abstract
In Poland, the population of game animals, including wild boars, roe and deer, is constantly increasing. The tonsils of wild game animals are a place of large variety of microorganisms. The pathogenic bacteria present in them, such as E. coli, Y. enterocolitica and Salmonella sp. are the most common source of meat infection. The opportunistic bacteria R. aquatilis, P. fluorescens,
S. liquefaciens, S. fonticola and S. plymuthica also play an important role in public health. S. liquefaciens may be an opportunistic pathogen and in people causes sepsis and inflammation of the
cornea. The protease, nuclease, phospholipase A, flagella, elastase and toxins haemolysin and
proteolysin are responsible for its ability to cause disease symptoms. S. plymuthica, a rod commonly
found in the environment, produces a red dye. It is most often isolated from soil, water
and food. In humans, it causes infections of burn wounds, soft leg tissue as well as post-operative
wounds and bacteraemia. Typically, the environmental rod S. fonticola differs from other Serratia
sp. by the lack of extracellular enzymes. It causes wound infections and bacteraemia resulting
from urinary tract infections. Bacteria from the genus Serratia sp. show a natural resistance
to glycopeptides, rifampicin and erythromycin. The aquatic rod R. aquatilis in humans causes
opportunistic infections of the urinary tract, wounds, bacteraemia and endocarditis. It exhibits
natural resistance to antibiotics from the group of cephalosporins, penicillins and macrolides
and quinolones. It is conditioned by the presence of class 1 integrons and class A β-lactamases.
The virulence factors of R. aquatilis are also LPS and adhesin. P. fluorescens in humans is responsible
for bacteraemia. It also exhibits resistance to human serum thanks to outer membrane
proteins and has T3SS, which effectively infects the host.
