Streptococcus suis strains with novel and previously undescribed capsular loci circulate in Europe.

Streptococcus suis (S. suis) causes serious diseases in pigs, and certain serotypes also pose a risk to humans. The expression of capsular polysaccharides (CPS) is considered an important virulence property of the pathogen.

Characterisation of Isolates in the Czech Republic Collected from Diseased Pigs in the Years 2018-2022.

As in other countries, in the Czech Republic, infection in pigs is considered an economically significant disease for the pig industry, though little is known about its population structure. We collected isolates from 144 farms in the years 2018-2022. All samples were taken from animals suffering from symptoms indicating possible infection.

Vaccine against Infection in Pig Based on Alternative Carrier Protein Conjugate.

is a serious pathogen in the pig industry with zoonotic potential. With respect to the current effort to reduce antibiotic use in animals, a prophylactic measure is needed to control the disease burden. Unfortunately, immunization against streptococcal pathogens is challenging due to nature of the interaction between the pathogen and the host immune system, but vaccines based on conjugates of capsular polysaccharide (CPS) and carrier protein were proved to be efficient.

Resistance of Isolates from the Czech Republic during 2018-2022.

A determination of susceptibility/resistance to antimicrobials via serotype was carried out in 506 field isolates of , originating from pig farms in the Czech Republic in the period 2018-2022. A very high level of susceptibility of isolates was found to amoxicillin, in combination with clavulanic acid and sulfamethoxazole potentiated with trimethoprim. None of the tested isolates were resistant to these antimicrobial substances.

Experimental Evidence of the Long-Term Survival of Infective African Swine Fever Virus Strain Ba71V in Soil under Different Conditions.

The survival of African swine fever virus (ASFV) on different matrices and its infectivity in wild as well as domestic swine is still a matter of interest. ASFV is resistant to environmental effects; this fact is enhanced by the presence of organic material. Therefore, the aim of this work was to determine the ability of laboratory ASFV to survive in soil at different temperatures (4 and 22 °C) and with and without the presence of blood using culture procedures.

Isolates-Serotypes and Susceptibility to Antimicrobials in Terms of Their Use on Selected Repopulated Czech Pig Farms.

represents a primary health problem (such as meningitis, septicemia and arthritis in piglets and fatteners) in the swine industry worldwide and also an emerging zoonotic pathogen. In the Czech Republic, many pig farms repopulated their herds over the past decades to reduce morbidity and minimize treatment. The study analysed serotypes, sequence types and antimicrobial susceptibility in 39 isolates obtained from organs of diseased pigs from selected 16 repopulated farms with a history of -associated diseases and routine antimicrobial treatment with tulathromycin and/or amoxicillin.

Fatal toxoplasmosis in wild European brown hares (Lepus europaeus) in tularaemia endemic areas of the Czech Republic: Poses risk of infection for humans?

Toxoplasma gondii may cause fatal infection in European brown hares (Lepus europaeus). However, the role of this parasite in terms of mortality rate in tularaemia endemic areas, amount of parasites in affected organs and circulating genotypes, is still unknown. In total, 36 hares (killed or found dead) were submitted for pathomorphological examination as a part of the national tularaemia and brucellosis monitoring.

Wild boar as a potential reservoir of zoonotic tick-borne pathogens.

The wild boar (Sus scrofa) population has increased dramatically over the last decades throughout Europe and it has become a serious pest. In addition, the common habitat of wild boar and of the tick, Ixodes ricinus, indicates the potential of wild boar to play a role in epidemiology of epizootic and zoonotic tick-borne pathogens, including Anaplasma phagocytophilum. In Europe, epidemiological cycles and reservoirs of A.

Resolution of Streptococcus suis Serotypes 1/2 versus 2 and 1 versus 14 by PCR-Restriction Fragment Length Polymorphism Method.

is an important pathogen of pigs but is also transmissible to humans, with potentially fatal consequences. Among 29 serotypes currently recognized, some are clinically and epidemiologically more important than others. This is particularly true for serotypes 2 and 14, which have a large impact on pig production and also on human health.
