Variable antigens of Ureaplasma urealyticum containing both serovar-specific and serovar-cross-reactive epitopes [PDF]

Infection and Immunity, 1990
Currently there are 14 recognized serovars of Ureaplasma urealyticum, and it has been postulated that only certain ones may be associated with disease and that lack of serovar-specific antibody may be an important risk factor. Unfortunately, ureaplasma antigens important in the human immune response and disease pathogenesis are poorly defined. By using

Genotyping Reveals Potential Sources of Human Leptospirosis Outbreaks in Aotearoa New Zealand. [PDF]

Zoonoses Public Health
ABSTRACT Introduction The introduction of PCR testing for leptospirosis in Aotearoa New Zealand has reduced the availability of serotyping data, and current diagnostic PCRs do not routinely genotype Leptospira. This study genotyped Leptospira from PCR‐confirmed human cases between 2016 and 2023 and compared them with genotypes found in animals to ...

Loss of very-long O-antigen chains optimizes capsule-mediated immune evasion by Salmonella enterica serovar Typhi. [PDF]

, 2013
UnlabelledExpression of capsular polysaccharides is a variable trait often associated with more-virulent forms of a bacterial species. For example, typhoid fever is caused by the capsulated Salmonella enterica serovar Typhi, while nontyphoidal Salmonella

Salmonella enterica: Survival, Colonization, and Virulence Differences among Serovars

TheScientificWorldJournal, 2015
Data indicate that prevalence of specific serovars of Salmonella enterica in human foodborne illness is not correlated with their prevalence in feed. Given that feed is a suboptimal environment for S.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Prevalence, serotype distribution, and antimicrobial resistance of Salmonella isolated from food products in Morocco

Journal of Infection in Developing Countries, 2017
Introduction: Salmonellosis is one of the most common foodborne diseases worldwide. The irrational use of antibiotics in medicine and in animal feed has greatly promoted the emergence and spread of resistant strains of non-typhoidal Salmonella ...

Prevalence of Salmonella Isolates and Their Distribution Based on Whole-Genome Sequence in a Chicken Slaughterhouse in Jiangsu, China

Frontiers in Veterinary Science, 2020
Salmonella has been known as the most important foodborne pathogen, which can infect humans via consuming contaminated food. Chicken meat has been known as an important vehicle to transmit Salmonella by the food supply chain.

Chlamydial infection from outside to inside [PDF]

, 2019
Chlamydia are obligate intracellular bacteria, characterized by a unique biphasic developmental cycle. Specific interactions with the host cell are crucial for the bacteria's survival and amplification because of the reduced chlamydial genome.

Genomic Comparison Among Global Isolates of L. interrogans Serovars Copenhageni and Icterohaemorrhagiae Identified Natural Genetic Variation Caused by an Indel

Frontiers in Cellular and Infection Microbiology, 2018
Leptospirosis is a worldwide zoonosis, responsible for more than 1 million cases and 60,000 deaths every year. Among the 13 pathogenic species of the genus Leptospira, serovars belonging to L.
