“…Furthermore, ascending vaginal colonization is supported by the finding of listerial colonization solely in the firstborn of a set of twins [56] However, haematogenous spread may be more likely, and documented maternal bacteriuria and in utero fetal infection with positive amniotic fluid cultures prior to labor have been recorded [94]. In addition, nosocomial cross-infection has been reported [37,115,133] 55,115,116]. …”

Listeria is commonly found in processed and prepared foods and listeriosis is associated with high morbidity and mortality. Preventative measures are well prescribed and monitoring and voluntary recall of contaminated products has resulted in a 44% reduction in the prevalence of perinatal listeriosis in the USA. Pregnant women are at high risk for listeriosis, but symptoms are non-specific and diagnosis is difficult. The intracellular life-cycle of Listeria protects the bacterium from host innate and adaptive immune responses. Antibiotic treatment requires agents able to penetrate, distribute, and remain stable within host cells. Prolonged use of high-dose ampicillin can significantly improve neonatal outcome.

“…Recently, several molecular genotyping methods such as DNA restriction endonuclease analysis [5], ribotyping [1], multilocus enzyme electrophoresis [14] and pulsed-field gel electrophoresis (PFGE) [3] have been developed. However, most of these methods are not always convenient for routine use in ordinary clinical laboratories because of their requirement of special instruments and skilled personnel.…”

ABSTRACT. Twenty epidemiologically unrelated Listeria monocytogenes strains isolated from different animals, locations and on different dates in Japan were classified into 18 types by the random amplified polymorphic DNA (RAPD) fingerprinting technique with four primers. Further, seven epidemiologically related L. monocytogenes strains isolated from raw milk and a bulk tank on a dairy farm represented the same RAPD type suggesting that they were all of the same origin. Therefore, RAPD-polymerase chain reaction (PCR) analysis, which is rapid, simple and inexpensive to perform, can be used in surveys as a convenient epidemiological technique.-KEY WORDS: Listeria monocytogenes, RAPD-PCR, typing.

“…Late onset neonatal listeriosis is less common and occurs more frequently in infants who are healthy at birth from uncomplicated pregnancies and normal maternal health (4). Transmission in late onset listeriosis is assumed to occur during passage through the birth canal, or via nosocomial infection of the infant (5). Average age for onset of clinical disease is 14.3 days and is more commonly associated with meningitis than sepsis.…”

The objectives of this study were to develop an animal model to study Listeria monocytogenes infection during the peri-parturient period and identify sources of maternal shedding of the pathogen. Peri-parturient mice were infected intragastrically with L. monocytogenes that expressed bacterial luciferase. Mice were then imaged in vivo over time. Secreted breast milk samples from mice infected after parturition were enriched and plated for culture and imaging. Bioluminescence imaging technology was able to detect luciferase emitting L. monocytogenes in vaginal secretions and maternal and fetal organs at 72 and 96 h post infection in mice infected prior to, or just after, parturition. The results from this study clearly show that L. monocytogenes is shed in vaginal secretions and disseminates to the mammary chain, from which it can be shed in the milk of peri-parturient mice.
