“…This value is similar to that described in Italy 19 and Thailand 28 ; however, it is much less than that reported in Germany, 29 Mexico, 30 and the United States. 31 No particular serovar was predominant in our study, although other reports have claimed a more frequent distribution of serovars Grippotyphosa, Icterohaemorrhagiae, Australis, and Canicola.…”

[28][29][30][31][32] Such discrepancies may be because of the relatively limited number of animals used or differences in climatic or geographical conditions.…”

Abstract. A survey of 179 animals (black rats, dogs, sheep, buffaloes, cattle, donkeys, weasels, and cats) for Leptospira infection was conducted in Mahalla City (Lower Egypt). Blood, urine, and kidney were collected and tested by culture, microscopic agglutination test (MAT), and/or polymerase chain reaction (PCR). Among rats, 26% were positive by PCR, including 7% that were also positive by culture for L. interrogans serovars Grippotyphosa, Pyrogenes, and Icterohaemorrhagiae. L. borpetersenii serovar Polonica was isolated for the first time in Egypt in three rats. MAT titers ≥ 1:800 were observed in 11% of rats and 12% of dogs. L. interrogans serovar Grippotyphosa was detected in one cat. Sheep and donkeys were negative for leptospirosis by all methods. Buffaloes and cattle were seropositive in 20% and 44% of animals, respectively. Data indicate that several pathogenic serovars are circulating in the animals, which may pose exposure risks and account for high rates of acute febrile illness.

“…In our study, Leptospira serovars that had the highest reactivity (i.e., titer) were considered to be the possible infecting serovar. 45,46 However, we cannot determine if this finding is caused by past or current infections because we only had single serum samples. Furthermore, cross-reactions, especially between serogroups, are often observed in the MAT.…”

“…Because our study involves isolation of leptospires from rats, we could only collect single, not paired, samples. Therefore, in this study, the serovar with the highest titer was considered to be the presumptive infecting serovar 45,46 and serum with this result was classified as being infected with single Leptospira serovar. However, if two or more serovars induced the highest titer, then the infection was considered to be probably caused by multiple serovars.…”

Abstract. Rats are known to be the most important reservoirs and transmission sources of leptospirosis. However, the status of leptospirosis in the Philippines regarding reservoirs and transmission remains unknown. A survey was conducted in Metro Manila and Laguna that analyzed samples obtained from 106 rats. Using the microscopic agglutination test, we found that 92% of rat serum samples were positive for anti-Leptospira antibodies; the most common infecting serovars were Manilae, Hebdomadis, and Losbanos. On the basis of pulsed-field gel electrophoresis and gyrase B gene sequence analyses, four groups of rat kidney isolates were found: L. interrogans serovar Manilae, serovar Losbanos, and serogroup Grippotyphosa, and L. borgpetersenii serogroup Javanica. Most isolates were lethal after experimental infection of golden Syrian hamsters. Results showed that these four Leptospira serovars and serogroups are circulating among rats, and that these animals may be one of the possible transmission sources of leptospirosis in the Philippines.

“…Grippotyphosa was also reported as one of the most common causes of clinical leptospirosis in humans and dogs in Germany (6,11,12). Serovar Grippotyphosa is maintained by a number of small rodents in Europe: the common vole (Microtus arvalis) (4,10,14), muskrat (Ondatra zibethicus) (7), common hamster (Cricetus cricetus) (16), wood mouse (Apodemus sylvaticus), and yellow-necked mouse (Apodemus flavicollis) (19,21).…”

Introduction: Recently in Europe an increase in the population of red deer (Cervus elaphus), roe deer (Capreolus capreolus), and fallow deer (Dama dama) has been observed. Research on the prevalence of Leptospira infections in Polish cervids has been performed for the first time. Material and Methods: During 2014/2015 hunting season, 147 blood samples from red deer, roe deer, and fallow deer were collected. The animals originated from different geographical regions across Poland. Serum samples were tested by microscopic agglutination test (MAT) for the presence of specific antibodies to the following Leptospira serovars: Icterohaemorrhagiae, Grippotyphosa, Sejroe, Tarassovi, Pomona, Canicola, Bratislava, Hardjo, Ballum, Zanoni, Hebdomadis, and Poi. Results: Serum antibody titres specific to Grippotyphosa, Pomona, and Zanoni serovars were found; none of the sera were positive for any of the other serovars. Out of 147 serum samples only 7 were positive, which gave an overall prevalence of 4.8% in the tested animal population. Conclusion: The low Leptospira antibody titres along with the low number of positive serum samples in deer indicate that these animals may not act as significant reservoirs of Leptospira for either humans or animals in Poland.
