Background. Rickettsia typhi belongs to the typhus group of rickettsiae and causes endemic typhus. Cases of endemic typhus and seropositivity to R. typhi have been reported in the neighbouring China and Russia. However, little is known of the endemic typhus in Kazakhstan. The purpose of this study was to evaluate the prevalence of IgG antibodies to R. typhi in the population of southern region of Kazakhstan. Methods. A total of 253 individuals (142 women, 111 men) aged from 1 to 71 years were recruited into the study. Detection of serum IgG antibodies against R. typhi was performed by enzyme-linked immunosorbent assay (ELISA). Results. The overall R. typhi seropositivity has reached 34.4%. The highest seroprevalence of 91.8% was recorded in the Turkestan Region. The lowest seropositivity of 6.1% was detected in the village Lepsinsk, Almaty Region. The seroprevalence did not differ significantly between genders. Seropositivity in adult individuals was not significantly associated with age, but positive results were not detected in the age group of children under 14 years. Conclusion. The obtained results confirm active circulation of R. typhi in the Turkestan and Almaty Regions of Kazakhstan. The data indicate an urgent need for further studies aimed to evaluate the clinical impact caused by R. typhi in the southern region of Kazakhstan. [ABSTRACT FROM AUTHOR]
Uvod. Rickettsia typhi svrstava se u skupinu pjegavih tifusa i uzrokuje endemski tifus. Slučajevi endemskog tifusa i seropozitivnosti na R. typhi zabilježeni su u susjednoj Kini i Rusiji. Međutim, o endemskom tifusu u Kazahstanu se malo zna. Svrha ove studije bila je procijeniti prevalenciju IgG protutijela na R. typhi u populaciji južne regije Kazahstana. Metode. U istraživanje je uključeno ukupno 253 osoba (142 žena, 111 muškaraca) u dobi od 1 do 71 godine. Detekcija serumskih IgG protutijela na R. typhi provedena je imunoenzimskim ELISA testom. Rezultati. Ukupna seropozitivnost na R. typhi iznosila je 34,4%. Najveća seroprevalencija od 91,8% zabilježena je u regiji Turkestan. Najniža seropozitivnost od 6,1% otkrivena je u selu Lepsinsk, regija Almaty. Seroprevalencija se nije značajno razlikovala prema spolu. Seropozitivnost kod odraslih pojedinaca nije bila značajno povezana s dobi, ali pozitivni rezultati nisu otkriveni u dobnoj skupini djece mlađe od 14 godina. Zaključak. Dobiveni rezultati potvrđuju aktivnu cirkulaciju R. typhij u regijama Turkestan i Almaty u Kazahstanu. Podaci ukazuju na hitnu potrebu za daljnjim istraživanjima čiji je cilj procijeniti klinički učinak R. typhi u južnoj regiji Kazahstana. [ABSTRACT FROM AUTHOR]
