clinical and laboratory characteristics, epidemiology, and outcomes of murine typhus: a systematic review.	murine or endemic typhus, a febrile disease caused by rickettsia typhi, is often misdiagnosed due to its non-specific presentation. we sought to evaluate all available evidence in the literature regarding the clinical and laboratory manifestations, epidemiological characteristics, and outcomes of murine typhus. pubmed was searched for all articles providing available data. in an effort to incorporate contemporary data, only studies from 1980 were included. thirty-three case series including 2074 ...	2017	27983969
serological evidence of exposure to rickettsia felis and rickettsia typhi in australian veterinarians.	rickettsia felis and rickettsia typhi are emerging arthropod-borne zoonoses causing fever and flu-like symptoms. seroprevalence and risk factors associated with exposure to these organisms was explored in australian veterinarians.	2017	28285586
molecular and serological evidence of flea-associated typhus group and spotted fever group rickettsial infections in madagascar.	rickettsiae are obligate intracellular bacteria responsible for many febrile syndromes around the world, including in sub-saharan africa. vectors of these pathogens include ticks, lice, mites and fleas. in order to assess exposure to flea-associated rickettsia species in madagascar, human and small mammal samples from an urban and a rural area, and their associated fleas were tested.	2017	28259176
limited evidence for rickettsia felis as a cause of zoonotic flea-borne rickettsiosis in southern california.	over 90% of human flea-borne rickettsioses cases in california are reported from suburban communities of los angeles and orange counties and are presumed to be associated with either rickettsia typhi or rickettsia felis infection. ctenocephalides felis (bouché) is considered the principal vector for both rickettsiae, and r. felis has largely replaced r. typhi as the presumptive etiologic agent based on the widespread incidence of r. felis in cat flea populations. however, with no evidence to con ...	2017	28082625
survey for rickettsiae within fleas of great gerbils, almaty oblast, kazakhstan.	little is known of the endemicity of flea-borne rickettsiae in kazakhstan. thus, a survey for rickettsiae within great gerbil fleas was conducted in almaty oblast. high prevalence of rickettsia asembonensis was detected among xenopsylla gerbilli, demonstrating that flea-borne rickettsiae are endemic to southeastern kazakhstan. interestingly, no rickettsia typhi were detected in these same fleas.	2017	27992288
rickettsiae and rickettsial diseases in croatia: implications for travel medicine.	to review the current state of knowledge concerning rickettsiae and rickettsioses in croatia and to discuss their implications for travellers.	2017	27404664
acute febrile illness and complications due to murine typhus, texas, usa1,2.	murine typhus occurs relatively commonly in southern texas, as well as in california. we reviewed records of 90 adults and children in whom murine typhus was diagnosed during a 3-year period in 2 hospitals in southern texas, usa. most patients lacked notable comorbidities; all were immunocompetent. initial signs and symptoms included fever (99%), malaise (82%), headache (77%), fatigue (70%), myalgias (68%), and rash (39%). complications, often severe, in 28% of patients included bronchiolitis, p ...	2017	28726607
direct evidence of rickettsia typhi infection in rhipicephalus sanguineus ticks and their canine hosts.	murine typhus is a rickettsiosis caused by rickettsia typhi, whose transmission is carried out by rat fleas in urban settlements as classically known, but it also has been related to cat fleas in a sub-urban alternative cycle that has been suggested by recent reports. these studies remarks that in addition to rats, other animals like cats, opossums and dogs could be implied in the transmission of rickettsia typhi as infected fleas obtained from serologically positive animals have been detected i ...	2017	28652984
fatal flea-borne typhus in texas: a retrospective case series, 1985-2015.	abstractflea-borne (murine) typhus is a global rickettsiosis caused by rickettsia typhi. although flea-borne typhus is no longer nationally notifiable, cases are reported for surveillance purposes in a few u.s. states. the infection is typically self-limiting, but may be severe or life-threatening in some patients. we performed a retrospective review of confirmed or probable cases of fatal flea-borne typhus reported to the texas department of state health services during 1985-2015. when availabl ...	2017	28500797
first detection of rickettsia typhi and rickettsia felis in fleas collected from client-owned companion animals in the southern great plains.	flea-borne rickettsiosis occurs worldwide and includes a number of pathogens, namely, rickettsia typhi and rickettsia felis. most studies in the united states have occurred in southern texas and california where flea-borne rickettsiosis is endemic, resulting in a lack of information from other regions of the country. between march and august 2016, 222 fleas were collected from 52 client-owned dogs and cats in two urban areas in oklahoma. fleas were identified using morphological characteristics ...	2017	28399210
anaplasma, ehrlichia and rickettsia species infections in cats: european guidelines from the abcd on prevention and management	anaplasma species, ehrlichia species and rickettsia species are vector-borne pathogens infecting a wide variety of mammals, but causing disease in very few of them. infection in cats: anaplasma phagocytophilum is the most important feline pathogen among these rickettsial organisms, and coinfections are possible. little information is available on the pathogenesis of these agents in cats. clinical signs are usually reported soon after tick infestation. they are mostly non-specific, consisting of ...	2017	28438088
