We conducted serological surveys for Coxiella burnetii in archived sera from patients that visited a rural clinic in western Kenya from 2007 to 2008 and in cattle, sheep, and goats from the same area in 2009. We also conducted serological and polymerase chain reaction-based surveillance for the pathogen in 2009-2010, in human patients with acute lower respiratory illness, in ruminants following parturition, and in ticks collected from ruminants and domestic dogs. The IgG antibodies against C. burnetii were detected in 30.9% (N = 246) of archived patient sera and in 28.3% (N = 463) of cattle, 32.0% (N = 378) of goats, and 18.2% (N = 159) of sheep surveyed. Four of 135 (3%) patients with acute lower respiratory illness showed seroconversion to C. burnetii. The pathogen was detected by polymerase chain reaction in specimens collected from three of six small ruminants that gave birth within the preceding 24 hours, and in five of 10 pools (50%) of Haemaphysalis leachi ticks collected from domestic dogs.

    • "Kenya (Knobel et al. 2013), we utilized complementary methodologies to document seroprevalence in four of the county's livestock species and evaluate local knowledge, attitudes, and practices concerning the disease. Caused by the bacterial pathogen Coxiella burnetii, Q fever has multiple transmission modes and occurs globally in both humans and animals. "

    ABSTRACT: Two hundred fourteen serosamples were collected from four livestock species across five ranches in Laikipia County, Kenya. Serological analysis for Coxiella burnetii (the causative agent for Q fever) showed a distinct seroprevalence gradient: the lowest in cattle, higher in sheep and goats, and the highest in camels. Laikipia-wide aerial counts show a recent increase in the camel population. One hundred fifty-five stakeholder interviews revealed concern among veterinary, medical, ranching, and conservation professionals about Q fever. Local pastoralists and persons employed as livestock keepers, in contrast, revealed no knowledge of the disease. This work raises questions about emerging Q fever risk in Laikipia County and offers a framework for further integrative disease research in East African mixed-use systems.

    ABSTRACT: Q fever is a zoonotic disease, caused by the obligate intracellular bacterium Coxiella burnetii. Between 2007 and 2010, Q fever has been a major public health concern in the Netherlands, with almost 3500 human cases reported and dairy goats considered to be the most probable source. At the end of 2009, the Dutch government decided to cull all pregnant dairy sheep and dairy goats based on bulk tank milk C. burnetii positive farms, aiming to preventing shedding and to reducing environmental contamination. On bulk tank milk C. burnetii PCR positive farms, a life-time breeding ban was implemented for all remaining non-pregnant small ruminants. This study describes test results on a bulk tank milk C. burnetii PCR positive dairy goat farm on which all goats had been vaccinated against Q fever with an inactivated phase one vaccine since 2008. All pregnant dairy goats of this farm were culled in 2010, after which bulk tank milk was negative in the C. burnetii PCR. One year later, however, this farm became bulk tank milk C. burnetii PCR positive again. From all lactating animals on the farm (n = 350), individual milk samples were collected and tested using a commercial real-time PCR assay. Individual milk samples from five dairy goats appeared to be C. burnetii PCR positive. These positive goats had been born on the farm between 2002 and 2006. At postmortem examination, out of 33 mostly tissue samples per animal, only milk and mammary tissue samples were C. burnetii PCR positive. Moreover, immunohistochemical examination did not reveal the source of C. burnetii. After culling of these C. burnetii PCR milk positive animals, the bulk tank milk remained negative in C. burnetii PCR until the end of the observation period. The results indicate that vaccination of Q fever infected dairy goat farms does not completely prevent intermittent shedding of C. burnetii in probably previously infected goats. Further research is needed to investigate how and where C. burnetii multiplies in such intermittently shedding animals.

    ABSTRACT: For most rural households in sub-Saharan Africa, healthy livestock play a key role in averting the burden associated with zoonotic diseases, and in meeting household nutritional and socio-economic needs. However, there is limited understanding of the complex nutritional, socio-economic, and zoonotic pathways that link livestock health to human health and welfare. Here we describe a platform for integrated human health, animal health and economic welfare analysis designed to address this challenge. We provide baseline epidemiological data on disease syndromes in humans and the animals they keep, and provide examples of relationships between human health, animal health and household socio-economic status.
