high risk for human exposure to rift valley fever virus in communities living along livestock movement routes: a cross-sectional survey in kenya.multiple outbreaks of rift valley fever (rvf) with devastating effects have occurred in east africa. these outbreaks cause disease in both livestock and humans and affect poor households most severely. communities living in areas practicing nomadic livestock movement may be at higher risk of infection. this study sought to i) determine the human exposure to rift valley fever virus (rvfv) in populations living within nomadic animal movement routes in kenya; and ii) identify risk factors for rvfv ...202032084127
immersion foot syndrome in 6 equids exposed to hurricane floodwaters.prolonged exposure to water, known as immersion foot syndrome in humans, is a phenomenon first described in soldiers during world war i and characterized by dermal ischemic necrosis. in this report, we describe the pathologic findings of a condition resembling immersion foot syndrome in 5 horses and 1 donkey with prolonged floodwater exposure during hurricane harvey. at necropsy, all animals had dermal defects ventral to a sharply demarcated "water line" along the lateral trunk. in 5 animals, hi ...202032081085
the molecular epidemiology and phylogeny of torque teno virus (ttv) in jordan.torque teno virus (ttv) is the most common component of the human blood virobiota. little is known, however, about the prevalence of ttv in humans and the most common farm domesticates in jordan, or the history and modality of ttv transmission across species lines. we therefore tested sera from 396 jordanians and 171 farm animals for the presence of ttv dna using nested 5'-utr-pcr. we then performed phylogenetic, ordination and evolutionary diversity analyses on detected dna sequences. we detect ...202032023916
efficacy of fda-approved anti-inflammatory drugs against venezuelan equine encephalitis virus infection.venezuelan equine encephalitis virus (veev) is a category b select agent pathogen that can be aerosolized. infections in murine models and humans can advance to an encephalitic phenotype which may result in long-term neurological complications or death. no specific fda-approved treatments or vaccines are available for the treatment or prevention of veev infection. neurotropic viral infections have two damaging components: neuronal death caused by viral replication, and damage from the subsequent ...201931842327
detection of hepatitis e virus genotypes 3 and 4 in donkeys in northern china.hepatitis e virus (hev) is the causative agent of acute self-limiting hepatitis in humans in developing countries. hepatitis e virus rna was first detected in donkeys in spain, but little is known about the possible presence of hev in donkeys in china.202031746470
potential dual expansion of domesticated donkeys revealed by worldwide analysis on mitochondrial sequences.molecular studies on donkey mitochondrial sequences have clearly defined two distinct maternal lineages involved in domestication. however, domestication histories of these two lineages remain enigmatic. we therefore compared several population characteristics between these two lineages based on global sampling, which included 171 sequences obtained in this study (including middle asian, east asian, and african samples) plus 536 published sequences (including european, asian, and african samples ...202031709786
serological evidence of leptospirosis in iran; a systematic review and meta-analysis.leptospirosis is a neglected infectious zoonotic disease that affects domestic animals and wildlife as well as humans. although leptospirosis is known as an endemic disease in iran, there is no accurate information on the overall prevalence of this disease in humans and animals. the aim of this systematic review and meta-analysis was to estimate the seroprevalence of leptospirosis among human and domestic and wild animals in iran. a systematic review of english and persian articles (since 1998 t ...202031698052
a study regarding bovine enterovirus type 1 infection in domestic animals and humans: an evaluation from the zoonotic aspect.bovine enteroviruses (bev) are members of enterovirus genus of the family picornaviridae. bev1 has a broad host spectrum, including humans. the virus usually causes subclinical infection, but fatal/severe cases have also been reported in different animal species. there is quite limited data regarding bev1 in humans. the purpose of this study is to investigate human infection and to identify possible risk factors for viral exposure. for this purpose, blood serum samples (n=1,526) were collected f ...201931564680
cloning and expression analysis of the follicle-stimulating hormone receptor (fshr) gene in the reproductive axis of female yaks (bos grunniens).follicle-stimulating hormone receptor (fshr) plays a central role in promoting follicle maturation through the follicle-stimulating hormone (fsh)-mediated camp pathway in animals. the objectives of the present study were to clone the fshr gene of yaks (bos grunniens) and compare differences in fshr mrna expression in the reproductive axis between yaks and cattle. hypothalamus, anterior pituitary, oviduct, ovary, and uterus tissue samples were collected from adult female yaks (n = 5) and cattle ( ...202031479928

a novel 13-plex str typing system for individual identification and parentage testing of donkeys (equus asinus).previous studies investigating donkey parentage and genetic diversity used horse-specific multiplex systems. however, several mis-allele and null-allele issues were found with some of the horse primers when used in donkeys. in 2017, the international society for animal genetics (isag) recommended 13 dinucleotide short tandem repeats (strs) (aht4, asb23, hms2, hms3, hms6, hms7, hms18, htg7, htg10, tky297, tky312, tky337 and tky343) as a core panel that should be used to identify individuals and t ...202031398262
a molecular analysis of sand fly blood meals in a visceral leishmaniasis endemic region of northwestern ethiopia reveals a complex host-vector system.visceral leishmaniasis (vl, or "kala-azar") is a major cause of disability and death, especially in east africa. its vectors, sand flies (diptera: psychodidae: phlebotominae), are poorly controlled and guarded against in these regions, owing in part to a lack of understanding about their feeding behavior.201931384683
leptospirosis, one neglected disease in rural senegal.a serological study was carried out in two senegalese villages located in the sine-saloum region in order to estimate the presence of anti-leptospiral antibodies in humans and animals, and to identify the predominant serogroups. seven hundred and forty-nine serum samples were collected from humans (n = 545), dogs (n = 33), donkeys (n = 20), goats (n = 52), sheep (n = 43) and n'dama cattle (n = 56), all originated from dielmo and ndiop villages. all samples were tested for different serovars of p ...201931342674
