the red meat allergy syndrome in sweden.in the last decade, a novel type of food allergy presenting with severe allergic reactions several hours after consumption of red meat has been recognized. the allergic responses are due to ige antibodies directed against the carbohydrate epitope galactose-α-1,3-galactose (α-gal) found in mammalian meat. this review presents the red meat allergy syndrome in sweden, discusses the features of the immune response to carbohydrates, and highlights the presence of heat stable α-gal-containing proteins ...201627656352
inhibition of the endosymbiont "candidatus midichloria mitochondrii" during 16s rrna gene profiling reveals potential pathogens in ixodes ticks from australia.the australian paralysis tick (ixodes holocyclus) is of significant medical and veterinary importance as a cause of dermatological and neurological disease, yet there is currently limited information about the bacterial communities harboured by these ticks and the risk of infectious disease transmission to humans and domestic animals. ongoing controversy about the presence of borrelia burgdorferi sensu lato (the aetiological agent of lyme disease) in australia increases the need to accurately id ...201526108374
tick paralysis: development of a vaccine.the paralysis tick of australia, ixodes holocyclus, causes a severe toxicosis in domestic animals such as dogs and cats, livestock, and in some cases, humans. it is characterised by a rapidly ascending flaccid paralysis. the causative agent of the toxicosis is a neurotoxin(s) produced in the tick salivary glands. the current treatment for tick paralysis is in the form of a polyclonal dog antiserum. this antiserum treatment is expensive and effective only in the early stages of paralysis. the aim ...199910428629
interbreed differences in the efficacy of 1% deltamethrin pour-on to protect small livestock against infestation with ixodes rubicundus (acari:ixodidae).synthetic pyrethroid pour-on compounds have been developed for use on cattle but many are now also registered for the control of ectoparasites on small ruminants. the breed of small livestock has been known to influence the efficacy of various pour-ons and we hypothesized that differences in the duration of protection afforded by a synthetic pyrethroid pour-on against ticks on small livestock, would be greatest between hairy and woolly breeds. angora goats with mohair, dorper sheep with hairy wo ...19968792585
a comparison of ixodes rubicundus (acari: ixodidae) infestations on friesian and bonsmara cattle in south africa.this study was conducted to compare the relative resistance of crossbred bos indicus x b. taurus bonsmara and b. taurus friesian cattle to ixodes rubicundus (karoo paralysis tick) infestations. during periods of peak abundance of the ticks, friesian oxen harboured almost twice or more than twice as many ticks as either bonsmara oxen or cows. during periods of low tick abundance tick burdens on both cattle breeds were closely similar. it is envisaged that cattle can play an important role in an i ...19958575273
an evaluation of strategic and threshold control measures against the karoo paralysis tick, ixodes rubicundus (acari: ixodidae) in south africa.paralysis caused by feeding female ixodes rubicundus ticks is a major problem in large areas of south africa. as the life cycle of the tick extends over a period of 2 years, it was hypothesized that strategic treatment of sheep with an acaricide over a 2 year period, timed to kill most engorging females, should markedly lower the biotic potential of the tick. two flocks of sheep grazing in separate paddocks known to be infested with i. rubicundus were treated either strategically or on a thresho ...19957634969
cutaneous basophil-associated resistance to ectoparasites (ticks). i. transfer with immune serum or immune cells.immune resistance experiments were carried out in guinea-pigs employing two tick species that as adults are ectoparasites of cattle (ixodes holocyclus and rhipicephalus appendiculatus). these studies showed that susceptibility of non-immune guinea-pigs to infestation with tick larvae varies according to the species of tick and the strain of guinea-pig. with both tick species, greater than 90% acquired resistance was achieved in several guinea-pig strains. immune resistance was evident within a w ...19827061108
epidemiology and transmission of theileria sp of cattle in australia.theileria sp occurs in cattle in australia where boophilus microplus is not present. two species of ixodid ticks namely haemaphysalis longicornis and h. bancrofti have been implicated as natural vectors. experimental transmission was obtained with these two species but attempts to transmit the infection with b. microplus, ixodes holocyclus and amblyomma triguttatum were not successful. although calves born in the enzootic area may become infected before one-month-old most show evidence of infect ...19826818938
