| the prevalence of toxocara species ova in backyards and gardens of baltimore, maryland. | toxocara species ova were found in 16 of 146 (11 per cent) soil samples collected from backyards and gardens of private residences within baltimore city. the recovery rate of parasite ova was similar for households regardless of their grouping by pet ownership characteristics or the presence of visible animal feces. the findings demonstrate the common occurrence of these eggs in locations likely to be important in the transmission of visceral larva migrans. | 1985 | 4025663 |
| rabies in the united states and canada, 1983. | primarily as a result of organized canine rabies vaccination, leash laws, and other preventive procedures aimed at the canine population, the number of rabid dogs decreased markedly in the last thirty years (figure 10). this decrease was accompanied by a similar marked reduction in human rabies (table 2, figure 11). as domestic animal rabies declined, rabies in wildlife increased. since 1958 the number of cases of rabid wildlife surpassed domestic rabies cases, and today they account for over 85 ... | 1985 | 3932839 |
