Cryptosporidiosis is an important parasitic infection of cattle, buffaloes, goats, sheep, horses, cats, human beings and other vertebrates. Prevalence of Cryptosporidiosis in selected animals and human beings carried out on the basis of microscopic examination and polymerase chain reaction (PCR). Percent prevalence of Cryptosporidiosis determined on the basis of conventional identification method was highest in calves (23.1) followed by cattle (10.5) and buffaloes (8.47). Percent prevalence of Cryptosporidiosis in calves, cattle and buffaloes was higher at Government dairy farm (38.33, 20.55 and 16.66) followed by Gawala colonies (26.1, 12.77 and 9.44), Military dairy farm (18.3, 6.11 and 4.44) and then House hold dairies (10, 3.88 and 3.34). Percent prevalence recorded in calves having age less than six months was higher (26.45) than those with 7-12 months of age (16.6). Percent prevalence of Cryptosporidiosis in cattle having age of 2-3 years was higher than those cattle having 3-7 years of age. Similarly, infection rate was higher in buffaloes with 2-3 years age (11.8) than 3-7 years (9.8). Cryptosporidiosis percent prevalence recorded in female calves was higher (24.04) than male calves (18.2). Percent prevalence of Cryptosporidium oocysts observed in feces of male cattle was little higher (11.25) than female cattle (10.4). Cryptosporidiosis percent prevalence recorded in female buffaloes was higher (13.3) than male buffaloes (8.3).
The data was analyzed monthly for the purpose to trace out the specific period of the year having the highest prevalence rate of Cryptosporidium infection. The highest percent prevalence of Cryptosporidiosis recorded in fecal samples of calves was during summer (27.5) followed by autumn (25.8), spring (20.3) and the lowest in winter season (14.5). Overall the highest percent prevalence of Cryptosporidiosis in cattle recorded was during summer (15), followed by spring/autumn (10.88) and the lowest in winter (6.6%). The highest percent prevalence of Cryptosporidiosis recorded in buffaloes was during summer (12) followed by autumn (20), spring (7.5) and the lowest in winter season (4.5). In human beings patients suffering from diarrhea were examined by microscopy and percent prevalence calculated was 40 in present study.
Molecular percent prevalence rate determined was 12.22 in cattle. Percent prevalence recorded using PCR was the highest at Government dairy farm (22.7), followed by Gawala colonies (14.41), Military dairy farm (7.7) and the lowest at House hold dairies (5). The highest season wise percent molecular prevalence was observed during summer (16.6) followed by autumn/spring (13.3), the lowest in winter (7.7). The higher molecular percent prevalence in young cattle (2-3 years) was higher (23.7) than those having age between 3-7 years (10.7). Molecular percent prevalence of Cryptosporidiosis in selected cattle was lower in females (13.6) than males (15).
The efficacy of albendazole observed was 43.05, 58.7 and 64.6 percents on 13th, 20th and 27th day post treatment. The efficacy of albendazole determined on this dose was 34.8, 57.1 and 62.9 percents on days 13, 20 and 27 post therapy. Efficacy of drug calculated on days 13, 20 and 27 was 32.8, 53.3 and 56.6 percent, respectively. Percent efficacy of used drug was 55.04, 68.5 and 79.4 on days 13, 20 and 27 post treatment, respectively. At 50mg/kg body weight dose rate of paromomycin significant decrease in OPG count was recorded from 6th day post treatment and onward (P<0.05). On days 13, 20 and 27 percent efficacy of used drug determined was 48.1, 65 and 69, respectively.
