“…The shorter PP in this present study may suggest that the T. brucei isolates used are more virulent thereby increasing its ability to establish infection in the bucks. The clinical signs of rough hair coat, alopecia, pyrexia, ocular discharge epistaxis and progressive anemia are consistent with findings in earlier studies of trypanosomosis (2,3,5,31,32).…”

“…At this stage (day 29) the parasite is absent in the blood circulation whereas the genital organs are massively invaded. Moreover, the persistent fluctuation in temperature could be a contributory factor as observed in earlier studies (3). The seminiferous tubules are temperature sensitive and their activities can be altered by minor temperature fluctuations.…”

“…Glucose is the major source of energy utilized for motility and maturation by spermatozoa, particularly along the epididymis (33). Trypanosomes have been reported to utilize glucose for their metabolic processes during the peak of parasitemia (3,34). The depletion in the epididymal sperm reserves in this present study occurred 3 days after the second peak of parasitemia.…”

“…Trypanosomosis is a wasting disease of animals that is widespread in tropical areas of Africa and South America (1). It is characterized by anemia, intermittent fever, anorexia, respiratory distress, lacrimation, nasal discharge, edema, enlarged lymph nodes, central nervous system disorders, corneal opacity, reproductive disorders and death in severe cases (2,3,4,5,6,7). The disease is caused by blood parasites of the family Trypanosomatidae and genus Trypanosoma (8).…”

This study was designed to determine the progressive pathological changes in the testis and epididymis of rabbit bucks experimentally infected with Trypanosoma brucei brucei (T. brucei). Fifteen local rabbit bucks were divided into 2 groups comprising 8 bucks in group A and 7 bucks in group B. Bucks in group A were infected intraperitoneally with approximately 1.0x106 of T. brucei while bucks in group B served as the uninfected control. The bucks were closely monitored for clinical signs of trypanosomosis from the time of infection till the end of the study. One buck from each group was humanely sacrificed on days 9, 19, 29 and 38 post-infection (pi) and its testis and epididymis were examined for pathological changes. At post mortem, no gross lesions were observed in the infected bucks except for adhesion of the testis and epididymis to the scrotum on days 29 and 38 pi. There were no histological changes in the testis and epididymis of the infected buck sacrificed on day 9 pi apart from mild depletion of the epididymal sperm reserve. The buck infected on day 19 pi had moderate testicular degeneration but the epididymis was devoid of sperm reserve. Severe testicular and epididymal degeneration was observed in the buck on days 29 and 38 pi. The testis and epididymis of bucks from the control group were normal with evidence of spermatogenic activities and full epididymal sperm reserve throughout. The study shows that infected bucks were unfit for breeding from day 19 pi.

“…One milliliters of blood were collected from the jugular vein every 4 days into sample bottles containing EDTA. This blood was used to estimate parasitemia Parasitemia was determined using wet mount and hematocrit centrifugation techniques for the detection of trypanosomes as described by Adeyeye et al [16] and Desquesnes et al [17]. The number of parasites was estimated following the method described by Herbert and Lumbsden [18].…”

Haematological profiles were determined in Yankasa sheep experimentally infected with Trypanosoma evansi (T. evansi) and treated with diaminazene aceturate (berenil ® ). A total of 30 animals were divided into 6 groups (A to F) (n=5). Animals from each group were either uninfected or infected with T. evansi, and treated with Berenil ® . Infection of the infected groups (A, C and E) was done via intravenous inoculation of T. evansi, while the infected group C and E were treated with berenil ® at 3.5 and 7 mg/kg BW, respectively, by day 16 post infection (PI). The infected groups had pre-patent period of 8 days, with similar levels of parasitaemia (4.7 ± 0.27). In group A, the mean parasite count rose significantly (P < 0.05) to 72.8 ± 1.07 by day 12 PI and continue to a peak
