“…In addition, calf gender had no significant effect on the infection. However, the findings of the current study do not support previous researches [36,42,47] that recorded higher prevalence rates of intestinal parasites in males than in females. Similarly, Priti et al [44], Rehman et al [12], and Jahanzaib et al [48] recorded a higher prevalence of infections in female cattle and buffalos than in males.…”

“…Herein, the most common parasites found in calves were Eimeria species, B. sulcata , Cryptosporidium species, and T. vitulorum . These results are in agreement with those obtained by El-sherif and Aboelhadid [35], Reberio et al [36], GÖZ et al [32], and Ramadan et al [34].…”

“…T. vitulorum was a cause of diarrhea in young calves with prevalence rates ranging from 12.24% to 23.80% in cattle and buffalo calves, respectively, for both ages. These findings are in accordance with data published by Riberio, et al [36] and Ramadan et al [34], who stated that T. vitulorum was the most helminthic pathogen in diarrheic buffalo calves (17.2%), while its prevalence rate was 12% in cattle calves in Munofyia province, Egypt. This could be partially due to the existence of several routes of transmission, such as trans-placental and trans-mammary transmission or ingestion of larvated eggs.…”

“…These findings are in line with those reported by El-sherif and Aboelhadid [35] in Egypt (10.50%) and Heidari et al [37] in Iran (8.25%). In this respect, Reberio et al [36] and GÖZ et al [32] reported that the most common parasite in neonatal suckling calves was Eimeria species. Furthermore, different prevalence rates of Eimeria species were reported in different regions of the same country (Turkey), for example by Yüksekova-Hakkari (89.13%) [38] and Yüzüncü Yıl (69.8%) [39].…”

The association between parasite isolates, including Buxtonella sulcata, in suckling and post-weaning calves and diarrhea was studied with the aim to control diarrhea caused by B. sulcata. A total of 1100 diarrheic fecal samples were collected from 609 suckling calves and 491 post-weaning calves with diarrhea. Salt floatation and modified Ziehl–Neelsen techniques were applied for the microscopic examination of the presence or absence of parasite eggs and oocysts/cysts. The microscopic findings revealed that 20.36% of the calves had parasitic diarrhea, with a prevalence rate of 19.54% in suckling calves and 21.38% in post-weaning calves. The most frequently detected parasites according to morphological characters were Eimeria species, Buxtonella sulcata, Toxocara vitulorum, Cryptosporidium species, and Moneizia species. In suckling calves, Eimeria species, B. sulcata, and T. vitulorum had the highest prevalence rates of infection, corresponding to about 37.14%, 32.86%, and 20.00%, respectively. However, in post-weaning calves, B. sulcata infection was more prevalent (30.15%) than infections with Eimeria species and T. vitulorum. The highest parasite score density was found in multiple infections with B. sulcata, Eimeria species, and T. vitulorum; however, the score density of B. sulcata when present alone in the fecal specimens was higher than in specimens co-infected with other parasites. The risk factors affecting the prevalence rate of parasitic diarrhea, such as sex, season, housing system, and feed stuff, are discussed. Concerning the treatment of diarrhea caused by B. sulcata in post-weaning cattle calves, 20 calves were divided into 4 equal groups. Group A was given sulphadimidine sodium (1.0 g/10 kg body weight) and metronidazole (500 mg/40 kg body weight); group B was treated with oxytetracycline hydrochloride (500 mg/45 Kg of body weight) and metronidazole (500 mg/40 kg body weight); group C was daily administered garlizine (allicin), 2 g/ L in drinking water; group D was the untreated control group. All medications were administered orally for four successive days. The results showed that the cyst count was significantly lower in the drug-treated groups, and the metronidazole + oxytetracycline hydrochloride and metronidazole + sulphadimidine combinations achieved 98.77% and 96.44% efficacy, respectively. Garlizine had 72.22% efficacy. Intriguingly, B. sulcata infection was associated with other parasitic infections, but B. sulcata mono-infection was the most common cause of diarrhea. Moreover, the combinations of oxytetracycline hydrochloride or sulphadimidine with metronidazole are recommended to control buxtonellosis in calves. Further studies are recommended to investigate the bacterial, viral, and fungal infections associated with B. sulcata infection.

Estimate of size and total number of neurons in superior cervical ganglion of rat, capybara and horse

2004

The superior (cranial) cervical ganglion was investigated by light microscopy in adult rats, capybaras (Hydrochaeris hydrochaeris) and horses. The ganglia were vascularly perfused, embedded in resin and cut into semi-thin sections. An unbiased stereological procedure (disector method) was used to estimate ganglion neuron size, total number of ganglion neurons, neuronal density. The volume of the ganglion was 0.5 mm3 in rats, 226 mm3 in capybaras and 412 mm3 in horses. The total number of neurons per ganglion was 18,800, 1,520,000 and 3,390,000 and the number of neurons per cubic millimetre was 36,700, 7,000 and 8,250 in rats, capybaras and horses, respectively. The average neuronal size (area of the largest sectional profile of a neuron) was 358, 982 and 800 microm2, and the percentage of volume occupied by neurons was 33, 21 and 17% in rats, capybaras and horses, respectively. When comparing the three species (average body weight: 200 g, 40 kg and 200 kg), most of the neuronal quantitative parameters change in line with the variation of body weight. However, the average neuronal size in the capybara deviates from this pattern in being larger than that of in the horse. The rat presented great interindividual variability in all the neuronal parameters. From the data in the literature and our new findings in the capybara and horse, we conclude that some correlations exist between average size of neurons and body size and between total number of neurons and body size. However, these correlations are only approximate and are based on averaged parameters for large populations of neurons: they are less likely to be valid if one considers a single quantitative parameter. Several quantitative features of the nervous tissue have to be taken into account together, rather than individually, when evolutionary trends related to size are considered.
