ABSTRACT

Aim: A trial was conducted to assess the influence of parasitic load on the lambs reared under the intensive system, continuous grazing, and rotational grazing systems of management.

Materials and Methods: A total of thirty numbers of the undetermined breed of ewe lambs around 4-5 months of age were randomly selected and allotted to three treatment groups: T1 (intensive system - control), T2 (rotational grazing), and T3 (continuous grazing). The T1 group lambs were raised under a stall-fed system of management, the T2 group lambs were grazed under rotational grazing strategy in four paddocks of plot-A, while the T3 group lambs were continuously grazed in plot-B.

Results: At the end of the study, there was a highly significant difference (p=0.01) in the fortnightly strongyle egg count per gram (EPG) of feces among the lambs pertaining to the three treatment groups; the lambs in T3 had a higher strongyle EPG compared to T2 lambs. With regard to the overall reduction in EPG from the initial count, lambs under rotational grazing showed the maximum decrease of 54.52% compared to lambs under T3 (continuous grazing). There was a strong positive correlation noticed between the mean temperature of the day at each fortnight and the subsequent EPG at each fortnight with R2=0.87. There was a strong positive correlation noticed between mean FAMACHA® scores and the EPG with R2=0.84, R2=0.83, and R2=0.83 for T1, T2, and T3, respectively.

Conclusion: The grazing management with pasture rotation should be considered as a viable option for sustainable parasitic control in case of grazing-dependent livestock husbandry in India.

ABSTRACT

Aim: This study aimed to determine the prevalence rates of Mycobacterium infection in camel sera collected before slaughter and gross lesion tissue collected at postmortem (PM) using enzyme-linked immunosorbent assay (ELISA), bacteriological culture, and polymerase chain reaction (PCR). In addition, serum samples from humans who had occupational contact with camels were tested by ELISA and sputum sample by culture.

Materials and Methods: ELISA was performed on serum samples antemortem. In addition, bacteriological culture and PCR were conducted after PM. Tuberculosis infection was identified in humans who had contact with camels using ELISA for serum samples and culture for sputum samples.

Results: Tuberculous lesions were detected in 184 of 10,903 camels (1.7%). The ELISA results revealed that of the 184 examined camel serum samples, 124 (67.39%) were positive and all 20 camel serum samples that had no associated tuberculous lesions were negative. Moreover, only one of 48 (2.08%) human serum samples was positive by ELISA. Mycobacterial culture revealed 112 isolates from the 184 examined camel samples (60.87%), while human sputum sample cultures were all negative. PCR analysis identified the mpb70 gene in three of seven randomly tested samples.

Conclusion: Gene sequencing was performed on two samples and the sequences were submitted to the National Center for Biotechnology Information GenBank (accession numbers MF990289 and MG59479). A phylogenetic tree was constructed based on the partial DNA sequences of the mpb70 gene; the similarity between the isolates was 98.1%. The similarities between the two isolates and the standard strains of Mycobacterium bovis in GenBank were 98.1% and 100%, respectively. Further investigation on the antemortem detection of M. bovis infection in camels is needed to decrease public risk.

ABSTRACT

Aim: The objective of this research was to identify the parasite species found in the gastrointestinal tract and pancreas of Aceh cattle slaughtered in a Banda Aceh slaughterhouse using lactophenol and semichon carmine staining.

Materials and Methods: Each sample out of 50 samples of gastrointestinal tract and pancreas from Aceh cattle slaughtered in a Banda Aceh slaughterhouse was separated by organ. Each organ was examined for the presence of worm. Then, the parasitic worms found were subsequently collected and separated based on class and species, followed by staining using lactophenol and semichon carmine. The worms were then identified and their prevalence was determined.

Results: The results showed that three species of parasites were successfully identified, all belonging to the nematode class, namely, Oesophagostomum radiatum, Oesophagostomum columbianum, and Setaria labiatopapillosa with the prevalence of 12%, 10%, and 6%, respectively. In addition, there was one species of parasite from the trematode class, namely, Eurytrema pancreaticum with prevalence of 0.4%.

Conclusion: The nematode class worms, such as O. radiatum, O. columbianum, and S. labiatopapillosa, can be stained by lactophenol, while the trematode class worm such as E. pancreaticum can be stained by semichon's carmine.

ABSTRACT

Background and Aim: Fascioliasis is a zoonotic disease of public importance that affects animals and man. This study was aimed at assessing Fasciola infection among goats slaughtered in Port Harcourt metropolis.

Materials and Methods: A total of 323 gallbladder and fecal samples were collected from three different abattoirs (Mile 3, Rumuokwurusi, and Trans-Amadi) between September 2015 and June 2016 and analyzed using standard parasitological method.

Results: Of the 323 fecal samples, 20 (6.19%) were found to be positive for Fasciola egg. Mile 3 abattoir 17 (5.26%) had higher prevalence than Trans-Amadi abattoir 3 (0.93%) while Rumuokwurusi had no infection (Chi-square=0.11; p=0.001). Gallbladder infection was 5.57%. Trans-Amadi abattoir had the highest prevalence of 11 (3.41%) followed by Mile 3 abattoir 7 (2.17%) and Rumuokwurusi abattoir had none (Chi-square=0.91; p=0.339). Infection based on gender showed that 5.88% of female animals and 0.31% of males were ova positive. At Trans-Amadi, 0.93% of females against 0.0% of males were infected (p>0.05). At Mile 3, it was 4.95% of females against 0.31% of males (p=0.001). Rumuokwurusi abattoir had no infection. Gallbladder infection showed Trans-Amadi 2.79% of females and 0.62% of males; Mile 3, 2.17% of females and 0.0% of males and Rumuokwurusi had no infection.

Conclusion: Fasciola infection is prevalent in goats in Port Harcourt. The health implication of these findings is that humans are at risk as fascioliasis is a zoonotic disease. There is a need to intensify effort to create more awareness of the possible consequence of this infection.

ABSTRACT

Aim: This study aimed to investigate the prevalence and implication of extended-spectrum beta-lactamase (ESBL) producing and Class 1 integrons (int1) gene carriers Escherichia coli isolates that demonstrated multidrug resistance (MDR) phenotypes and was isolated from turkeys that suffered from respiratory manifestation.

Materials and Methods: A total of 120 freshly dead turkey poults that suffered from respiratory manifestations, with a history of treatment failure at Hefna, Belbis, Sharqia (Egypt) were sampled. From each bird lung and liver were aseptically collected and transported for laboratory investigations.

Results: Examination of samples collected from 120 freshly dead turkey poults revealed the isolation of coagulase-positive staphylococci, coagulase-negative staphylococci, Campylobacter spp., Salmonella spp., Proteusspp., Pseudomonas spp., Klebsiella spp., and E. coli with the prevalence rates of 12/120 (10%), 30/120 (35%), 17/120 (14.2%), 5/120 (4.1%), 17/120 (14.2%), 6/120 (5%), 7/120 (5.8%), and 18/120 (15%), respectively. E. coliisolates were subjected for serotyping and characterization, while the rest of isolates were preserved to be investigated later in further studies. Serogrouping of E. coli isolates revealed the identification of O119, O6, O8, and O169, while 1/18 isolate was untypable. Studying phenotypic antibiotic susceptibility profiles of isolates revealed that 18/18 (100%) of isolates demonstrated resistance against cefuroxime, tetracycline, and trimethoprim, 16/18 (88.9%) of isolates demonstrated resistance to amoxicillin/ clavulanic acid, enrofloxacin, and norfloxacin, 14/18 (77.8%) of isolates demonstrated resistance to doxycycline and ciprofloxacin, and 9/18 (50%) of isolates showed resistance to gentamycin. Double disk synergy test showed that 6/18 (33.3%), 8/18 (44.4%), and 13/18 (72.2%) of isolates demonstrated the phenotypic pattern of ESBL producers with cefepime, cefotaxime, and ceftriaxone, respectively. Genotypic attributes for beta-lactamase TEM gene and int1 gene were studied by reverse transcriptase-polymerase chain reaction and revealed that 17/18 (94.4%) of isolates were positive for both genes. Embryo lethality test indicated that the 18 studied E. coli isolates were considered primary pathogens.

Conclusion: The results revealed that 18/18 (100%) of E. coli isolates demonstrated MDR against three or more antibiotic groups, 9/18 (50%) of isolates showed extensive resistance against the nine tested chemotherapeutic agents from seven antibiotic groups. It is recommended to monitor the circulation of MDR and ESBL-producing pathogens in poultry production in a one health approach, as a preventive measure to mitigate the risk imposed on public health.

ABSTRACT

Aim: The study aimed to identify fatty acid synthase (FASN), LOC514211, and fat mass and obesity-associated (FTO) gene polymorphisms and to investigate their associations with milk traits in an Indonesian-Holstein dairy cow population.

Materials and Methods: A total of 100 Indonesian-Holstein cows consisting of 50 heads (0th generation; G0) and 50 heads of their daughters (1st generation; G1) were used. Polymerase chain reaction-restriction fragment length polymorphism was performed to genotype three single nucleotide polymorphisms: rs41919985 in the FASN gene, rs42688595 in the LOC514211 gene, and g.1371T>A in the FTO gene.

Results: FASN rs41919985 was associated with milk protein percentage (p<0 .05="" fto="" g.1371t="">A was associated with milk fat percentage (p<0 .05="" and="" any="" associated="" loc514211="" not="" p="" rs42688595="" trait="" was="" with="">0.05). Heterozygote variants showed a higher protein percentage for FASN and the highest fat percentage for FTO. These associations were consistent in the G0 and G1 populations.

Conclusion: Our results indicate that the milk protein and fat percentages can be improved by increasing the frequency of the AG genotype of FASN and the AT genotype of FTO, respectively.

ABSTRACT

Background and Aim: Dairy animals play an important role in the Indian economy. Knowledge of the occurrence pattern of long bone fractures in bovine may help in strategizing the possibilities of treatment and prognosis. This study aimed to find out the comparative occurrence pattern of fractures in cattle and buffaloes.

Materials and Methods: A total of 278 fractures of bovine (171 in cattle and 107 in buffaloes), presented to the Department of Veterinary Surgery and Radiology, Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, Punjab, India, during a study of 1 year, were investigated for the occurrence pattern, in relation to species, age, body weight, gender, bone involved, type of fracture (closed or open), and the presentation of bovine as standing or in recumbent state.

Results: The overall hospital occurrence of fractures in bovine was 4.24% and most of the fractures resulted from slipping and falling on hard floor. Of 278 fractures, the majority (90.28%) involved long bones (n=251; 103 buffaloes and 148 cattle). Forelimb fractures were recorded more common in buffaloes (64.08%), whereas the cattle suffered more of hind limb fractures (60.23%). Cattle also included 11 cases of bilateral fractures of metacarpal (n=3), tibia (n=1), radius and ulna (n=1), and mandible (n=6). Fracture of olecranon constituted 6.83% (n=19) and majority (n=15) were in buffaloes. The cattle had higher percent of open fractures (54.38%) as compared to that in buffaloes (17.76%). Marginally higher percentage of cattle (33.33%) suffering from fracture were recumbent as compared to buffaloes (23.36%) and femur fractures were found to be a leading cause of recumbency (100% in cattle and 75.00% in buffaloes).

Conclusion: Species-specific differences in the occurrence pattern of fractures exist among cattle and buffaloes. Cattle are found to be more susceptible (1.5 times) to fractures as compared to buffaloes. The buffaloes are vulnerable to forelimb fractures while the cattle to the hind limb. As compared to forelimb, long bone fractures of hind limb are more commonly associated with recumbency in bovine. Cattle are more prone to mandible fractures and the open fractures of long bones as compared to buffaloes.
