Molecular epidemiology and antibiotic resistance pattern of Enteropathogenic Escherichia coli isolated from bovines and their handlers in Jammu, India
2014
Majueeb U Rehman | Mohd Rashid | Javeed Ahmad Sheikh | Mohd Altaf Bhat
The study was aimed to investigate the molecular epidemiology and antibiotic resistance pattern of Enteropathogenic Escherichia coli (EPEC) in bovines and their handlers in Jammu, India. A total of 173 samples comprising of 103 fecal samples from bovines (60 from cattle and 43 from buffaloes), 28 stools and 42 fingertip rinses from bovine handlers were collected during August 2011 to March 2012. The isolated 126 E. coli strains (86 from bovines and 40 from handlers) belonged to 25 different serogroups in addition to rough and untypeable strains. Using multiplex polymerase chain reaction, four EPEC strains were isolated; two each from bovines and their handlers, of which two possessed the hemolysin (hlyA) gene. The prevalence of EPEC was recorded as 1.66% (n=1/60) in cattle, 2.32% (n=1/43) in buffaloes, and 2.85% (n=2/70) in their handlers. Antibiogram studies with the EPEC revealed the presence of multi-drug resistant E. coli. The isolates were mostly resistant to Amikacin, Amoxicillin, Cefixime and Streptomycin, and sensitive to Chloramphenicol. This study indicates that bovines as well as their handlers in Jammu region harbor EPEC, many of which being multi-drug resistant and carrying the hemolysin gene could be of high pathogenic potential for humans.

Chappidi Venkata Seshaiah | Y. Ramana Reddy | S. Jagadeeswara Rao | M. Srivani
The in vitro gas technique was used to predict the efficiency of sweet sorghum (Sorghum bicolor L. Moench) bagasse (SSB) based total mixed ration comprising different ratios of roughage and concentrate, with the objective of identifying optimum ratio for feeding buffaloes. Eight rations were prepared with roughage to concentrate ratio of 100:0 to 30:70. Significantly (p<0.01) higher in vitro gas production volume (mL) at 24 h incubation were recorded for the rations with roughage (R) to concentrate (C) ratio of 60R:40C to 30R:70C as compared to other rations. Whereas, in vitro organic matter digestibility (IVOMD) was significantly (p<0.01) higher for the rations 70R:30C to 30R:70C as compared to other rations. Metabolisable energy (ME) and truly digestible organic matter (TDOM) were significantly (p<0.01) higher for the rations 90R:10C to 30R:70C as compared to sole SSB. The rations from 90R:10C to 30R:70C were significantly (p<0.01) higher in partitioning factor (PF), microbial biomass production (MBP) and efficiency of microbial biomass production (EMBP) as compared to sole SSB. However, the PF was not significant among rations 50R:50C, 40R:60C and 30R:70C. Therefore, the present study suggested that SSB can be included in total mixed ration of buffaloes at 50-60% for economic ruminant livestock production.

2014
Khan, A | Gazi, MA | Bashir, S | Dumralia, DM | Bagate, MS
Two cases with a history of cessation of feces for 2 weeks, depression, lethargy and anorexia in two different dogs; a Labrador male and a Doberman female, were presented. On physical examination, abdominal distension along with intense pain was observed. Blood samples were collected from the dogs for hematological and biochemical analyses. The examination revealed an increased percentage of packed cell volume (PCV). By radiological examina-tion, radiopaque material was seen in the large intes-tinal tract. The condition was suggestive of fecolith. The cases were managed by means of non-surgical management. Through an 11-day long medicinal treatment, the dogs recovered uneventfully.

Najibullah Mohamand | Lakshmanasami Gunaseelan | Bharathy Sukumar | Kannan Porteen
In this study, milk samples were collected from 109 dairy cows to detect antibodies against Brucella (B.) using Milk Ring Test (MRT). Overall, 18.35% (n=20/109) of the milk samples were positive by MRT. The cows were divided into three groups based on lactation number viz., 1st, 2nd to 4th and ≥5th lactations; the prevalence of brucellosis in the groups were found to be 0.92% (n=1/109), 15.60% (n=17/109) and 1.83% (n=2/109), respectively. Considering simplicity and cost effectiveness, the MRT can be used for the preliminary screening of B. abortus infection especially in single cow herds.

Ahmed Tunio | Abu Jalila | Goh Yong Meng | Intan Shameha
This study was conducted to assess the healing of transverse ulna fracture when fixed with external skeletal fixation (ESF) in pigeon. Ulna fracture was created under Isoflurane anesthesia in pigeons. A total of 12 pigeons were used in this study, and they were divided into three equal groups: Group-1, Group-2 and Group-3. The birds of the three groups were sacrificed at 3, 6, and 12 weeks after successful fracture surgery. It was found that bone union occurred between three and six weeks in all groups. Bone alignment, and callus remodeling were evident at 12 weeks (p<0.05) post fracture fixation. There were no radiographic evidence of callus remodeling in any bird at 3 and 6 weeks post-surgery. The radiographic observations of fracture healing in this study have confirmed that ESF fixation is an effective method to stabilize ulna fracture in pigeons and results in faster fracture healing.

Mahendra Pal | Weldegebrial Gebrezabiher | Md. Tanvir Rahman
According to the WHO- “Health is a state of complete physical, mental and social well-being and not merely an absence of disease or infirmity”. The good health is the fundamental right of all the people on earth. The concept of ‘One Medicine’ coined by Calvin W. Schwabe evolves towards ’One Health’ which comprises collaborative efforts of multiple disciplines to achieve perfect health of people, animals, and our environment. ‘One Health’ deals with the challenges at the intersection of animal, human and environment health including the infectious diseases, the global food crises, and climate change due to global warming. The cordial and active association of various disciplines such as medicine, veterinary, public health, environment, wildlife, ecology, and food hygiene is highly emphasized in order to achieve the goal of ‘One Health’. This mini-review describes brief history of ‘one health’, the roles of veterinary, medical and environmental professionals, and developing collaboration with various concern professionals to achieve ‘one health’. In addition, the selected achievements of ‘one health’ in the past 10 years have been described along with the challenges ahead for the successful implementation of such concept.

This study was conducted to assess the influence of chromium on the carcass traits in crossbred (Large White Yorkshire X Landrace) pigs fed with swill feeding for a period of 5 months. Early-weaned crossbred piglets (n=24) were selected for this study, and the piglets were randomly divided into three equal groups; Group I, II, and III. The piglets were reared by following standard health coverage protocols. The feeds of Group I and II were supplemented with chromium in the form of chromium tripicolinate at 0.1 and 0.2 mg/kg of swill feed respectively, and Group III was kept as control. Carcass weight, carcass length, and bone percentage showed no significant difference among the three groups. However, better dressing percentage was observed in Group I (p<0.05). Liver and kidney weights were reduced in chromium supplemented groups (p<0.05). Chromium supplemented groups showed lower backfat thickness and fat percentage (p<0.01); whereas, loin eye areas and muscle percentage were increased as compared to the control group. Thus, it was concluded that chromium supplementation in feed of crossbred piglets influenced positively in their carcass traits.

The aim of current study was to assess the seroprevalence of Neospora (N.) caninum and Toxoplasma (T.) gondii infections in aborted cattle and subsequent estimation of role of these parasites in cattle abortion in Hamedan province, Iran. Blood samples (n=85) of aborted cattle were collected from different locations of Hamedan province for a period of two years from January, 2010 to December, 2012. All the samples were evaluated for the presence of IgG-antibodies against N. caninum and T. gondii using Enzyme Linked Immuno Sorbent Assay (ELISA). The results showed that 61.2% (n=52/85), 5.9% (n=5/85) and 3.5% (n=3/85) animals were positive for N. caninum, T. gondii and co-infection of these two, respectively. There was no significant correlation between seroprevalence rates, age groups and breeding (p>0.05). However, a significant difference was found between T. gondii infection and the type of cattle (p=0.05), unlike to N. caninum (p=0.52). This is the first report of N. caninum and T. gondii co-infection in cattle in Iran. Although the rate of T. gondii infection was lower but this parasite might partly be responsible to be transmitted to humans. Further investigations and appropriate control strategies in management of cattle farms are highly recommended.

A case of Trypanosoma congolense savannah type infection in a 4-year old German shepherd dog weighing 26-kg was presented to the Small Animal Clinic, University of Nairobi, Kenya, with the history of anorexia and difficulty in breathing. The clinical manifestations were fever, pale mucous membrane, dyspnea and wasting. Blood examination revealed the existence of trypanosome parasites, and showed mild anemia. Internal Transcribed Spacer (ITS) based polymerase chain reaction confirmed the presence of Trypanosoma congolense savannah type. Along with supporting therapy, the case was successfully managed using diminazene aceturate injection (dosed at 3.5 mg/kg body weight) through intramuscular route. Complete recovery of the case was observed on day 6 of post-treatment.

The comparative efficacy of Diazepam, Ketamine, and Ketamine-Diazepam combination was assessed in adult chickens. The chickens (n=30) were divided into three equal groups (G-1, G-2 and G-3), and were administered with Diazepam dosed at 0.5 mg/kg body weight (b.wt.), Ketamine HCL dosed at 20 mg/kg b.wt., and Ketamine HCL (dosed at 10 mg/kg b.wt.) combined with Diazepam (dosed at 2 mg/kg b.wt.) through intramuscular (IM) route. The means of induction period, duration of sedation or anesthesia, full recovery period and duration of analgesia were significantly (p≤0.05) differed among the groups. Also, the clinical and hematological parameters measured before and after the sedation or anesthesia within the groups were found to be differed significantly (p≤0.05) from each other. It was concluded that Diazepam dosed at 0.5 mg/kg b.wt. (IM) can be used in cockerels. However, combination of Ketamine (at 10 mg/kg IM)-Diazepam (at 2 mg/kg b.wt. IM) is preferably recommended as this combination is comparatively safer, and minimizes the pains elicited from the surgical procedure of using Diazepam alone.
