Retrospective Inspection and Dissemination Pattern of Common Metabolic Ailments among Hilly and Tarai Region Goats of Uttarakhand

Goats are considered as an important animal not in present scenario but also from ancient time. Due to increasing frugal interest of goat farming globally, profound animal husbandry practices are attaining importance under the target of obtaining quality products along with good animal health and welfare. During the transition phase of life, noticeable alterations in the endocrine and metabolic status of the dairy ruminants were registered. Among small ruminants i.e. goat’s hypocalcaemia, hypoglycemia/Pregnancy toxemia and hypomagnesaemia are the common metabolic disorders which normally precipitated during metabolic anxiety phase. The present study was conducted during the period of 1st January 2019 to 31st December 2019. During this period we had registered total 957 goats at Kalsi, Chakrata areas of district Dehradun, Chorgalia, Kotabagh, Kaladhungi areas of district Nainital and Shetlai, Pantnagar, Bazpur areas of district Uddham Singh Nagar beside this we had also included the concerned cases from Government Veterinary Hospital Outpatient departments (OPDs) of the above said areas in Uttarakhand. In the present study, we had performed a prevalence study over common occurring metabolic diseases of goats like hypocalcaemia, hypoglycemia/pregnancy toxemia and hypomagnesaemia. Besides this, we had also studied the dissemination pattern of common occurring metabolic diseases on the basis of their age groups and parity

Genomic profile of antibiotic resistant, classical ctxB positive Vibrio cholerae O1 biotype El Tor isolated in 2003 and 2005 from Puri, India: A retrospective study.

Objectives: To examine eight strains of Vibrio cholerae O1 isolated in 2003 and 2005 from Puri, India, for antibiotic susceptibility, presence of virulence and regulatory genes, cholera toxin (CT) production, CTX arrangement and genomic profiles. Materials and Methods: Bacterial strains were tested for antibiotic susceptibility using disc diffusion assay. Polymerase chain reaction determined the presence of antibiotic resistance, virulence and regulatory genes. To determine the type of cholera toxin subunit B (ctxB), nucleotide sequencing was performed. Southern hybridisation determined the number and arrangement of CTXΦ. Ribotyping and pulsed‑field gel electrophoresis (PFGE) were used to determine the genomic profile of isolates. Results: All the eight strains, except one strain, showed resistant to nalidixic acid, sulphamethoxazole, streptomycin and trimethoprim and possessed the sullI, strB, dfrA1 and intSXT genes. All the strains carried the toxin‑co‑regulated pilus pathogenicity island, the CTX genetic element, the repeat in toxin and produced CT. Restriction fragment length polymorphism (RFLP) analysis showed that V. cholerae O1 possess a single copy of the CTX element flanked by tandemly arranged RS element. Nucleotide sequencing of the ctxB gene showed the presence of classical ctxB. RFLP analysis of conserved rRNA gene showed two ribotype patterns. PFGE analysis also showed at least three PFGE patterns, irrespective of year of isolations, indicating the genomic relatedness among them. Conclusion: Overall, these data suggest that classical ctxB‑positive V. cholerae O1 El Tor strains that appeared in 2003 continue to cause infection in 2005 in Puri, India, and belong to identical ribotype(s) and/or pulsotype(s). There is need to continuous monitor the emergence of variant of El Tor because it will improve our understanding of the evolution of new clones of variant of V. cholerae.

Characteristics of Vibrio cholerae O1 isolated from water of the River Ganga, Varanasi, India.

Background: Vibrio cholerae is an autochthonous inhabitant of fresh and brackish water and estuarine system. Investigation of V. cholerae from the River Ganga seems important to find variation in CTX arrangement and genomic diversity. Objectives: To investigate V. cholerae O1 strains for the presence of virulence and regulatory genes, variation in number and organisation of the pre‑CTXФ and/or CTXФ, and for the genomic diversity. Materials and Methods: Polymerase chain reaction (PCR) was used to detect virulence and regulatory genes, type of rstR and location of CTXΦ on the chromosome. Southern hybridisation was conducted to see the number and arrangement of pre‑CTXΦ and CTXΦ. Ribotyping and pulsed‑field gel electrophoresis were used to find genetic relatedness. Results: Seven strains gave positive results by PCR for the gene encoding for ctxA, zot, ace, tcpA (El Tor), ompU, and toxR, except one strain that was negative for the ctxA. Three strains were positive for the tcpA (El Tor), ompU and toxR genes. Determination of CTX organisation showed that among the ctx‑positive strains, four harboured two copies of CTXETФ arranged in tandem and two harboured one copy of CTXETФ, and one ctx‑negative strain harboured only one copy of pre‑CTXETФ. Pulsotype and ribotype analysis showed existence of at least three pulsotype and ribotypes indicating diversity in genomic content among them. Conclusion: This study thus indicates that multiple clones (ribotypes/pulsotypes) of V. cholerae O1 carrying pre‑CTXΦ and/or CTXΦ and ctx‑negative strains were present in the water of the River Ganga, Varanasi, India.

A case report of an uncommon phaeoid fungal infection in nasal polyposis and review of literature.

Nasal polyposis is an inflammatory condition of mucous membrane of the nose and paranasal sinuses with unknown aetiology. Massive nasal polyps can obstruct the nasal cavity causing discomfort and lowered quality of life. Thus, aetiological diagnosis is important for treatment, especially in recurrent nasal polyposis. We present a rare case of pansinusitis with bilateral ethmoidal polyps caused by an unusual phaeoid fungus Fonsecaea pedrosoi in a 65-year-old immunocompetent male from a rural background. The diagnosis was made by endoscopic nasal examination; high resolution computed tomography of the paranasal sinuses, detection of fungal hyphae in 10% potassium hydroxide wet mount and culture.

Emergence and dissemination of antibiotic resistance: A global problem.

Antibiotic resistance is a major problem in clinical health settings. Interestingly the origin of many of antibiotic resistance mechanisms can be traced back to non-pathogenic environmental organisms. Important factors leading to the emergence and spread of antibiotic resistance include absence of regulation in the use of antibiotics, improper waste disposal and associated transmission of antibiotic resistance genes in the community through commensals. In this review, we discussed the impact of globalisation on the transmission of antibiotic resistance genes in bacteria through immigration and export/import of foodstuff. The significance of surveillance to define appropriate use of antibiotics in the clinic has been included as an important preventive measure.

Profile of Ocular Trauma at Tertiary Eye Centr

This prospective study reveals the epidemiological profile of ocular trauma referred to a tertiary eye centre over one year. All consecutive patients referred to Vitreo-retina service during 1 year period were examined.Out of total 523 eyes registered large proportion was <25years of age (67%), males (88%) and literate (77%). Forty-four percent belonged to rural area and 38% were students. Most of the open globe injuries were Zone 1(50.8%). 75% presented >1 week after injury. The incidence of intraocular foreign body and retinal detachment was 17.4, and 11.3% respectively. Diagnosis of post traumatic endophthalmitis was made in 20.5% of open globe injuries. Development of endophthalmitis correlated with younger age, rural setting, illiteracy, presence of foreign body and lens disruption. Ocular trauma requiring tertiary care commonly affects young students, labourers and factory workers. Younger, rural and illiterate patients are more likely to develop infection especially if they have lens injury or intraocular foreign body.

Cranial vault salmonella osteomyelitis leading to extradural abscess - A case report.

A case of rarely encountered Salmonella typhi osteomyelitis of left occipital bone leading to extradural abscess, is reported. The causative organism was not suspected until the culture report was obtained. The patient responded promptly to surgical drainage and antibiotic therapy.

Carbofuran induced impairment in the hypothalamo-neurohypophyseal-gonadal complex in the teleost, Channa punctalus (Bloch).

The effect of chronic exposure to carbofuran (4.5 ppm in static water) for six months on the gonadal histophysiology and hypothalamo-neurohypophyseal complex was studied in Channa punctatus. Experimental observations revealed significant inhibition of gonadal development with associated degenerative abnormalities as evidenced by ovarian and testicular histology and reduced gonadosomatic index. Degenerative changes in ovary were exihibited by stage I (oogonium) and stage II (immature/non-vitellogenic) oocytes as marked by perinuclear ooplasmic lysis, clumping and dissolution resulting in disintigration of nuclear material altogether attributed to complete degeneration of such oocytes. Testicular deleterious changes included degeneration of spermatogenic elements and necrosis of interstitial cells of Leydig. Correlative histophysiological changes were also observed in the pituitary gonadotrophs and hypothalamic, nucleus pre-opticus, neurons that were smaller, inactive and less in number with associated necrosis. Corresponding to the changes in nucleus pre-opticus neurons, significant inhibition of brain monoamine oxidase enzyme activity was also recorded in treated group. These observations suggest that carbofuran even at low concentration level under long-term exposure is capable of inducing retardation of gonadal development which might have been mediated through the impairment of the hypothalamo-neurohypophyseal-gonadal axis in this species.

Production of heat-labile enterotoxin by strains of Aeromonas veronii bv veronii.

Three isolates of Aeromonas veronii bv veronii (2 environmental, one blood infection) were examined to see if they produce any enterotoxin and, if so, to determine its characteristics. Two isolates caused fluid accumulation in the initial rabbit ileal loop tests. The other strain did so after a single passage through the rabbit ileal loop. All the isolates showed gradual enhancement of fluid secretion after each subsequent passage. Inocula of 1 x 10(4) viable cells and 0.25 mL of culture filtrate caused fluid accumulation comparable to those of toxigenic Vibrio cholerae 569B. The enterotoxic activity was inactivated at higher temperature, and showed biological activity over a wide range of pH. The only histopathological change observed was depletion of mucous from goblet cells. The findings of the study indicate that strains of A. veronii bv veronii produce a heat-labile, pH-stable diarrhoeagenic factor without causing any damage to the intestinal mucosa.

Enterotoxicity, haemolytic activity and antibiotic susceptibility of Aeromonas eucrenophila strains isolated from water and infected fish.

Strains of A. eucrenophila isolated from fresh water (2 strains) and infected fish (4 strains) were tested for haemolytic activity and enterotoxicity and any correlation between them. Also, the resistance patterns of A. eucrenophila were tested especially in relation to ampicillin. None of the A. eucrenophila strains caused fluid accumulation in the initial tests, however, they did so only after one to four sequential passages through the gut of a susceptible host. All the strains of A. eucrenophila showed beta-haemolytic activities. Production of beta-haemolysin could be correlated with enterotoxicity. Since all the strains of A. eucrenophila were resistant to ampicillin, media containing this antibiotic may be used for their isolation from diverse sources.

Synthesis of L-asparaginase by Serratia marcescens (Nima).

The production of L-asparaginase by two mutants of Serratia marcescens grown on 14 different media was studied. The enzyme content increased from trace levels to 2·4 international units per ml when the organisms were grown in glycerol-peptone yeast extract medium. Glucose was the best carbon source under aerobic conditions. The enzyme content increased when L-asparagine was present in the growth medium.

An actinomycete producing L-3,4-dihydroxyphenylalanine from L-tyrosine.

An actinomycete was isolated during a soil screening programme to obtain L-3,4-dihydroxyphenylalanine producers. A mutant of this organism was isolated by chemical mutagenesis and it accumulated 1 g/litre L-dihydroxyphenylalanine when grown on L-tyrosine. Resting cells converted 30% of tyrosine in the reaction mixture. The use of resting cells for dihydroxyphenylalanine production is advantageous as it eliminates interfering substances which accumulate during fermentation.
