Background: The current study determined microbial flora in bile aspirates from patients undergoing cholecystectomy along with antibiotic susceptibility pattern and resistance mechanism viz. extended spectrum β-lactamase (ESBL).Methods: The study included 110 such patients which were divided in three groups as: Group A that included acute cholecystitis with or without cholelithiasis, Group B included chronic cholecystitis with or without cholelithiasis and Group C included other hepatobiliary ailments requiring cholecystectomy viz. gallbladder carcinoma, acute emphysematous gall bladder and mucocele gall bladder. The bile was subjected to complete microbiological and histopathological examination. Antimicrobial susceptibility of the isolates was performed as per CLSI guidelines.Results: Bacteria were recovered from 07 samples (20%) in Group A, 17 (48.57%) in Group B and 11 (31.43%) in Group C. The polymicrobial infection was seen in 04 (11.43%) patients. The most common organisms isolated were Escherichia coli 15 (38.46%), Klebsiella pneumoniae and Pseudomonas aeruginosa 8 (20.51% each). The majority of Enterobacteriaceae isolates were susceptible to piperacillin-tazobactam and carbapenems. The ESBL production was observed in 17 (43.58%) isolates.Conclusions: Therefore, antimicrobial susceptibility of potential causative organisms, presence of resistant strains in bile, the severity of the cholecystitis, and the local susceptibility pattern must be taken into consideration while prescribing antibiotics. A protocol regarding the management of such cases should be formulated based on observations of similar studies.

Objective: To compare the frequency of port site wound infection following gall bladder removal through umbilical and epigastric port in laparoscopic cholecystectomy. Study Design: Randomized Control Trial. Setting: Surgical Unit 2, Ghulam Muhammad Mahar Medical College, hospital Sukkur. Period: 1st November 2019 to 30th October 2020. Material & Methods: All cases who underwent four port laparoscopic cholecystectomy were enrolled in two groups. All procedures were performed under general anesthesia. As the last event of surgery gall bladder was retrieved in a glove bag through umbilical port in group A and through epigastric port in group B, both under direct camera vision. Wound infection was considered if there was 3 to 5 grade of wound according to Southampton wound grading system (Figure-1) on 5th postoperative day. All demographics and outcome variables were recorded. Results: Age ranged from 20 to 60 years with mean age of 38.875±8.11 years, BMI 29.973±5.12 Kg/m2, duration of surgery 50.656±8.41 mins and Southampton score was 1.044±1.07 in Group A and mean age of 38.560±6.23 years, BMI 27.437±5.04 Kg/m2, duration of surgery 48.920±8.67 mins and Southampton score was 0.856±0.92 in Group B. In group A, 18 (5.7%)patients developed port site wound infection in contrast to 5 (1.6%) patients in group B (P= 0.006). Conclusion: We conclude that epigastric port retrieval of gall bladder following laparoscopic cholecystectomy results in less port site infection.

Transmissible Venereal Tumour

Background: Canine transmissible venereal tumour (CTVT) also known as infectious sarcoma, venereal granuloma, transmissible lymphosarcoma or sticker tumour is usually transmitted through coitus and mainly affects the external genitalia of young sexually matured dogs. Surgery, chemotherapy, radiotherapy and immunotherapy are considered as effective treatment protocols. Therefore, depending upon the availability present study was designed to investigate the efficacy of different surgico-chemotherapeutic protocols for treatment of canine transmissible venereal tumour.Methods: The study was conducted during January 2018 to July 2018 at the Teaching Veterinary Clinical Complex (TVCC) and Department of Veterinary Surgery and Radiology, College of Veterinary Science and A.H., Anjora, Durg (C.G.) on 18 canines of various breed, irrespective of age, sex and divided into three groups consisting 6 animals in each group. Group A was treated with surgical excision of tumour only where as Group B and Group C were treated with surgical excision of tumour followed by administration of Doxorubicin (30mg/m2) BSA and Vincristine sulphate (0.025 mg/kg) intravenously alongwith DNS at 7th and 14th post-operative days respectively. Different physiological and haemato-biochemical parameters (Hb, PCV, TLC, TPC, DLC, serum glucose, TSP, SUN, SC, ALT, AST and ALP) were recorded preoperatively, postoperatively and after chemotherapy at 10th, 30th and 60th days intervals.Result: The present investigation showed transient changes in physiological and haemato-biochemical parameters before, post surgery and post chemotherapeutic management and was within normal range. Histopathological examination revealed confluent sheet of tumour cells arranged in large round oval or polyhedral shaped distributed in tight clusters or cords. Group A showed mild to moderated reoccurrence while Group B showed minimum reoccurrence. Group C showed no reoccurrence. Thus, surgery combined with vincristine therapy is most effective for treating dogs suffering with transmissible venereal tumour.

Background: Group B streptococcus (GBS) is one of the important cause of early onset neonatal sepsis in developed countries leading to increased neonatal morbidity and mortality. Penicillin and Ampicillin are the drugs of choice for prevention of GBS infections. Antibiotic resistance amongst GBS isolates is an emerging health problem affecting neonates. Hence, this study was performed to determine the antibiotic susceptibility pattern of Group B Streptococcus (GBS) in a population of pregnant women.Methods: A prospective study was done to screen pregnant women for vaginal and rectal GBS colonization during their regular visits to antenatal clinic. Todd-Hewitt broth, an enrichment medium for GBS was used for isolation. The antibiotic susceptibility pattern of the isolates were studied.  Results: A total of 300 pregnant women were screened for GBS colonization. GBS colonization rate in our study was 2.3%. The antibiotic susceptibility pattern of the isolates revealed that none of the isolates were resistant to penicillin or clindamycin, while resistance was noted to erythromycin (14.3%) and   tetracycline (71.4%).Conclusions: GBS continues to remain sensitive to Penicillin which is the drug of choice for prevention and treatment of GBS.  Consistent surveillance of antibiotic sensitivity pattern of GBS as well as for other organisms implicated in new born sepsis and maternal infections is required to formulate guidelines for prevention and treatment.

BACKGROUND: Group B Streptococcus (GBS) is recognized as an important cause of maternal and neonatal morbidity and mortality. Maternal vaginal carriage of GBS (Streptococcus agalactiae) can lead to vertical transmission to the neonate at the time of delivery. However, little is known about its prevalence, predictors and antibiotic susceptibility pattern in Jimma, Ethiopia. This study assessed the prevalence, antimicrobial susceptibility pattern and determinants of GBS recto-vaginal colonization among near-term pregnant women.METHODS: A cross-sectional study was conducted from May to August 2015 at Jimma University Medical Centre in Southwest Ethiopia. Data through questionnaire and GBS isolates from vaginal and rectal swabs were collected. Antimicrobial susceptibility testing was performed.RESULTS: The overall prevalence of GBS colonization among near term pregnant women (35-37 weeks) was 16.3% (22/135). The majority of GBS isolates were sensitive to Ampicillin and Penicillin G with 95.5% and 90.1%, respectively. Erythromycin and clindamycin were resisted by 50% and 40.9% of the isolates, respectively, whereas gentamicin was resisted by all isolates. GBS colonization was significantly associated with a history of preterm delivery (PTD) (AOR: 6.3, 95% CI: 1.42, 28.3) and history of urinary tract infection (UTI) during current pregnancy (AOR: 6.4, 95% CI, 1.95, 21.1).CONCLUSION: Our study indicated that one among six near-term pregnant women had recto-vaginal GBS colonization. In places where universal screening is not feasible, selective screening for factors particularly history of PTD and UTI during current pregnancy may be a reasonable option. Antibiotic susceptibility testing should be performed while using Erythromycin, Clindamycin or Gentamicin.

Wound infections result in sepsis, limb loss, long hospital stays, higher costs, and are responsible for significant human mortality and morbidity worldwide. The present study was conducted to isolate and identify the causative organisms of wound infection, to determine the antibiotic susceptibility pattern of the isolates and to study the risk factors for wound infection. The study was conducted for six months in which pus specimens collected from 244 patients were processed to investigate etiological agents using standard technique. Disc susceptibility of bacterial agents were then determined. A total of 244 pus samples were collected and 147 (60.20%) samples showed growth. A total of 150 bacterial isolates were isolated; of which 118 (78.67%) were Gram positive and 32 (21.33%) were Gram negative bacteria. Staphylococcus aureus (72.00%) was most common followed by Escherichia coli (6.67%), Citrobacter freundii (5.34%), Staphylococcus epidermidis (4.00%), Pseudomonas aeruginosa (3.33%), Proteus mirabilis (2.00%), Enterococcus faecalis (1.33%), Acinetobacter spp. (1.33%), Klebsiella oxytoca (1.33%), Klebsiella pneumoniae (1.33%), Streptococcus pneumoniae (0.67%) and Streptococcus pyogenes (0.67%). The most effective antibiotic for Gram positive isolates was Gentamicin (77.97%). For Gram negative isolates (except Ps. aeruginosa), Amikacin (74.07%), for Ps. aeruginosa, Amikacin, Ciprofloxacin, Gentamicin and Ofloxacin each with the susceptibility of 80.00% and for Staph. aureus, Cloxacillin (79.63%) were the most effective antibiotics. Hence, the most common isolate in wound infection was Staph. aureus followed by E. coli. Therefore, routine microbiological analysis of the wound specimens and their antibiotic susceptibility testing is recommended that will guide clinician for treatment of wound infection.

Background: Diabetes mellitus and its complications are rising. Managing the diabetic foot wound is very challenging. Early intervention and intense management using modern technique will improve the diabetic wounds for a definitive procedure and also prevent, reduce the level of amputation of extremity. Our study compares the microbiological and histopathological results of diabetic wounds managed by conventional dressing and VAC (vacuum assisted closure) therapy.Methods: This was an institutional based prospective study conducted between July 2018 and July 2019 consisting of 50 patients with diabetic wound of lower extremities. Patients were divided into group A- 25 patients underwent conventional dressing and group B- 25 patients underwent negative pressure wound therapy (NPWT). Wound swab and tissue biopsy was obtained on day 0 and day 10 from both groups and compared.Results: Among patients, 76% and 24% were males and females respectively. Histopathologically, necrosis and inflammatory cell infiltrate were significantly decreased in group B compared to group A. Angiogenesis increased notably in group B. On microbiological grounds, from both groups Pseudomonas aeruginosa was found to be the most common organism on day 0 and 10. But the prevalence of infection in group B was grossly reduced when compared to group A.Conclusions: VAC therapy is a better modality to treat diabetic wound compared to conventional dressing as it accelerates the healing of a chronic wound by increasing angiogenesis and decreasing necrosis, inflammatory cell infiltrate and microbial growth.

This study was carried out to evaluate the efficacy of vaccination of layer chickens with inactivated FC bacterin prepared from local Egyptian strains of Pasteurella multocida (P. multocida). A total of 200 layer chickens were divided into 5 equal groups, 40 for each. At the age of 6 weeks, chickens in groups (A) and (B) were vaccinated with P. multocida serotypes A:1 and A:3, respectively, booster doses were given after 3 weeks (9 weeks old) and challenge was done with virulent serotypes A:1 and A:3 at 2 weeks later (11 weeks old). Chickens in groups (C) and (D) were not vaccinated, only challenged with P. multocida serotype A:1 and A:3, respectively. Birds in group (E) were kept as non-vaccinated and non-challenged. Blood samples were collected weekly from all groups for humoral immune response. All the birds were kept under observation for signs, mortalities, lesions and re-isolation of challenging organism and for histopathological examination. Results of the mean Enzyme Linked Immuno-Sorbent Assay (ELISA) revealed that the highest level was at 5 weeks post vaccination as the titers reached to 3970 in group (A) and 3905 in group (B). The clinical signs, mortality rate and lesions were mild in the vaccinated birds while severe lesions were in non-vaccinated and challenged birds. The protection rates were 85 % and 80 % in groups (A) and (B); respectively, while 10 % and 20 % in groups (C) and (D); respectively. The re-isolation rates of P. multocida after challenge were 95 % and 90 % in non-vaccinated-challenged birds with P. multocida serotypes A:1 and A:3; respectively, while they were 25 % and 15 % in vaccinated-challenged groups with P. multocida serotypes A:1 and A:3; respectively. Histopathological examination of P. multocida vaccinated-challenged birds revealed mild to no microscopic lesions when compared with non-vaccinated challenged chickens. In conclusion, the prepared FC inactivated bacterin from the local Egyptian predominant P. multocida serovars proved efficacy and protection of layer chickens. Key words: Pasteurella multocida; chickens; immunization; protection; Egypt UČINKOVITOST CEPLJENJA KOKOŠI NESNIC Z INAKTIVIRANO BAKTERIJO KOLERE PERJADI, PRIPRAVLJENE IZ LOKALNIH EGIPTOVSKIH SEVOV BAKTERIJE Pasteurella multocida Povzetek: Raziskava je bila izvedena z namenom ocenitve učinkovitosti cepljenja kokoši nesnic z inaktivirano bakterijo FC, pripravljeno iz lokalnih egiptovskih sevov bakterije Pasteurella multocida (P. multocida). Skupno 200 kokoši nesnic je bilo razdeljenih v 5 enakih skupin. V vsaki skupini je bilo 40 kokoši. Pri 6 tednih smo kokoši v skupinah A in B cepili s serotipoma P. multocida A:1 in A:3, po 3 tednih, ko so bile živali stare 9 tednov, so dobile poživitvene doze cepiva. Po dveh tednih (v starosti 11 tednov) so bile kokoši okužene z virulentnima serotipoma A:1 in A:3. Piščanci v skupinah C in D niso bili cepljeni temveč samo okuženi s serotipoma A:1 in A:3. Kokoši v skupini E niso bile niti cepljene, niti okužene. Vzorci krvi so bili odvzeti pri vseh skupinah tedensko za preverjanje humoralnega imunskega odziva. Vse kokoši smo stalno opazovali in beležili prisotnost bolezenskih znakov, različnih ran in umiranje kokoši. Pri poginulih kokoših smo osamili bakterije ter opravili histopatološki pregled. Rezultati encimsko-imunskega testa (ELISA) so pokazali da je bila najvišja stopnja zaščite dosežena 5 tednov po cepljenju, saj so titri dosegli 3970 v skupini A in 3905 v skupini B. Klinični znaki, stopnja umrljivosti in rane so bili pri cepljenih kokoših blagi, hude rane pa so bile vidne pri necepljenih in okuženih kokoših. Stopnja zaščite je bila v skupinah A in B 85- oziroma 80-odstotna, v skupinah C in D pa 10- oziroma 20-odstotna. Stopnje ponovne izolacije P. multocida po okužbi so bile 90 in 95 odstotkov pri kokoših, ki niso bile cepljene, medtem, ko so bile v skupinah, ki so bile okužene s P. multocida serotipa A:1 in A:3 15- in 25-odstotkov. Histopatološki pregled cepljenih in okuženih kokoši je pokazal popolno odsotnost ali prisotnost blagih mikroskopskih poškodb, medtem ko so imele necepljene okužene kokoši bolj obsežne histopatološke poškodbe. Pripravljena inaktivirana bakterija FC iz lokalnih egiptovskih prevladujočih serovarov P. multocide se je izkazala za učinkovito zaščito kokoši nesnic.Ključne besede: Pasteurella multocida; kokoši; imunizacija; zaščita; Egipt

A total of 5,134 strains of Xanthomonas campestris pv. vesicatoria obtained from diseased pepper and tomato fruits at 22 diverse locations on the East Caribbean islands of Antigua, St. Christopher, St. Lucia, and Grenada were assessed for pathogenicity, taxonomic group phenotypes, and sensitivity to copper, zinc, and streptomycin. Altogether, 15 known races, namely T1, T2, P0T1, P0T2, P1T1, P1T2, P2T1, P2T2, P3T1, P3T2, P4T2, P5T2, P5T3, P6T2, and P6T3, were detected. Races T1, P0T1, P0T2, P1T2, P2T1, and P3T1 were common to all islands except St. Lucia. St. Lucia had races P2T2, P3T2, P4T2, and P6T2 in common with Grenada and two races each from among the four pathotypes in common with Antigua and St. Lucia. Races T1, P1T2, P3T1, and P3T2 were the most abundant strains of the bacterium in Antigua, whereas the two latter pathotypes, as well as races P0T1 and P2T1, were among the most prevalent strains in St. Christopher. In contrast, races P6T2 and P5T2 predominated in St. Lucia, and P6T2, P1T2, and P3T2 were the abundant pathotypes in Grenada. Generally, the largest bacterial spot fruit lesions were associated with the predominant races on each island, and the smallest lesions were generally linked to races capable of overcoming gene Bs2. Only these latter races were similar to group B strains of X. campestris pv. vesicatoria with respect to the presence of β-protein in their cellular protein profiles, ability to hydrolyze starch, and inability to oxidize cis-aconitate. Other race types tested resembled group A strains of the bacterium in their ability to utilize cis-aconitate, inability to hydrolyze starch and pectate, and the presence of the α-protein in profiles of cellular proteins. Copper-resistant strains of X. campestris pv. vesi-catoria constitute 8.7 to 10.6% of the pathogen collections from Antigua and St. Christopher and 44.4 and 66.7% of pathotypes from St. Lucia and Grenada, respectively. Almost all strains were sensitive to zinc. Streptomycin resistance was observed among 62% of the strains in St. Christopher and Grenada and 62.8 to 83.6% of those in Antigua and St. Lucia.
