It should be noted that other seasonal coronaviruses that could cause symptomatic RTIs might be misdiagnosed clinically with COVID-19. Hence, we highly recommend monitoring and follow-up of symptomatic patients with negative SARS-COV-2 RT-PCR results.

The highest resistance and susceptibility among the isolates belonged to sulfamethoxazole-trimethoprim (68.5%) and meropenem (11.1%), respectively. The highest prevalence of multidrug-resistant (MDR) and ESBL were observed in E. coli and Proteus mirabilis isolates . Conclusion: In this study, the high frequency of MDR phenotypes in the isolates may suggest an increasing trend of antibiotic resistance in Enterobacteriaceae . This could greatly impact the management and treatment of infections caused by these drug-resistant bacteria. Therefore, infection-control measures and continuous monitoring is recommended for controlling the spread of ESBL-producing strains in different geographical areas.

Introduction: In HIV-associated tuberculosis cases, identifying nontuberculous Mycobacteria (NTM) from clinical samples has become essential regarding patients’ treatment and prognosis. This study aims to determine the prevalence of different Mycobacteria species from immunocompromised and immunocompetent patients with suspected tuberculosis attending a tertiary care hospital in Kolkata, India. Methods : Clinical samples from 112 suspected tuberculosis patients were examined by direct microscopy after Ziehl–Neelsen staining. After culture in BacT/ALERT 3D mycobacterial culture system, identification of the causative agents was performed using the GenoType MTCM system. Results: Culture positivity was higher in immunocompromised patients than in immunocompetent in both pulmonary and extrapulmonary samples. In smear-negative samples, culture positivity in immunocompromised patients (50%) was much higher than in immunocompetent patients (26.67%). Of 78 samples, four were NTMs (5.13%), including 1 M. avium , 1 M. abscessus, and 2 M. fortuitum , and 74 were Mycobacterium tuberculosis (MTBC). Two NTMs belonged to immunocompromised patients and two to immunocompetent individuals. The chance of Mycobacterial infection was higher in patients with a lower CD4 count. Both NTMs found in the immunocompromised group were from patients with a CD4 count<100. Conclusion: The present study showed that the MTBC is still the primary causative agent in pulmonary and extrapulmonary tuberculosis in this part of India.

Results: According to the antibiogram test, all isolates were MDR. In the presence of efflux pump inhibitor, a reduced resistance for tetracycline was observed, but not for ciprofloxacin. The AdeABC efflux pump genes were detected in all isolates. An increase in the AdeABC pump activity in four isolates was confirmed using AEBCM. Conclusion: AEBCM, a fast and convenient tool for assessing the ethidium bromide secretion in various bacteria, provides a quick diagnosis and treatment of multidrug-resistant bacteria.

Salmonellae are among the most common and the major causative agents of diarrhea in calves and humans. The present study was carried out to isolate and identify Salmonella in fecal samples of calves in industrial dairy farms of Hamedan and to determine antibiotic resistance profiles of the probable isolates. Methods: Salmonella were presumptively isolated based on the cultural characteristics and biochemical tests, and the identity of the isolates was further confirmed using genus- and serotype-specific PCR assays. Kirby-Bauer disk diffusion method was performed to determine antibiotic resistance profiles of the isolates. Results: Out of 120 stool samples collected from 8 industrial farms, 22 (18.33%) isolates possessing rfbJ , fliC and fljB genes were identified as Salmonella Typhimurium serotype. Antibiotic susceptibility test revealed all isolates (100%) were susceptible to gentamicin, amoxicillin-clavulanic acid, kanamycin, and ciprofloxacin and resistant against cotrimoxazole, cefazolin, and cefixime. Conclusion: To our knowledge, this study was the first report of Salmonella infection in Hamedan's dairy farms, indicating a relatively high prevalence rate of S . Typhimurium infection as the only detected serotype. Antibiotic resistance should also be considered a severe public health concern. Thus, effective hygiene measures should be adopted to prevent or reduce the infection, and monitoring antibiotic susceptibility is required to choose the drug of choice for treatment.

region of Sistan and Baluchestan Province, southeast of Iran. Methods: In this study, ticks were collected from 220 livestock, including 150 sheep, 50 goats, 20 cows in five counties of Sistan Province (Zabol, Zehak, Hirmand, Nimruz, and Hamun). The ticks were identified under a stereomicroscope according to valid morphological keys. A reverse transcription-polymerase chain reaction (RT-PCR) method was used to detect the CCHFV genome via amplifying the S segment. Results: Among 100 selected ticks, RT-PCR revealed no CCHFV infection. Conclusion: Although no ticks were positive for CCHFV, it should be recalled that Sistan and Baluchestan province is among the highly endemic CCHF foci. As a result, further investigation and larger sample sizes are required to confirm our outcome. According to the hypothesis that direct contact with viremic livestock is more significant than tick bites in the viral transmission, more serological and molecular screening should be performed on high-risk individuals, e.g., slaughterhouse staff, ranchers, farmers, and veterinarians in the Sistan region.

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV- 2) spilled over to humans via wild mammals, entering the host cell using angiotensin-converting enzyme 2 (ACE2) as receptor through Spike (S) protein binding. While SARS-CoV-2 became fully adapted to humans and globally spread, some mammal species were infected back. The present study evaluated the potential risk of mammals becoming hosts for SARS-CoV-2 through bioinformatics prediction based on ACE2 receptors.
